Dewatering screen failure quick elimination method



High frequency dewatering screen cannot be started or the amplitude is too small

Should first consider whether the motor is damaged, or whether the components in the line are damaged, or the local voltage is insufficient at the time. If there is no problem in these three aspects, then it should be checked from the machine, and the material on the screen surface should be piled up too much. Clear it immediately. Since the accumulation of too much material directly affects the amplitude of the vibrating screen. Whether the coupling bolt on the vibration exciter is detached or not, and the grease is thickened and agglomerated. At this time, the exciter can be cleaned and the eccentric shaft weighting block or the position of the sub eccentric block can be appropriately adjusted.

Abnormal material activity on the screen

It may be that there is an insufficient critical frequency of the screen box, indicating that the coupling bolt has been loosened, and even the degree of full vibration needs to be tightened immediately. Second, the horizontal level of the screen box is not fixed, and the fault is detected from the support foot spring itself. The spring or the size of the pad or the seat can be changed, and the screen mesh may be damaged. Just replace the screen. If the rigidity of the screen box is insufficient, the horizontal level will not cause the beam to break. If it is still running, the material will be abnormal. It is also possible that mishandling, that is, the extreme imbalance of the feedstock is also one of the reasons.

The vibrating screen rotates slowly and the bearing heats up.


This shows that the usual maintenance has not kept up, the bearing lacks grease; daily maintenance is also very important. If the bearing is a new grease, it may be the quality of the grease or too full, the inferior oil makes the bearing obstruction maze seal jam, so the quality of the grease is important. The quality of the vibrating screen is not good. The reason is that improper use may also be blocked by the mesh. The fine particles in the feed material increase and the moisture increases, so that the upper layer of the screen is too thick and the feeding is uneven. The responsibility on the machine may be screen. The two sides are not pulled tightly. If the shaft is eccentrically vibrated, the belt may be too loose in the belt drag.



The drum screen belongs to the relatively large processing equipment in the screening equipment. Although there is no complicated structure of the magnetic separator and the sorting machine, the processing amount is large during the use, so it is inevitable that some mechanical equipment will appear during the long-term use. The failure of the technical experts gives the corresponding solution.

1. Noise problem caused by loose equipment bolts Solution: Retighten bolts or other fasteners;
2. Wrong direction of rotation caused by wrong connection of motor power cables Solution: Replace the power cable in the junction box;
3. Solution to the clogging of the sieve of the trommel screen

The characters of Dense Medium Cyclone

  Features Of DMC 1. The separation efficiency of the heavy medium cyclone is relatively higher than that of the ordinary hydrocyclone, which is also one of the important factors that people like to use it. 2. The adjustment range of the separation density of the heavy medium cyclone is relatively wide: the separation density of the heavy medium coal separation is generally 1300 kg/m3 ~ 2200 kg/m3 and it is also convenient to adjust this is its advantage. 3. The heavy-medium cyclone has a relatively strong use capacity and not only has a wide range of sorting strength, but also has a good effect on the quantity and quality of coal preparation. 4. The sorting particle size range is wide. The size limit of the lump coal separator is generally 100-6mm, and the particle size limit of the fine coal heavy medium cyclone is 50-0mm (the sorting depth can reach 0.15mm). 5. The heavy medium cyclone has large processing capacity, the current maximum processing capacity of the heavy medium separat

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

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
