Embodiment Construction

[0017] The crushing device for beryllium coarse powder of the present invention comprises a disc mill 1, a gravity classifier 2 and a cyclone classifier 3 connected together in sequence, wherein the disc mill 1 includes a conical shell and a fixed fixed device installed in the conical shell. Disk 5 and moving disk 6, fixed disk 5 and moving disk 6 are two grindstones of equal size, fixed disk 5 is also called stator, and moving disk 6 is also called rotor, and is made of cemented carbide. The stator and rotor are aligned in parallel, beryllium shavings or powder pass through the stator and rotor, and are ground into powders that meet the requirements under the high-speed rotation of the rotor. The upper end of the conical shell is connected with an air intake system (specifically connected through the air inlet opened at the upper end of the conical shell). When the wind force is constant, the grinding rate can be controlled by controlling the current. A cold water circulation...

Abstract

The invention relates to a beryllium coarse powder crushing device and a production method for beryllium coarse powder using same. The beryllium coarse powder crushing device comprises a disc mill, a gravity classifier and a cyclone classifier which are sequentially connected; the disc mill comprises a cone-shaped casing, a fixing disc and a moving disc; the fixing disc and the moving disc are arranged inside the cone-shaped casing. According to the beryllium coarse powder crushing device, the disc mill which is provided with the fixing disc and the moving disc is used, beryllium scraps or powders are milled into powder satisfying requirements due to high speed revolution of the moving disc, classification is performed sequentially through the gravity classifier and the cyclone classifier, finally coarse powder with the grain diameter of 30 to 10 microns is obtained, and pure beryllium powder is obtained through impact milling to be provided for beryllium materials of different sizes. The production method for the beryllium coarse powder using the beryllium coarse powder crushing device is simple in technology, short in period and enables 1 to 10 kg beryllium coarse powder to be obtained per hour.

Description

technical field [0001] The invention relates to the technical field of nonferrous metal production, in particular to a crushing device for beryllium coarse powder and a method for preparing beryllium coarse powder by using the crushing device. Background technique [0002] The performance of beryllium powder is a key factor in the production and processing of beryllium materials. Due to the particularity of beryllium (toxic, hard and brittle), the requirements for the material and sealing of the equipment are very high. At present, there is no equipment suitable for crushing beryllium materials in the market. Contents of the invention [0003] The object of the present invention is to provide a crushing device for beryllium coarse powder suitable for beryllium material crushing. [0004] Another object of the present invention is to provide a method for preparing coarse beryllium powder using the crushing device. [0005] The technical scheme adopted for realizing the a...
