Problems solved by technology

This system has a low crushing efficiency for materials with high hardness and toughness values, and is labor-intensive and time-consuming, especially when it is crushed to particles with a diameter of 0.87 microns, aerosol phenomenon will occur, that is, an electrostatic aerosol layer is generated on the surface of moissanite, which can no longer Continue to be crushed, which directly restricts the production capacity of enterprises and the in-depth development of products

Embodiment Construction

[0015] The preparation method of moissanite granular material according to the present invention is mainly prepared according to the steps of "hammer crusher pulverization → ball mill pulverization → steam flow medium pulverization classification → moisture classification and impurity removal → filter press dehydration → drying and packaging" to prepare 0.5μm moissanite particles.

[0016] The specific preparation steps are described below with specific examples, including:

[0017] In the first step, put the artificially synthesized moissanite crystal columnar block (diameter 28mm, height 50mm) into the hammer crusher for crushing, set the feed rate of the hammer crusher to 300kg / h, and screen through the hammer crusher filter Take out 1-3mm pellets and put them into bin 1 (see figure 1 ).

[0018] In the second step, at a feed rate of 1200kg / h, the granular material in the bin 1 is transferred to the computer-controlled superhard material horizontal ball mill 2.1 for grind...

Abstract

The invention discloses a preparation method of a moissanite blade material. The preparation of a moissanite particle material with a diameter of 0.45-0.5 [mu]m is mainly carried out according to thesteps of ''hammer crusher crushing -> ball mill crushing -> steam flow medium crushing and grading -> moisture grading and impurity removal -> pressure filtration dewatering -> drying and packaging''.When the material is in an jet mill, the high temperature and high pressure water vapor and the silicon carbide medium balls work together, so that the collision speed of logistics is accelerated, the shortage of logistics vectors is avoided, the electrostatic aerosol layer generated on the surface of moissanite during the crushing process is effectively removed, and moissanite is crushed into ultra-fine micro-powders with a median particle size of 0.6 [mu]m. According to the preparation method, the crushing effect on the silicon carbide raw material is good, and the crushing efficiency is high, so that the method is beneficial to the deep processing production of moissanite, and new functions of the product can be further developed.

Description

technical field [0001] The invention relates to mineral raw material moissanite, in particular to a preparation method of moissanite cutting material. Background technique [0002] Moissanite is a relatively rare mineral raw material. Natural moissanite is widely distributed in various rocks and minerals from igneous rocks to sedimentary rocks, from meteorites to stone rocks, from diamonds to bauxite. Moissanite has superior toughness and high hardness (Vickers hardness above 4000, slightly lower than diamond, but higher than silicon carbide and boron carbide), used to make moissanite ceramics, electronic ceramics, etc., generally need to crush the raw material After the blade is made, it is further processed. At present, the production of moissanite blades all use compressed air as the air source of the jet milling and grading system. This system has a low crushing efficiency for materials with high hardness and toughness values, and is labor-intensive and time-consuming...
