During the production of chilli grinding machine, the motor drives the main shaft and the turbine rotating at high speed. Grinding blocks turbine ring and mesh on the composition of crushing and grinding which is of compact structure. When the chilli peppers going from the hopper into the machine cavity, make the chilli pepper crushed by the close friction and strong impact to the inner edge of the turbine blade under the rotating air flow, and ground again between the gap of the blade and the grinding block. In this crushing and grinding chilli pepper at the same time, a lot of air sucked into the turbo, these gases play a role of a cooling machine, grinding chilli pepper and transferring chili pieces. The final crushed fineness of chilli pepper depends on the mesh size and the amount of pepper pieces and circulating air going through.
