complete grain processing line and flour milling plant for 10-500tpd project
AGICO is a world leading professional grain processing line manufacturer that provides turnkey project design, installation and commissioning. We mainly engage in 10-1000ton/d wheat flour mill plant, 10-200ton/d maize/corn flour mill plant, and other grain processing machines.We specialize in supply the technology and service on single flour milling machine, small flour milling machinery from 10TPD to 30TPD and complete set of flour mill 40-500TPD for wheat, corn and cereals etc. Depend on the support of many different factories, we can supply the different designs with different cost to meet different buyers request for grain processing line. If your business is simple and initial investment is limited, 40-60TPD flour mill plant is right for you, it is steel frame construction, low cost. But if you intend to large scale supply of flour, you would have to take care of 80-250TPD or 300-500TPD complete flour mill plant. It occupies larger land spaces to build the plant workshop.
We also supply all the flour mill machines which can be used in complete grain processing line, like grain cleaning plant, grain hulling plant and flour milling plant. With more than 20 years of production experience in grain processing line, AGICO has built many turnkey projects for our clients in New Zealand, Chile, Zambia, Argentina, Indonesia, Ethiopia, Colombia, etc.
Grainmilling is the process of turning grain such as wheat, corn and other kinds of cereals into flour. Find out this knowledge could help you start a business of grain processing line. AGICO is well recognized worldwide turn-key project design provider, especially for wheat milling, corn milling. We are capable of A to Z engineering services from consultancy, design, manufacturing, onsite installation, staff training, repair and maintenance and business extension ideas.
solving problems on the tube mill
1. No written procedures for setup. Every mill should have written procedures for all operators to follow. The machine, tooling, and steel are fixed factors in the mill setup equation; the only variable is the human factor. This is why it is so important to have written procedures in place to control the process. Written procedures also provide a tool for troubleshooting when problems arise.
4. Disregard of parameters from previous setup. If the tube mill has been set up according to the written procedures and setup chart, the operator can write down the numbers from the digital readout on the single-point adjustment (SPA) unit, allowing the next operator to set up where the first left off. Setting up to the numbers can save as much as 75 percent of total setup time, as long as all the other tips discussed in this article are followed.
5. Mill in poor condition. A poorly maintained mill costs valuable time and scrap during setup and operation. The mill must be dependable so that the operator is not chasing mechanical problems during normal operation and setup. A good maintenance program, as well as rebuilds or upgrades when necessary, is essential.
7. Tooling in poor condition. Operators must know how much life is left in the tooling before the next scheduled rework. Running the tooling until it cannot produce tubing anymore not only wastes valuable mill time, but produces scrap and affects delivery schedules. All tube production companies should have a tooling maintenance program in place.
Any of these causes of lost time on the mill can have varying degrees of value, depending on the severity of the conditions. The bottom line is, the more of these items that are in control, the less downtime on the mill.
When irregular size occurs in the sizing section, the problem may not necessarily be in the sizing section itself. The operator also must check the setup in the breakdown, fin, and welding section of the mill to ensure proper presentation to the sizing section. If the forming section sends improperly formed tube to the sizing section, irregular tube size can result.
Weld chatter is the inability to achieve a clean cut of the outside weld bead after welding. The scarf knife chatters and produces a ribbed or rough cut on the OD of the tube. This is unacceptable in most of the end products produced by the tube and pipe industry.
An ironing pass should be used after the scarf stand. As the name implies, this stand irons out any hot imperfections the scarf knife may leave behind. It also adds a tremendous amount of stability to the scarfing operation.
On mills that employ induction welding, moving the induction coil upstream a bit and away from the weld rolls helps temper the edges of the strip by preheating them before welding. This results in a more malleable material that is softer and easier for the scarf knife to cut.
The heel of the scarf knife or insert should be ground to an angle of 18 degrees from the horizontal, and the tool should be set at an angle of 15 degrees from the vertical. This provides the proper clearance so the knife does not drag on the tube or pipe. A straight up-and-down approach to the tube or pipe invites chatter.
In general, several tube mill areas should be checked on a regular basis. This should be done at least monthly, but should be based on the usage. A higher production rate or running heavier metals through the mill requires more frequent checks. Shafts should be checked for OD, looseness, bending, and parallelism. Shoulder alignment should be checked, and the integrity of the entry table, drive stands, side roll boxes, weld box, and Turk's head units should be ensured. Of course, rolls should be checked to ensure they have been installed on the correct stands.
Once a year, the mill should be aligned. A mill alignment usually takes one or two days and is most often done by a professional. Every day, the mill operator should use a setup chart and follow all operating procedures.
tube mill machine | rolling mill machine | lotos 2020
Tube Mill Machine | Rolling mill machine | LOTOS 2O19 is a new welding technology, which coats thin stainless steel on the surface of carbon steel pipe with high strength, the product has the features of both artistic appearance, therefore, corrosion resistance of stainless steel and high strength of carbon steel. It is the best substitute for stainless steel pipe as its lower price compared with that of welded steel pipe.
Choose us, you do not only get the tube Mill Line from us, but you also get technology from us. We select the best welding method for customers from high-frequency welding, TIG welding, plasma welding, and laser welding depending on the usage, welding requirements, and production efficiency.
The tube mill is widely used in household commodities, shoe racks, public facilities, and guardrails such as all kinds of clothes racks, retractable poles, article racks, all-purpose combination racks, table, and chair legs, indoor handrails, ship and bus racks, and outdoor guardrails.
Firstly, the stainless steel strips are made to go through various quality checks and are trimmed at the edges. The strips pass through the number of rollers as per the required size. In the tube mill, the strip is gradually converted into a tubular shape. The fitted welding machine is then used to weld trim edges of the strip welding process. In this way, rolled pipes and tubes are formed.
The rolled stainless steel pipes thus manufactured are cut to the required lengths depending upon the industrial demand. These stainless pipes and tubes are then subjected to cleaning to remove the dirt. Further, a heat treatment is given to these rolled pipes and tubes to remove the stresses that may occur due to welding and formation processes. Heat treatment is given on the continuously rolling hearth furnace. The furnace is fitted with temperature recorders and controllers. After the heat treatment process, the stainless steel tubes and pipes are straightened and subjected to pickling for removing scales from the surface.
In some cases, the required size may not be obtained from the mill directly. Then, the cold operation process can be used to obtain the desired size. In the cold drawing process, the tubes or pipes are coated with oxalic and soap solution. This solution acts as a lubricant to reduce friction while cold drawing operation.
The drawn-out tube or stainless steel pipe is then subjected to cleaning, heat treatment, pickling, and straightening. The computerized inkjet marking machine is used to do the marking on the finished pipes or tubes.
