Mining machinery crusher—Made-in-china Crusher

Ring hammer crusher is used for crushing brittle, medium hard, in whose surface water does not exceed 10% -15%、compressive strength not more than 100mpa of various materials for fine crushing, it is widely used in mining, cement, coal, metallurgy, , highway, fuel and other departments. To change the particle size, the screen meshes can be adjusted according different users’ requirements to meet their needs.

Hammer crusher is a type of crushing machine, which is made up of frame, rotors, grate bar, impact plate, and adjustment device. Our hammer crusher can be used to crush various semi hard and fragile materials, such as limestone, coal, salt, gypsum, alum, bricks, tiles, and coal gangue, and so on. The compression strength of the materials should be not more than 150 MPa.

The hardness and compression strength of stone have a great influence on crusher selection. Generally speaking, PE/PEX series manufactured by Henan Hongji can be used to crush materials whose compression strength is not more than 320Mpa.

1, in order to ensure the maximum yield of hammer crusher, charging must continuously even distribution of the rolls.2, should be regularly check whether the material mouth had blocked phenomenon, and in the motor stopped working to stop before feeding, when material completely dropped, the roll of a power outage, motivation may idling.

Jaw Crusher common symptom1:a suddenly stop of the host (commonly known as: boring car).Reasons:1)the block of discharge port lead the sealing; 2)the loose of rotation of the belt driving sheave rotating make the belt slip; 3)eccentric shaft bush sleeve is loose, causing the rack bearing no gaps in both sides, so that the eccentric shaft stuck, unable to turn; 4)workplace voltage is too low, which causes the host encounter aniseed,and the inability broken; 5) bearing damage.

Beijing time on March 11,Japanese waters around maizuru, Richter 9.0 magnitude earthquake.By this earthquake is influencing the NOK , Its biggest sealers bar mill production factory is located in f island, is the worst-hit areas of the earthquake.

The present age is already the information times,including informatization has four characteristics , namely intelligent , electronic , globalization and the mass . Many industry has entered informatization now , of course , mining machinery industry should also follow the era development steps and gradually towards intelligent direction,only do that can international standards.
