Gearing device: include motor, size pulley, triangle belt and reducer.

Spiral: including screw shaft, blade, liner. The rotation of the screw axis is dextral.The blade is solid; Lining board materials have manganese vanadium titanium wear – resistant cast iron, polyurethane. When the liner is worn out of use, it can be removed and replaced with a new liner. The liner is mounted with bolts, nuts and washers on the forward side of the screw in connection with the blade and overlaps with the blade for protection. The two ends of the spiral shaft are welded with flanges, which are respectively connected with the upper support and the lower support to meet the requirements of sand and stone washing, classification and dehydration.

1. Due to the large twist of the machine, it is recommended to install the spiral sand washer on the concrete foundation. There are pre-embedded weldments on the foundation for welding during installation. The depth and area of the foundation are calculated separately according to the soil conditions. The recommended foundation weight is approximately 3 times the weight of the machine. For the installation dimensions of the machine, refer to the foundation drawing.

2. After installation, you should check whether the gears of the reducer are shifted, and the gap between the water tank and the big bucket is consistent. After adjustment, the machine is fixed and welded on the foundation.

3. Should be filled with lubricating oil, adjust the height of the oil level, generally take the shaft center below 50% is appropriate.

4. The load test should meet the following requirements: (1) When feeding, the material must not be strongly impacted on the water tank, and it is not allowed to load and stack the water tank unbalanced to avoid damage to the bucket and the body. (2) The relatively large feed rate meets the design requirements.
