poultry feed mill equipment - poultry feed formulation
A feed production mill is a must have if you are planning to make your own poultry feeds at home or in a small industrial plant. Feed milling equipment consists of various components. These include the feed grinding machine, a feed mixing machine, the feed pellet machine, the feed pellet cooling machine as well as a feed pellet packing machine.
Apart from these core poultry feed mill equipment, there are also auxiliary feed mill equipment that make all this function together as a unit. These including the conveying machine or a system of conveyance belts, a control cabinet, dust collectors, storage bins, fire protection equipment and many others. It all depends on how well equipped and sophisticated you want your poultry feed milling plant to be.
For more information on how this entire system works during the feed processing, check out our post on the poultry feed production line that explains what happens in every component. If you are going to establish poultry feed production line or milling plant, you will have to purchase all these machine components and install them on your production floor with some technical assistance.
The poultry feed mill is equipped to receive various kinds of raw materials. Depending on the design of the poultry mill, the plant line can receive either a truck or rail delivery and sometimes, it can receive both deliveries.
The various ingredients to be used in processing the poultry feed such as the grains, fats, fish meal, pre-mixes and molasses are delivered to the plant by trucks. The grains and soybean meal are generally delivered by rail.
The dry ingredients to be used in formulating the poultry feeds can be received in bags or in bulk. The liquid ingredients to be used in poultry feed formulation such as molasses and fat can be pumped directly into the storage tank in the feed mill line.
The solid grains must be ground in the feed mill by the poultry feed grinder or the feed hammer mill. This is done before the feed is mixed with the other feed ingredients to be used in the poultry feed formulation.
During the feed formulation, the various ingredients being used to make the poultry feed must be weighed quantitatively, in batches. The quantity of the various ingredients that you will feed into the feed mill scale hopper is to be controlled from a central console. This can be done either automatically or manually with aim of ensuring that you feed in the correct ratio for each ingredient.
The mixing is done by the feed mixer in the poultry feed mill. The feed mixing will uniformly mix all the individual ingredients being used in the poultry feed formulation. The mixing time will depend on the property of the feed ingredients being used as well as feed formulation for the particular poultry feed that you are making.
During the pelleting stage, the mixed/blended feed ingredients are fed into the pelleting machine in the production line. The pelleting process involves various stages. The mixture of feed ingredients goes into the pellet mill feeder. This will control the rate at which the feed ingredients mixture mixture will enter the feed pelleting equipment.
The next process at the pelleting stage involves the blending together of the dry mixed materials withs team in order to create a wet mesh. It this wet mash that is fed to the mill pelleting machine. It can be pushed here either through gravity or via a forced feeder system.
The pelletized poultry feed are finally cool before packaging. The hot feed mixture is feed into the pellet cooling machine by gravity. The cooling is done in order to get durable and hard pellets. Once the pellets are cooled, they will flow into the screening machine where there is the scalping of the pelleted mash into the fines and mash.
The poultry feed mill should be maintained well and on a regular basis in order to improve its operational efficiency as well as the quality of the feed produced. Proper maintenance will also reduce the instances of feed contamination during processing.
There are various kinds of maintenance that you can perform on your poultry feed mill. These include the emergency maintenance, routine maintenance, the call-in maintenance as well as preventive maintenance.
The routine maintenance for your poultry feed mill is the scheduled maintenance that you carry out regularly based on a fixed routine. Typical routine maintenance work includes activities such as the lubrication of the bearings, replacing the hammer mill screens, replacing the worn out parts of the poultry feed mill equipment or checking the oil levels in the poultry feed mill gear boxes.
Preventive maintenance for the poultry feed mill machine involves making certain adjustments and carrying out inspections and repairs on the equipment. This involves activities such as repairing the worn out parts before they fail based on observation in order to forestall further damage and ensure the feed mill machine is working smoothly.

measuring vibration: the complete guide | brel & kjr
As vibration isolation and reduction techniques have become an integral part of machine design, the need for accurate measurement and analysis of mechanical vibration has grown. Using accelerometers to convert vibratory motion into an electrical signal, the process of measurement and analysis is ably performed by the versatile abilities of modern electronics.
A body is said to vibrate when it describes an oscillating motion about a reference position. The number of times a complete motion cycle takes place during the period of a second is called the frequency and is measured in hertz (Hz).
The motion can consist of a single component occurring at a single frequency, as with a tuning fork, or of several components occurring at different frequencies simultaneously, for example, with the piston motion of an internal combustion engine.
Vibration signals in practice usually consist of very many frequencies occurring simultaneously so that we cannot immediately see just by looking at the amplitude-time pattern, how many components there are, and at what frequencies they occur.
These components can be revealed by plotting vibration amplitude against frequency. The breaking down of vibration signals into individual frequency components is called frequency analysis, a technique which may be considered the cornerstone of diagnostic vibration measurements. The graph showing the vibration level as a function of frequency is called a frequency spectrogram.
