Gold Trommel Screen

Name:gold trommel wash plant trommel drum screen.

Trommel screen how to work:Material feeds into the drum, mateiral is lifted up by the rotation as it falls back down. This action is repeated with each revolution along the length of the drum. The finer material passes through the screen openings while the larger material tumbles towards its eventual exit at the rear of the drum.

Application:Trommel screen for wash and screening alluival gold/Placer gold,Tin,chrome,tantalum niobium,and sand plant!

Capacity:10-200tph

A trommel screen, aslo called rotary screen,Trommel is a mechanical screen machine for screening different size materials, Usually used for mining plant and sand plant. It consists of hopper,drum,frame,screen parts.material from hopper flow to drum by gravity,rotation the drum,material rotation in the drum,through the screen,less than screen size material through hole as unersize material,bigger than screen size material will on screen,and will rotation to the end drum as oversize material.normally,undersize material will to next separator machine such as jig machine,sluice box,centrifugal concentrator etc.oversize material will to crushing,or threw away through belt conveyor.

Trommel screens can be used in a variety of applications such as classification of solid waste and recovery of valuable minerals from raw materials. Trommels come in many designs such as concentric screens, series or parallel arrangement and each component has a few configurations. However depending on the application required, trommels have several advantages and limitations over other screening processes such as vibrating screens, grizzly screens, roller screens, curved screens and gyratory screen separators.

Some of the main governing equations for a trommel screen include the screening rate, screening efficiency and residence time of particles in the screen. These equations could be applied in the rough calculation done in initial phases of a design process. However, design is largely based on heuristics. Therefore, design rules are often used in place of the governing equations in the design of a trommel screen. When designing a trommel screen, the main factors affecting the screening efficiency and production rate are the rotational velocity of the drum, mass flow rate of feed particles, size of the drum, and inclination of trommel screen. Depending on desired application of trommel screen, a balance has to be made between the screening efficiency and production rate.
