LZ sand washer machine

LZ sand washer machine is a kind of wheeled washing equipment and combined with dewatering screen and hydrocyclone, which can clean and separate the dust and powder from sand and gravel. Its new seal-structure and reliable driving device can make sure the effective cleaning and a kind of high efficiency sand washing equipment.


LZ sand washer machines are wheel bucket type washing equipment and are mainly used for washing, classifying, dewatering and fines recycling of sand. This machine adopting advanced technology for high efficient sand washing, developed according to practical conditions of sand industries to meet out the IS standard requirements of gradation in the final output sand. Sand washer can widely used in sand and gravel plants, washing plants,buildings site, concrete mixing, coal processing, tailings processing plants, hydropower station, etc.

Working principle

*Washing: The bucket is driven by the motor through the reducer and rotates in circle. There are many sand storage web grooves and bucket screen for sand storage and primary dewatering. When the bucket moves, sand can be put out by sand storage web groove after being cleaned in the cleaning tank and primary dewatered on the bucket screen. *Recycling: Flowing slurry water is extracted by slurry pump, fine sand is collected by the centrifugal force of the cyclone, then fed to the polyurethane screen from the apex spray. The 0.074-3mm fine sand and water are efficiently separated through the vibration screen. *Dewatering: coarse sand (3-10mm) and fine sand (0.074-3mm) are fed onto polyurethane vibrating screen for dewatering.
