How many kinds of belt are there in the sand washer?
A machine used for washing sand in a trough by means of a rotating spiral. In the process of washing, the sand washing machine can rush the fine particles in the sand, so it is also called a spiral classifier. The utility model is composed of a steel flume body, a spiral body, a power transmission device, a spiral lifting device, etc., and the water tank body is inclined to be installed, and the inclination angle is generally between 12 DEG C and 18 DEG C.
The sand washing machine is divided into 2 types of single helix and double spiral according to the spiral number, and the 2 spiral of the double spiral sand washing machine are relatively rotated, so that the sand accumulation can be brought together and discharged from the middle part. The immersion depth of the spiral body in the flume is divided into two parts:Low weir type sand washing machine. The overflow weir is lower than the center of the spiral support in the lower part of the trough, and the liquid area and capacity in the flume are smaller.High weir type sand washing machine. The weir is higher than the center of the spiral support in the lower part of the tank, but lower than the upper edge of the spiral. It is suitable for sand materials with grades larger than 0.15ram.Sink type sand washing machine. The overflow end of the spiral all sinks below the overflow surface and is suitable for grading sand less than 0.15ram. In the construction of water conservancy projects. The high weir single screw sand washer is usually used.
The bottom of the trough is semicircular and is fed by the lower end, and the discharge port is arranged at the bottom of the upper groove. Operation of sand washing machine, sand grinding by rod mill or by sieve screen sand material from the feed inlet water sand washing machine, coarse particles sink at the bottom of the groove by a spiral conveying to the upper end of the outlet, and then use the belt conveyor sent. During the settlement process, the fines, fines and impurities contained in the sand are washed with water and discharged by the overflow weir at the bottom of the tank. The sand washing machine is a kind of mining machine for shaping products. It is used for washing and washing of sand materials in the construction of water conservancy projects.
