The shredding chamber is in a static state, and the shredding chamber relatively rotates by utilizing two shredding toothed rollers to form a V-shaped shredding toothed cavity, so that materials are crushed by the generated shearing force. After the material enters the gap between the two toothed rollers, the entered material is torn by the shearing force of the relative rotation of the two toothed rollers, and the material is sheared to 10-20mm. The ball milling chamber rotates at about 10000 horsepower, and the rated rotation speed is between 13 and 15 rpm;
The ball milling chamber is characterized in that the ball milling chamber is formed by the double functions of centrifugal force and friction force, so that the steel balls are attached to the lining plate of the cylinder body to rotate along with the lining plate, and when the steel balls are brought to a certain height, the steel balls are thrown down due to the gravity of the steel balls, and the fallen steel balls break up ores in the cylinder like a projectile. Meanwhile, in the rotating process of the ball mill, the mutual sliding among the steel balls also produces a grinding effect on the raw materials, and the materials are ground to the required granularity.
After the baked bricks are shredded, the materials with fineness of 325 meshes go up to enter an external silo through a cloth bag dust remover 6, the materials with fineness of 325 meshes go down to enter a vibrating screen 7 through a lifter, the screened oversize materials enter a shredding chamber through a conveying pipeline to be treated again, the undersize materials enter a classifier 8 and are screened by a separator, the materials with fineness of 150 meshes directly enter the next leaching process, the materials with fineness of 150 meshes which do not reach are conveyed to a feed inlet of a ball milling chamber to be ball milled again, and the steel ball consumption in ball milling is about 25% -35%. The grinding process can lead 80% of the grinding fineness of the product to reach 150 meshes.
