Alloy Hammer At present, the common hammers used in the crusher are high manganese steel hammer and forging hammer, both of these two hammerheads are with the shortage of short using cycle, not wear-resisting, high cost and low efficiency. Our company developed a new type alloy hammer: Combined the high chrome multielement alloy and medium carbon low alloy wear-resistant steel �together, so the hammers are with high wear resistance and good toughness. Now our products have sold to hundreds of ore-dressing and sand plant all over the world. After long-team tracking service, Our company concluded: Our alloy Crusher hammers? using life is almost 2-3 times longer than that of high manganese steel hammers, 3-5 times longer than that of the forged hammers. Therefore create considerable economic benefits and social benefits for the users. . Product characteristics The hammer has many advantages: the handle has good toughness, not easily broken; Rockwell hardness can be HRC 65-67, good abrasion resistance, long life and other advantages. . The use of range The product is mainly applied to the mining enterprises and gr zavel plant hammer crusher use. . Specifications 1. the hammer thickness in two sizes: 55,65 2. model: L=200,220. A total of 14 kinds (Each hammer are marked) -

Ball mill liner Three characteristics: 1.High wear and impact resistance With scientific and reasonable formulation of alloy elements, the high manganese steel liner is multivariate micro-alloying on the basis of the original high-manganese steel, then it has good physical and chemical properties, such as the hardness hrc52-56, the impact toughness value larger than 150j, using life is more than twice as high manganese steel. So it can tolerate a huge impact strength. In a long-term work it can keep lining surface state so ensure a stable increase of more than 5% of production. 2. High strength, high toughness By using the special quenching medium agent with thermal stability in the quenching process, high manganese steel liners combine high strength, high hardness and high toughness perfectly, which can satisfy high wear resistance and high impact loads process requirements. 3.High cost-effective, strong adaptability Through the reasonable alloying elements and advanced process of our company, high manganese steel liner has a high quenching hardness, high toughness characteristics. So that it not only has good wear resistance, but also shows excellent price compared with the ordinary liner. It can adapt to mine wet grinding, dry grinding, mixing mill and etc. High manganese steel liners use advanced heat treatment process and change the height of ball mills peak, trough. These all help improve grinding rate of ball mill and increase the 20% of machine-hour capacity. Rong mao is ball mill liner, high manganese steel ball mill liner, magnetic liner, mill lining manufacturer in china -

High manganese steel ball mill liner High manganese steel ball mill liner is used to protect the direct impact and wear of grinding ball and materials. At the same time, the different shapes of high manganese steel liners are used to adjust the movement state of the mineral, thereby enhancing the efficiency of grinding and crushing, which is helpful to improve the grinding efficiency, increase the output and reduce the mental consumption. High manganese steel ball mill liner is used to protect the direct impact and wear of grinding ball and materials. At the same time, the different shapes of high manganese steel liners are used to adjust the movement state of the mineral, thereby enhancing the efficiency of grinding and crushing, which is helpful to improve the grinding efficiency, increase the output and reduce the mental consumption. Main applications: High manganese steel liner can be used for ball mill, crushers, loaders, excavators, cutting tools, bulldozers, digging bucket and knife plate, screw conveyor and other wear-resistant structural parts production equipment, by gas cutting processing and various welding, despite the steel sheet with high strength , but cold bending performance well, it can be cold forming.

Magnetic Liner For the conventional ball mill liner, ore pulp and grinding media wear and impact the liner directly while in operation, along with the electrochemical corrosion at the same time. or the conventional ball mill liner, ore pulp and grinding media wear and impact the liner directly while in operation, along with the electrochemical corrosion at the same time. But for the magnetic liner, the working principle is quite different: these magnetic liners are arranged alternately in the ball mill to form a strong magnetic field, the magnetic liner attracts a layer of broken or small steel balls and ferromagnetic minerals to the liner surface when in operation, thus forming a natural dynamic protective layer. In initial period, the workers can add broken balls or iron powder to help form the protective layer, which often can be 20~30mm. So the service life of the magnetic liner is extended greatly, is generally 10 times even dozens of times of high manganese steel liner. Material: Material and production process of the protective metal casing: Our company is researchers developed a special non-magnetic material, which consists of  military special alloy metal and some necessary elements. This type material has many great properties:such as wear-resistant, acid-proof, Alkali-resistant,corrosion resistance and excellent non-magnetic permeability. All these properties enable the formation of sufficient strength and thickness of protective layer . By using EPC casting process, we produce metal casing with neat appearance and precise size, so the contact surface of the cylinder and magnetic liner can up to more than 95%. Material of the magnetic Based on years of experience, our company always use the the magnetic material with stable performance and reliable quality,this ensures high quality of our products, and in some vulnerable parts we add some NdFeB magnetic materials. Material of the waterproof glue Our company use imported waterproof glue, the strong adhesive makes the magnets and the protective layer firmly bonded together. And the good water resistance propertity makes the waterproof layer on the magnet surface have sufficient strength, not destroyed in the transportation, installation and use. -

Crusher Hammer Matters Needing Attention 1. Feed process to keep the size of raw material can not be too big, with a diameter of less than 100 millimeter advisable. 2. When the machine runs, the operator can not be absent without leave, so can discover problems and stop in time. 3. Check and exchange the hammer regularly and timely. 4. Strictly avoid all kinds of metal objects into the hammer crusher. Rong Mao is a leading manufacturer of Wear Resistant Metal Alloy Steel Hammer, crusher hammer in China. -
