Polishing machine is used for surface polishing of materials, and is commonly used for polishing of various beans and grains. It can remove dust and attachments on the surface of material particles, making the surface of the particles bright and beautiful.
Polishing machine is a key equipment in cleaning beans, seeds and grains. It combines physical friction with airflow screening to achieve multi-dimensional impurity removal and quality optimization.
1. Working principle of polishing machine
The working principle of the polishing machine is to stir the material with a rotating cotton cloth, and at the same time use the cotton cloth to wipe off the dust and attachments on the surface of the material, so that the surface of the particles looks bright and new. The internal structure of the polishing machine includes a central axis, an outer cylinder, a frame, etc. A large amount of cotton cloth is fixed on the surface of the central axis. The cotton cloth is installed in a specific structure and specific trajectory. The outer cylinder is the cylinder wall of the polishing work. A woven mesh with holes is used to discharge the dust generated by polishing in time. The equipment has a feeding inlet, a finished product outlet, and a dust outlet. When in use, it should be connected to a hoist or other feeding material.
2、The core role of polishing machine in cleaning
（1）Precise removal of surface impurities: remove dirt and dust attached to the surface of seeds (removal rate of more than 95%)
（2）Pathological impurities treatment:Rubbing to remove disease spots and insect infestation marks (such as soybean gray spot disease spots) on the seed surface, reducing the probability of pathogen transmission;
（3）Quality grading and commercial improvement: By controlling the polishing intensity (rotation speed, friction time), the seeds are graded according to glossiness and integrity. The selling price of polished beans and grains can be increased by 10%-20%.
（4）Application in seed production industry: Polishing of hybrid seeds can remove residual pollen and seed coat debris from the male parent, avoid mechanical mixing, and ensure seed purity.
3. Technical advantages of polishing operations
（1）Metal spindle:The center shaft adopts metal spindle, and the cotton cloth is fixed to the spindle surface with bolts to increase the spindle life and facilitate the replacement of cotton cloth.
（2）Pure cotton cloth:The polishing cloth adopts pure cotton leather, which has the characteristics of good adsorption and improves the polishing effect Replace the pure cotton cloth after 1000T.
（3）304 stainless steel mesh：The outer cylinder adopts 304 stainless steel woven mesh, which has excellent durability and ensures the overall service life of the equipment.
（4）Fan dust removal：The entire polishing room is carried out in the state of suction negative pressure, and the generated dust can be discharged in time to avoid dust accumulation and affect the polishing effect.
