The high manganese steel plate hammer has shorter service lifetime.Impact crusher machine has large crushing ratio, high working efficient, simple structure and it can have the selective crushing. It has seriously affected the impact crusher machine’s application. Compared with other kinds of crusher machine, it is fast be used and developed. The impact crusher machine’s plate hammer is fixed on the rotor through many methods, such as screw, insert method and wedge fixed and so on. At present, various kinds of impact crusher machines are widely used in coarse crushing, medium crushing and fine crushing stages.

The production capacity of the crusher is very important for the users of the crusher, and what are the factors that affect the link?.

Autogenous mills use ore exclusively as their grinding media but if hardness and abrasiveness of the ore does not lend itself well to full AG milling then a small charge of steel balls (6 to 15%) is added to assist in size reduction. The inside liner of AG/SAG mills consists of steel or rubber liners and are fitted with lifter bars. Ore particles in the body of the charge slide when moving to different heights and are subjected to attrition and abrasion forces. This is known as a Semi-Autogenous (SAG) mill.Autogenous (AG) and Semi-Autogenous (SAG) grinding mills have seen increased application in large mineral processing operations in recent years. Semi autogenous grinding mill, short for SAG mill, is a common type of grinding mills. AG/SAG mills bring about size reduction by a combination of impact, attrition and abrasion forces.5 to 1) these mills use large lumps of ore as the grinding media. Consisting of a large diameter cylinder relative to their length (typically 2 or 2. They are rotating/tumbling mills in which comminution (size reduction) takes place without grinding aids. Ore is swept up one side of the mill and at a certain point it falls back to impact the toe of the charge (bottom of mill).

As it will be seen, there areobtained important advantages in dressing the material as indi- One object of my invention is to dispense tracted from this mixture in the usual way teriahamong which the metal or metals, and another product consisting of coarse rock.same without any addition of water. This will be of great importance to mines situated in the high mountains, where water is not accessible. A further advantage is, that when this dry process is used, the buildings inclosing the machinery may be built in the cheapest way, as there is no need of keeping the cold away, where there is used no water.
