Pepper grinder is mainly applied to the low hardness materials crushed chili, food, chemicals, pharmaceuticals, dyes, paints, pesticides, metallurgy, ceramics, feed, non-metallic mining and scientific research and other enterprises, as the ultra-fine powder until powder processing best, most effective and most economical equipment. The machine is supported by bearing housing end of the spindle, the motor through the belt transmission, drive shaft and secured to the turbine shaft speed rotation. The turbine and the wear on the screen ring block, composed of rational, deputy compact, so that the material in the rotating air flow close to the impact of friction and strong ground, and leaves gaps between blocks and grinding in a re-grinding, the regulation of energy through the screen crushing between 40 mesh -325 mesh. The device is compact and reasonable structure, small size, low power consumption, high efficiency, smooth rotation, low noise, reliable seal, no dust pollution, self-cooling function was good, easy to install, easy to dismantle easy to repair, change or loss of pieces of convenience. Noisy turbo mill for the characteristics of a muffler device has been developed, which greatly reduces the work noise.
