Inert gas protection and on-line detecting ultra-fine comminuting system

Abstract

The present invention discloses an inert-gas protection and online detection super fine smashing system, with the technics as follows: the inertia gas is pressurized to 0.8 to 1.0 MPa and transported into the main smashing machine, the raw material fed into the main smashing machine through a hopper flows to a whirlwind separator and a disposal device on the rear after mashed, and then collected into a first and a second final product barrel. The filtrated inertia gas flows back to the air inlet of the compressor. The source of the inert gas and the air storage tank are connected with backflow pipes, to keep the high purity of inert gas in the system through providing the gas. Online sampling devices are arranged on pipes connected with both the main machine and the whirlwind separator, wherein the taken samples pass through a laser detector and return to the whirlwind separator in the smashing system, and the laser detector collects and then transmits the signals to a controlling computer of the online system for statistical analysis, and transmits the signal of granularity to a main controlling computer of the system, the main controlling computer automatically adjusts the parameters of the smashing technics to the best value after comparing the granularity at present with the preset target granularity.

Description

technical field [0001] The invention relates to an inert gas protection material crushing device. Background technique [0002] At present, there are many crushing equipments that adopt the airflow principle to crush, but the current situation is: [0003] First: It can only crush conventional products, and it is still difficult to crush those toxic materials, easily oxidized, flammable, and explosive materials; [0004] Second: To crush a new material, from the beginning of trial crushing to normal and stable production, it needs to go through repeated sampling tests and process parameter adjustments, all of which require manual participation; [0005] Third: In crushing, the particle size of the product can only be known by manual sampling and testing on a special laboratory particle size analyzer, and it is time-consuming and laborious. Once the product quality is out of tolerance, there are already substandard products in the product. Cause a certain batch of products ...

Problems solved by technology

[0005] Third: In crushing, the particle size of the product can only be known by manual sampling and testing on a special laboratory particle size analyzer, and it is time-consuming and laborious. Once the product quality is out of tolerance, there are already substandard products in the product. Cause a certain batch of products to be scrapped or reworked;

[0006] Fourth: During the crushing process, fluctuations in process parameters result in large fluctuations in product particle size and wide product particle size distribution;

[0007] Fifth: The operation automation of the equipment is low, and the requirements for personnel skills are high
