1 Based on the existing ultrafine pulverization method, the ultrafine pulverization ultrafine pulverization strength, particle size distribution and grain type crystal shape adjustment control technology are improved.
2 The common phenomenon in the existing mechanical crusher equipment process: environmental pollution, material waste. How to solve the problem of improving the mechanical pulverizer: The micro-grinder company jointly researches and develops and overcomes the technical direction. To provide customers with advanced production equipment with high production efficiency, low price, small size, good controllability and dispersion of particle size, and small secondary pollution.
3 The existing domestic superfine pulverizer performance testing standard evaluation methods are not uniform, and the ultrafine pulverizing equipment enterprises should unify the industry standards and provide users with real and effective reference standards.
4 ultra-fine pulverizer machine application new industry modern industry: functional ceramics, catalytic materials, coating materials, electronic information materials, energy and environmental protection, biomedicine, organic / inorganic composite materials.
5 The main method for preparing ultrafine powder ultrafine powder by mechanical pulverization method. At present, it is mainly used for preparing ultra-fine powder equipment: ball mill, rotary ball mill, vibration mill, grinding micro-powder, sanding ultra-fine mill, planetary ball mill, colloid mill, jet mill. Use the above pulverizing equipment to achieve D98 uniformity and controllable. There must be a good grading equipment, which must be finely graded. Due to the fine particle size of the product, gravity grading takes a long time, and the centrifugal force field is generally used for classification.
6 mechanical pulverization method and classification principle: 1. The solid material pulverizer achieves the effect of the pulverizer due to the mechanical force. The role of this ultrafine pulverizer can be generally divided into extrusion, impact, shearing, friction and the like. The ultrafine grinding equipment uses a force (air jet mill) and a composite force (grinding powder machine, colloid mill). The force pulverization effect is good for shearing friction, resulting in a narrow force distribution and an ideal effect. And the crush shock zui is poor. 2. As far as the current technology is concerned, the mechanical superfine pulverizer with air as the grading medium can only meet the requirements of the ultrafine pulverizer. Only the other liquid liquid as the grading medium centrifugal force grading equipment can realize the ultrafine pulverization separation and classification. Because the final velocity of the ultrafine powder body weight is too small, the sedimentation time is too long, and it is also affected by the diffusion of particles. Industrial production is difficult to achieve. Only the centrifugal force field can effectively overcome the influence of particle diffusion motion and shorten the settlement.
In summary, the drug superfine pulverization, food superfine pulverizer, bone superfine pulverizer, biomedical pulverizer, liquid superfine pulverizer, crystal superfine pulverizer, pulverizer application demand is great. R & D equipment enterprise research and development, design to meet the market demand requirements to design quality products.
The overall development trend of ultrafine grinding technology: development of high production efficiency, low cost, product particle size specific surface area, chemical composition, crystal shape, surface morphology, defects, roughness, etc. Good controllability, good dispersion, stable product quality Fine pulverization of ultrafine grinding process and equipment.
