The invention belongs to the technical field of grinding equipment and particularly relates to activated carbon grinding equipment. The activated carbon grinding equipment comprises a hoper, a first-stage grinding device, a screening module and a second-stage grinding device. The first-stage grinding device and the second-stage grinding device conduct driving synchronously. The first-stage grinding device comprises a grinding box, a grinding rotary shaft, a grinding spiral lamina and grinding rods. The grinding rotary shaft is connected to the interior of the grinding box. The grinding rotaryshaft is provided with grooves in the length direction. Magnets I are inlaid in the grooves. The grinding rotary shaft is sleeved with a plurality of grinding rings distributed uniformly. The grindingrings are provided with magnets II. The grinding spiral lamina is fixed to the grinding rings. The screening module is used for screening out activated carbon meeting the standards and guiding activated carbon not meeting the standards into the second-stage grinding device for continuous grinding. According to the activated carbon grinding equipment, differential rotation is formed between the grinding rotary shaft and the grinding spiral lamina, the grinding time of the activated carbon is prolonged, the activated carbon is ground more sufficiently, and the grinding quality is improved.
