Fine sand recovery machine

Description

The fine sand recovery machine mainly solves the problem of fine sand and fine material recovery through sand separation and fine sand extraction and collection, so it is also called sand separator, fine sand extraction machine, fine sand collection machine, tailings recovery machine, which can be installed at the end of the sand and stone production line or beneficiation production line, that is, behind the sand washing machine and the ball mill magnetic separator, the fine sand recovery machine is added. On the one hand, it can reduce the amount of fine sand loss and reduce environmental pollution, and on the other hand, make full use of fine sand. The rate of return of the enterprise and the economic value of the material.

Performance Advantages

In the traditional wet processing technology of artificial sand, the spiral sand washing machine used for mud washing and dehydration of artificial sand can hardly control the loss of fine sand in artificial sand. The fine sand recovery machine can effectively reduce the loss of fine sand, so that it is controlled within 5%-10%, which solves the problem of high fineness modulus of finished sand and low stone powder content in the artificial aggregate processing system.

• 1、The sand washing is clean, the recovery rate is high, the finished sand is washed and dehydrated twice, and the fine sand recovery effect can reach 80%-90%.
• 2、The fine particles are fully recovered, reducing the workload of the sedimentation tank and reducing the cleaning cost of the bottom tank
• 3、Both cleaning, dehydration, recycling three functions, saving cost and floor space.
• 4、The vibrating screen uses a polyurethane screen, which has a longer life than other types of screens and does not block holes.

Working Principle

The main structural components of BX fine sand recovery machine are: motor, vacuum high pressure pump, sediment separator, ZKR dewatering screen, cleaning tank, return box and so on. When working, the slurry sand water mixture is transported to the mud sand high-pressure separator, and the tailing sand with centrifugal classification concentration is provided to the dewatering screen through the settling nozzle. After dewatering through the dewatering screen, the tailing sand and water are effectively separated, and a small amount of tailing sand and mud are returned to the cleaning tank through the return tank. When the liquid level of the cleaning tank is too high, it is discharged through the discharge port. The weight concentration of the recovered material of the dewatering screen is 70%-85%, and the fineness modulus can be adjusted by changing the pump speed, changing the mortar concentration, adjusting the overflow water and replacing the mortar nozzle. To complete the three functions of cleaning, dehydration and classification.

Question&Answer

Q：Should the fine sand recovery machine be used together with the sand washing machine?

A：In the sand production line, the fine sand recovery machine is mainly used after the sand washing machine (used with the sand washing machine) to recover a large amount of fine sand lost by the sand washing machine in the traditional sand making industry (up to more than 20% when the loss is serious), improve economic benefits, and reduce the treatment cost of the tail material and the pollution and damage caused by the loss of fine sand to the environment.

Q：What is the main difference between the fine sand recovery machine and the sand washing recovery machine?

A：In simple terms, the sand washing and recycling machine is divided into sand washing parts and fine sand recovery parts, two major parts: impeller type sand washing machine + fine sand recovery machine (general fine sand recovery machine or dehydrated fine sand recovery machine, can also be configured according to the sand requirements of multi-layer dehydration screen), it is easy to distinguish.

Q：In addition to the fine sand recovery machine, what are the other ways to prevent the loss of fine sand?

A：The fine sand can also be recovered by using multi-stage sedimentation tank precipitation, equipped with dewatering screen, adding chemical agents, and configuring an integrated sand washing and recycling machine. It is no longer necessary to add a separate sand washing machine when configuring the integrated sand washing and recycling machine.
