►Raw Mill Introduction:
Raw mill adopts big cover,that means end cover and quill shaft as whole casting.In the big end cover and discharge system,adopting unique streamline design reduces ventilation resistance,increases the effective volume,easy to discharge and improve the mill capacity.Raw mill adopts multi-warehouse structure and combination design in mill lining plate;also desigh different liner plate according to different raw mill stages,which improve the grinding efficiency greatly.Raw mill voltage is negtive,preventing the powder leakage phenomenon.
►Application:
Raw mill is mainly used in grinding raw materials and final products in cement plant. It is also suitable for grinding various ores and other materials in the metallurgy, mine, chemical, construction and other industries. Besides, it has two forms of milling, one is an open form, and the other is a recycle close form equipped with powder concentrator. It is widely applied in many industries and has convenient operation.
►Performance Feature:
1.It has many advantages such as, strong adaptability, continuous production, large crushing ratio, easy to adjust the size of the products.
2.It is suitable for both dry production and wet production,also can allow the milling and drying processing simultaneously.
