Classification, principle and characteristics of jet mill

What are the classifications of jet mills? The jet mills used in my country's industry mainly include the following types: spiral jet mills, fluidized bed counter-jet jet mills, circulating tube jet mills, and counter-jet jet mills Machine, target type jet mill. Among these types of jet mills, flat jet mills and fluidized bed counter-jet jet mills are widely used. What are the working principles and characteristics of the jet mill? 1. Working principle: The working principle of the jet mill is: compressed air is dried, and after drying, it enters the crushing chamber through the nozzle. In the crushing chamber, the high-pressure airflow enables the material to be crushed. Afterwards, the coarse and fine materials can be separated under the centrifugal force generated by the grading turbine. The particles that meet the particle size requirements enter the cyclone separator and dust collector and are collected, while the particles that do not meet the requirements continue to be crushed. 2. Performance characteristics: The performance characteristics of the jet mill are mainly as follows: (1) There is a vertical grading device inside, which can adjust the particle size of the product, and the pulverization particle size is good, and the particle size distribution is relatively narrow. (2) It can be used in series with a multi-stage classifier, so that multiple granularity sections can be formed at the same time. (3) The equipment is very convenient to disassemble and assemble, and it is easy to clean. There is no dead corner on the inner wall, so it can be cleaned thoroughly. (4) The operation is airtight, which makes the operation noise low, reduces the generation of dust, and is environmentally friendly. (5) The control system is easy to operate, and the equipment runs safely and reliably.
