Barite modifying and crushing assembly and production device

Abstract

The invention discloses a barite modifying and crushing assembly and a production device, and belongs to the field of barite processing. The assembly comprises a crushing chamber, a rotating disc, an air compressor, a modifying agent hopper and a drive device. The crushing chamber is provided with a crushing cavity. An air inlet and a modifying agent feeding inlet are formed in the bottom end of the side wall of the crushing chamber. The air compressor communicates with the air inlet. The modifying agent hopper comprises a conveying tube connected with the modifying agent feeding inlet and a hopper body connected with the conveying tube. The hopper body is provided with a sealing cover. A first regulating valve is arranged between the hopper body and the conveying tube. A second regulating valve is arranged between the conveying tube and the modifying agent feeding inlet. The rotating disc is arranged at the bottom of the crushing cavity and comprises a disc body and a plurality of propeller blades. The disc body is rotationally connected with the drive device. The propeller blades are uniformly distributed at the top of the disc body. The device comprises a barite screening assembly and the barite modifying and crushing assembly. A discharging outlet communicating with the crushing cavity is formed in the top of the crushing chamber. The barite screening assembly is arranged at the discharging outlet. The crushing efficiency is high, modifying can be performed, the process is saved, the product particle diameter is small, the product purity is high, and equipment loss is small.

Description

technical field [0001] The invention relates to the field of barite processing, in particular to a barite modified crushing component and a production device. Background technique [0002] Barite is a very important non-metallic mineral raw material and has a wide range of industrial uses. It is mainly used in drilling mud weighting agent, lithopone, various barium compounds, mineralizers for cement industry, and radiation-resistant cement. Mortar concrete and road construction and other fields. Barite has a large demand in various industries. Due to the different requirements for the particle size and surface properties of barite when used in different fields, it is necessary to grind and crush barite during the processing of barite. Surface modification and other operations to make barite meet the requirements of use. [0003] In the prior art, the grinding parts of the grinding mechanism are usually used to grind and impact the barite, which has problems such as low cru...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the grinding parts of the grinding mechanism are usually used to grind and impact the barite, which has problems such as low crushing efficiency, excessive product size, large equipment loss, and high product impurity content.

In addition, the modification of barite usually needs to be wrapped by adsorption after grinding and crushing, which is troublesome to operate
