The spice grinder should be a relatively high-precision facility. In the usual application and maintenance process, some key points still need to be paid attention to by the control staff. In order to improve the crushing rate of the spice grinder, it is necessary to check whether the raw materials meet the regulations before manufacturing. , Doping impurities in raw materials is prohibited. During manufacture, a corresponding amount of material must be maintained in the grinding chamber of the spice grinder. In the case of the same crushing gas pressure, there is a lot of material in the grinding chamber, and the current of the screening machine is large; there is less material in the grinding chamber, and the current of the screening machine is small. At the same time, the feeding rate must be balanced and stable, not too fast or too slow. If the feed rate is too fast, the facility will be overloaded. It is also necessary to maintain the facility on time. Always check whether the steam supply burden is the burden required for crushing, and the classification motor of the spice grinder. After the facility has been running for 3,000 hours, or before it is used again after long-term shutdown and long-term storage, please Immediately remove the material adhering to the nozzle of the spice grinder, the inside of the grinding chamber and the material adhering to the classification part to avoid disturbing the crushing effect of the spice grinder.

The adjustment of the final particle size of the product by the spice grinder mainly depends on the particle size of the raw material, the crushing burden, the feeding burden, and the feeding rate. The logical connection between the spice grinder and these data is mainly: the smaller the particle size of the raw material, the higher the crushing rate, on the contrary, the larger the particle size of the raw material, the lower the crushing efficiency. When the crushing burden and the feeding burden are corresponding, the product will be finer if the feeding rate is reduced, and the product will be thicker if the feeding rate is increased. In the case of the corresponding feeding rate, the particle size of the commodity will be finer if the crushing burden is increased, the crushing burden will be reduced, and the commodity will become coarser.

Therefore, particle size adjustment depends on the adjustment of the spice crusher in the crushing process to achieve different crushing particle sizes. Before crushing, it is necessary to check the relationship between the feeding efficiency and the burden, and then clarify the appropriate crushing data to meet the user's particle size requirements. Finally, the particle size of the product needs to be checked and classified by a particle size detector. The classification can be more accurate if it is inspected with an electron microscope. Naturally, the inspection results can be compared with the internationally renowned particle size detector.
