The Improvement of Performance Level of Jaw Crusher and Mill

According to statistics, about 30% of sand maker is applied in the cement industry and the mining industry. China economy grows steadily. The construction of the West and the Central Plains needs large amount of sand, which will inevitably promote the development of sand maker. It is predicted that the sand maker industry will have broad market prospect over the next ten years.Third generation sand maker has a shaping function, the product formation of square-shaped, the bulk density can be used for stone shaping, and in the production process, the stone can be formed protection layer, and the device body has no wear and it is durable.The hydraulic efficient cone crusher, VSI sand making machine, 5X series sand making, the HCS90 efficient cone crusher, R-type tilting Mill (Raymond Mill), high pressure mill, high pressure micro powder S ultra-fine grinding mill, medium speed trapezium mill, high pressure hanging roller other products are suitable for airports, railways, highways, ordinary highway construction, national large bridge and undersea tunnel, land tunnel, the new high-rise buildings and other buildings.Simplified grinder mill cracking is generally caused by two reasons: the first is of poor quality welding itself or simplified quality does not meet the requirements of steel, bending strength is not enough, fatigue fracture; second is to improve the production process, after loading the mill, so that the force plate over simplified design specifications, or other reasons caused by overload breakage or cracks simplified. There may be due mill Simplified internal stress caused by temperature changes greater damage. Some ball mills use a longer period, as simplified in severe wear of individual parts, can also cause Simplified strong enough, cracks.Processing methods are:(1) cleaning cracks at the plate, find the cracks of the two endpoints at the endpoints of the 5 ~ 6mm drill a hole, make up the hole, avoid the cracks continue to extend.(2) air gun or...
