How to slove the wear of the impeller?

 




The materials in the sand washing machine have been crushed in various ways from granular to powdery with different meshes: the lining plate mainly accepts the force of the impeller, and the wear mode is mainly the conflict between each other, so the surface Both hardness and toughness have certain requirements; the guard plate is mainly due to the friction and wear of material activities, and the demand for impact is not high; all accessories are also subject to corrosion and wear. The impeller exists in the movement of the fine sand recovery machine, and the parabola formed by the falling down crushes the material; the conflict between the impeller and the material, the material and the material, the material and the liner; the mutual crushing caused by the free fall of the material.


It can be seen from this that there are many ways of wearing the wearing parts in the sand washing machine. The impeller is mainly caused by falling and friction wear, so there is also a demand for out-of-roundness of the impeller in addition to wear resistance; Different needs do not necessarily require the same raw materials. Appropriate materials should be selected according to different operating conditions to achieve economical and practical purposes under the premise of meeting the needs.

Slove method of the clogging of trommel screen sieve

The drum screen is a simple screening device.  The trommel screen  is easy to close and collect dust, the maintenance is small, the maintenance is simple, and the service life is long. It is a device frequently used in refractory materials, coal, river sand classification, and sandstone classification. The advantage of the trommel screen is that the structure is not complicated so that the device can be quickly operated, and when the trommel has problems, people can easily solve it. But what should I do when the screen of the trommel screen is blocked? The following screen will introduce several ways to solve the phenomenon of blocking the net. The trommel screen sometimes adopts a mechanism added to the fixed frame, and then the mechanism rotates to drive the belt mounted on the belt to continuously smear the surface of the sieve hole, thereby sucking out the raw material particles blocked in the sieve hole. One of the disadvantages in practice is that it produces a lot ...

Several types of flocculation tanks

The concentrator is a continuous working concentration and clarification equipment. It is mainly used for dehydration of fine and tailings pulp in wet beneficiation operations. It is also widely used in the concentration of solid slurry in coal, steel, chemical, building materials, water sources and sewage treatment. And purification. The ordinary concentrator works reliably, has low operating costs, and can store and buffer the feedstock. However, it is based on the gravity sedimentation of the particles. The sedimentation velocity is proportional to the square of the particle diameter, which is used to treat the microparticles and has low efficiency. The high-efficiency concentrating machine mainly uses the reasonable use of flocculant and the cloth feeding method at the bottom to increase the sedimentation speed, which is one of the most important progress in the concentration technology. Different type of flocculation tanks Thickener tanks , Deep Cone Thickener, Sludge Thi...

How to desilting municipal drains and canals?

The river channel sludge filter press is a special equipment, which is used to deal with river channel dredging sludge, lake sludge and sludge brought ashore by cutter suction boats. The equipment adopts the principle of automatic water removal and extrusion dehydration. First, the sludge is introduced into the equipment through a slurry pump, and after pressing and squeezing, the output is clear water and mud cake. This treatment method does not require manual unloading, and the moisture in the mud cake is effectively removed, which can be directly packaged and transported, and the clean water produced can be directly discharged. Automatic processing: The equipment adopts an automatic control system to realize automatic water removal and extrusion dehydration without manual operation, which greatly saves labor costs and time.
