Sand washer is widely used in a variety of industries ranging from chemical companies to sand manufacturers to turn sands or other raw materials into smaller particles. Besides, rock crusher is one of the important equipment in sand processing. It is used to crush such materials as rocks and iron. In general, a jaw crusher consists of a fixed crushing jaw and a moveable one and deals with incoming materials in a wedge-shaped crushing zone that churns centrifugally.
The processing procedures of silica sands, foundry sands, filter sands and sands of some other types vary with each other in complexity and the use of sand washers. Different physical and chemical properties can be produced in accordance with the requirements of customers. However, almost all sand processing include the following three stages: sand crushing, sand washing and size classification. With regard to sand washing, sand washer is frequently employed to deal with both natural sand and manufactured sand.
Typically, a sand washer is composed of a chassis, motors, sedimentation tanks, rotary bucket elevators, and gears. The chassis guarantees high strength and flexibility and can withstand great pressures while the rotary bucket elevators are used as storage areas for the washed sand. After sand has been separated, it is transferred by gear-controlled impellers into sedimentation tanks. In general, sand washers can be divided into multi-functional washing machines and exclusive ones. The former can be applied to wash slurry and mud that contain sand while the latter is exclusively designed to deal with sand with impurities.
The repair of sand washer includes routine maintenance, replacement of frequently used parts and solution to machine breakdown. In many cases, a professional mechanic is needed since the repair work requires specialist knowledge about the structure of sand washer, dynamics, and heavy machinery. The following tips are useful for both professional and amateur repairers of sand washer to get desirable results.
First of all, as with the repair of any heavy machinery, proper tools are expected to be prepared in advance. For example, failed parts may need to be removed in the first place with the help of metal cutting equipment, arc gouging or even plasma cutting equipment. In addition, basic knowledge about dynamics and the structure of sand washer is essential to the success of repair. A professional repairer may undergo several years of training and practice to do repairs safely and effectively.
Also the sand washer should be shut off in order to avoid possible accidents in the repair process. And when you are repairing the damaged part, remember to ensure that replacements fit well with the other parts and any fluids or rust in the joints should be removed. The time spent on such details can help prevent significant breakdowns in the future.
