The spiral sand washing machine
is the main washing equipment for artificial sand. It is widely used in the washing of materials in industries such as gravel yard, mining, building materials, transportation, chemical industry, water conservancy and hydropower, and concrete mixing station.
1. Sand and stone washing operation can prevent clogging of ore bins, chutes, hoppers, crushing and screening equipment, etc., so that the processing capacity of the crushing and screening equipment is reduced. When the clogging is serious, production cannot proceed normally.
2. Obtain concentrates; some ores can be enriched with useful minerals through washing to obtain qualified concentrates, such as some deposited manganese ore, apatite ore, iron oxide ore, etc.
3. Limestone for smelting can be cleaned by washing the ore to improve the quality to meet the smelting requirements, such as Chuanshan limestone mine, Wulongquan limestone mine, etc.
The ore washing machine is widely used in construction sites, sand and gravel plants (sand and stone plants), hydropower station concrete dam construction sites and other industries. Medium), in addition, the transmission part of the spiral sand washer is completely isolated from water and sand, so its failure rate is far lower than the current commonly used spiral sand washer equipment, which is a reasonable choice for upgrading and replacement of the sand washing industry.
When the screw sand washing machine is working, the motor drives the impeller to slowly rotate after decelerating through the V-belt, reducer, and gear. The sand and stone feed trough enters the washing tank. The impeller drives the roller to roll and grind each other to remove the covered sand stone surface. Impurities, at the same time destroy the water vapor layer covering the sand particles to facilitate dehydration; at the same time, add water to form a strong water flow, promptly remove impurities and foreign objects with small specific gravity, and discharge from the overflow tank to complete the cleaning function, clean sand Taken away by the blades, the sand and stone are poured from the rotating impeller into the discharge trough to complete the cleaning of the sand and stone.
