Introduction to drum screen
Drum screening machine is a type of mineral processing equipment that classifies materials based on their particle size, also known as drum sand screening machine. Due to its simple process layout, it is widely used for product classification in industries such as mining, building materials, transportation, energy, and chemical engineering. Commonly used in the grading and screening of medium and fine-grained materials to improve material quality. Hongtong Machinery can professionally customize advanced drum screens of various models, specifications, and vibration modes according to the different actual situations of users.
According to the particle size of the screened material,type，The differences in output and customer requirements are divided into：Heavy duty drum screen,Standard typeTrommel（Single layer,Multi layer, single-layer, multi segment)Mobile drum screening integrated machine, mobile diesel power generation gold selection machineWait. Now 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.

Multi layer shaftless drum screening machine (also known as idler drum screening)

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, minimal maintenance, simple maintenance, easy replacement of screen mesh, and long service life of screen mesh. According to the user's needs, we can choose from single-layer drum screens (mainly separating two particle sizes), multi-layer drum screens, and single-layer multi-stage drum screens (which can separate materials of multiple particle sizes). Please contact our sales staff by phone to determine which one to use.

Mobile drum screening integrated machine
According to user needs, some customers have multiple screening locations and the screening amount is not very large. If they purchase fixed ones, they will need several sets. And made into a mobile screening belt conveyor, it can easily screen at different locations, greatly reducing investment costs.

Purpose of drum screening machine
The drum screen is mainly used for grading the particle size of materials and is widely used in production industries such as power, mining, metallurgy, building materials, and chemical industry. Commonly used for grading refractory materials, coal, sand and gravel, as well as screening sticky and wet materials such as coal, coke, white ash, and sand gold ore, to make the product structure more uniform and meet production needs. Can also be usedCircular vibrating sand screening machine

Working principle of drum screening machine

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. The qualified particle size material falls into their respective funnels after screening, and is then manually transported out or automatically transported to the finished product station through a conveyor. Qualified products are discharged through the lower discharge port, with larger particles. Unqualified products are discharged through another discharge port, and the cleaning device inside the cylinder is used to prevent the sieve from being blocked.

Structural characteristics of drum screening machine
The drum screen is mainly composed of drum device, reducer, motor, screen cleaning device, bottom bracket, sealing cover, discharge port, feed port, etc. The cylinder is placed at an angle and covered by a dust-proof sealing cover, which causes almost dust and noise pollution during the production process.

Performance characteristics of drum sand screening machine
The sieve holes are not easily clogged.
The drum screen runs smoothly with low noise.
The structure of the drum screen is simple and easy to maintain.
The 4 screening tubes can be sealed, making it easy to seal and collect dust.
The 5-roll cage screen has high reliability and requires less one-time investment.
6. Using a specially designed sieve, the screening efficiency is high and the service life is long.
