Description

Technical Field

[0001] The present application relates to the technical field of activated carbon production, and in particular to a grinding mill for activated carbon production. Background Art

[0002] Activated carbon is a porous carbonaceous material with a well-developed pore structure and a large specific surface area, which gives it a strong adsorption capacity. Therefore, activated carbon is widely used in many fields, such as environmental protection, medicine, food processing, and chemical industry. In order to meet the different requirements of activated carbon powder in different fields, such as particle size, purity, and adsorption performance, the activated carbon needs to be finely processed. The activated carbon grinder is the key equipment to achieve this process. Through the grinding action of the grinder, the activated carbon raw material can be ground into a fine powder that meets the requirements, thereby increasing the surface area and adsorption performance of the activated carbon. Currently, activated carbon grinders grind the powder by rotating and squeezing the grinding discs. Large particles are easily produced during the toner production process, making fine grinding impossible. As a result, the toner does not meet the requirements. In addition, when discharging the material after grinding, there are few air vents and the discharge is not timely. As a result, the ground powder accumulates in the box, affecting the toner efficiency. Utility Model Content

The hot air enters the air flow pipe along the other of the three-way valve and is blown out by the air outlet of the air flow pipe. The air flow pipe not only makes the hot air blow the ground material in the box in multiple directions, but also the air outlet on the air flow pipe increases the displacement of the hot air, and then blows and discharges the powder in the box in time to avoid the accumulation of the ground powder in the box and affect the grinding, thereby improving the powder efficiency of the equipment. A feed pipe is provided on the top of the box, and a hopper is connected to the top of the feed pipe.

The controller controls the motor one, motor two, and motor three to start at the same time. The rotation of motor three drives the connected rotating shaft three to rotate, and the bearing seat does not move, thereby causing the powder classifier connected to the rotating shaft three to rotate.

[0013] In summary, the beneficial effects produced by this application are as follows:

[0014] 1. The grinding mill is equipped with a grinding disc and two grinding rollers. The rotation of the grinding disc makes the material on the grinding disc move evenly from the center to the edge under the action of centrifugal force, forming a layer of material. The grinding roller rotates and crushes the material. The relative movement between the grinding roller and the grinding disc and the grinding pressure grind the material into powder. The hot air generated by the hot air blower blows the powdered material, and then the powder is classified and selected by the powder classifier. The coarser particles are knocked down by the blades of the powder classifier and returned to the grinding disc for grinding, thereby ensuring the coarseness and fineness requirements of the activated carbon toner.
