The drum screen machine is suitable for screening materials of various properties and wet and easy-to-block materials such as coal, coke, lime, etc., gravel fields, and other industries, so it is also called a mining drum screen. The maximum size of the screened product is less than 100mm, the middle is 10-50mm, and the finest can reach ≤3mm.
Drum screening machine usage scenarios
1. Classification of various organic fertilizers, organic-inorganic compound mixtures, inorganic fertilizer particles, and impurity removal of powdered fertilizers, sawdust, and other materials.
2. Used for grading large and small stones in the stone field. And separate soil and stone powder;
3. Used for separation with sand and stone in the sand field;
4. Chemical industry, mineral processing industry for grading large and small blocks and separating powdered materials.
A drum screening machine is a commonly used equipment in compound fertilizer production. It is mainly used for the separation of finished products and return materials. It can also realize the grading of finished products and make the finished products evenly classified. The combined screen is easy to repair and replace. The machine has a simple structure, easy operation, and stable operation.
Introduction of drum screening machine
The drum screening machine is a new generation of self-cleaning screening equipment after electric vibrating screens and ordinary mesh drum screens produced by major domestic companies. It is widely used for the screening of various solid materials with particle sizes less than 300mm. It has many characteristics such as high screening efficiency, low noise, small dust, long service life, small maintenance, and convenient maintenance. Comprehensive utilization power stations (mainly circulating fluidized bed boilers) that mainly burn inferior coal are rapidly emerging. Fuels mainly based on coal ore usually have the characteristics of stickiness, wetness, dirtiness, and impurities. The coal transportation system generally has the problems of screening machine blockage, low screening efficiency, large wear of crusher, and high energy consumption. Cage drum screening machine, due to its unique structural characteristics, completely and effectively solves the shortcomings of other types of screening equipment and is a screening type for comprehensive utilization power stations.
The main structure of drum screening machine
The drum screening machine consists of a motor, reducer, drum device, frame, sealing cover, inlet and outlet, etc. The drum device is installed on the frame at an angle. The motor is connected to the drum device through a coupling via a reducer and drives the drum device to rotate around its axis.
Features of drum screening machine
1. High screening efficiency Because the equipment is equipped with a plate-type screening mechanism, during the screening process, no matter how sticky, wet, or mixed the material entering the separation screen is, the relative movement between the screening machine and the screen body will never block the screen, thereby improving the screening efficiency of the equipment.
2. Good working environment The entire screening mechanism is designed in a sealed dust cover, which eliminates the dust flying phenomenon during the screening process, thereby improving the working environment.
3. Low equipment noise When the equipment is in operation, the noise generated by the material and the rotating screen is completely isolated by the sealed dust cover, so that the noise cannot be transmitted to the outside of the equipment, thereby reducing the equipment noise.
4. Long service life The equipment screen is composed of several circular flat steels with a specification of 16mm×12mm. Its cross-sectional area is much larger than the cross-sectional area of the screen bars of other separation equipment screens, so the service life is improved.
5. Easy maintenance: There are equipment observation windows on both sides of the equipment’s sealed dust cover, so the staff can observe the equipment’s operation at any time during work. There are quick-open maintenance doors at the end of the sealing cover and the side of the cleaning machine mechanism, which is very convenient for regular maintenance of the equipment without affecting the normal operation of the equipment.
