<p>At present, due to the excellent advantages such as the flexible adjustment of the particle size and wide range of adjustment, the aggregate jaw crusher is favored continuously by different users. The aggregate jaw crusher developed by our company, after the continuous research and practice, the performance advantage is more prominent, which greatly enhances the efficiency of the sector. In some areas, the industrial waste, construction waste and waste rock are processed to form the stone production line through the crushers to realize the large-scale production of artificial gravel. In recent years, the industry has become a new area of investment. The sand and gravel is also called construction aggregates, which is mainly used for engineering infrastructure construction, concrete, mortar and the corresponding products. In order to further improve the quality and to provide customers with satisfactory equipment and to meet the market needs, our company positively conduct the technology R & D, and introduce the production and technical experience of the foreign equipment to develop Ultrafine Mill , which has significant performance on the production and supply of the aggregate that is used in the highway and high-speed rail as well as the crushing of the construction waste. It is favored by the majority of customers. The performance advantages of the new aggregate jaw crusher can be shown in the following areas:1, the crushing chamber is deep, which increases the feeding capacity and output 2, it has large crushing ratio and the particle size is uniform; 3, it is reliable and convenient, the adjustment range is wide, which increases the flexibility of the device;4, the lubrication system is safe and reliable, maintenance workload is small; the operating cost is low.</p>