When frequency analyzing machine vibrations, we normally find several prominent periodic frequency components that are directly related to the fundamental movements of various parts of the machine. With frequency analysis, we are therefore able to track down the source of undesirable vibration.
In practice, it is very difficult to avoid vibration. It usually occurs because of the dynamic effects of manufacturing tolerances, clearances, rolling and rubbing contact between machine parts, and out-of-balance forces in rotating and reciprocating members. Often, small insignificant vibrations can excite the resonant frequencies of some other structural parts and be amplified into major vibration and noise sources.
Sometimes though, mechanical vibration performs a useful job. For example, we generate vibration intentionally in component feeders, concrete compactors, ultrasonic cleaning baths, rock drills, and pile drivers. Vibration testing machines are used extensively to impart a controlled level of vibration energy to products and sub-assemblies where it is required to examine their physical or functional response and ascertain their resistibility to vibration environments.
A fundamental requirement in all vibration work, whether it is in the design of machines that utilize its energies or in the creation and maintenance of smoothly running mechanical products, is the ability to obtain an accurate description of the vibration by measurement and analysis.
The vibration amplitude, which is the characteristic that describes the severity of the vibration, can be quantified in several ways. On the diagram, the relationship between the peak-to-peak level, the peak level, the average level, and the RMS level of a sinewave is shown.
The peak-to-peak value is valuable in that it indicates the maximum excursion of the wave, a useful quantity where, for example, the vibratory displacement of a machine part is critical for maximum stress or mechanical clearance considerations.
The peak value is particularly valuable for indicating the level of short duration shocks etc. But, as can be seen from the drawing, peak values only indicate what maximum level has occurred, no account is taken of the time history of the wave.
The rectified average value, on the other hand, does take the time history of the wave into account but is considered of limited practical interest because it has no direct relationship with any useful physical quantity.
The RMS value is the most relevant measure of amplitude because it both takes the time history of the wave into account and gives an amplitude value that is directly related to the energy content, and therefore the destructive abilities of the vibration.
When we looked at the vibrating tuning fork, we considered the amplitude of the wave as the physical displacement of the fork ends to either side of the rest position. In addition to Displacement, we can also describe the movement of the fork leg in terms of its velocity and its acceleration. The form and period of the vibration remain the same whether it is the displacement, velocity, or acceleration that is being considered. The main difference is that there is a phase difference between the amplitude-time curves of the three parameters as shown in the drawing.
For sinusoidal signals, displacement, velocity, and acceleration amplitudes are related mathematically by a function of frequency and time, this is shown graphically in the diagram. If the phase is neglected, as is always the case when making time-average measurements, then the velocity level can be obtained by dividing the acceleration signal by a factor proportional to frequency, and the displacement can be obtained by dividing the acceleration signal by a factor proportional to the square of the frequency. This division is performed digitally in the measuring instrumentation.
The vibration parameters are almost universally measured in metric units following ISO requirements, these are shown in the table. However, the gravitational constant "g" or maybe more correctly "gn" is still widely used for acceleration levels although it is outside the ISO system of coherent units. Fortunately, a factor of almost 10 (9,80665) relates the [MOP1] two units so that mental conversion within 2% is a simple matter.
By detecting vibratory acceleration, we are not tied to that parameter alone. We can convert the acceleration signal to velocity and displacement. Most modern vibration meters are equipped to measure all three parameters.
Where a single, wide frequency band vibration measurement is made, the choice of parameter is important if the signal has components at many frequencies. Measurement of displacement will give the low-frequency components the most weight, and conversely, acceleration measurements will weigh the level towards the high-frequency components.
Experience has shown that the overall RMS value of vibration velocity measured over the range of 10 to 1000 Hz gives the best indication of a vibration's severity on rotating machines. A probable explanation is that a given velocity level corresponds to a given energy level; vibration at low and high frequencies are weighted equally from a vibration energy point of view. In practice, many machines have a reasonably flat velocity spectrum.
Performing narrow-band frequency analysis, the choice of the parameter will be reflected only in the way the analysis is tilted on the display or print (as demonstrated in the middle diagram on the opposite page). This leads us to a practical consideration that can influence the choice of parameter. It is advantageous to select the parameter which gives the flattest frequency spectrum to best utilize the dynamic range (the difference between the smallest and largest values that can be measured) of the instrumentation. For this reason, the velocity or acceleration parameter is normally selected for frequency analysis purposes.
The nature of mechanical systems is such that appreciable displacements only occur at low frequencies; therefore, displacement measurements are of limited value in the general study of mechanical vibration. Where small clearances between machine elements are being considered, vibratory displacement is of course an important consideration. Displacement is often used as an indicator of unbalance in rotating machine parts because relatively large displacements usually occur at the shaft rotational frequency, which is also the frequency of greatest interest for balancing purposes.

