How to choose the hammer material of customized Double shaft hammer mill
It can be said that many farmers can afford customized Double shaft hammer mill. In many cases, the hammer head in the Double shaft hammer mill production line will wear out more quickly, and will face the situation of replacing parts or repairing the crusher.
It can be said that many farmers can afford customized Double shaft hammer mill. In many cases, the hammer head in the Double shaft hammer mill production line will wear out more quickly, and will face the situation of replacing parts or repairing the crusher. Take the hammer crusher as an example. The hammer head of the hammer crusher is a relatively simple and worn part. For normal production, the hammer head needs to be replaced or repaired. Then there are many kinds of hammer heads of hammer crusher, and the raw materials are also different. How to choose customized Double shaft hammer mill?
For the general customized Double shaft hammer mill, the harder the hammer, the greater the wear resistance. To improve the wear resistance of the hammer head, it is necessary to increase its hardness. As the hardness increases, the impact resistance will decrease. How to coordinate the suitable hardness and outstanding impact resistance of the hammer is the key to improving the wear resistance of the hammer. The main feature of the high manganese steel selected for the hammer crusher is: under the action of greater impact or contact stress, the outer surface layer will quickly undergo work hardening, and its work hardening index is 5 to 7 times higher than that of others, and martensite and The e-phase is prone to lattice distortion along the sliding surface to form a wear-resistant outer surface layer, while the inner layer still adheres to the austenite arrangement with excellent impact resistance. If the customized Double shaft hammer mill does not have enough impact force or the contact stress is small during use, it cannot make the surface work hardened quickly, and the wear resistance of high manganese steel will not be fully exerted. As mentioned above, in production practice, not all working conditions can make the high manganese steel hammer hair hardened or undergo a transformation from austenite to martensite. As a result, the hammer did not fully utilize the wear resistance potential of high manganese steel, and its service life was reduced.
The customized Double shaft hammer mill has compact structure, reasonable layout, convenient installation, good maintainability and easy operation. Especially the adaptability to cement production process layout is excellent. Save process layout space; it has special structural characteristics, namely the ‘big broken ratio’ for material crushing. The customized Double shaft hammer mill is divided into two types: ordinary hammer crusher and ring hammer crusher. Ring hammer type is generally used in the crushing of coal, coke and other industries.
