Carbon graphite is a type of carburizing agent. It is widely used by steel plants because of its low cost. A large amount of carbon graphite powder will be produced during the mining process. Because the powder is finely divided, it is difficult to add it during the smelting process. , so a lot of graphite fine powder has been hoarded, exposed to wind, sun and rain, causing great environmental pollution. To solve the resource loss and environmental pollution during the storage and use of carbon graphite, carbon graphite pressure is indispensable. Ball machine assistance.
The working principle of the carbon graphite briquetting machine: the carbon graphite raw materials are transported to the mixer through a quantitative feeder and a belt, and the binder and curing agent water are added in proportion and then mixed and stirred, and the above-mentioned mixed materials are transported through the conveyor to the carbon graphite briquetting machine, and then transport the pellets through the conveyor to the dryer or finished product site for natural drying.
Improving the forming rate of the carbon graphite briquetting machine is of particular concern to customers. Here, Shisheng Machinery will briefly summarize for you several key factors that affect the forming efficiency of the carbon graphite briquetting machine:
(1) Carbon graphite particle size: The particle size and particle size distribution of carbon graphite have a certain impact on the pellet strength. Suitable particles can fully contact and bond with the binder. Granulation molding requires that the particle size of carbon graphite be controlled within -200 mesh particle size is preferably controlled at 85%-95%; however, the roll forming process has relatively low particle size requirements. Generally, the particle size is controlled at 70-80% at 3mm.
(2) Stirring of the mixture: The carbon graphite and the binder are uniformly mixed. After the carbon graphite and the binder are stirred and kneaded, the material surface is uniform and smooth, which increases the plasticity and significantly improves the strength.
(3) Molding external force: In addition to the performance of the binder, the strength of the pellet mainly depends on the molding external force. Appropriately increasing the molding external force can help increase the strength of the pellets.
(4) Amount of pellet binder: Choosing an appropriate amount of binder will not only make the pellets have higher quality, but also reduce the processing cost of the pellets. On the premise of ensuring the quality of the pellets, minimizing the amount of binder can reduce the impurities and production costs of the pellets. The dosage of GY type liquid pellet binder is generally 4%-8%, and the dosage of GY type dry powder pellet binder is generally 2-3%.
(5) Moisture content in pellet molding: The amount of moisture in carbon graphite molding is directly related to the quality of the pellets such as the molding rate, curing time, initial strength, and later strength. Practice has proved that the molding moisture of the two processes should be controlled between 8-15%.
Carbon graphite is added as a carburizing agent in the steel smelting process, which can effectively change the carbon content of steel and change the properties of steel. Adding carbon graphite pellets to the smelting process is more effective. Tenda carbon graphite briquetting machine is stable in operation, high in efficiency and easy to use. Shisheng Machinery can provide more reasonable carbon graphite molding solutions according to user production needs.
