The invention discloses a high-efficient low-consumption safe powder coating pulverizer. The pulverizer comprises a machine body, a feeding inlet and the like and is characterized in that the pulverizer further comprises a centrifugal crushing mechanism, an electrostatic eliminator and radiating fins; the feeding inlet is formed in the machine body; discharging outlets are formed in the bottom of the machine body; a motor is mounted on one side of the machine body; the radiating fins are mounted on the two sides of the machine body; and the motor is connected with a rotary shaft and the centrifugal crushing mechanism. The pulverizer is provided with the centrifugal crushing mechanism, powder is rapidly crushed through centrifugal force, the crushed powder with small size flows out of through holes in the tangential direction, the production cycle is greatly shortened, and the production efficiency is improved; the radiating fins are arranged for replacing refrigerating pipes, the radiating area of the machine body is increased, powder coagulation caused by too high temperature in the machine body is avoided, guarantee is provided for smooth machining operation, and the production energy consumption is reduced; and the electrostatic eliminator is arranged, the situation that powder in the machine body floats and explodes when heated is avoided, the accident rate is lowered, and the equipment using safety is improved.
