矿山设备指南：What Equipment Should You Use for Manufactured Sand Washing and Severe Fine Sand Loss? A Complete Guide to Sand Washing Recovery Integrated Machines and Fine Sand Recycling Machines

The sand washing and recovery all-in-one machine has been continuously innovating over the years and communicates with customers to develop new products based on different customer requirements. This machine has a reasonable structure, small footprint, and high efficiency. In traditional sand washing, fine sand loss is severe, occupying space and labor. This machine can effectively control fine sand loss, improve sand quality, control the sand volume in concrete, reduce cement usage, and increase the economic benefits of the sand washing plant. The fine sand recovery machine absorbs advanced foreign technology and is carefully designed according to China's actual conditions. It is widely used in hydropower, glass factories, building materials sand and gravel fine grains, coal preparation plants for coarse coal slime recovery, and environmental protection projects (such as slurry purification). Its working principle is that the pump conveys the slurry sand-water mixture to the high-pressure separator for mud and sand; the fine sand concentrated by centrifugal classification is supplied to the dewatering screen via the sediment nozzle. After dewatering on the screen, fine sand and water are effectively separated, and small amounts of fine sand, mud, etc., are returned to the washing tank via the return box. When the washing tank liquid level is too high, it is discharged through the outlet. The dewatering screen recovers material with a weight concentration of 70%-85%. The fineness modulus can be adjusted by changing the pump speed, slurry concentration, overflow water volume, or replacing the sand outlet nozzle, thereby completing washing, dewatering, and grading functions. Why choose these two types of equipment? Because they effectively solve the problems of severe fine sand loss, land and labor occupation, and low economic efficiency in traditional sand washing, while achieving slurry purification and resource recycling in environmental engineering. They are ideal choices for upgrading sand and gravel plants, coal preparation plants, hydropower projects, and environmental protection projects. When should this equipment be chosen? When severe fine sand loss occurs in traditional sand washing lines, the finished sand grading is unreasonable, concrete cement usage is excessive, or when slurry needs to be treated and coarse coal slime recovered, the sand washing and recovery all-in-one machine or fine sand recovery machine should be prioritized. How to choose? It is necessary to select the XSHJX series model of the sand washing and recovery all-in-one machine according to material characteristics (sand-water mixture concentration, fine sand content), and choose motor power and dimensions according to processing capacity and water treatment volume. The fine sand recovery machine requires selecting the corresponding WS series or 2WS series model according to separator specifications, dewatering screen size, pump power, and processing capacity, and fineness modulus can be adjusted by changing pump speed, slurry concentration, overflow water volume, and sand outlet nozzle.
