In the end of the sand production line, for sand with a large mud content or sand-water mixture with a large sand content, only the sand washing machine may not meet the requirements of the final finished sand, and there is a serious drawback of the loss of fine sand. To solve this problem, it is necessary to use a fine sand recovery system. This article introduces 4 methods for your reference.
Fine sand recycling machine
As the name suggests, the fine sand recovery machine is a commonly used fine sand recovery equipment, which needs to be used in conjunction 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 (the loss can be up to 20% or more). While improving economic efficiency, it reduces the cost of tailings treatment and the pollution and damage to the environment caused by the loss of fine sand.
When the fine sand recovery machine is used in a sand and gravel plant, the main function is water washing sand and sediment separation, so it is also called a fine sand dewatering machine, a sediment separator, and a sediment extraction machine; when used in a concentrator, the main function is tailings recovery. So it is also called tailings recovery machine.
Dewatering type fine sand recovery machine
The dewatering fine sand recovery machine is divided into two systems: dewatering and recycling. The dewatering part includes a dewatering screen and a vibration motor, and the recycling part includes a vacuum high-pressure pump, a motor, a high-pressure separator, a return tank, and a cleaning tank.
Generally installed directly at the back of the sand washer, the sand washed by the sand washer can be cleaned twice, and the waste water discharged by the sand washer can also be separated from the sand, which fully solves the shortcomings of the sand washer (such as: finished product) Large water content, large mud content, large dust, difficult to remove impurities, etc.), which greatly improves the quality of the finished product.
Sand washing & recycling machine
The structure of the sand washing & recycling integrated machine is composed of high-pressure separator, dewatering screen, impeller separator, reducer, vacuum high-pressure pump, cleaning tank, high-position return tank, motor, vibration motor and other components. The main function is to wash sand and fine sand at the same time.
Sand washing & dewatering machine
The sand washing & dewatering integrated machine combines the characteristics of sand washing machine & dewatering screen. The main function is to wash sand with water, and further desilting, dewatering and secondary cleaning.
