subject: Crushers Differentiate Due To Different Stones [print this page] The materials after the primary crushing often need fine crushing. In generally, the main fine crushing equipments are impact crusher and cone crusher in the stone production line. Usually we use impact crusher to crush the soft rock such as limestone, for the impact crusher can raise the production and reduce the broken segment. We generally select cone crusher for crushing the medium hard rock.
We must analyze the raw materials and understand its properties and then select the suitable crushing equipment. In general we use two broken segments to crush three level coarse aggregate; use three broken segments to crush fourth level coarse aggregate.
It is understood that, on one hand, as the international market competition is growing and upgrading, the pressure brought by foreign leading-edge technology and market share has greatly stimulated the urgent task of industry transformation and upgrade of domestic crusher. On the other hand, the state has formulated direct or indirect policies to promote the real economy and promote a good atmosphere of the equipment manufacturing industry innovation to build further policy system to support equipment manufacturing innovation, which is gradually guiding the transformation of the crusher industry development model. As a leader of mining machinery industry, Hongxing Mining Machinery is striving to occupy the international market by producing the mining equipment with innovation, such as cone crushers and the impact crusher.
Impact crusher is new and high-efficiency ore-breaking equipment. It is promising equipment with many advantages, such as small volume, simple structure, big reduction ratio (up to 40), low energy consumption, great productive capacity, good finished product shape and selective ore-breaking. However, its biggest disadvantages are its vulnerable board hammer and impact board. Especially when breaking hard ores, they need to be replaced frequently. Owing to the appearance of some wear-resisting materials at present, this series of impact crusher has been used in some concentrating plants.
Cone crusher is suitable for the crushing of materials in the industries of metallurgy, building, road paving, chemical and silicate. It can crush kinds of ores and rocks with the hardness of medium and above medium. Cone crushers have the advantages of big reduction ratio, high efficiency, low energy consumption, and equal granule. It is used in the medium and fine crush of all kinds of ores and rocks.
At present, the competition of Chinas mining machinery industry is very fierce. Henan Hongxing Mining Machinery Co., LTD, as the crushing equipment and sand making equipment professional manufacturer, has found the three main future development directions of crusher industry in the long-term production and sale process.
First, the applications of crusher are more diverse
Second, the requirement of energy saving and high efficiency will improve
Third, numerical control is the new requirement of market.
