What equipment is used in the carbon black grinding production line?
Author : Clirik
Carbon black is an amorphous carbon. Light, loose and extremely fine black powder with very large specific surface area, ranging from 10-3000m2/g, which is obtained by incomplete combustion or thermal decomposition of organic matter (natural gas, heavy oil, fuel oil, etc.) under the condition of insufficient air product. Specific gravity 1.8-2.1.
Carbon Black
Those made of natural gas are called "gas black", those made of oil are called "lamp black", and those made of acetylene are called "acetylene black". In addition, there are "slot black" and "furnace black". According to the properties of carbon black, there are "reinforcing carbon black", "conductive carbon black", "wear-resistant carbon black" and so on.
Carbon black can be used as a black dye, used in the manufacture of Chinese ink, ink, paint, etc., and also used as a reinforcing agent for rubber.
How to choose a carbon black processing equipment?
Jaw crusher: The processing fineness is 10-105mm, and the maximum processing capacity is 90 tons/hour;
Hammer crusher: the processing fineness is below 25mm, and the maximum processing capacity is 45 tons/hour;
Box crusher: the maximum feeding size is 600-800mm, the finished product fineness is less than 50mm, and the processing capacity is 160 tons/hour;
European version coarse powder mill: the processing fineness is below 3mm, and the maximum processing capacity is 100 tons/hour;
YGM high pressure suspension roller Raymond mill: the processing fineness is between 15-200 mesh (fineness can be adjusted arbitrarily);
HGM three-ring medium-speed micro powder grinding mill: the processing fineness is between 200-3000 mesh (the fineness can be adjusted arbitrarily);
What is the scope of application of carbon black grinding mill?
Among the carbon black processing equipment, HGM series three-ring four-ring medium-speed micro-powder mill is a new star milling equipment successfully developed and manufactured by Shanghai CLIRIK Machinery Co.,Ltd.
HGM micro powder grinding mill can not only process carbon black, but also Ultrafine powder processing of non-flammable and explosive brittle materials with medium and low hardness, Mohs hardness ≤7, such as calcite, chalk, limestone, dolomite, carbon black, kaolin, bentonite, talc, petroleum coke, magnesite Ore, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alumite, graphite, fluorite, phosphate rock, potassium ore, pumice, etc. 100 Various materials.
Working principle of carbon black grinding mill
When working, the main motor of the grinding equipment drives the main shaft and the turntable to rotate through the reducer, and the roller pins on the edge of the turntable drive dozens of grinding rollers to roll in the grinding ring raceway.
The raw carbon black ore is crushed into small particles by the hammer crusher and then sent to the storage bin by the elevator, and then through the vibrating feeder and the inclined feeding pipe, the carbon black particles are evenly sent to the upper bulk plate of the turntable. superior.
The carbon black particles are scattered to the periphery of the circle under the action of centrifugal force, and fall into the raceway of the grinding ring.
They are impacted, rolled and ground by the ring roller. The outside air is sucked into the machine, and the pulverized carbon black powder is brought into the classifier.
The rotating impeller in the powder separator makes the coarse carbon black powder fall back for regrinding, and the fine powder that meets the requirements enters the cyclone powder collector with the airflow and is discharged from the discharge valve at the lower part of the powder, which is the final carbon black ultrafine powder.
The airflow with a small amount of fine dust is purified by the pulse dust collector and discharged through the fan and muffler.
Carbon black mill performance characteristics
1. Efficient
In the case of the same fineness of carbon black powder and the same motor power, the output of carbon black milling machine is more than double that of jet mill, ball mill, etc.;
2. The wearing parts have a long service life
Grinding rollers and grinding rings are forged with special materials, which greatly improves the durability. Under the condition of the same fineness of materials and finished products, the service life of the wearing parts of the carbon black micropulverizer is 2-3 times longer than that of the impact crusher and the turbo pulverizer, generally up to more than one year; this When processing calcium carbonate, carbon black and calcite, the service life of the grinding equipment can reach 2-5 years;
3. High safety and reliability
Because there are no rolling bearings and screws in the grinding chamber, there is no problem that the bearing and its seals are easily damaged, or the problem of damage to the machine due to loose screws;
4. High product fineness
The fineness of the finished carbon black powder processed by this grinding equipment can reach D97≤5μm at one time;
5. Less pollution to the environment
The use of environmentally friendly pulse dust collectors and mufflers in the grinding equipment greatly reduces dust and noise and does not pollute the surrounding environment.
