Drying and pulverizing device for nano calcium carbonate

Abstract

The invention belongs to the technical field of nano calcium carbonate, and particularly relates to a drying and pulverizing device for the nano calcium carbonate. The drying and pulverizing device comprises a drying device, a pulverizing device and a control device; and the pulverizing device comprises a pulverizing mechanism and a grinding mechanism, the drying device comprises a containing barrel and an electric heating assembly, the control device comprises a controller and a sensor assembly, the pulverizing mechanism comprises a pulverizing portion and a rotating assembly, the grinding mechanism comprises a grinding assembly and a driving assembly, and the driving assembly and the rotating assembly are electrically connected to the controller. The drying and pulverizing device combines the drying device and the pulverizing device into one device and saves the working space; and the dried nano calcium carbonate can agglomerate, so that the manual conveying step is saved, the dryingand pulverizing efficiency is improved, and the labor cost is liberated.

Description

technical field [0001] The invention belongs to the technical field of nano calcium carbonate, in particular, the invention relates to a dry crushing device of nano calcium carbonate. Background technique [0002] Nano-calcium carbonate is also known as ultra-fine calcium carbonate. The most mature industry for nano-calcium carbonate is the plastic industry. It is mainly used in high-grade plastic products. It can improve the rheology of plastic masterbatch and improve its formability. It can be used as plastic filler with toughening and reinforcing properties. Strong effect, improve the flexural strength and flexural modulus, thermal deformation temperature and dimensional stability of plastics, and at the same time endow plastics with thermal hysteresis. The use of nano-calcium carbonate in ink products reflects excellent dispersion, transparency and Excellent gloss, and excellent ink absorption and high drying. Nano-calcium carbonate is used as ink filler in resin-based ...

AI Technical Summary

Problems solved by technology

[0003] The production process of nano-calcium carbonate generally uses limestone as raw material, and is prepared through processes such as calcination, digestion, carbonization, separation, drying, crushing, and packaging. The drying and crushing steps are divided into two steps, and the dried nano-calcium carbonate will condense blocks need to be manually transported to the crushing device for crushing, the process efficiency is low, occupying labor costs, the drying equipment and crushing equipment are large in size, occupying a large working space
