Working principle This machine is a high-efficiency sample grinding mill that can obtain uniform powder according to the design concept of high-speed impact generation and crushing. It is suitable for the crushing of various dry materials such as cereals, feed, medicinal materials, chemicals, plant leaves, grass and other types .   Feature The design feature is the use of high-speed rotation of the working impeller (10,000 revolutions per minute) and the high-speed air flow formed by it, which causes the processed material to impact, roll and strongly rub against the abrasive belt to form fine particles. The particle size of the processed product can be changed according to the needThis machine is equipped with 40 mesh and 80 mesh screens. Drive power: 550 watts, single phase, 220 volts Working impeller diameter: 127 mm Impeller speed: 10,000 rpm Transmission mode: nylon flat transmission belt Feeding speed: 1-2 grams per second Discharging method: air flow transmission, screening, automatic deposition in the sample bottle Weight: about 16kg Size: 330×220×380mm
