waste recycling system, trommel screen supplier, factory
The rotating trommels are installedupstream of installations of selection municipal solid waste and maintain the screening of MSW exploiting the different size from they possess. They have the function of separating the feed stream into two streams. The separation of the individual parts placed in a current of fall, properly fed, takes place according to the different particle sizes.
In this phase, trommel screen is to sort the waste by hole size of the long drum. Different sizes of the holes are sorting the materials of different types (less than 80mm for Inerts like sand, broken glass, ceramic and stone, 80mm to 200mm for recyclable plastics and 200mm to 300mm for paper and big plastics.). The individual parts behave separately parts having sizes lower than the diameter of the holes of the network sieving fall to the bottom of the machine, the parts having size greater than the diameter of theholes network sieving advancing upwards of the machine, following the rotational movement, in the direction of exit and fall into the discharge hopper arranged to the surroundings great.
ez-409: compact trommel screener by ez-screen
The constant tumbling action stirs up material over and over, fluffing it, adding air to lighten it, and keeping it in contact with the rotating mesh longer. This action allows more material through faster and easier. Which makes the trommel the screener for landscapers, excavating contractors and municipalities.
So what makes the EZ-409 the better choice over other trommel screeners? One big reason is the small price. The price is low because we sell direct, one to one. No sales force. No inventory. No showrooms. No commissions.
Another reason is a whole lot of reasons: like a baked on powder-coat finish; vulcanized conveyor belts; a durable 50-HP Deutz diesel engine; auxiliary hydraulics for adding another stockpiling conveyor; and hydraulic jacks at the discharge end for proper tilt angle to adjust the material flow speed.
Like all EZ-Screen machines, the EZ-409 is easily trucked from job site to job site. Set up is quick, too. Working with a to 1 loader, the EZ-409 is designed, engineered and manufactured to provide outstanding production for specialized screening operations. With its chain-driven heavy-duty rotating drum, the slipping that occurs in wet materials on wheel-driven competitive trommel screeners is eliminated.

what is trommel screen and how does trommel screen work | m&c
Trommel screen, or rotary screen, is a kind of mechanical screening machine which is widely used in the separation operation. It controls the material separation by the particle size, and the separation precision is high. The cylinder of the trommel screen is generally divided into several sections, depending on the specific situation. The mesh holes are arranged from small to large, and the mesh hole diameter on each section is the same.
When the material enters the drum screen, due to the inclination and rotation of the roller device, the material on the screen surface will turn over and roll, so that the qualified material will be discharged through the outlet at the bottom of the drum, and the unqualified material will be discharged through the outlet at the end of drum.
1. It is used for sand screening in sand plant; 2. Used as sand screening machine to screen sand and stone; 3. Used as gold washing equipment for screening and cleaning sand, stone and gold; 4. Used for screening mineral materials in gold boat.

