Super-micro gas flow grinding is a huge contribution to human crushing, many families and companies have helped, solve the problem of pulverizing daily, with the development of pulverizer, ultra-microcarrier development, make more companies Further get rid of hard work and can borrow machines to replace manual and make more efficient and better effect.
It is well known that during the processing of minerals, ultrafine powder product performance and the processing process used by the processing process, the formulated operation procedures are indispensable. The process of use, the processing equipment used, and the working procedures are different, and different mineral utilization, different production costs, different product quality, and different economic benefits.
The basic working principle of the airflow pulverizer (disc, the spray, sulfur bed, and ⋯) is to use high pressure gas to carry the mineral particles in the pulverized cavity, and friction, etc. to achieve a pulverization. The working principle determines the particle size, material hardness, airflow speed, collision mode, discharge particle size limit, etc., which determines the grinding efficiency and product quality. Since the broken momentum is used as a gas, the energy utilization rate is greatly reduced. Compressing the air of the natural state is compressed, converting the energy or chemical energy (engine) into the energy of the compressed gas, impurities (oil, water, water, etc.), enters the pulverizing cavity release energy, and the subsequent gas energy Unable to recycle. These processes cause the energy utilization rate of the equipment to be quite low. High-pressure gas carrying the processed mineral particles in a pulverized cavity, a severe collision, friction, etc., so that the breaking ratio is not too large, even if a very high air pressure is applied, the effect will not change significantly. This causes the preparation of the gas flow crushed granularity to be invested, and the pollution is usually produced here. The airflow pulverizer is small in size, and can be processed using a price and expensive non-metallic material to avoid contamination of materials when crushing, so the airflow pulverizer host can process ultrafine powder products with high purity. The pollution generated by the airflow pulverizer is from the previous process. The granular sphere of the collision produced is poor.
The basic working principle of Raymond (vertex, roll mill, pulling, ...) is to use rolling force, see Figure 1 (b). Whether it is a rolling installation method, a lead straight arrangement, an inclination arrangement, or the like, or the rolling roll assisted in mechanical or hydraulic forms of pressure to improve crushing.There are two problems. One is a bite angle formed between the rolling and the support disk, determines the incident particle size of the crushed material to be clamped by the friction. Exceeding the particle size of the bite angle, regardless of how much pressure is applied, not only cannot crush the material, but will increase the crush phenomenon caused by the rolling of material accumulation wave and the rolling jump. The second is that with the refinement of the material, the number of material particles on the rolling roll under the contact surface increases, and the crushing force of a single material particles is drastically reduced, which greatly reduces the processing capacity of the equipment. Rolling rolls excessively pressure, giving the material selection of Raymond grinding components, reasonable application of dynamic performance and energy consumption brought difficult experience. Raymond (vertex, roll grinding, mill mill, ...) work system is subject to work mode, and impurities that remove processing incorporation becomes extremely difficult. Because it is difficult to manufacture rolling parts with large volumes of non-metallic materials, the amount of impurities is large and difficult to remove. The grading needs another additional system and equipment.
The basic working principle of high-speed impact grinding (hammer, fan type, ...) is to use the high-speed impact of the equipment and break the material through the second impact of the counters. With vigorous collision, friction, etc., this will reduce the crushing capacity with the refinement of materials. Moreover, the gap between the rotor and the stator changes due to wear, resulting in amplification of the crushing particle size. The speed of the rotor is conducive to breaking to obtain more material particles, but the rotor kinetic problem gives a lot of trouble to manufacture and use, and materials with large processing hardness become difficult. Impact collisions have been obtained from product spheres and fluidity. Similarly, the material of the working system is limited by the working mode, which is difficult to use large-volume non-metallic materials to make impact parts, and the impurities that remove the process incorporation becomes extremely difficult.
Treatment of non-metallic minerals in actual production should try to study and adopt a reasonable optimized process process, and propose and determine the performance requirements of mechanical equipment by optimized process process, provided by equipment manufacturers. Can fully meet the equipment required by the process. This customized non-standard device is optimal product performance and economic benefits. Although investment costs have increased slightly, the total benefits are far exceeding the results of equipment selection. Take a step, for the factory-oriented equipment should be proposed to meet the requirements of its own requirements, not to easily change the process requirements to accommodate the performance of the established equipment. according toProcess optimization parameters, allowing manufacturers to provide complete sets of equipment is the best choice, so you can get the best working status and its high-quality products, you should first insist on this.
