Environment-friendly type non-metal super fine powder processing technique and equipment

Abstract

The invention discloses a processing technique and device for environment-friendly nonmetal micropowder, comprising: a treating raw mine by loading wet method, high pressure water forming large water curtain to prevent the powder from being discharged outside when primary crushing the raw mine; b adding new technique to the grinding device and five more dust collecting devices on each measuring means and production bucket, and adding host computer fan closed-loop system to prevent the powder outside during the baiting and grinding process; c sending the end product in the dust collecting device to product barrel using a dense phase gas conveying system and packaging the end product using automatic packing machine. The said technique and device are suitable for production of nonmetal micropowder, such as calcium carbonate superfine powder, talcum powder, barium sulphate, in order to prevent the powder from being discharged outside, with good popularization value.

Description

technical field [0001] The invention relates to the technical field of non-metal ultrafine powder processing, and more specifically relates to a production and preparation process and equipment for ultrafine calcium carbonate (talcum powder, barium sulfate). Background technique [0002] At present, the equipment used in the manufacture of ultra-fine fillers is vertical mill, jet mill, ball mill, vibratory mill, etc. The production process is generally a positive pressure method in which the finished product is collected by wind, which results in a large amount of dust in the production site and a harsh environment, especially It is an occupational disease of dust, which seriously affects the development of enterprises and the physical and mental health of employees. Therefore, dust leakage and backward technology are issues that must be overcome by my country's ultrafine powder. Contents of the invention [0003] The purpose of the present invention is to provide an enviro...

Problems solved by technology

[0002] At present, the equipment used in the manufacture of ultra-fine fillers is vertical mill, jet mill, ball mill, vibratory mill, etc. The production process is generally a positive pressure method in which the finished product is collected by wind, which results in a large amount of dust on the production site and a harsh environment, especially It is an occupational disease of dust, which seriously affects the development of enterprises and the physical and mental health of employees. Therefore, dust leakage and backward technology are issues that must be overcome for ultrafine powder in our country.
