basic information
【Features】 - By using four types of grinding rotors (chip hammer, swing hammer, saw blade rotor, high-speed rotor), it is possible to grind various materials. - By adjusting the rotational speed (maximum peripheral speed of 100 m/s) and the screen hole diameter, it is possible to achieve coarse to fine grinding. - It can handle large volumes with models up to 1000 type. - A combination of grinding rotors, bearings, shaft seals, screens, and grates can meet a wide range of needs. - The sealing structure of the casing and the selection of shaft seals allow for internal purging. - Replacement of consumable parts is easy. 【Rotor Types】 - Swing Hammer: The swing hammers on the outer circumference provide impact force to the raw material for coarse grinding. - Chip Hammer: The chip hammers on the outer circumference provide axe-like impact and shear force for grinding. - Saw Blade (Priodon): The saw blades on the outer circumference cut and grind the raw material.
