Wood chip filtering machine, sawdust rotary drum screen, wood powder cylindrical screening machine

The roller screen is a kind of machinery widely used in the separation technology, which can control the separation of garbage by the particle size, and the separation accuracy is high. The cylinder of the drum screen is generally divided into several sections, depending on the specific situation, and the sieve is arranged from small to large, and the screen aperture on each section is the same.

The drum screen is mainly composed of motor, reducer, drum device, frame, sealing cover and inlet and outlet.

The drum device is mounted on the rack at an Angle. The motor is connected with the drum device by the reducer through a coupling, and the drum device is driven to rotate around its axis. When the material enters the drum device, due to the tilt and rotation of the drum device, the material on the screen surface is turned over and rolled, so that the qualified material (under the screen product) is discharged through the bottom of the drum at the back end of the discharge port, and the unqualified material (on the screen product) is discharged through the discharge port at the tail of the drum. Due to the material turning and rolling in the drum, the material stuck in the screen can be ejected to prevent the screen plugging. The principle structure of drum sand screening machine, drum screen machine and drum screen is almost the same, which is the difference in people’s understanding and name.

Features

The drum device is mounted on the rack at an Angle. The motor is connected with the drum device by the reducer through a coupling, and the drum device is driven to rotate around its axis. When the material enters the drum device, due to the tilt and rotation of the drum device, the material on the screen surface is turned over and rolled, so that the qualified material (under the screen product) is discharged through the bottom of the drum at the back end of the discharge port, and the unqualified material (on the screen product) is discharged through the discharge port at the tail of the drum. Due to the material turning and rolling in the drum, the material stuck in the screen can be ejected to prevent the screen plugging. The principle structure of drum sand screening machine, drum screen machine and drum screen is almost the same, which is the difference in people’s understanding and name.

Scope of application

1. The stone yard is used for classifying large and small stones and separating soil and stone powder.

2. Used for sand and stone separation in the sand and stone field.

3, The coal industry is used for the separation of lump coal and coal powder and coal washing (a part of coal washing machinery).

4. Chemical industry and mineral processing industry are used for classifying large and small chunks and separating powdery substances.

The cage drum screen has reliable operation and small maintenance. Several problems that should be paid attention to in the following operation are summarized as follows:

1, Driving must first open the cage drum screen, and then open the feeding equipment; Reverse when parking;

2, Three days before the operation, to check the cage drum screen fasteners every day, if loose should be tightened in time. After that, the cage drum screen fasteners can be inspected and treated regularly (weekly or half a month);

3, Bearing seat, gearbox should be regularly checked lubrication, and timely refueling and oil change. Large shaft bearing using No. 2 lithium grease, under normal circumstances, every two months to fill the grease, the amount of filling should not be too much, otherwise easy to cause the bearing overheating. All bearings should be cleaned and inspected once a year.

4. When the equipment is out of service for a long time (more than 30 days), the motor insulation should be shaken to avoid the motor burning.