beef meat processing steps, technology, equipment and beef products
Beef is the culinary name for meat from bovines, especially cattle. Beef is an excellent source of protein and vitamin B12 and a very good source of zinc and selenium. In addition, beef is a good source of riboflavin, vitamin B6, niacin, iron and phosphorous. Do you know that the delicious, nutritious beef meat on the table is the result of various physical and chemical treatment methods?
1. Beef meat processing involves a number of steps from the animal to the beef meat.
The first step in beef meat processing is slaughter. Before slaughter, a technician examines the animal to make sure it is fit for human consumption. If the animal appears healthy, the animal is slaughtered. A stunning device renders the animal senseless, a worker slits the throat and then the animal is hung by its hind feet to bleed. The blood is allowed to drain, and then workers skin the animal and remove its head. Skinning is done with care, keeping it in one piece so the hide can be sold for leather goods manufacturing. After skinning, they open the carcass to remove the internal organs and split the carcass in half. They spray the carcass with water to rinse away the blood and bone chips caused by the saws.
2. The second step is aging. The beef is tagged and hung in a large cooler, where it will hang for about a week for aging in order to improve the flavor of the beef and makes it tenderer. Aging allows enzymes to break down the meat.
3. The third step in beef meat processing is beef cutting. The processor can cut beef according to the end beef products. And the beef cuts can be handled in a variety of ways, such as smoking, salting, pickling, or ground for hamburger or sausage, etc.
Besides the above beef meat processing stages, the beef cuts processing involves a wide range of treatments, including the following processing technologies: chopping, seasoning, mixing or tumbling, stuffing into casings, and smoking, etc. and along with the utilization of modern specialized meat processing equipment, like meat grinding machine, brine injector, meat tumbling machine, meat mixing machine, sausage machine, patty machine and smoking oven etc. let us enjoy the tender, tasty beef, beef steak, beef sausage or other beef products.
Beef muscle meat can be cut into roasts, short rib or steak or processed into corned beef, jerky, and other processed meats. Trimmings are ground for hamburger and meat patty; minced or used in sausages. Organ meat is consumed; blood is used in some varieties of blood sausage. Other parts that are eaten include oxtail, liver, tongue, tripe from the reticulum or rumen, glands, the heart, the brain, the kidneys. The intestines are used as sausage casings. The bones are used for making beef stock. The hide is used for leather.
hammer mill: components, operating principles, types, uses, adva
Hammer mill is the most widely used grinding mill and among the oldest. Hammer mills consist of a series of hammers (usually four or more) hinged on a central shaft and enclosed within a rigid metal case. It produces size reduction by impact.
The materials to be milled are struck by these rectangular pieces of hardened steel (ganged hammer) which rotates at high speed inside the chamber. These radically swinging hammers (from the rotating central shaft) move at a high angular velocity causing brittle fracture of the feed material.
The material is crushed or shattered by the repeated hammer impacts, collisions with the walls of the grinding chamber as well as particle-on-particles impacts. A screen is fitted at the bottom of the mill, which retains coarse materials while allowing the properly sized materials to pass as finished products.
The above subtype is based on the direction of the rotor (clockwise direction, anticlockwise directions or in both directions). Their working and grinding actions remain similar despite the fact that their construction differs in many respects.
a data-driven decision-making framework for online control of vertical roller mill - sciencedirect
An online control decision-making framework based on the running state data is proposed.The real-time rolling prediction and identification of VRM working condition based on time window are carried out.The generation of control strategy is studied based on the correlation of stability indexes.The real-time stability control strategy can be given for unstable working conditions.A real industrial application example is presented.
Vertical roller mill (VRM) is a large-scale grinding equipment, which is used to grind raw materials from block/granule into powder. Due to harsh production environment and inconsistent raw material quality, VRM requires timely regulation. Currently, the regulation of VRM is manually conducted; operators make decisions based on their observation and experience, therefore the timeliness and accuracy of regulation cannot be guaranteed. This study presents a data-driven online control decision-making approach; it extracts several key indicators for state judgment from the historical running state data, constructs a stable mode library based on clustering the running state, mines the association rules among variables, and establishes the rolling prediction model to predict the changes in the key indicators. In real-time operation, the target state is obtained by comparing the real-time state and stable mode library, and then the corresponding control strategy, composed of key indicators, controllable parameters and target state, is auto-generated to support the management of VRM operation. In this way, a closed-loop framework is formed based on offline data mining and online decision-making, supporting the operation optimization of VRM. This approach is applied in a cement plant as a case study in Jiangsu, China. The results show that the control strategy is effective in actual working conditions; the continuous operation of the equipment with vibration reduction is achieved.