trommel screens | multotec
Through our worldwide network of branches, our trommel screening specialists supply complete turnkey trommel solutions tailored to your specific process and plant requirements, from engineering and design, through to installation, commissioning, field service and the supply of trommel spares, including screen panels.
Multotecs ongoing research and development and focus on continuous equipment optimisation has resulted in rotary trommel screens that are engineered for maximum impact and abrasion resistance to deliver enhanced screening life that optimises your process efficiency.
Our heavy duty trommel screens consist of the rubber-lined steel frame and replaceable screening surface. Several modifications can be made to this basic trommel screener, including a dual media screen to produce a two-fraction material grading.
When a client requires a new trommel screen, our first step is to determine the main process parameters of your application. There may be a lot of variation in the diameter of the bolt on flange diameter, for example, as it depends on the size of the mill.
The feed end flange is designed to be compatible with the mill or scrubber flange. The flange has a machined face with a compatible bolting arrangement to the mill / scrubber discharge trunnion flange.
The internal diameter of the feed-end flange or feed-end liners is designed to be the same diameter as the mill discharge or mill discharge liners. The trommel feed end liners can also have a slightly larger diameter to create an outwards step to compensate for wear of the mill discharge liners.
Using Finite Element Analysis (FEA) across the complete trommel screen design allows Multotec to calculate the stresses in the structure for a full rotation in order to optimise the fatigue life. The design process adheres to BS 7608:1993 for Fatigue Design Assessment of Steel Structures. Self-driven trommels are also designed by means of FEA and can also be supplied with a feed and discharge arrangement in accordance with specific customer requirements.
FEA is also used to calculate your unique requirement for special cross bracing to counter torsional twisting and account for the ongoing stress placed on the trommel by continuously shifting material loads.
Installed at the end of grinding mills and scrubbers, trommel screening is an efficient, mechanically robust method of screening coarse particles, with a trommel screen machine delivering excellent performance over a long service life.
Trommel screens provide a lower capital cost alternative to vibrating screens, and generate significantly less noise in your plant. Decades of global experience and innovation by world-leading metallurgists and mineral processing engineers at Multotec has allowed an optimum trommel screen design that reduces pegging and blinding and enhances your screening performance.
Our modular polyurethane or rubber panels allow only worn screen panels to be individually replaced, not the whole system. Our unique pins and sleeves or bolt down fastening systems simplify any maintenance requirements.
Multotec provides full engineering support and aftersales services for your screening plant. With preventative maintenance geared towards enhancing longevity of your trommel system, we can completely refurbish worn trommel screens to give them a far greater service life, and reduce capital requirements for your plant.
This includes stripping the rubber lining from the steel structure, prior to visual inspection for wear and non-destructive testing, carried out to determine the integrity of the trommel structure. If your screen is still within specification it can be shot-blasted and re-lined with rubber.
As leading trommel screen manufacturers, Multotec helps customers build larger trommel systems, by overcoming the high wear rates caused by higher peripheral speeds, heavier volumes, and increased flow rates and velocities.
rotary trommels | mclanahan
McLanahan manufacturing techniques guarantee that Rotary Trommel Screens are simple to operate. The design is also intended to be safer for operators. Specially designed safety features include sectionalized cylinder covers with inspection doors, an optional mast system to remove screen panels, optional inching drives, and a cylinder jacking and brake system for maintenance periods.
To serve many industries and applications, McLanahan Rotary Trommel Screens are offered with various types of screen media that have a variety of aperture sizes depending on the application requirement. For units that are larger than 10' (3m) in diameter, McLanahan performs a finite element analysis of a unit prior to manufacturing to ensure the optimal design strength.
As the cylindrical drum of a Rotary Trommel Screen rotates, raw feed material is lifted on shelves until it nears the top of the drum. Material then falls, tumbling onto other material at the bottom of the drum. This action helps to break down softer fractions, as well as separate different types of materials. As the tumbling continues, smaller size fractions filter through holes in the screen plating, while larger material continues along the length of the cylinder to discharge at the end.
The tumbling action of the Rotary Trommel allows accurate sizing and separation that is beneficial for a variety of customers, including those looking to upgrade metallics after mass-burn solid waste incineration, to reclaim wood chips in sewage sludge composting, for accurate size separation of difficult-to-screen materials in municipal solids waste and resource recovery, and to separate and wash ores, rock and other fine materials.
You should know your feed material bulk density, the material particle size feed distribution, the tons per hour feed solids capacity, a process flow diagram showing equipment location of required unit in your processing plant, the separation or cut point(s) and the moisture content.
Proficient in both wet and dry applications, McLanahan Rotary Trommel Screens utilize a continuous tumbling action to size and separate feed material in the municipal waste, industrial and mining industries. McLanahan Rotary Trommel Screens are manufactured to be perfectly concentric machines that produce the material you need for many industries and applications.

size separation of particulates in a trommel screen system - sciencedirect
This paper describes the design and testing of a trommel screen system for the separation of undersized particulates. The trommel screen system consisted of a cylindrical separation device that rotated to perform size separation. A series of experiments were carried out at room temperature to demonstrate the screening efficiency of this method under different operating conditions. The dynamic model and velocity analysis of undersized particulates in the trommel body are also discussed. The experimental results show that the screening efficiency could be enhanced by using a mass flow rate of 360cm/s, a dust concentration of 10,000ppmw, an inclination angle of the trommel body of 5 and a rotational speed of the trommel body of 43rpm. Moreover, the results also indicate that this type of method could be useful for dust particulate separation in a moving granular bed filter system. The main focus of the current study is the development of a trommel screen system for a moving granular bed filter that could be applied in a high-temperature environment.
