Washed sand is construction sand that is obtained after the natural silica sand is washed by a sand washing machine and meets the construction standards of various places. Both artificial sand and natural sand contain certain impurities. If such sand is used for the construction of the project, it will result in a strong degree of engineering. Therefore, the sand washing machine equipment should be used to clean the impurities in the prepared sand to complete various construction requirements. The silica sand washing production line is a system solution for the problems of dry piles, tail water purification, dry waste discharge and other issues. It mainly includes screening, cleaning, dehydration, fine material recovery, solid-liquid separation, sludge dewatering and other aspects. The material is effectively screened, washed and dewatered throughout the system. Save resources and reduce water consumption. The entire production line has excellent continuous working performance and ...

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...

LZZG sand-washing system has been loaded and sent to Yunnan. The production department has passed the video to allow Yunnan customers to test the machine, and then sent the equipment to the fine sand site for on-site installation and test operation. LZZG's sand washing system mainly includes screening, cleaning, dehydration, fine sand recovery, solid-liquid separation, sludge dewatering and other links. The material is effectively screened, washed and dewatered throughout the system. Save resources and reduce water consumption. The entire production line has excellent continuous working performance and convenient maintenance. Long service life, easy to move and excellent effect. At the same time, it ensures no pollution and meets environmental protection requirements. In the zero-emission system sent to Yunnan, the equipment for screening and dewatering is a spiral washing and returning machine. It is a kind of water-collecting and sand-sand material dehydration and r...

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. Due to the turning and rolling of the material in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from being clogged. During the use of the drum screen, the operation is slow and uniform, the impact vibration is small, the work is stable, the installation is simple, and no special foundation is needed. The installation angle is small and it is not easy to block. It can be placed direct...

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...
