Introduction of spiral stone washing machine:
Working principle
The buoyancy of water is used to separate dust and impurities from sand. With the help of the principle that solid particles have different settling speeds in liquid, the purpose of filtering water, removing impurities and lifting and conveying is achieved through the stirring of the spiral blades, while the sand is evenly mixed.
Structural composition
It consists of a tank body, a reducer, a motor, a central shaft, spiral blades, a bracket, etc. The bracket is welded on the central shaft, and the spiral blades are tightened and fixed with bolts to prevent sagging and deformation.
Performance characteristics
Strong processing capacity: It can meet the cleanliness requirements of ore and stone materials for large productivity, and the processing capacity ranges from a few tons to hundreds of tons per hour.
High washing degree: It can effectively remove impurities such as soil and dust in sand and gravel, so that the mud content and water content of the finished sand and gravel are low.
Simple structure: The overall structure is relatively simple and there are no complex components, so it is easy to maintain and the maintenance cost is low.
Long service life: The key components are made of high-quality materials, such as the spiral blades are made of wear-resistant materials. With reasonable structural design, the equipment runs stably and has a long service life.
Scope of application
It is suitable for construction sites, sand and gravel plants, concrete prefabrication plants and hydropower sites, etc. It can remove mud and powder from various raw materials such as river pebbles and artificially mined rocks, and can also be used for washing, grading and dehydrating ore.
Classification
According to the number of spirals: there are single spiral stone washing machines and double spiral stone washing machines. Single spiral stone washing machines are suitable for occasions with small processing volume; double spiral stone washing machines have large processing capacity and better cleaning effect.
According to weight type: there are light and heavy types. Light spiral stone washing machines are suitable for processing materials with small particle size and low hardness; heavy spiral stone washing machines can process ores and stones with large particle size and high hardness.
Precautions
Installation and debugging: During installation, the inclination angle of the machine must be ensured, and the motor is installed on the guide rail to adjust the belt tightness. After installation, no-load and load operation tests are required.
Operation and use: Before starting, check whether there are any abnormalities in all parts of the machine. Repairs and cleaning work cannot be carried out during operation. Stones exceeding the specified size must not be added, and the machine should rotate in a fixed direction.
Maintenance: Check the wear of each component regularly, lubricate the bearings and other parts well, and replace severely worn parts in time.
