A trommel screen, also known as a rotary screen, is a mechanical screening machine used to separate materials, mainly in the mineral and solid-waste processing industries. [1] It consists of a perforated cylindrical drum that is normally elevated at an angle at the feed end. [ 2 ]
Oliver-type rotary vacuum-drum filter. A Rotary Vacuum Filter Drum consists of a cylindrical filter membrane that is partly sub-merged in a slurry to be filtered. The inside of the drum is held lower than the ambient pressure. As the drum rotates through the slurry, the liquid is sucked through the membrane, leaving solids to cake on the ...
High-frequency vibrating screens are the most important screening machines primarily utilised in the mineral processing industry. They are used to separate feeds containing solid and crushed ores down to less than 200 μm in size, and are applicable to both perfectly wetted and dried feed.
Mechanical screening, often just called screening, is the practice of taking granulated or crushed ore material and separating it into multiple grades by particle size.. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.
Rotary cooler. A sectional cooler is a type of liquid cooled rotary drum cooler used for continuous processes in chemical engineering. [1] Sectional coolers consist of a rotating cylinder ("drum" or "shell"), a drive unit and a support structure. At each end of the drum there are stationary chutes for material feed and outlet
