The scope of application and maintenance of spiral sand washing machine
Spiral sand washing machines are often used in the mining industry or in the construction and hydropower industries. How to maintain the spiral sand washing machine? This article will take you to learn more about the scope of application, maintenance, and comparison of the advantages of the spiral sand washer.
Matters needing attention during installation and operation of spiral sand washing machine
1. Due to the large torsion of the spiral sand washer, it is recommended to install the machine on a concrete foundation with embedded weldments for welding during installation. The depth and area of the foundation are calculated separately according to the soil conditions. The recommended basis weight is roughly the machine. 3 times the weight, please refer to the basic drawing for the installation dimensions of the machine.
2. After the screw sand washer is installed in place, check whether the gears of the reducer are shifted and whether the gap between the water tank and the large bucket is consistent. After adjustment, the machine is fixed and welded to the foundation.
3. The spiral sand washing machine should be filled with lubricating oil and the height of the oil level should be adjusted. Generally, it is appropriate to take 50 below the shaft center.
4. After the screw sand washer machine is installed and adjusted properly, carry out a test run, and the no-load test run should be reached. The following points should be paid attention to when the spiral sand washer is running dry.
1) After continuous operation for 2 hours, all solid parts should be firm without looseness.
2) There is no abnormal noise from the reducer and gearbox.
5. In addition to the load test run of the spiral sand washer, the following requirements should be met in addition to the no-load test run requirements.
1) When feeding, do not make the material strongly impact the water tank, do not allow partial load feeding, and fill the water tank to avoid damage to the bucket and the body.
2) The largeness of the feed is in compliance with the design regulations.
The spiral sand washing machine is used for desliming and screening operations of large amounts of sand and gravel used in construction sites, sand and gravel plants, prefabrication plants, and hydropower sites, and can also be used for ore sorting operations. It can effectively process materials within 0-10mm and can separate the soil and ash on the materials into clean materials. This machine has the advantages of simple structure, easy maintenance, and high washing efficiency. The spiral sand washing machine is divided into a double spiral and a single spiral. Compared with the single-screw sand washer, the double-screw sand washer has the characteristics of high efficiency and large output and can process materials within 0-30mm. The double spiral sand washing machine has the characteristics of simple structure, easy maintenance, and high washing efficiency. The rotor of the double spiral sand washing machine adopts a central structure, the spiral blades are installed on the central shaft, and the reducer is connected to the central shaft for work. Relying on the principle that the solid particles have different specific gravities, so the sedimentation speed in the liquid is different, it is a kind of ore cleaning equipment for mechanical separation.
