Trommel screen Wikipedia

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. It consists of a perforated cylindrical drum that is normally elevated at an angle at the feed end. Physical size separation is achieved as the feed material spirals down the rotating drum, where the undersized material

Crusher Wikipedia

Primarily used in-pit at the mine face these units are able to move with the large infeed machines (mainly shovels) to increase the tonnage produced. In a mobile road operation, these crushed rocks are directly combined with concrete and asphalt which are then deposited on to a road surface. This removes the need for hauling oversized material to a stationary crusher and then back to the road

Tube dryers are used successfully worldwide for the drying of raw lignite, hard lignite, hard coal, corn, cereals and other free-flowing materials. In the drying of lignite, the indirect drying (contact drying) in the tube dryer has been proven for many years for reasons of reliability and safety.

Aggregates Particle Testing Standards

Instructions are included for sieve analysis of such aggregates. 1.3 Units The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. Note 1

High pressure grinding rolls (HPGR) minevik

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
