PCFK series reversible impact hammer crusher (hereinafter referred to as crusher ) sets hammer crusher and impact crusher advantage in together, suitable for crushing compressive strength is not more than 120Mpa of medium hardness brittle materials, such as coking coal, anthracite, etc, fluidized bed boiler of the coal-fired power plant used coal, coal gangue, gypsum, alum etc material.
Working principle:
After material is to enter crusher through hopper, meet high-speed rotary hammer was hit onto the adjustable wear-resisting tooth board of the crusher inlet , first broken, the particles after broken basically the same uniform materials into the main crushing cavity and second main broken, in the crushing cavity have been homogenization materials particles from hammer head again gains kinetic energy, high-speed rushed to counterattack cavity internal gear-shape liner after tooth liner run up, again by hammer head broken, meanwhile material also influenced by each other's hitting and broken, so repeatedly circulation, in the impact cavity broken many times, finally the broken materials eduction from discharging port , the material which is finely finished product. Product granularity control through the rotor and counterattack plate gap adjustment to realize.
