Compost trommel screen manufacturer in China

Composting trommel screen is a kind of sorting equipment widely used in pre-sorting and composting of urban mineralized waste. The screen cylinder of the traditional drum screen is supported by a roller. During operation, the two active rollers on the side of the cylinder are rotated by a motor, a reducer, etc., and the active roller drives the cylinder to rotate by the frictional force, while the other side The two roller wheels act as slaves. This trommel screen has low energy consumption.

How does the compost trommel work?

The screen surface is the working part of the screening machine and needs to be mounted on the frame and fixed by bolts and pressure plates. The screen body supports a left-right symmetric arrangement, a friction transmission, and a bilateral drive. The screen cylinder is supported on the driving wheel, and the motor rotates through the speed reducer to drive the screen cylinder. The transmission form of the trommel screen is divided into gear transmission, chain transmission, belt transmission and friction transmission according to the screen driving mode.

The inclination angle of the trommel screen affects the residence time of the garbage material in the sieve cylinder. It is generally considered that the inclination angle of the trommel sieve cylinder is within the range. The material to be sieved enters the cylinder from one end of the cylinder into the cylinder. Due to the rotation of the cylinder, the material slides along the inner wall of the cylinder, and the fine material smaller than the sieve mesh hole falls into the receiving tank, and the coarse material larger than the sieve hole is The other end of the cylinder is discharged.

The structure of compost drum screen

The structure of the sieve cylinder has a circular shape, a polygonal shape, and a composite shape. Usually, the circle is used because the balance of the circle is good, the operation is smooth, the processing is simple, and the balance between the polygon and the composite shape is poor, and the vibration of the motion is large. The screen cylinder is mainly composed of a sieve plate, a frame, and a guide plate. The sieve plate is formed by punching or drilling a mesh hole on a certain thickness of the steel plate and determining the thickness of the sieve plate according to the characteristics of the sieved material, the sieve plate needs to meet the requirements of high strength, uniform wear and long service life.

Maintenance and storage method of vibrating screen motor and common troubleshooting

The service life of the vibration motor determines the operating life of the entire screen. Therefore, in the normal production, we must always pay attention to whether the working state of the vibrating screen equipment is normal, whether the vibrating motor is in good working condition, timely check and solve some small abnormalities and faults, and do a good job of cleaning and maintenance, because this can greatly increase the vibration screening. Machine and vibration motor life. dewatering screens supplier Maintenance storage precautions during vibrating screen motor operation The equipment can not be completely dust-free, but also has a harsh environment and dusty conditions. The vibration motor is airless and heat-cooled. It relies on natural cooling, so it must be specially maintained. The following is the maintenance content. 1. It is necessary to pay attention to whether the vibration is abnormal during the use process; 2. Always check if the bolts used in the m

300t per hr chalcopyrite washing equipment

Chalcopyrite is a copper-iron sulfide mineral. It often contains trace amounts of gold and silver. Crystals are relatively rare and are tetrahedral-shaped, mostly irregular granular and dense massive aggregates, as well as kidney-shaped and grape-shaped aggregates. Copper yellow, often dark yellow or mottled. The streaks are black with a greenish tint. Chalcopyrite is a relatively common copper mineral, which can be formed in different environments, but it is mainly the product of hydrothermal action and contact metasomatism, and it can often form deposits of a certain scale. The origin is all over the world. In industry, it is the main raw material for copper smelting. In the field of gemology, it is rarely used alone, occasionally as a substitute for pyrite. In addition, it often participates in the composition of some colored stones, inkstones and jade. The high-efficiency spiral chalcopyrite washing machine is mainly used in the washing, grading, impurity removal, and the washing o
