Magnesium metal smashing and grading device and technique thereof

Abstract

The invention provides a magnesium metal smashing and grading device and the technique thereof and belongs to the technical field of material smashing. The magnesium metal smashing and grading device comprises a feeding device, a crushing device, an inert gas circulation loop, a primary gas-solid separating device, a wind power driving device, a secondary gas-solid separating device and a dust collector, wherein the feeding device is provided with a material inlet and an inert gas inlet, the dust collector is provide with an inert gas outlet, the inert gas circulation loop sends inert gas separated out from the dust collector into the crushing device through an air-returning pipe, inert gas can be reused, and explosion venting openings are respectively formed in the upper parts of the primary gas-solid separating device, the secondary gas-solid separating device and the dust collector. The magnesium metal smashing and grading device provided by the invention has a novel structure, is reasonable in design, is safe and reliable, and is simple to operate, can achieve crushing, grading and cooling to inflammable, explosive and easily oxidized materials, integrates various functions, and is strong in practicability.

Description

technical field [0001] The invention belongs to the technical field of material crushing, and in particular relates to a metal magnesium crushing and classifying device and a process method thereof. Background technique [0002] Inflammable and explosive materials such as oxidants, combustibles and explosives have important uses in various fields of the national economy and in the military. With the development of science and technology, higher and higher requirements are put forward for the performance of these materials, the most typical of which is to require ultra-fine processing of these materials, because the performance of these materials can be obtained after ultra-fine processing. Great improvement. Because flammable and explosive materials are usually easy to decompose, have a low ignition point, and are extremely sensitive to heat, temperature, impact, friction, static electricity, and sparks, it is very difficult to make them ultra-fine in terms of technology an...

Problems solved by technology

This invention can reduce the temperature of the material pulverized by the ultrafine pulverizer, but its consumption of liquid nitrogen is large, and its function is single, so it cannot classify and separate the material
