As we all know, the coal dug from the earth or underground is screened and processed to remove the gangue and iron pyrite, then the final product is raw coal. And also, the raw coal includes the coal produced without any special treatments such as washing, screening, and processing. While, there is also one kind of coal who is produced with the raw coal process, but it doesn’t belong to raw coal, so we call it coal gangue.
But no matter which material we want to crush, raw coal or coal gangue; if we want to choose the most suitable crushing equipment to apply, there are many aspects we should take consideration.
As for raw coal, the moisture content decides the equipment directly. While,as for coal gangue, the size of the raw material of coal gangue certainly influences our choice.
Raw coal crushing equipment choice
If the moisture content is less than 10%, we should choose the PCH ring hammer crusher. As a type of hammer crusher, this equipment is applied for non-cohesive material crushing, and its moisture content should be less than 10%. It can be used in raw coal crushing production line and sand making production line. In addition, it can replace the cone crusher in a beneficiation production line. And it is suitable for moderately hard and weak corrosivity material crushing, such as gangue, coal, salt, chalk, gypsum, tile, limestone, coke, red sandstone, slag, shale, etc.
If the moisture content is more than 10%, we should choose a 2PG roller crusher. As a type of roller crusher, it is suitable for primary and secondary crushing, and the moisture content of material is more than 10%. They guarantee a strictly defined final grain size with a minimum of fine grains. It is used to crush coke, sinter, coal, soft to medium-hard rock, ore, chalk, broken glass and similar products.
Coal gangue crushing equipment choice
If the size of the raw material of coal gangue is more than 80 mm, the DPX single-stage fine crusher is your best choice. This type of crushers is suitable for moderately hard and easily breakable material crushing, and its mok’s hardness is less than 150 Mpa. It features transforming the 2 stages crushing process into 1 stage to reduce the cost and make the whole operation easier. In addition, it also can reach a magical effect of “more crushing and less wearing”.
If the size of the raw material of coal gangue is less than 80 mm, we can select a PCK reversible hammer crusher. It can be called a type of special equipment just for coal gangue crushing. It can be applied the moderately hard and easily breakable material crushing, and the material Mok’s hardness is less than 120 Mpa. And it is famous for its three main advantages: 1. Roll hammer crusher and impact crusher into one. 2. It has the powerful “tertiary crushing cavity” to crush the material more efficiently. 3. The super wear-resistant material “big gold tooth” crusher hammers are its main crusher parts, which makes the spares service life last more than 17 months. Among these features, the last one is its biggest advantage.
