Working Principle Manual of Spiral Sand Washer

A spiral sand washing machine is often used in the last step of the sand washing operation of the sand production line, and it is also an indispensable sand washing machine in the sand washing production line. If you do not pay attention to the correct operation during use, it is easy to cause the output of the spiral sand washer to below. It greatly affects the production efficiency of the entire sand washing line and directly causes economic losses. To avoid these situations, what are the operations that need to be paid attention to when using the spiral sand washer?

Spiral Sand Washer

1. Introduction of spiral sand washing machine

Spiral sand washer is divided into a single spiral sand washer and a double spiral sand washer. It is mainly used for washing, grading, impurity removal in highway, hydropower, construction, and other industries, as well as washing and selecting fine-grained and coarse-grained materials. . It has low power consumption and high cleanliness. Good sealing structure, fully enclosed transmission device, adjustable weir plate. It ensures that the equipment is highly efficient, durable, has good cleaning and dehydration effects, and the fine-grained products remain stable.

Performance characteristics

The feed size is less than or equal to 10mm. The processing capacity is 30-240t/h. The spiral sand washing machine can process materials within 0-30mm and can separate the soil and ash on the materials into clean materials. This machine has the characteristics of simple structure, easy maintenance, and high washing efficiency.

Machine structure

The spiral sand washing machine is composed of a tank, a reducer, a motor, a central shaft, a spiral blade, and a bracket. The bracket is welded on the central shaft, and the screw blades are installed and tightened with bolts to prevent the blades from sagging and deforming.

working principle

The machine rotor adopts a central structure, the spiral blades are installed on the central shaft, and a reducer is connected to the central shaft for work. It is a kind of equipment for mechanical separation based on the principle that the solid particles have different specific gravities, so the sedimentation speed in the liquid is different.

2. Operating principle of spiral sand washing machine

The raw material contains a large amount of mud and impurities. If the raw materials fed by the spiral sand washer contain too much soil and impurities, it will take more time to wash the raw materials. Too much soil is washed away during the sand washing process, which will result in a low output of sand and gravel. Therefore, it is normal that the output of the spiral sand washing machine cannot meet the demand. Given this situation of raw materials, we can consider adding spiral sand washing machines and combined sand washing, which can effectively improve the cleanliness of materials while improving efficiency.

Poor machine performance

The spiral sand washer seems to have a simple mechanism, but in the production process of different manufacturers, the slight differences in the structure and size of the spiral sand washer may ultimately affect the output in actual production. According to the production experience and users of each manufacturer, The feedback situation will be adjusted and different. In poor-quality spiral sand washing machines, the sand cannot be separated from foreign matter, which affects the quality of the sand.

Operation technology

The use of the spiral sand washer is also very important for the operation of the equipment. This link is directly affected by the operator’s technical level. Improper operation not only affects the normal production of the equipment, directly affects the production efficiency, and even causes The spiral sand washer to be damaged.

In addition to the above reasons, the inadequate maintenance of the spiral sand washer can easily lead to the phenomenon of low output during the use of the equipment, so the regular maintenance of the equipment is also very important.

3. Installation guide for spiral sand washing machine

Installation, adjustment, and operation of the machine After the machine is assembled in the factory and passed the empty car test, it will be supplied as a unit. The user should check it carefully after receiving the goods. To discover and eliminate the problems that may be caused during transportation in time, the machine must be installed, adjusted, and operated in the correct way to ensure the normal operation of the spiral sand washer.

4. Precautions

1)The machine should rotate in a fixed direction, not reverse rotation.

2)The machine is running. If abnormal vibration or noise is found, the feeding should be stopped immediately. After the materials in the box are exhausted, immediately stop the motor, shut down and check, and then continue to run after troubleshooting. In case of tight conditions, stop the motor first, clear the material in the cavity before starting the machine, and start without load.

3)Do not add sand and gravel materials beyond the specified size.

4)Always check that all solid parts should be firm and not loose. There is no abnormal noise from the reducer and gearbox.
