Coal pick is one of the vulnerable parts in coal mining and roadway excavation machinery, and it is the main tool for coal crushing. Durability and service life of other related components. Coal picks are divided into two types: knife-shaped picks and pick-shaped picks. The shank of the pick is cylindrical, and is fixed on the tooth seat with a spring ring, which is very convenient for disassembly and assembly. The structure is simple, it can be clicked to plan coal, the cutting depth is large,

Introduction of the reasons for the failure of coal picks and the factors affecting the price of the products Coal pick is an essential mining equipment accessory for coal mining, and it is the main tool for coal falling and coal crushing. Coal picks are divided into two categories: shearer picks and roadheader picks. The roadheader pick is a part of the mining roadheader; the shearer pick is used in conjunction with the shearer, and is suitable for coal mining. Because the picks often work u

Advantages of coal picks 1. There are many kinds of coal picks with different shapes, which can adapt to different working conditions. The working environment of the shearer is different. For example, some coal rocks are less hard, so engineers need to use coal picks of the same hardness. Otherwise, they need to use the same model of high hardness pick. Common shearer pick shapes are flat picks and picks. Among them, the flat pick is suitable for cutting coal with different hardness such as har

Causes of cold cracking of coal picks As a part of mining equipment, shearer picks are relatively easy to wear, and cold cracks will occur during the working process. The following are the reasons for cold cracking of coal picks:

A brief introduction of carbide coal mine rock drill bit Coal bit is now divided into two kinds, hard alloy bit and diamond composite bit. The two wing working parts of hard alloy coal bit use hard alloy as cutting teeth, mainly used for soft bottom layer, the alloy cost is low. It still holds an important position in the market. Diamond composite bits are used as cutting teeth on the two wings of the coal bit. The application of diamond composite bits greatly improves the drilling efficiency o
