Working Principle

The main motor drives the spindle and turntable to rotate through the reducer, and the roller pin at the edge of the turntable drives dozens of grinding rollers to roll in the grinding ring raceway. The bulk material is broken into small particles by the hammer crusher and sent to the storage bin by the elevator, and then through the vibration feeder and the inclined feed pipe, the material is evenly sent to the bulk tray on the upper part of the turntable. The material is scattered around the circle under the action of centrifugal force, and falls into the raceway of the grinding ring, which is impacted by the ring roller, rolled and ground, and becomes powder after the processing of three layers of ring paths. The high pressure fan inhales the external air into the machine through the suction effect, and brings the crushed material into the powder separator. The rotating impeller in the separator makes the coarse material fall back and re-grind, and the fine powder that meets the requirements enters the cyclone powder collector with the air flow and is discharged by the discharge valve at the lower part of the product, while the air flow with a small amount of fine dust is discharged through the fan and muffler after the pulse dust collector.

Characteristic and feature of Z series micro-powder grinder

(1)High efficiency and energy saving, in the fineness of the finished product and the motor power are the same, the output is more than twice that of the air mill, stirring mill and ball mill;

(2)The wearing parts have a long service life, and the grinding roller and grinding ring are made of special materials, which greatly improves the utilization degree. Generally up to more than one year, processing calcium carbonate, calcite, the service life of up to 2-5 years;

(3)High safety and reliability, because there is no rolling bearing and no screw in the grinding chamber, there is no problem of bearing and seal damage, and there is no problem of screw loosening and destroying the machine.

(4)Environmental protection, the pulse dust collector to capture dust, the use of muffler to reduce noise, with environmental protection.
