What Machine Is Used For Coal Crushing? Coal Crushing Process

Coal crushing is a key step in achieving refined utilization of coal, and plays a vital role in improving combustion efficiency and reducing environmental pollution. This article will deeply analyze the coal crushing process, explore the types of applicable crushing equipment, and combine equipment price factors to provide professional and objective optimization suggestions for coal processing companies.

Overview of coal crushing process

Coal crushing refers to the process of crushing large pieces of coal into the required particle size by physical means to meet the requirements of coal powder particle size for different purposes (such as power generation, chemical industry, metallurgy, etc.). This process usually includes three stages: coarse crushing, medium crushing and fine crushing. Appropriate crushing equipment should be selected in each stage to ensure the crushing effect and efficiency.

Detailed explanation of coal crushing equipment

Jaw crusher: As a commonly used equipment in the coarse crushing stage of coal, the jaw crusher can effectively handle large pieces of coal and achieve preliminary crushing with its powerful crushing force and large feed port design. Its working principle is that the moving jaw plate periodically reciprocates, and forms an extrusion and splitting effect with the fixed jaw plate to break the coal.

Impact crusher/cone crusher: In the secondary crushing stage of coal, impact crusher or cone crusher is often used. Impact crusher breaks coal through the impact force generated by high-speed rotation of the rotor, which is suitable for medium-hard coal; cone crusher relies on the internal lamination crushing principle to perform efficient secondary crushing of hard coal and has good particle shape control ability.

Hammer crusher/vertical shaft impact crusher (sand making machine): In the fine crushing stage, hammer crusher or vertical shaft impact crusher (sand making machine) can further crush coal to the ideal particle size. Hammer crusher relies on high-speed rotating hammer head to hit and shear coal; vertical shaft impact crusher uses the principle of “stone hitting stone” or “stone hitting iron” to achieve fine crushing.

The manufacturing cost of coal crushing equipment of different types and specifications varies significantly, which directly affects the selling price. Users should choose suitable equipment according to actual production needs (such as processing capacity, output particle size, coal hardness, etc.) to avoid waste of resources due to excessive investment.
