1 On the basis of ultrafine pulverization method of the existing ball mill, improve ultrafine pulverization (grain material material to particle diameter is micron-stage operation) ultrafine pulverization force, particle size distribution , Granular crystalline type adjustment control (Control) technology. The ball mill can be divided into a short cylinder mill, a long cylinder mill, a tube mill, and a conical mill. The ball mill is one of the high fine mills widely used in industrial production, and there are many types. The ball mill differs depending on the mine mode, can be laminated and overflow type.
2 The existing mechanical ball mill crusher equipment process is common: environmental pollution, material waste. The ball mill differs depending on the mine mode, can be laminated and overflow type. How to solve many problems with many problems in the mechanical pulverization machines, the ultra-microfinner enterprises jointly develop, and the technical direction is overcome. Provide customers with high efficiency (effection) efficiency, low price cost, small limit particle size, high particle size controllability and good dispersibility, secondary pollution small advanced ultrafine pulverized equipment classification equipment.
3 Existing Domestic Ball Mill Ultrafine Crusher Performance (Function) Detection (Check and Test) Standard Evaluation Method is not uniform, ultra-smuggler equipment enterprises should unify industry standards to provide users with real and effective reference standards.
4 ball mill ultrafine pulverizer application new industry modern industry: function ceramics (raw materials: non-metallic minerals), catalytic materials, coating materials, electronic information materials, energy environmental protection, biopharmaceutical, organic / inorganic composites, etc.
5 Mechanical ball mill pulverization method Preparation of ultrafine powder main methods. Currently used in the preparation of ultrafine powder equipment, main: ball mill, drum ball mill, vibration grinding, grinding micro-powder machine, sandy ultra-microscope, planetary ball grinder, colloid (COLLOID) mill, gas flow grinding. Using the above pulverized apparatus to reach the D98 particle size uniform (jūn yún) controllable must have a good classification device, and must be fine. Since the product particle size is fine, the gravity grading takes time, and the centrifugal power field is generally used.
6 Mechanical ball mill pulverization and grading principle: 1. Solid material pulverizer achieves a pulverizer effect due to mechanical force. The ball mill can be divided into a short cylinder mill, a long cylinder mill, a tube mill, and a conical mill. This ultrafine pulverizer can generally be divided into extrusion, impact, shear, friction, etc. Ultrafine pulverized equipment has a role (air current pulverizer), as well as composite force (abrasive microfin machine, colloid mill). The force pulverization effect is preferably shearing friction, and the intensity distribution is narrow, and the effect is ideal. The extrusion impact is the worst. 2. Only in the current technologies, the mechanical ultrafine pulverizer with air as a hierarchical medium (substance determined by determining) can only reach the ultra-fine pulverizer requirements. Only by water other liquids are classified as a hierarchical medium (maybe) Implement ultrafine pulverization separation classification. Because the ultrafine powder gravity settlement speedToo small, the settlement time is too long, and it is also affected by microparticles (content: atom, molecules, ion) diffusion movement, industrial production is difficult to achieve, only the centrifugal power field can effectively overcome the influence of particulate diffusion motion and shorten settlement.
