Technical analysis of alloy hammer head of hammer Crusher for crushing coal mine materials:

When crushing related materials in coal mines, the hammer crusher is a model they often use, especially the double-rotor hammer crusher is a good effect and is favored by customers. Among them, the common wear-resistant accessories of the hammer crusher are the hammer head, the wear-resistant ring on the rotor hammer disc, the jacket, the hammer shaft, the guard plate, the grate plate, the screen plate and other wear-resistant material casting parts. Because of the requirements of its harsh working environment, these parts without exception need strong wear resistance, and Shandong Sanxiang Heavy Industry Co., LTD., as a crusher and its hammer parts manufacturer, according to the different requirements of the working environment of each part, the focus of research and development is slightly different. Here we mainly analyze the selection basis and process requirements of the high chromium alloy hammer produced by our company for the material crushing in the coal industry.

Before the coal mine with the hammer crusher hammer head multi-forging or high manganese steel material, which is characterized by good stability, but the overall wear resistance is general, especially for the crushing of coal gangue containing iron, nickel and other impurities, the effect is very general. In the crushing process of coal and other materials, due to the low hardness of coal, it is not enough to produce enough work hardening of high manganese steel, so that the wear resistance of high manganese steel can not be fully played, and the service life is short, which increases the maintenance costs and labor costs of the crusher, and reduces the work efficiency. Therefore, the high chromium alloy hammer came into being, and the hammer made of high chromium alloy steel replaced the original forging or high manganese steel, achieving a qualitative breakthrough in the wear resistance of the crusher hammer.

The main wear-resistant material of the high chromium alloy hammer is high chromium wear-resistant alloy steel, cast by bimetal composite technology, and the hammer handle part is made of high manganese steel to ensure the toughness of the whole hammer handle part. In addition, the hammer part is made of high chromium alloy rigid material, mainly to increase the wear resistance of the hammer and extend the service life of the entire hammer.

The high chromium alloy hammer produced by Shandong Sanxiang Heavy Industry Machinery has the following casting performance characteristics:

First, because it has good fluidity in the casting process, it can achieve customized service according to customer requirements.

Two: with a large concentration, convenient customization molding, greater flexibility.

Three: with a tendency to crack, in the production of high chromium alloy castings must ensure that all parts are heated evenly, otherwise it will be easy to crack.

Because the heat treatment process can make high chromium wear-resistant cast iron parts obtain excellent wear resistance, the castings will undergo annealing and quenching treatment during the casting process. The purpose of annealing is to eliminate the internal stress generated during the casting process, increase the shape and toughness of the casting matrix, make the composition or organization of the material uniform, and prepare for the subsequent heat treatment process. The purpose of quenching is to obtain martensitic structure of high chromium wear-resistant cast iron, which is an important process to ensure high wear resistance of high chromium alloy hammer. After quenching the hammer head in order to eliminate stress, improve toughness, to avoid causing cracks in use, the need for low temperature tempering.

High chromium alloy hammer head and forging or high manganese steel hammer head through the actual production test, its service life is about 2.5-3 times that of the latter, which greatly improves the use efficiency of the hammer crusher in the field of coal crushing, in general, the cost performance is higher.

Anhui province has always been an important area for the sales of our company's crusher products, because Anhui crusher manufacturers are less, the national crusher manufacturers are mainly concentrated in Henan Province and Shandong Province Linyi City, which is the current domestic crusher manufacturers in general distribution. Think of our hammer crusher high chromium alloy hammer accessories products in Anhui Province, the annual consumption of the entire accessories product sales accounted for a high proportion.

Anhui rock crusher machine manufacturers less, our company produces crusher products in the whole Anhui province has many customers, such as hammer crusher, impact crusher, cone crusher products are widely recognized and loved by them. And the whole Anhui Province high-quality limestone, very suitable for our rock crusher mill products in the development of the market there, is a must for many crusher manufacturers.

In summary: Shandong Sanxiang Heavy Industry Co., Ltd. production of hammer crusher special high chromium alloy hammer head because of its good wear resistance and low failure rate, in the crushing of coal mine materials compared to forging or high manganese steel hammer much stronger, its cost performance is relatively high. As a crusher hammer manufacturer, our customers can choose to cooperate with Shandong Sanxiang stone crusher machine factory according to the actual situation of their own production, and we can implement customized services to samples.
