Sand washing machine is one for artificial sand and natural sand washing equipment, can be widely used in gravel pits, mining, building materials, water conservancy and hydropower, concrete mixing plant and other industries in the washing of the material, it can remove cover in sand impurities stone surface, while destruction of vapor-coated sand layer, in order to facilitate dewatering, played the role of efficient cleaning. We used sand washing machine is mainly divided into two types, namely, bucket wheel sand washing machine and spiral sand washing machine. The following article describes both to sand washing machine working principle and application ranges.
First, bucket wheel sand washing machine
1, the working principle
When the bucket wheel sand washing machine working motor through V-belt, reducer, gear reducer drive after slowly rotating impeller, sand and gravel into the wash tank has to trough, rolling driven impeller and grinding each other, covered with sand and gravel out surface impurities, while broken-coated sand vapor layer to facilitate dehydration; while adding water to form a powerful water flow, timely small proportion of impurities and foreign matter away and wash tank from the overflow outlet, complete cleaning action. Clean sand oil blade away from the last rotation of the impeller into the gravel out of the trough, complete cleaning action gravel.
2. Applications
Bucket wheel sand washing machine reasonable structure, large capacity, low power consumption, clean and high, at least in the process of sand washing sand churn rate, it can be widely used in gravel pits, mining, building materials, transportation, chemical industry, washing water conservancy and hydropower, concrete mixing stations and other industries of materials, grading and dehydration, is an excellent choice for domestic sand washing industry upgrading.
Second, the spiral sand washing machine
1, the working principle
Spiral sand washing machine working process is connected by an electric motor through reducer rotating, perforated plate from the bottom of the sedimentation tank to the wash water. Its sand washing process is divided into three parts, namely cleaning, dehydration, classification:
(1) Cleaning: gravel into the sedimentation tank by the helical blade action to make gravel tumbling and grinding each other to remove impurities on the sand covering the surface of the washing water is formed by the perforated plates rising water, the small proportion of foreign matter from the water overflow weir outside, thereby completing the cleaning action.
(2) dehydration: the proportion of larger particles sink to the bottom, the bottom side bending, the spiral blade will advance up the gravel. Because the water tank has a horizontal length exceeds the lower part of the right length, in advancing up the process, to remove excess moisture sand, prolapse of the water flowing into the sedimentation tank drains from the bottom on the other side, the upper end of the gravel from the tank bottom discharge discharge port.
(3) Classification: Classification material is not meet the standards by the fine particle overflow weir foreign achieve that control measures are: to adjust the weir height and speed adjustment screw. When cleaning equipment, first shed 4 plug, then turn on the water wash, fine particles and debris from the waste outlet from the plane.
2. Applications
Spiral sand washing machine has a simple structure, stable operation, sand washing clean, high yield notable features. It is widely used among the construction sites, gravel pits, glass, power plants, concrete prefabricated stone and electricians to other departments.
