1. The sand bucket structure of the excavator is clear, and the seal of the hydraulic transmission bearing device is good, so as to avoid bearing damage caused by water, sand and pollutants.

2. Sand washing machine (sand washing machine) used for sand washing in sand and gravel field has obvious characteristics compared with the traditional wheel sand washing machine:

A. Fine sand and stone powder will not be lost, and the sand gradation and fineness modulus of the washed building sand reach the scale of "construction sand" and "construction pebble and gravel" in China

B. Dredge installation sand washing machine has almost no wearing parts except the screen.

C. Long service life, no maintenance for a long time

3. Sand washing machine has simple structure, convenient maintenance, large processing capacity, small power consumption and high cleaning degree. Hydraulic seal structure, planetary transmission deceleration device, adjustable overflow weir plate, ensure that the series of products are efficient, durable, cleaning, dehydration effect is good, fine grain products to maintain the characteristics of not random.

4. Rotary sand washer is widely used in construction sites, sand factories, railway construction, highway construction, viaduct construction, concrete mixing station, concrete dam construction site of hydropower station and other industries with high requirements on sand quality
