组成的粉碎室座在机架上，粉碎转子由电动机通过传动带直接驱动，当物料在投料口进入后，在转子上受粉碎刀高速旋转产生的离心力的作用下，对物料进行剧烈的冲击，并受定刀的阻击后进行碰撞、摩擦、挤压而粉碎。粉碎后物料的细度由腔体下部的筛网来控制，过大的颗粒不能通过筛网，在腔体内继续旋转，再次被刀粉碎，直至到了一定的细度后过筛，在下料口排出。
This machine consists of airframe, rotor and support, grinding rotor is driven by the motor through transmission belt, after materials got into, under the action of centrifugal force which formed by high speed grinding knives, dramatic impact on materials, and be collision blocking, rubbing, squeezing and crushing by the fixed blades. The fineness subjected by the screen of the lower chamber, bigger powder than the apertures of the screen can’t pass, return chamber to regrind, discharged from the discharge port until the fineness can be up to the apertures of the screen.
性能特点(Performance characteristics)
1.本机的投料口大、进料范围可在5-50mm之间，宽大了使用范围。
2.转速高、破碎能力大、破碎粒度均匀、产品粒径容易控制。
3.粉碎室上部的左、右箱盖都能翻转，故粉碎刀和筛网清洗、更换容易。
4.箱体顶部装有安全开关联锁，在箱盖打开后无法启动转子，安全可靠。
5.设备设计合理，结构紧凑、运转平稳、性能可靠、适用范围广。
1.The feeding port are big, the size of feeding materials can be up to 5-50mm, so that the applications are wide.
2.High speed, large grinding capacity, uniform crushing particle, easy to control particle.
3. The left and right cover on the top of grinding chamber can be turn so that the grinding knives and screen are easy to exchange and clean.
4.Top box equipped with a safety interlock switch, the rotor can’t operate after opened the cover, so it is safety and reliable.
5.Equipment has reasonable design, compact structure, smooth operation, reliable performance, wide range of applications.
