Molybdenum disulfide special crushing classifier

Material characteristics:

Molybdenum disulfide, the main component of molybdenite. Black solid powder with metallic luster. Chemical formula MoS2, melting point 1185 ℃, the density of 4.80 g/cm3 (14 ℃), mohs hardness is 1.0 ~ 1.5.

Application:

Molybdenum compounds, lubricating additives, friction materials, etc., the main function is to reduce friction at low temperature, high temperature increase friction, burning loss is small, volatile in friction materials; Anti-friction: the particle size of molybdenum disulfide processed by supersonic airflow grinding reaches 325-2500 mesh, the micro-particle hardness is 1-1.5, and the friction coefficient is 0.05-0.1, so it can play an anti-friction role in friction materials.

Equipment selection:

Lead gray glossy powder, synthetic black. High fineness. 450 ℃ sublimation. Soluble in aqua regia and hot concentrated sulfuric acid, insoluble in water and dilute acid. Relative density (d1515)5.06. It's stimulating. , zj-qlm can be selected according to alumina characteristics

Application model:

What ZJ had - QLM series

Working principle:

ZJ series fluidized bed airflow crusher USES several relatively arranged nozzles to form high-speed airflow, and then USES high-speed airflow to accelerate materials to high speed of sound so that they collide with each other at the intersection of nozzles, so as to achieve the purpose of ultra-fine grinding. Crushed material into the classifier classification chamber with the increased flow, due to the grading rotor high-speed rotation, is constrained by the particle grading rotor produced by centrifugal force, and by airflow, and the centrifugal force generated by viscous, when particles by centrifugal force is greater than the centripetal force, the grading size more coarse particle crushing chamber to continue to shock crushing, fine particles with the air flow in cyclone separator, the trap to collect, the gas is removed by induced draft fan.

ZJ series fluidized bed airflow crusher is the replacement of traditional fluidized bed airflow crusher, jet airflow crusher, horizontal airflow crusher and other types of airflow crusher. The best characteristic of this machine is to make full use of jet energy.

Equipment features:

1. Green and environmental protection: low-temperature dielectric grinding ensures high purity and reasonable characteristics of the product. The equipment operates under negative pressure without dust pollution.

2, high efficiency: the full use of jet energy, compared with the traditional airflow mill grinding efficiency of 30%, classification accuracy is higher.

3, equipment wear small: "fluidized bed + vertical classifier" structure can be high purity, ultra-narrow processing of ultrafine powder, avoid the "fluidized bed + horizontal classifier" classification part of the wear, in the same material wearing parts of the service life is 20 times the international similar products. Minimal wear, especially suitable for ultra-fine grinding of high purity and hardness materials.

4. High output: when producing products with narrow particle size distribution, the yield is more than 1 times higher than that of traditional convection jet and fluidized bed airflow crusher.

5, multi-purpose: a multi-purpose machine, can be used as a crusher can also be used as a classifier. The particle size range of grinding is wide, and the particle size can be adjusted in the range of 1-74um at will.

6, intelligent: the equipment can achieve all automatic control, simple operation, stable operation, excellent production environment.

7. Reasonable design: compact structure of the equipment, no material storage, no dead space in the crushing machine, easy to disassemble and wash, disinfect, and convenient to replace crushed materials.

8. The whole system adopts automatic control, which can realize one-key start and stop, simple and convenient operation and connection with central control can realize remote control.

Application:

Widely used in chemical, mineral, metallurgy, abrasive, ceramics, refractory, medicine, pesticides, food, health products, new materials and other industries
