Profile

XL Model Sand and Gravel Washer is a kind of high efficiency bucket wheel washing equipment combined with sand making machine in domestic sand and gravel industry. The equipment has three functions of cleaning, dewatering and grading; it is suitable for construction site, sand and gravel plant, hydropower station, pressure sand in backfill of oil well’s cleaning, grading and dewatering. Suitable for fine grain and coarse particle size materials cleaning operation, it is especially suitable for building sand and road building sand. XL Model Sand and Gravel Washer can effectively deal with the material within 0-30mm, and the soil and ash powder can be washed into clean materials separately. This machine has the advantages of simple structure, easy maintenance and high washing efficiency and so on. Spiral sand washing machine is divided into double helix and single screw. Double helix spiral stone washing machine compared to the single screw spiral sand washing machine features high efficiency, high yield .

Working principle

When the XL Model Sand and Gravel Washer working, after the motor is decelerated by V-belt, reducer and gear, then it drive the impeller to rotate slowly; Gravel from the feed tank into the wash sink, driving impeller to roll, and make the materials grind by themself. Remove the impurities what covering the surface of sand and gravel; At the same time, the water vapor layer of the surface sand is destroyed to facilitate dehydration. Then, fill water to form strong water flow, the impurities and foreign bodies with small specific gravity can be removed in time, discharged from the overiall of sink to complete cleaning work. Clean sand and gravel carried away by blades, gravels pours into gutter from the rotating impeller to complete cleaning work of gravel.

Installation

The installation, adjustment and operation of the machine assembled by the manufacturer, and after passing the run-in test to supply, users should carefully check after receiving machines, in order to find the possible problems in transit. Attention should be paid to the installation, adjustment and operation of the machine:

- Due to the large torsion of the machine, it is suggested that the machine be installed on the concrete foundation, an pre embedded welding parts for installation welding on the foundation. The depth and area of the foundation are calculated separately according to the soil conditions, suggestion that the foundation weight be approximately 3 times the weight of the machine.

- After installation, should be checked whether the big size gear and small size gear of reducer is shifting, whether the water tank is in accordance with the clearance of the large wheel bucket. After the adjustment, fixed welding the machine on the foundation.

- Lubricating oil should be filled and adjust the height of the oil surface, generally take 50% below of the center shaft.

- After the installation and adjustment of the machine, the test run is carried out, no load test run should be reached:

1.Continuous operation for 2 hours.

All solid parts should be firm and no looseness appearance.

The reducer and gearbox without abnormal voice.

- In addition to the no-load test requirements, the load test should also meet the following requirements:

1.When feeding, can not make the materials strongly impact the water tank; Not allowed charging with unbalance loading and push the full water tank, in order to avoid to damage the bucket and the organism.

2.For the largest size material has been designed to meet the design requirements.
