EPIC Powder Machinery in case of failure of the feed system of the superfine jet mill

Ultrafine air jet mill is generally used for grinding dry, high hardness, rare and high added value raw materials. With excellent product quality, it is a kind of equipment favored by many users. The processing flow of the superfine air flow pulverizer includes feeding, crushing, grading, collecting and discharging. The feeding system, as the front-end process, has less chance of failure. However, the phenomenon of feeding jam may occur. Now let's introduce it to you

Simple analysis of the reasons for the large size of the material in the silo of the ultramicro air flow pulverizer, such as the long time accumulation of materials in the silo, the moisture absorption and agglomeration of materials, the bridging of materials in the silo, and the lack of reference for the repose angle of materials in the silo cone angle design. It is recommended to fully understand the properties of materials in the design stage, such as bulk specific gravity, fluidity, moisture absorption, angle of repose, particle size, flammability and explosiveness. Adopt auxiliary blanking measures, such as air disc, air hammer, air blowing, vibrating discharge mechanism, manual tapping, etc. Ultrafine pulverizer is a kind of equipment that uses the form of air separation, heavy pressure grinding and shearing to realize the ultra-fine pulverization of dry materials. The utility model is composed of a cylindrical crushing chamber, a grinding wheel, a grinding rail, a fan, a material collecting system, etc. The material enters the cylindrical crushing chamber through the feeding port, and is crushed by rolling and shearing of the grinding wheel that moves circularly along the grinding rail. The crushed materials are taken out of the crushing chamber by the negative pressure airflow caused by the fan and enter the material collection system. After filtering by the filter bag, the air is discharged, materials and dust are collected and crushed

The feeding system of the ultramicro jet mill is one of the key components, and problems are often encountered in actual use, such as no feeding in the silo, uneven feeding, or even no feeding. The non-uniform feeding element simply analyzes that the material is sticky or has good fluidity, and the feeding system is defective in design. It is suggested to solve the problems systematically according to the material properties, such as the silo structure, auxiliary feeding structure, feeding valve structure, namely auxiliary feeding measures, and induced draft and control system. The feeding system is composed of three parts: general silo, auxiliary blanking equipment and feeding mechanism. The design parameters of the feeding system are different according to the nature of materials

The above are the precautions and simple solutions for the use of EPIC Powder Machinery ultramicro airflow pulverizer. You must pay more attention when using it. Users who want to view the information about the pulverizer can also directly log in to our official website
