Working principle of carbon black ultrafine grinding mill

GRINDING Mill equipment manufacturer HCM produces 5μm~45μm silica vertical mills. HLMX carbon black ultra-fine grinding mill equipment has high powder production efficiency, stable performance and high cost performance. The white carbon black process has a powder coverage of 325 mesh to 5 microns. It has a wide range of applications and is sold to more manufacturers. Helped many silica powder manufacturers to increase carbon black powder production and increase the market value of mineral powder.

White carbon black is the general name for white powdery X-ray amorphous silicic acid and silicate products, mainly refers to precipitated silica, fumed silica, ultrafine silica gel and aerogel, also including powdered Synthetic aluminum silicate and calcium silicate, etc.
1. White carbon black is used in colored rubber products to replace carbon black for reinforcement to meet the needs of white or translucent products.
2. In agricultural chemicals, such as pesticides, high-efficiency spray fertilizers, etc., using silica as a carrier or diluent can maintain long-lasting effectiveness.
3. Transparent colored and opaque toothpastes using silica as filler and abrasive have good flexibility, dispersibility, soft paste, good abrasiveness, and will not abrade the toothpaste tube; it can keep the medicinal properties of the medicated toothpaste stable. .
4. Used in adhesives made of natural rubber or synthetic rubber to provide thixotropy and reinforcement.
5. Using silica as paper filler can improve the ink penetration resistance and mechanical strength of paper, increase whiteness and reduce unit weight. The washability has been increased from more than 1,000 times to more than 10,000 times, and the aging time of artificially accelerated climate aging and artificial radiation exposure has been increased from the original 250 hours (level 1 powdering, level 2 discoloration) to 600 hours (no powdering, The paint film has no discoloration (color difference value is 4.8). In addition, the bonding strength between the paint film and the wall is greatly improved, the hardness of the paint film is significantly increased, and the surface self-cleaning ability is also improved.
6. Rubber is an elastomer with excellent stretchability, but its comprehensive performance is not satisfactory. In the process of producing rubber products, carbon black is usually added to the rubber compound to improve strength, wear resistance and aging resistance. However, Due to the addition of carbon black, the products are all black and of low grade. The advent of fumed silica (fumed white carbon black) in my country has laid the material foundation for the production of a new generation of rubber products with novel colors and excellent performance.

Selection of silica production equipment: HCM HLMX carbon black ultra-fine grinder

The HLMX mill equipment series ultra-fine vertical mill is a large-scale high-fine mill developed by HCM based on the HLM vertical mill based on advanced domestic and foreign technologies and suitable for large-scale production of ultra-fine processing of non-metallic minerals. Vertical grinding mill.

HONGCHENG MACHINERY HLMX vertical mill adopts ultra-fine powder multi-head classifier system. The product fineness can be adjusted between 325 mesh-2500 mesh (5μm-45μm), and the high output can reach 40t/h. It can be widely used in the ultra-fine grinding and processing of non-metallic mineral products such as limestone, 200 mesh muscovite, marble, heavy calcium, kaolin, barite, bentonite, muscovite, etc. It is an efficient, high-yield, environmentally friendly and energy-saving ultra-fine powder processing equipment.

Ultra-fine powder multi-head mill equipment: HLMX carbon black ultra-fine powder mill model parameters are as follows:

[Grinding disc diameter]: 1000-2400mm
[Raw material moisture]: ≤5%
[Production capacity]: 3-40t/h
[Finished product fineness]: 0-45μm, with secondary classification, it can reach 5μm
[Product Features]: It integrates crushing, drying, grinding and conveying, breaks through the bottleneck of ultra-fine powder processing capacity, can replace imported equipment, has a scientific and reasonable design, and a unique and innovative structure. It is an equipment for large-scale production of ultra-fine powder.
[Focus on areas]: Focus on large-scale grinding and grinding of non-metallic minerals with Mohs hardness below 7 and humidity within 6%, such as silica, coal, cement, slag, gypsum, barite, fluorite, marble, etc. Processing, the products have a number of national patented technologies, and their performance has reached the national leading level.

Industrial production process of silica micropowder
The first stage: broken
Large pieces of silica are transported to the raw material warehouse by special vehicles, and then the materials are sent to the jaw crusher by forklift/manpower for crushing until they are smaller than the feed size of the grinding mill.
The second stage: feeding
The silica crushed by the crusher is lifted to the storage hopper by the elevator. The storage hopper is discharged and then the feeder evenly feeds the host machine.
The third stage: grinding
During the grinding process, qualified products are screened by the screening system and then enter the collector through the pipeline. After collection, they are discharged through the discharge valve to become the finished product. Unqualified products fall into the main machine and are re-ground.
The fourth stage: collection of finished products
The purified airflow flows into the blower through the residual air duct above the dust collector. The air path is circular. Except for the positive pressure from the blower to the grinding chamber, the airflow in the other pipelines flows under negative pressure. The indoor sanitary conditions are good.

The grinding mill manufacturer HCM produces 80~2500 mesh HLMX silica ultra-fine grinding mills. The grinding mill equipment takes environmental protection as the first production benchmark, energy saving as the starting point, and the purpose of stabilizing and creating prices for customers.
