Introduction to Fine Sand Recycling Machine

The fine sand recycling machine is a device developed by Jihong Machinery for the dehydration, desilting, and desilting of slurry materials. Its biggest feature is that it can effectively solve the problem of fine sand loss in the sand making industry, making it Jihong Machinery's flagship product.
From the perspective of large and medium-sized stone factories, sand washing plants, and manual sand production lines at home and abroad, more than 90% of them use wet production lines, generally using silos → feeders → crushers (primary or secondary, tertiary crushing equipment) → washing equipment (spiral sand washing machine or impeller sand washing machine) → screening equipment → finished materials. As the name suggests, a wet production line uses washed aggregates, which inevitably leads to the loss of some finished sand from the sand washing machine, especially fine sand below 0.16-0.2mm, with a loss rate of over 20%. The consequences of this are as follows:
1. The loss of fine sand below 0.2mm affects the grading of sand, resulting in unreasonable grading and fineness modulus, greatly reducing the product quality of machine-made sand;
2. Excessive fine sand and sludge entering the sedimentation tank can cause sedimentation, which not only pollutes the environment but also incurs high costs for frequent cleaning;
3. A large amount of fine sand is lost, greatly reducing the customer's revenue.
To solve the above problems, our company has successfully developed a fine sand recovery machine. This machine is an advanced fine material extraction device designed by absorbing advanced foreign technology and combining it with the actual situation of sand powder. It is widely used in sand and gravel processing systems of hydropower stations, glass raw material processing systems, manual sand production lines, coarse coal slurry recovery in coal preparation plants, and environmental protection engineering (mud purification), which can effectively solve the problem of fine sand recovery.

Structure and working principle of fine sand recycling machine

The fine sand recycling machine is designed reasonably and easy to use, mainly consisting of the following structural components: motor, vacuum high-pressure pump, sediment separator, TS dewatering screen, cleaning tank, and return box.
Working principle of fine sand recycling machine: The pump slurry sand water mixture is transported to the mud and sand high-pressure separator. The fine sand that is centrifuged and concentrated is provided to the dewatering screen through the settling nozzle. After dewatering by the dewatering screen, the fine sand and water are effectively separated. A small amount of fine sand, mud, etc. are returned to the cleaning tank through the return bin. When the liquid level in the cleaning tank is too high, they are discharged through the discharge port. The weight concentration of the recovered material through dehydration screening is 70% -85%. Adjusting the fineness modulus can be achieved by changing the pump speed, changing the mortar concentration, adjusting the overflow water volume, and replacing the mortar nozzle. Thus completing three functions: cleaning, dehydration, and grading.

Advantages of fine sand recycling machine

1. The recovery efficiency of fine sand is as high as 95%
The fine sand recovery equipment adopts a semi closed design, and after separation, sediment and wastewater will be discharged from the upper part of the cyclone. The discharge and multiple recycling of waste materials achieve a recovery rate of over 95%.
2. Durable and long-lasting, with a long service life
In response to the serious wear and tear of fine sand recovery equipment, R&D personnel proposed to use special materials to reinforce the vulnerable structures of key equipment components from the beginning of the design of fine sand recovery equipment, in order to extend the service life of the equipment.
3. Economic and environmental protection, reducing pollution, creating revenue
The research and development of fine sand recycling machines not only improves the quality of sand and gravel materials. At the same time, the efficient recovery of particulate materials has enabled them to be widely used in environmental protection projects, achieving both economic and environmental benefits.
4. Widely applicable materials, diverse industries, and strong practicality
The fine sand recycling machine can be applied to manual sand production lines, mud purification, hydropower station sand and gravel aggregate systems, glass raw material processing systems, and the recycling of coarse coal slurry in coal preparation plants.
