The full protective ceramic liner airflow pulverization charter has the following performance advantages: dry pulverization of various materials suitable for the Moh's hardness 9 or less, is particularly suitable for high hardness, high purity, and high value-added materials. The breakthrough of particle acceleration technology has greatly improved pulverization efficiency, reduced energy consumption, small pulverization, good particle shape, and no large particle size and no large particles, and the product particle size D97 = 3-74 microns were arbitrarily adjusted. During the pulverization, due to the sharp expansion of the airflow, the airflow temperature is lowered, especially suitable for the heat sensitive, low melting point and the volatile material. The material collides with each other, which is different from mechanical pulverization relies on the impact of the material or a hammer, and plus all-round ceramic liner, so the equipment is small, and the product is purity. It can be used in series with multi-stage airflow classifiers, and products producing multiple particle size sections at a time. The ceramic liner is pulverized, the equipment is compact, the disassembly and cleaning is convenient, and the inner wall is smooth without dead angles. The entire system is fully negatively pressed, no dust, low noise, clean environmental protection.
using nitrogen gas stream pulverizing classifier, mainly isolated from the air with nitrogen, pulverized and classified some of the easily oxidized at ordinary temperature, explosive materials, such as cobalt powder, tungsten powder, iron powder, titanium compound fine spherical aluminum powder, NdFeB, carbonyl iron powder, a nitride, boron carbide, magnetic materials, nickel powder, tantalum powder, drying powder related materials, nitrogen jet milling classifier can be broken up, sieved to these raw materials, pulverizing Wait.
Principles of explosion nitrogen jet milling classifier by employing nitrogen as the grinding media, the system from the feed, pulverization, classification, conveying, separating and packaging the whole of the material during both the Under nitrogen protection. In positive pressure closed system oxygen analyzer by automatic line detection and oxygenating means for controlling the oxygen content within the safety standards, the oxygen content in the mixture of nitrogen and dust is reduced to a value not propagate the flame; reduce the oxygen content at the same time increases the ignition temperature of the dust cloud, ignition energy and lower explosive limit, so that the ignition temperature of the dust cloud, down ignition capability. When the volume fraction of the oxygen is at a certain limit, the dust cloud cannot explode regardless of the dust cloud concentration. This value is called the ultimate oxygen content of the dust. In practical applications, a certain safety factor is often taken to the ultimate oxygen content to give the maximum allowable oxygen content. According to different materials, nitrogen can be replaced with gas such as argon, helium, carbon dioxide. In view of the systemThe equipment and pipelines are metal components, and the dust collector is a conductive filler bag, and the whole system is well grounded to try to release powder static electricity. The whole system uses explosion-proof motor, electrical appliances and explosion-proof structures to ensure safe operation.
Summarizing the nitrogen protection airflow pulverization grading machine has the following advantages:
1, the applicability is strong. Suitable for flammable and explosive material is easily oxidized and pulverized by the material of oxygen isolation.
2, inert gas circulation, consume very small.
3, the equipment wear is small, and the material is pulverized between the materials and reduces the wear of the equipment cavity.
4, the pulverized granular granularity range is wide in the range of D98 = 1 to 74um.
5, using the PLC controller, fully automatic control, easy to operate.
