1. Product description
The main function of the fine sand recovery machine is to clean,
dehydrate and classify the sand. It can recover a large amount of
fine sand lost by the sand washing machine in the traditional sand
making industry. The fine sand recovery machine mainly plays the
role of water sand separation
The common materials are: kaolin, mud, sand aggregate, artificial
sand, coarse coal slime, concrete mixing plant and other fine
materials recycling.

3. Product advantages
1. It can effectively reduce the loss of fine particles and solve
the problems of high fineness modulus and low stone powder content
in the finished product.
2. 95% of the total amount of fine particles can be recovered,
which has incomparable technical and economic advantages compared
with other equipment.
3. Simple operation, convenient maintenance, high degree of
intelligence, greatly reducing the input of manpower
4. working principle
The sand washing wastewater overflowed by the sand washer is
connected with the cleaning tank of the fine sand recovery machine,
and then the sand water mixture in the cleaning phase is
transported to the mud high-pressure separator through the slurry
pump. The fine sand in the slurry is separated by the cyclone
through the high-speed centrifugal force and the rated feeding
pressure, and the fine sand is provided to the dewatering screen
through the sand settling nozzle. Under the effect of the vibration
of the screen, the fine sand and water are effectively separated.
The treated fine sand is discharged through the discharge port, and
a small amount of fine sand and mud are returned to the cleaning
tank through the return box, so as to realize the purpose of
recovery, dehydration and dry discharge of the fine sand in the
sand washing wastewater. The fineness modulus can be adjusted by
changing the pump speed, changing the mortar concentration,
adjusting the overflow water volume and replacing the mortar
nozzle.
