The ACM/A series are highly efficient super-fine punch-action mechanical micro grinding machines of performing the complete process of material grinding, separation and making of the finished product within the same tightly integrated system. 1. Built-in separation mechanism-preventing over-grinding. 2. Able to produce uniform granules of required sizes by adjusting the speed of the stage-separation wheel(s) or by adjusting the strength of the blower(s). 3. Powerful blowing and strong self-cooling capability, suitable for grinding heat-sensitive materials. 4. Different grinding accessories/devices are used according to the hardness of the material being ground; different types of materials (alloyed carbon steel, stainless steel, ceramics etc) are available for the Machine's inner linings and product extracting system, meeting the needs of different industries. 5. Both manual and programmable auto-controlled machines available. The machine is suitable for super-fine grinding of various types of brittle materials. Material hardness (Mohs scale)
