Cutter picks for Mining---Provide efficient and powerful cutting tools for mining operations such as coal mining.
Cutter pick is a tool used by mining machinery to cut coal and rock. It is composed of a shank, a carbide tip, the length of the pick, and the length of the tip, which are mainly fixed together through welding or inlaying processes. Mining picks are primarily used in the coal mining industry and are tools for shearers and roadheaders. They are installed on mining equipment to excavate and break coal or rock blocks.
The types of cutter pick
Mining picks are cutting tools for mining machinery such as roadheaders and shearers to cut coal seams. Mining picks can be divided into two types: conical picks and blade picks.
Conical Picks: They are cone - shaped, including a tip, a shoulder, and a shank. They are mainly used for cutting loose coal seams, aiming for high - efficiency coal falling and reducing the breakage rate of lump coal.
Blade Picks: They are flat, similar to a blade. They are suitable for rocks, semi - rock layers, and complex strata containing gangue, and need to withstand high impact forces and have strong wear resistance.
According to the application scenarios, picks can also be divided into shearer picks and roadheader picks. Shearer picks are suitable for softer strata, mainly for cutting loose coal seams; roadheader picks are mainly used for more complex rock strata.
Shearer Picks: They have a sharp - tapered head, emphasizing lightweight design and cutting efficiency, which facilitates quick penetration into the coal seam and reduces energy consumption.
Roadheader Picks: They have a thick body and a head with reinforced edges. They have high structural strength, can disperse impact forces, and prevent cracking.
Shearer Picks: Although coal is relatively soft, long - term friction still causes wear. Picks made of high - hardness materials and with ultra - wear - resistant coating technology can extend their service life.
Roadheader Picks: Since they face hard rocks, the wear rate is faster. Picks using special reinforcement processes and ultra - wear - resistant coating technology can significantly reduce the wear rate and maintenance costs.
Maintenance Instructions
- Install the picks correctly to ensure full integration with the shearer. If the picks are not fully attached to the shearer, during working time,it will not only accelerate the wear of the picks but also reduce the working efficiency of the shearer. Therefore, appropriate picks should be selected according to the size of the shearer.
- Reduce the pressure on the shearer picks. During the operation of the shearer picks, they are bound to bear pressure.For example,the shearer should be operated correctly, and the coal - cutting volume of the shearer should be reasonably controlled.
- Reduce the impact load capacity.When the picks are in use,each coal - cutting operation will generate a certain impact load. Therefore,the shearer should be operated rationally during use to minimize the impact load on the picks.
- Clean the shearer picks regularly.Since the picks often come into contact with substances such as coal,the degree of wear is very high. Over time,the connection between the picks and the shearer will become loose.Therefore, the coal lumps around the shearer picks should be removed regularly, and then a layer of lubricating oil should be applied to nourish them, which can extend the service life of the picks to a certain extent.
