1. pulverization process Single cycle pulverization process This process can use a hammer mill with enlarged sieve holes and a plane rotary screen or a vibrating grading screen. After being crushed, the materials are retained on the sieve holes through a grading sieve, and then transported back to the original crusher for pulverization, and the under sieve can directly enter the batching bin. It uses the method of enlarging the sieve hole to increase the material flow rate, thereby reducing energy consumption. This process saves 26% ~40% of electricity compared to the secondary crushing process. Increase production by 34% ~ 50%. Secondary crushing process This process can use two hammer mills or a combined process of roller mills and hammer mills. The materials are usually classified after being coarsely crushed by the first crusher. The coarse particles are crushed again by the hammer mill. This process can eliminate the impact of material reflux on the efficiency of the pulverizer in a single cycle process. In combination with the roller mill, the excellent characteristics of the roller mill can be fully utilized, which not only saves power consumption, but also reduces noise and makes it easy to adjust the fineness of the product. This process can achieve the same process effect as a single cycle process.
2, the transportation of crushed materials The transportation of crushed materials adopts mechanical transportation ([plus suction).
After the secondary crushing process is adopted, the particle size of the product is correspondingly increased, and the output of the crusher is large. After crushing, the lifting equipment and the horizontal conveying equipment must have the corresponding conveying capacity.
3. When using the automatic control feeder shredder to work under the best conditions. It is required to feed uniformly under the maximum workload, so that the grinder can work efficiently and stably. Using the automatic control feeder can adjust the feeding speed according to the material moisture, characteristics, fiber and other stars, so that the motor current can run efficiently under the rated load. Because the feeder achieves the best load control on the crusher, the power consumption of the feed mill is reduced, and the output of the crusher is increased.
4, the use of a new type of crusher vertical shaft crusher has been used in European feed mills in recent years, and compared with the horizontal hammer mill. More and more show its obvious superiority. The vertical shaft mill eliminates the auxiliary suction system. This solves the problem of low efficiency caused by improperly equipped suction system and failure of the suction system in the traditional process, and reduces water loss. The machine is also equipped with a quick screen change system, multi-port feeding, and quick hammer loading and unloading mechanism. The machine is also equipped with a temperature sensor and a vibration sensor. Monitor the working condition of the shredder. The use of a vertical shaft grinder can increase the output by more than 25% and save energy by more than 30%, which is more and more popular with users. There are many factors that affect the crushing efficiency. Full consideration in the selection of equipment and the determination of the process layout is an important way to improve the quality and efficiency of crushing.
