Special crushing classifier for petroleum coke

Performance characteristics:

Vacuum residuum oil, the coking unit, under 500 ~ 550 ℃ cracking coking and generate black solid coke. Its appearance is black or dark gray honeycomb structure, coke block in the pores are oval, and through each other. [1] it is generally considered to be amorphous carbon body; Or a highly aromatic macromolecular carbide containing fine graphite crystals of acicular or granular structure of the carbon body. The ratio of hydrogen to hydrogen is very high, 18 to 24. The relative density was 0.9 ~ 1.1, ash content was 0.1% ~ 1.2%, and volatile matter was 3% ~ 16%.

Application:

Petroleum coke can be used in graphite, smelting and chemical industries depending on its quality

Equipment selection:

In view of the characteristics of petroleum coke powder's adhesion, the structural design of crushing host and classifier was optimized to effectively solve the adhesion problem. According to the physical characteristics of petroleum coke, the zhongjin impact mill was used.

Application model:

What ZJ had - C

Working principle:

What ZJ had - C series classification type impact mill is using high speed rotating hammer on the solid of revolution, blade, such as rod to impact of crushed material, borrow material with intense impact of rotors, the speed of high-speed collision between material and the shear grinding or side wall of rotors and stator, the implementation for the purpose of ultrafine crushing material.

Application advantages:

> this equipment can be adjusted in any particle size range required by petroleum coke industry, such as: D100=150 mesh, D100= 180 mesh, D100= 220 mesh, etc.

Aiming at the adhesion of petroleum coke powder, the structure design of grinding machine and classifier was optimized to effectively solve the adhesion problem.

> has high yield, no large particles, and particle size concentration and no over-grinding phenomenon, the output is more than 30% higher than similar models, especially the control of large particles.

-> easy wear parts are wear-resistant treatment, the service life is 5-6 times higher than similar models, and greatly reduce the contamination of iron impurities.

> dust remover adopts off-line ash removal technology and waterproof peritoneal filter material design, which greatly increases the filtration area and reduces the adhesion of powder on the cloth bag.

-> feeding system adopts full automatic control, the whole machine adopts full closed negative pressure operation, without dust pollution.

Minus > is more than 4-5t/h

Equipment features:

1. Suitable for ultra-fine grinding of materials with mohs hardness less than 5.

2, the particle size range than ordinary mechanical grinding finer, built-in high efficiency turbine classifier, can make after grinding qualified fine powder in time to discharge, avoid over grinding, can produce particle size distribution concentrated products, product fineness in d97=10 ~ 74 m range any adjustable.

3. Low energy consumption, large output, higher energy efficiency than traditional vertical mill, and processing capacity up to 4-5t/h.

4, the crushing media do not contact each other, small wear, high purity.

5. It can shatter and depolymerize the aggregate materials.

6. Full negative pressure operation, low noise, no dust pollution on site.
