The low temperature pulverizer is one of the pulverizer. Many people are not so much in this crushing machine, and it is also very curious. Let's introduce you in detail, hoping to help Everyone. Jet Mill makes a complete set of crushing systems. After the compressed air is dried, it is sprayed into the pulverizing chamber by the Lavar nozzle, and the material is repeatedly collided with the intersection of the multi-high pressure airflow.
The crushing material is pulverized after the fan pulling force Airflow movement to the grading area, under the power of high-speed rotation, the thick centrifugal force generated by the high-speed rotation, the fine particles that meet the particle size requirements are collected by the grading wheel into the cyclone and the dust collector, and the crude particles drops to the pulverizing region to continue pulverization.
Air flow milling is compressed by the Raval nozzle accelerates the supersonic gas stream, and the injection zone is brought into the pulverization region to cause the material to be fluidized (the airflow expansion is suspended, and therefore, each particle has the same motion state). .
Actually, low temperature pulverization is to freeze the liquid nitrogen, so that the waste rubber product is cooled to the glass transition temperature and then pulverized with a hammer pulverizer or roller pulverizer. Its pulverization method has two:
(L) Direct cold freeze low temperature pulverization method. The production process of this pulverization method is to cut the bead portion of the tire on the tire dissection, while dividing the tread into 2 first small pieces, placed in a frozen (liquid nitrogen) device, and then hammer or roller The crusher is pulverized to obtain a rubber powder.
(2) Low-temperature pulverization method is crushed and fine under freezing conditions. The production process of this pulverization method is to cut the waste tire after the (L) method is placed in the freezer, and the hammer or roller mill is crushed, and then frozen again, then fine, thus getting the glue. pink. This production method is highly produced by two liquid nitrogen, so there is a high production cost.
However, when the method is treated with a mid-lunch tire, the wire is easily separated and the power consumption can be reduced accordingly.
