Crushers are extensively used in mining, metallurgy, building materials’ making, road construction, railway construction, water conservancy construction and chemical engineering, etc. Due to the growing need for raw materials along with the economy advancement and also national protection for non-renewable resources, there’s a increasing demand for crushers. Jaw crushers are generally applied in primary crushing link as they have very strong crushing capability, and they can ensure the sizes and uniformity of the crushed materials. Hence, they are often used in mines and smelting. Of course, such type of crusher has very simple structure. It is convenient to repair them. So they are deemed to be the most economical crushing equipment.Some may think that crushing machines themselves are ones working in mining industry, why do some people say such machines also should pay attention to environmental protection? If we say from the influence of products themselves on environment pollution, we mainly say that they have smaller influences on environment as they save energy. If there is too much energy consumption, particularly in the situation of electric energy and petrol consumption, environment will be affected. Efficient crushers can achieve the purpose of protecting environment from the aspect of energy conservation.
Cone crushers are primarily applied in secondary and tertiary crushing, suitable for tinier crushing. Owing to more elaborated operation requirements, their structures are relatively complicated. Daily maintenance should be paid attention to for purpose of reducing maintenance. But as a matter of fact, the really important part is whether mechanical equipment pollutes gravels or not. For example, traditional machines are likely to make some iron elements mix in gravels when they are impacting owing to structure cause. This is iron pollution that people often say. However, new crushing machines can avoid iron pollution for such machines themselves are cube. Hence, they are very safe.
