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

Abstract

The invention discloses an inert gas protection and on-line detection ultra-fine crushing system. The inert gas is pressurized to 0.8-1.0 MPa and then enters the crushing main engine. Raw materials are fed into the crushing main engine from the silo for crushing, and after crushing, they flow to the cyclone separator and catcher, and collected into the first and second finished product barrels. The filtered inert gas is returned to the suction port of the compressor. The inert gas source and gas storage tank are connected to the return gas pipeline of the system, and the high purity of the inert gas in the system is maintained by supplementing the gas. The pipeline connected with the host and the cyclone separator is equipped with an online sampler. The sample taken out passes through the laser detector and then returns to the cyclone separator in the crushing system. After the signal is collected by the laser detector, it is sent to the online system control computer for statistical analysis, and the The particle size signal is sent to the main control computer of the system, and the main control computer automatically adjusts the crushing process parameters to the optimal value after comparing the current particle size with the preset target particle size.

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
