Trommel Screen

The 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.
LZZG trommel screens are designed to minimize setup time and be easy and convenient to service.We have perfected the ability to size and customise trommel screens with different materials to suit the application,such as the updated product compact sand washer.

LZZG series introduced products to absorb foreign advanced technology, and designed combined with sand field actual situation. It can effectively reduce the loss amounts of fine material; solve problems of end product such as relatively high fineness modulus and relatively low stone powder content. The fine material can be recycled as high as 95%, with incomparable technical and economic advantages.

Details Introduction

The trommel screen is a screen that is curved into a cylinder. These trommel screens are also referred to as trommel drums or drum screeners. They are usually used to separate different grades of material such as soil, gravel, mulch, and sand by size. The trommel screen mainly consists of motor, reducer, drum device, frame, sealing cover and inlet and outlet.

Working principle
When trommel screens working, raw feed materials are picked up by the drum screens until it near drum top. Material then falls back down to the bottom of the drum by gravity. As it tumbles, the softer fractions broken down. The process repeat, smaller size materials pass throuth the screens while the larger size material pass through the opposite end outlet of the trommel drum, achieve accurate sizing and separation.

Features
1. Adopting rolling conveying, the friction coefficient is small, and the sieve hole is not easy to clog.
2. The drum support adopts integral through-shaft structure, which runs smoothly, does not vibrate and has low noise.
3. The internal drum screen fittings are designed separately, which is simple in structure and convenient in replacement and maintenance.
4. The drum body adopts an effective fully sealed structure, without dust and pollution.
5. Safe and reliable operation, adopting deceleration drive, high transmission efficiency.
6. Customized screen, high screening efficiency, long service life and low maintenance cost.
7.Equipped with sprayer, proficient in both wet and dry applications.
