In coal mining, Coal Mining bits failures such as alloy fracture, handle breakage and wear are often encountered. The main reasons are insufficient bending strength of the alloy, poor wear resistance and fatigue resistance of the alloy, unprofessional tooth steel material and processing technology, etc.
Today, let us take a look at how to choose coal picks with longer service life, higher cutting efficiency, better hardness and wear resistance, and higher cost performance.
What factors should be considered when choosing coal Mining picks?
Coal mining working conditions
The hardness, thickness and coal rock conditions of coal seams in different places are different, which leads to different mining conditions. Therefore, when choosing picks, different pick models should be matched according to different conditions.
Mining bits quality factors
There are many pick cutter manufacturers on the market, but the quality is uneven. The most common problems with ordinary pick cutters are broken handles, wear resistance, alloy head falling off and other quality problems. This directly leads to workers frequently changing teeth, reducing work efficiency and may even cause personnel safety problems.
Coal mining machine model factors
If the picks of different models of coal mining machines are not matched properly, it will cause problems such as low work efficiency and machine damage. Therefore, strict control must be exercised in the selection of picks.
How to choose suitable coal mining pick?
Different coal mine working conditions are suitable for different picks
First of all, we should fully understand the working conditions of coal mines. If the coal seam is hard and the coal rock content is high, we should choose picks with relatively large alloy heads. For soft rocks, we can choose picks with smaller alloy heads and smaller models to improve coal mining efficiency. If the coal rock is well developed and has cracks, we can consider choosing picks with wear-resistant layers to increase service life and reduce the ineffective action of frequent tooth replacement.
Don’t just focus on the price, look at the cost performance
The quality of the pick directly determines the mining efficiency and safety, while the price affects the mining cost. Therefore, it is necessary to choose a pick with high cost performance. Good quality coal picks are generally very particular about material selection and production technology.
Look at the alloy head material
The most important factor for the pick to achieve the best effect is the quality of the alloy head. The technical strength of first-line brands is generally concentrated on the research and development of alloy heads and wear-resistant materials. Imported raw materials will be selected. At the same time, the alloy formula can be independently customized according to the characteristics of the rock formation, which can not only ensure the strength of the pick, but also take into account the hardness.
The founder of BAUSDE pick cutters has more than 20 years of production and research and development experience in the field of alloy materials. The alloy quality is superior, so you can pay attention to this point when purchasing.
Pay attention to this point when purchasing Mining bits?
Alloy head design process,
Ordinary manufacturers’ pick alloy heads are conical in design. Alloy heads with prism design have higher mining efficiency, but at the same time, they are more challenging to alloy quality. Manufacturers who dare to make prism design also have very good alloy quality.
Pick welding process,
Ask the manufacturer about the welding fullness of the alloy head. The higher the fullness of the pick, the firmer the alloy head will be and it will not fall off easily.
Tooth body processing technology,
On the one hand, it is necessary to understand whether the material of the tooth body is good steel, and also pay attention to the heat treatment process. At present, international brand products all use cold forging technology to ensure that the internal structure of the tooth body does not change and prevent the tooth handle from breaking to the greatest extent.
BAUSDE MINIING BITS is benchmarked against international leading enterprises. It is ingenious in raw material selection and process design, fully guarantees product quality, and is the “most cost-effective” pick in the industry.
