Description

Technical Field

[0001] This application relates to the technical field of grinding processing, and in particular to a grinding device. Background Art

[0002] Calcium sulfate whisker is a new type of needle-shaped fiber sub-nano material that grows in the form of single crystals, has a uniform cross-section, a complete shape, and a perfect internal structure. Calcium sulfate whisker combines the advantages of both reinforcing fibers and ultra-fine inorganic fillers, and has a wide range of applications. It can be used as a reinforcing and toughening agent or functional filler in resins, plastics, rubbers, coatings, paints, paper, asphalt, friction and sealing materials; it can also be directly used as filter materials, thermal insulation materials, refractory and heat insulation materials, infrared reflection materials and high-insulation materials for coated wires.

[0003] When the applicant was conducting this application, through retrieval, it was found that the Chinese patent disclosed a "grinding device" with the application number "CN201921482799.7". This patent mainly uses a fixed grinding structure. When this grinding device is in use, its fixed grinding structure and only a single set of grinding groups are likely to result in uneven quality of the ground products, and reprocessing is required. Such operations lead to low production efficiency and poor production quality.

[0004] Therefore, we propose a calcium sulfate whisker grinding device. Summary of the Utility Model

[0005] The utility model provides a calcium sulfate whisker grinding device. Before use, pour calcium sulfate whisker into the grinding barrel, then start the machine. The servo motor gives power to the transmission rod to drive multiple crushing knife groups and crushing rods. The crushing knife groups will first break up the calcium sulfate whisker. After being processed into small particles, they will pass through the first filter plate and fall into the area of the crushing rods. At this time, the crushing rods will reprocess and roll the small-particle calcium sulfate whisker until it is rolled into powder and filtered through the second filter plate into the feeding port. After the switch valve is opened, the finally completed powdered calcium sulfate whisker will be discharged from the feeding port. The settings of the crushing knife groups and the crushing rods can first break up the calcium sulfate whisker and then grind it into powder, which can improve production efficiency and the quality of the final product.
