Tungsten powder special airflow crushing classifier

Physical characteristics:

Tungsten powder is a metallic gray - black metal (body - centered cubic crystal). Melting point is 3400 ℃. The boiling point of 5555 ℃. Tungsten is the hardest of all metals.

Application features:

Pure tungsten powder can be made into wire, rod, tube, plate and other processing materials and certain shape products. Tungsten powder mixed with other metal powder can be made into various tungsten alloys, such as tungsten-molybdenum alloy, tungsten-rhenium alloy, tungsten-copper alloy and high-density tungsten alloy. Another important application of tungsten powder is to make tungsten carbide powder, and then to prepare cemented carbide tools, such as turning tools, milling cutters, drill bits and moulds.

Equipment selection:

Tungsten powder is the main raw material for powder metallurgy tungsten products and tungsten alloys. Tungsten hardness is the hardest metal, so the use of ZJ series airflow crushing classifier, airflow crushing classifier is based on the physical characteristics of superhard materials and processing requirements, developed a special for superhard superfine materials crushing classification equipment. According to the customer's requirements for ultra-fine grinding and grading treatment.

Working principle:

ZJ series airflow crusher USES several relatively arranged nozzles to form high-speed airflow, and then USES high-speed airflow to accelerate materials to supersonic speed and make them 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 than 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.

Equipment composition:

ZJ series diamond special 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, no water, washing, completely dry production, can get a narrower particle size distribution, non-polluting abrasive powder; Primary crushing classification can be processed into any brand according to the current standards at home and abroad (such as: national standard W63 ~ W3.5, Japanese standard 240# ~ 3000# and European standard f230/53 ~ f1200/3). Single number yield reached more than 75%.

2. High grading accuracy, more accurate cutting particle size, lower required speed and long service life.

3, independent casting bearing, never deformation, long service life.

4, optimized transmission design, bearing force is small, long service life.

5, unique pipeline design, help powder flow, help reduce wear, easy to wear parts easy to replace and deal with.

6. The company's unique variable frequency feeding system is conducive to the dispersion of materials, the continuous, uniform and stable feeding, and the control of product particle size.

7. Unique design of internal circulation secondary air, adjustable clearance of grading cone, greatly reduced gas consumption, reduced energy consumption of grading, and thorough extraction of fine powder.

8, the separation of the flow path, help to reduce the bottom of the grading wheel wear, and more conducive to the control of large particles.

9, completely closed negative pressure operation, no dust pollution.

10, good stability, a fixed parameter adjustment, stable production;

11. In particular, the core competitive advantage of more thorough extraction and better stability of fine powder has been widely recognized in the industry.

Scope of application:

This series of crushing classifier with its unique working principle can be dry, high purity, low temperature processing various materials such as super fine powder, widely used in chemical, mining, abrasive, battery materials, refractory materials, non-metallic mineral, metallurgy, building materials, pharmaceuticals, food, pesticides, feed, new materials, environmental protection and other industries and dispersion of ultrafine crushing, all kinds of dry powder materials and plastic particles.
