In order for the industrial slurry pump to fully play its role, we need to understand the working principle of the industrial slurry pump: https://www.lzzgmachine.com/products/supporting-equipment/slurry-pump.html Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy to leave the outer edge of the impeller at a high speed and enter the volute pump shell. In the volute pump case, the Fluid is slowed down due to the gradual expansion of the flow channel, and part of the kinetic energy is converted into static pressure energy. At last, it flows into the discharge pipe and is sent to the place where it is needed. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed in the center of the impeller. Above the liquid level of the storage tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. LZZG slurry pump pe...

For many users who use dewatering screens , the quality of the sieve plates is very important, because the quality of the sieve plates directly affects the production volume, which reduces the economic benefits. Although it has been said that if the sieve plates are seriously damaged, replace them with a new one. However, after all, replacing the sieve plate is a very troublesome and unnecessary thing, so no one wants to continue to do so. However, in recent years, a new dewatering sieve plate appeared in the mining equipment parts market, called polyurethane dewatering sieve plate. The sieve plate of the dewatering sieve is related to the screening effect and the dewatering effect, so the importance is self-evident, so it is necessary to choose the quality when purchasing the dewatering sieve. 1. The customer asks: How long is the service life of the sieve plate of the polyurethane dewatering sieve? How can I reduce the frequency of sieve plate replacement? Under normal circum...

How does trommel screen work? The trommel screen is connected by the motor through the reducer and the roller device through the coupling and drives the roller device to rotate about its axis. Through the variable speed deceleration system, the screening cylinder is rotated at a certain rotation speed, and the material is separated from the top to the bottom through the screening cylinder, the fine material is discharged from the lower part of the front end of the drum screen, and the coarse material is discharged from the lower end of the screening cylinder.

The vibrating screen bearing works under heavy load and large centrifugal force, so the heating phenomenon is usually obvious. Normally, the vibrating screen empty car test 4h, the bearing temperature should be maintained at 35 ~ 60 ° C. If the bearing temperature is high, it may be caused by the following reasons. (1) Unreasonable bearing model selection If the vibrating screen is used frequently, the bearings in the exciter are frequently overheated and there is no obvious improvement after refueling. It is very likely that the bearing model is unreasonable. The main reason for this is that the bearing radial clearance is too small. The bearing on the vibrating screen has a high operating frequency and a very large load carrying capacity. At the same time, the load is a variable load. If the radial clearance of the bearing is too small, there is no way to withstand high frequency and large loads, so it is necessary to select a large clearance bearing when selecting. (2) lack...

When the filter cake needs to be washed, there are clear flow one-way washing and two-way washing, dark flow one-way washing and two-way washing. A. The clear flow one-way washing is that the washing liquid enters sequentially from the washing liquid inlet hole of the thrust plate, passes through the filter cloth and then passes through the filter cake, and flows out from the non-porous filter plate, at which time the liquid discharging nozzle of the orifice plate is closed. In the state, the outlet nozzle of the non-porous plate is open. B. The clear flow two-way washing is that the washing liquid is washed twice from the washing liquid inlet holes on both sides above the thrust plate, that is, the washing liquid is washed from one side and then from the other side, and the outlet of the washing liquid is the same as the inlet. The direction of the corner, so it is called two-way cross washing. C. The dark flow unidirectional flow is that the washing liquid enters the perfor...

The hydraulic desilter has a mud  cyclone desander , which first pumps the mud into a funnel container by a sand pump. The pumping direction is directed along the tangential line to the inner wall of the container. The slurry is rotated by centrifugation, the structure is destroyed, the cuttings and sand are discharged from the funnel, and the mud flows out from the upper opening of the container. The mud cyclone desander has better sand removal effect than the vibrating screen and is widely used in deep well drilling. hydro-cyclones The cyclone desander is based on the principle of centrifugal sedimentation and density difference. When the water flows from the sand removal inlet to the equipment in a tangential direction under a certain pressure, a strong rotary motion is generated. Due to the different density of sand and water, the centrifugal force, Under the combined action of centripetal force, buoyancy and fluid drag, the low-density water is lifted and discharged...

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.

In the sand washing production line , the ore dressing operation is very important. With the increase in environmental protection in recent years and the tight supply situation of domestic mineral resources, we have to use the tailings that were once overlooked. The tailings are ignored because the residue cannot be further sorted. However, with the development in recent years, we have found that tailings are not completely useless waste, and often contain other ingredients that can be used for other purposes. The processing technology and development and utilization can effectively “turn waste into treasure”, which not only eases the resources and environmental pressure but also realizes the comprehensive utilization of tailings! The tailings zero discharge system is a specialized treatment system specially developed for the tailings dry discharge and tailings slurry zero discharge in the mine beneficiation industry.

Selection of width and length of the screen surface The width and length of the screen surface is an important process parameter for the screen. Generally speaking, the width of the sieve surface determines the processing capacity of the screening machine. The length of the sieve surface determines the screening efficiency of the screening machine. Therefore, the width and length of the sieve surface are correctly selected to improve the production capacity and screening of the vibrating screen machine . Efficiency is very important. The width of the screen surface is not only affected by the processing capacity of the screen, but also by the structural strength of the screen. The larger the width, the more certain the size of the screening machine is. The more problems that need to be solved in the structural strength of the screening machine , the more difficult it is, so the width of the screen surface cannot be arbitrarily increased. The length of the screen surface affec...
