At present, there have been a large number of manufacturers of fine sand recycling machines in the domestic market. The quality of equipment price uneven, our company in order to ensure the leading position in the industry ranked dry washed sand and tailings, better service to our customers, each place, geographic differences, independent research and development of sand washing dewatering machine a recovery of three, Sunaba in the construction process more reasonable and simple, in the sand sand washing dehydration equipment recycling industry production enterprises in a way ahead. At the same time, the equipment overcame all the shortcomings of the fine sand recovery machine in the existing market (fine sand and coarse sand mixed unevenly, and fine sand and so on). It has the advantages of uniform division of coarse and fine sand, reasonable gradation and so on.
It is composed of electric motor, hydrocyclone, heavy dewatering screen, slurry pump, storage tank, return box, connecting pipe and so on.
The mixture of sand and water enter the heavy duty dewatering screen or light dewatering screen. Most of the coarse and coarse sand is dehydrated through sieve, dehydrated and transported to the middle part of the dewatering screen. At the same time due to buoyancy most of the water and sand through the filter separator into the storage tank through the slurry storage tank of water and sand transported to the hydrocyclone, and fine sand centrifugal classification after enrichment, the middle water cyclone sand outlet into the heavy part of the dewatering screen position coarse, medium and fine three kinds of sand in the two sieve dehydration dehydration, after mixing into the belt conveyor outlet in dewatering screen. The waste water, mud, powder layer and impurities in the storage box are discharged through the overflow of the cyclone.
四、特点和优势Characteristics and advantages：
The equipment has the function of sand washing, dehydration and fine sand recovery, and it is completely replaced by the original wheel bucket sanding machine or the spiral sand washing machine
The equipment has the advantages of simple structure, convenient installation, low cost, small area and high quality of sand.
Strong heavy structure, very suitable for harsh operating environment
High cleanliness, less loss of fine sand and great handling capacity
hydrocyclone, the downward spiral feeding mode, high efficiency, thorough separation of 75 mu m or less impurities; and cyclone can be adjusted according to the size of the water, water can be large open at the same time, when a small amount of water can be only two or three
high frequency linear dehydration screen, dehydration effect is the best, water content after dehydration about 10%-15%
High chromium alloy slurry pump, high efficiency and energy saving, small vibration, low noise, reliable operation and long service life
Reduce the main recyclable material into the sedimentation tank, reduce the maintenance of the sedimentation tank and save the cost
All wear areas are made of special wear resistant materials to prolong the service life.
