Drum screen

Product introduction: The drum screen is used for grading and screening of medium and fine materials. It can be used for grading large and small stones in stone yards, and for separating soil and stone powder on the outside of the stones. It can be used for mutual separation and screening of sand and stones in sand and stone yards. In the chemical and coal industries, the drum screen is used for screening block and powder materials. It has a wide range of applications and low working environment requirements. Different models and specifications of drum screen equipment can be customized according to different material requirements to meet different production needs.

Tonghui Machinery can professionally customize various models, specifications, and vibration modes of drum screens according to different actual situations of users

Classification of drum screens

According to the particle size, type, output, and customer requirements of the screened materials, drum screens are divided into heavy-duty drum screens, standard drum screens (single-layer, multi-layer, single-layer multi-stage), mobile drum screening integrated machines, mobile diesel power generation gold selection machines, etc. Let's introduce them one by one.

Introduction to Heavy duty Drum Screen

The heavy-duty shaftless drum screen is mainly used in river sand screening, pebble sand screening, sand and gravel production lines, gold selection production lines, coal and coke industries, etc. It is an ideal substitute for traditional circular vibrating screens, with the characteristics of no vibration power, no noise, and no need for a large amount of infrastructure construction. The equipment has the advantages of simple structure, low maintenance and daily maintenance, and can be integrated with single or multiple layers, achieving the purpose of one machine for multiple uses and greatly saving procurement costs.

Introduction to standard drum screen

The standard drum screen is mainly used for screening refractory materials, coal powder, river sand, non-ferrous metals, etc. It has the advantages of closed dust collection, low maintenance cost, simple maintenance, convenient replacement of screen mesh, and long service life of screen mesh. According to user needs, single-layer drum screen (mainly separates two particle sizes), multi-layer drum screen, and single-layer multi-stage drum screen (can separate materials of multiple particle sizes) can be selected. For specific use, please contact our sales staff by phone.

Introduction to mobile drum screening integrated machine

According to user needs, some customers have multiple screening locations and the screening capacity is not very large. If they purchase a fixed one, they need several sets. However, by making it a mobile screening belt conveyor, it is very convenient to screen at different locations, greatly reducing investment costs.

Structure and working principle of drum screen

The drum screen mainly consists of a motor, a reducer, a drum device, a frame, a sealing cover, and an inlet and outlet.

The motor drives the drum axis to rotate, and the reducer adjusts the drum body to rotate at a certain speed. The material enters the drum body through the feeding port, and under the centrifugal force generated by rotation, the material rolls inside the drum and is separated from top to bottom through the grading screen. Due to the different grading sizes of the screen, the material is gradually separated and screened. Materials with qualified particle size are sieved and fall into their respective funnels, and then manually transported out or automatically transported to the finished product station through the conveyor. Qualified products are discharged through the lower discharge port, with larger particles, and products with unqualified sorting are discharged through another discharge port. The cleaning device inside the drum prevents the screen from being blocked.
