The sand and gravel aggregate production should be more focus on energy efficiency and environmental protection. Economy is accompanied by increased levels of resource consumption and environmental destruction, industrialization which must weigh the pros and cons, how to increase the economic development taking into account energy saving it? Advanced technology, high-end production equipment for the production of a strong guarantee.the eccentric shaft speed. In a certain range, the eccentric shaft speed increases, crusher will be a corresponding increase in the pe jaw crusher. When the movable jaw swing beyond a certain limit, then increase the speed, the power will be rising rapidly.

Because the eccentric shaft speed is too high to make the broken good material to wait by the discharged, it will cause the energy consumption.sand and gravel aggregate production should focus more on high quality. Recent frequent domestic building tilt, bridges collapse and other incidents have been to all builders and materials manufacturers sounded the alarm, it relates to not only the country's economic losses, it is the people's lives and property.

Therefore, no matter what kind of equipment should first guarantee is that the production of material must have a good quality of this off.The physical and mechanical properties of materials. This is a factor of great influence on the power of small jaw crusher, including material hardness, strength, moisture, viscosity. If the hardness or the strength of material is higher, then the crusher in the implementation process of crushing operation, do great work to complete, so the higher power.

Jaw crusher is widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry in a variety of ores and medium-grained bulk materials broken. The maximum compressive strength of the material to be broken is 320Mpa.mobile jaw crusher manufacturers have produced a lot, but at this stage the country's infrastructure construction has a higher production equipment requirements.
