A review on developing course of jaw crusher

With the continuous development of modern industry, the various types of crushing equipment develop very rapidly at home and abroad. The specifications of the crushing equipment become more abundant. The crushing mechanism becomes more mature. The mere static crushing, impact free crushing and squeezing crushing have gradually developed into the high-pressure, high-energy and high-efficiency crushing with complex mechanism. This article will describe several common crushing equipments and review the development of the jaw crusher.

The jaw crushers produced by different enterprises have different characteristics, size specifications, models, performance and output. In the applications of the jaw crushers, the simple pendulum jaw crusher and the compound pendulum jaw crusher are used most widely. The operation and adjustment is more convenient and the repair cycle and service life is extended. In addition, the crushing efficiency and production capacity is significantly improved. The compound pendulum jaw crusher has significant technical characteristics after transformation.

In terms of Chinese steel industry, at present, the international level is very low. For example, South Korea Pohang is vigorously expanding the Southeast Asian market, but the other way around, Baofeng Steel Company, the first one in China took action to build factories in Brazil in 2007, it was finally declared mortality. Indeed, while China’s economic slowdown, this year it is still expected to maintain high growth of over 9%, not a low figure. In fact, it is the growth pattern that more important than the growth figures. For these years, iron ore price has been higher and higher. In addition to mining monopoly, the situation should also be blamed to Chinese big appetite. At any rate, this will impact China mining industry to a certain degree.

The simple pendulum jaw crusher produced by Henan Hongxing Mining Machinery has the separated structure. The jaw crusher is connected by the screw or pin. The bearing spindle and moving jaw use the sliding bearing. The thin oil is used as the lubricant. The equipment is controlled by the hydraulic system. In order to meet the needs of the factories, mines, building materials, road construction and mineral processing, Henan Hongxing Mining Machinery continuously innovate and develop more new crushing equipments.

The manufacturing technology in recent years has gone through the three stages. The stages can be divided into the imitation of the foreign advanced equipment, improvement and self-design. At present, the domestic jaw crushers have basically reached the internationalization and have formed the product line. The update and design make the structure and performance of the equipment more rationalized and advanced. In the update and design of the compound pendulum jaw crusher, Henan Hongxing Mining Machinery appropriately reduces the hanging height of the moving jaw, increases the volume of the crushing chamber, narrows eccentricity, reduces tooth angle, installs the screw or the hydraulic adjustment device and improve the shape and materials of the liner (pad) so that the trajectory of the movable jaw is more reasonable.

Henan Hongxing Mining Machinery Co., Ltd has many years’ of technological power and experience accumulation of manufacturing and management of hammer mill crusher, portable crushing plant which have many advantages such as simple and reasonable structure, high independent impact crushing ability, super low operational cost and the most competitive price. These machines have the most competitive price and the most reliable quality so that they are the top choice for the high performance crushing equipment.
