Understanding the Common Crushing Methods of Ore Crushers

To transform ore into sand, it undergoes processes including primary crushing, secondary crushing, tertiary crushing, and screening. Ore crushers are indispensable equipment in sand and gravel production. Given the varying physical properties and structural differences of ore raw materials, the selection of crushers requires a case-by-case analysis. Although crushers are categorised into primary, secondary, and tertiary types, various models have been developed to better accommodate specific requirements for finished product particle size and production capacity. In daily production, the most commonly employed crushers include: jaw crushers, cone crushers, impact crushers (also termed sand makers), impact crushers, and hammer crushers. With numerous crushing devices available on the market today, selecting an appropriate one not only reduces crushing time and minimises material wastage but also contributes to mitigating equipment wear. Below are the five crushing modes of crushers:

1. Compression Crushing: Material is broken primarily through the gradual increase in pressure between two working surfaces.

2. Splitting Crushing: This type of equipment primarily crushes ore by applying pressure with a sharp edge and a working surface featuring a sharp edge. The ore splits along the direction of the applied pressure line.

3. Flexural crushing: Large ore fragments are broken into smaller pieces through bending forces.

4. Grinding crushing: Ore undergoes relative motion against moving working surfaces, subjected to pressure and shear forces. When shear pressure reaches a certain threshold, the ore is pulverised.

5. Impact crushing: Material is broken by significant impact forces. This method offers high efficiency, large crushing ratios, and relatively low energy consumption.

Production capacity is also a crucial factor in selecting crushing equipment. Generally, higher output requirements necessitate larger equipment specifications, with corresponding increases in both investment and output.
