The advent of the jaw crusher was in 1858 with 100 years of history. In order to meet the customers’ demand, the manufacturers continuously improve and innovate the equipment structure. The performance has been greatly improved, but there is no fundamental change of the basic principle which still basically belongs to the static extrusion broken. The jaw crusher produced by different enterprises has different characteristics and size specifications, models and performance. Most mechanical plants mainly produce the small and medium-sized jaw crusher. The jaw crusher is mainly divided into the simple pendulum jaw crusher and the compound pendulum jaw crusher. The manufacturing technology in recent years has experienced three stages of imitation with the similar equipment, improvement and self-based sauce. The jaw crusher has basically reached the localization and the formation of a product line. Particularly the updating the design of the structure and performance makes the equipment more reasonable and advanced. In the process of update and the design of the compound pendulum jaw crusher, Henan Hongxing Mining Machinery appropriately reduces the suspension height of the moving jaw, increases the the crushing chamber volume, narrows eccentric distance, reduces tooth angle with screw or hydraulic shim adjustment device to improve the shape and materials of the lining (pad) so that the trajectory of the moving jaw is more reasonable. The motor drives the belt and belt pulley to make the moveable jaw move through the eccentric shaft. When the moving jaw is up, the angle between lining plate and moving jaw becomes large, and this will push moving jaw plate close to the fixed jaw plate. The adjust operation is more convenient and the maintenance cycle and service life may be extended. The crushing efficiency and production capacity were significantly improved with significant technical characteristics. This series of jaw crusher have many advantages, such as big crushing ratio, even granularity, simple structure, reliable working condition, convenient repair and economical operation. They are widely used for crushing minerals, smelting, building materials, chemicals and other materials. In recent years, the energy has become scarce. In order to meet the requirements of the fine crushing operations of the building materials, road construction, mineral processing, chemicals and electricity, the beneficiation and grinding strives to increase and save energy. Henan Hongxing Mining Machinery Co., Ltd. has formed a series of primary jaw crusher and the development prospect is optimistic.
