Description
Technical Field
[0001] The utility model relates to the technical field of grinding devices, in particular to a grinding device for rough processing of chemical raw materials. Background Technique
[0002] The grinding device is used to grind chemical raw materials such as phosphate rock. The grinding device consists of a mounting frame, a rotating shaft, a grinding cylinder, a feeding and discharging port, a lid, a motor, a pulley set, a belt and grinding balls. When rough processing and grinding phosphate rock, the phosphate rock is fed into the grinding cylinder through the feeding and discharging port, and then the lid is fixed into the feeding and discharging port. The motor on the mounting frame is started, so that the first pulley rotates. Through the belt, the rotating shaft on the second pulley rotates, and then drives the grinding cylinder to rotate, thereby driving the internal grinding balls to rotate.
