How to screen unqualified composts out

Basic info

Organic fertilizer screening machine is often used in the production of compound fertilizer. It is mainly used for separation of finished products and counter materials. It realizes the classification of finished products, makes the classification of finished products even, and adopts the combined network, which is convenient for maintenance and replacement. This machine has a simple structure. The operation is simple and stable.

Working principle

According to the working principle, the vibration echo machine is divided into vibration echo machine and drum echo machine. It is widely used in coal preparation, mineral processing, building materials, water and electricity, light industry, construction, garbage classification and other crop raw materials dry separation, with large production capacity and high screening efficiency.

Vibration types

This paper mainly introduces the vibration screening machine. The vibrator with adjustable amplitude eccentric block structure is adopted in the machine, which has the characteristics of simple structure, convenient maintenance and long service life.

1. Generally, when the vibrating screen machine is transported out of the factory, the exciter is filled with lubricating oil, which has anti-corrosion performance and is valid for three months. When the storage period exceeds three months, it will run for 20 minutes and can be retained for another three months. It must be replaced with clean lubricating oil.

2. Always keep the exciter fan open (oil leakage due to blockage). If there is still oil leakage after dredging, the oil seal should be replaced.

3. The normal operation of the bearing should not exceed 75 ° C. Due to the operation process, the temperature of the new exciter may be slightly higher, but after 8 hours of operation, the temperature should be stable. If the temperature is still too high, check the oil, oil level and oil cleanliness.

4. Make sure the labyrinth water tank is filled with grease. If it works under a lot of dust, grease it more frequently.

5. When replacing the V-belt, the motor anchor bolt should be completely loosened, and the V-belt should be conveniently placed in the pulley groove. V-belts should not be used with the stick or other objects. The tension of the V-belt must be appropriate. After adjusting the tension for the first time, the belt must be aligned, work for 48 hours, and then adjust again.

6. The bolts connected to the shaker and screen box are high strength bolts. It is not allowed to replace them with ordinary bolts. Tightening must be checked regularly, at least once a month. If any one of the bolts is loose, the other bolts will be cut off and the screen will be damaged.

7. When ring groove rivets are used, it is allowed to replace them with high strength bolts. All contact surfaces or holes shall be free from iron image, ash, oil, rust and burr.

8. The high strength bolts, nuts and washers used must meet the requirements of "technical conditions for high strength large hexagon bolts, large hexagon nuts and steel structure washers". Go here for more details.
