Raw materials grind by metallic board like
the form of two mandibles.
The mandible opens and closes.
Raw materials fall when the mandibles open.
Raw materials crush when the mandibles close.
And they crush to the size of the fist from the head.
Mainly, jaw crusher uses for the pre- processing of impact crusher.
2-2.Breaking (Impact Crusher)
The dram with the blade of the crusher turns.
The blade flicks away raw materials and makes raw materials impact with the metallic crash-board or raw materials continuously.
A bone material is made in this way. The basic grain size of the bone material is 4 - 1 mm, 1 - 0 mm by screening. But there are screens with various sizes. Products are carried with the paper bag or the flexible container bag.
2-3.Fine Grinding (Roller Mill , Ball Mill)
Mills are roller mill and ball mill.
Roller mill grinds raw materials with the metal roll. Grinned powders are classified into the particle sizes under 100 meshes, 325 meshes, and so on, by the cyclone. The product saves up at the hopper.
We put raw materials and alumina balls in ball mill with the inside alumina wall.
Raw materials grind by ball mill turning. Products are carried with the paper bag or the flexible container bag.
