Carbon black is an amorphous carbon. It is a light, loose, very fine black powder with a huge surface area of 10 to 3000 m²/g. It is the product of incomplete combustion or thermal decomposition of carbonaceous substances (coal, natural gas, heavy oil, fuel oil, etc.). in the absence of air. It can be used as a black dye to make Chinese ink, ink, paint, etc., and can also be used as a reinforcing agent for rubber.

Performance characteristics of carbon black ultra-fine vertical grinding machinery and equipment:

1. Stable and reliable performance, wear-resistant accessories, easy replacement and operation.

2. The fineness is adjustable. According to different applications, the fineness of the finished product can be adjusted by adjusting the powder separator.

3. The carbon black vertical mill adopts pulse dust removal equipment to reduce dust pollution and higher waste collection efficiency.

4. The arc-shaped inspection port ensures safe and reliable maintenance and does not affect the air volume.

5. High powder purity due to no grinding media wear.

Carbon black ultra-fine vertical mill mechanical equipment powder milling process

The first stage: 

crushed large pieces of carbon black are transported to the raw material warehouse by special vehicles, and then the materials are sent to the jaw crusher by forklifts/manually for crushing, and crushed to a size smaller than the feed size of the pulverizer.

The second stage: 

the carbon black after being crushed by the crusher is lifted by the elevator to the storage hopper, the storage hopper is discharged, and then the feeder is evenly fed to the host.

The third stage: 

the qualified products in the grinding process are screened by the screening system and then enter the collector through the pipeline. After collection, they are discharged through the discharge valve to be the finished product. The unqualified products fall into the main engine for re-grinding.

The fourth stage: 

the air after purification of the finished product flows into the blower through the residual air duct above the dust collector. The air path is circulating. Except for the positive pressure from the blower to the grinding chamber, the air flow in the rest of the pipeline flows under negative pressure, and the indoor sanitation better condition.

What are the advantages of a carbon black grinder?

1. Higher productivity: The material selection of grinding rollers is upgraded, and the components are firmer and more reliable. During the grinding process, the grinding pressure is increased by about 15%-20%, which speeds up the grinding speed and improves the productivity.

2. The discharge can be controlled: Adjust the operating parameters to control the discharge, run accurately, the powder separator can be controlled by frequency conversion and strictly control the fineness of the discharge.

3. Long service life: The bearing is more durable, the effective working cycle is longer, the maintenance is simple, and the service life of the whole machine is 3-5 times that of other mills.
