Development trend of ultrafine pulverization technology of ball mill

　　On the basis of ultrafine pulverization method of the present ball mill, improve ultrafine pulverization (grinding the powder material to the particle size of the particle diameter) ultrafine pulverization, particle size distribution, granular crystalline type adjustment 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 is different from the mineral mode, can be laminated and overflow type.

　　2 The existing mechanical ball mill crusher equipment technology is generally phenomenon: environmental pollution, material waste. The ball mill is different from the mineral mode, can be laminated and overflow type.

　　How to solve the development of many problems in many problems in the mechanical pulverization machine, and the technical direction of the company. Provide customers with high cost, low price cost, small limit particle size, good particle size control, and good dispersibility, secondary pollution small advanced ultrafine pulverized equipment classification equipment.

　　3 Existing domestic ball mill ultrafine pulverizer performance (inspection and test) standard evaluation method is not uniform, ultra-smash equipment enterprises should have a real-effective reference standard for users 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 Main method of ultrafine powder in ultrafine powder in mechanical ball mill pulverization. Currently used to prepare ultrafine powder equipment, main: ball mill, drum ball mill, vibration grinding, grinding micro-powder machine, sand mill ultrasound, planetary ball mill, colloid, gas, 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 crushing method and grading principle:

　　1. Solid material pulverizer is due to mechanical effects to achieve a pulverizer. 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 uses a role (air current pulverizer),There is a composite force (grinding fine powder machine, colloid mill). The force of the action is preferably shearing friction, and the intensity distribution is narrow, and the effect is ideal. The extrusion impact is the worst.

　　2. As far as is currently technically, the mechanical ultrafine pulverizer can only reach the ultra-fine pulverizer requirements with air as a grading medium (substance to determine the effect), and only the other liquids are centrifugated as a hierarchical medium. (Maybe) Implement ultrafine pulverization separation classification.

　　Because the ultra-fine powder gravity is too small, the settling 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 impact of particulate diffusion motion , Shortening settling.
