In the daily operation of mines, in addition to basic consumption of water and electricity, most of them are equipment wear and depreciation, and the proportion of wear and repair materials in the entire mine operation is still relatively large. This chapter will comprehensively sort out the brands of wear and repair materials.

For the main equipment in mining and washing, some vulnerable parts of the equipment are produced by the main equipment factory, which has poor substitutability. Some are produced by outsourcing factories or outsourcing factories, which have strong substitutability. For vulnerable parts or spare parts produced by the main equipment factory itself, as long as the main equipment factory does not close down, it is easy to achieve daily procedural procurement. However, currently, most users still do not have a good implementation of the optimized procurement process here. For replaceable vulnerable parts and repair materials, reliable brand suppliers are required to provide high-quality products and services, in order to minimize operating costs while ensuring the reliability of daily equipment operation.

In mining equipment, most of the wear and tear parts are the parts that come into direct contact with minerals during use. For the electric shovel, coal mining machine, tunneling machine, rock drilling jumbo, etc. mentioned in the previous chapter, the equipment brands are relatively concentrated, and most of them are produced by brand manufacturers or professional engineering. This chapter will not introduce them anymore. If there are alternative needs, they can be directly contacted with the board root interconnection platform. This chapter mainly introduces the brands of wear and repair materials for general products.

Belt Conveyor

Belt conveyors are universal equipment that the mining industry is familiar with. Tape, rollers, rollers, cleaners, conveyor belt joint materials, etc. are common replacement components. For tape and rollers, there are many production factories, whether domestic or foreign. If not specially customized, they are mostly localized production and procurement. In the daily operation of belt conveyors, or before procurement, the main brands that need to be considered include drum packaging, cleaners, deviation correction idlers, buffer beds, conveyor belt repairs, etc. Prior to 2015, the only major brand was TIP TOP from Germany. After 2015, with the improvement of the company's independent research and development capabilities, Chinese enterprises are also constantly growing. Currently, two brands are doing relatively more, one is MTH, the other is HUAO, which currently operates more in China and forms a tripartite alliance with Tiptop, but has not yet expanded into foreign markets.

Crushing And Grinding Equipment

For crushers, there are many types, such as toothed roller crushers, hammer crushers, cone crushers, rotary crushers, and jaw crushers. For jaw crushers, cone crushers, and rotary crushers, the material mainly comes into contact with the lining plate of the equipment. The wear resistance of the lining plate is very important, and the supply channel is relatively simple; For hammer crushers, the production and supply of hammer heads are relatively simple, and there are many manufacturers.

For toothed roller crushers, different brands and models of crushers use different toothed plates to crush different materials. Although the overall performance of equipment from MMD and ThyssenKrupp is relatively good, the supply of vulnerable parts toothed plates is outsourced. In recent years, on-site users have generally reported poor wear resistance and short service life of toothed plates, which seriously affects the normal production of the equipment. After 2018, TOP CRUSHER's growth can be described as very rapid. After decades of technological accumulation and the development and application of new materials, it has achieved world-class wear resistance and other aspects of the tooth plate. The tooth plates of different brands of crushers can be replaced after surveying and mapping, and the actual use effect on site is good.

For mills, the main wear components of semi-automatic mills and ball mills are lining and steel balls, which will not be discussed due to the large number of factories involved. For roller mills, the surface treatment technology of seemingly bulky rollers is still relatively advanced, and currently the only enterprise that has formed a brand is Chengdu Lijun.

Screening Equipment

There are many types of screening equipment, and regardless of the type of screening machine, there is no doubt that the sieve plate is a common consumable, made of materials such as polyurethane and stainless steel. The sieve opening and rate also vary depending on the minerals and sorting process. Although the single product value of the sieve plate is not high and looks relatively ordinary, it is relatively difficult to make simple things professional and become a brand.

For arc-shaped screens with relatively low usage in mines, the main brands of arc-shaped screens are Anhui YiXiang and Tangshan SenPu, which have done well in terms of professionalism and scale.

For conventional vibrating screens, both stainless steel and polyurethane screen plates are available. Foreign brands mainly include MULTITEC, while domestic brands mainly include Anhui FangYuan and Anhui YiXiang.

For laminated screens, due to their small mesh size, their R&D and manufacturing capabilities in specialized fields are very high for production enterprises. Foreign brands are mainly DERRICK, while domestic brands are mainly Anhui FangYuan. Anhui FangYuan also mentioned in previous chapters that companies attach great importance to technological research and development, and can compete with MULTOTEC in terms of professionalism and diversity of screen plates, with some products even surpassing MULTOTEC.

There are many other subcategories of mining equipment consumables, which will also be mentioned in the equipment introduction process in the following chapters. We hope to provide reference for mining users.

BUTTRESS ROOTS will provide the latest brand collection and supply to global mining users.
