Improved tungsten-molybdenum flour milling machine

Abstract

The invention relates to an improved tungsten-molybdenum flour milling machine which comprises a casing, wherein the casing internally comprises a feeding bin, a grinding bin and a discharging bin sequentially from top to bottom, wherein the feeding bin is connected with a feeding hole; the feeding bin is internally provided with a vibrating sieve; one side of the casing is connected with a motor A for controlling the vibrating sieve; the grinding bin is internally provided with a main shaft which penetrates through the casing; the main shaft is provided with blades; the casing is externally provided with a motor B for driving the main shaft to rotate; the lower side of the discharging bin is connected with a discharging hole; the discharging bin is internally provided with a discharging sieve; the joint of the discharging sieve and the casing is provided with a secondary discharging hole. The improved tungsten-molybdenum flour milling machine has the advantages that by use of rotation of the main shaft, the blades are driven to collide with materials, so as to achieve purposes of pulverizing and grinding, so that grinding is rapid and convenient; the upper half part of the casing is provided with the vibrating sieve which is capable of sieving initial materials, so that the influence of oversized materials on pulverizing and grinding quality is avoided; the discharging sieve at the lower part of the casing can be used for performing secondary sieving on the pulverized and ground materials.

Description

technical field [0001] The invention relates to a pulverizer, in particular to an improved tungsten-molybdenum pulverizer. Background technique [0002] Metal tungsten and molybdenum are in contact with rolls, molds, graphite milk and air at high temperatures, and the surface is easily polluted, oxidized or chattered. Tungsten and molybdenum processing are prone to work hardening during plastic deformation, and cracks or burrs may also occur on the surface, resulting in The tungsten and molybdenum processing material is brittle and difficult to reprocess, which affects the life of tungsten and molybdenum. At this time, it is necessary to recycle the discarded tungsten and molybdenum for crushing and reprocessing. However, in the existing tungsten and molybdenum pulverizer, it is discontinuously broken when it works, Low efficiency Page shredded unevenly. [0003] Therefore, a new technical solution needs to be sought to solve the above problems. Contents of the invention ...
