China's industrial transformation and upgrading should be in accordance with essential requirements of going the new road to industrialization with Chinese characteristics and building a modern industrial system, taking scientific development as the theme, accelerating development transformation as the main line, and independent innovation and reform and opening up as a driving force, promote the deep integration of informatization and industrialization, foster the growth of strategic new emerging industries, transform and upgrade traditional industries and accelerate the development of producer services, fully optimize the technical architecture, organizational structure, layout structure and industrial structure, establish the industrial development on the basis of innovation-driven, intensive and highly efficient, environmentally friendly, benefit the livelihood and endogenous growth, and continually enhance the industry's core competitiveness and sustainable development capacity to lay a more solid foundation for the industrial power construction and building a moderately prosperous society.

In Hongxing Machinery, stone crushing machine mainly consists of jaw crusher, impact crusher, cone crusher, hammer crusher, VSI crusher and mobile crusher etc. Manufacturing industry directly reflects the level of a country's productivity and it is an important factor to differ developing and developed countries. The manufacturing occupies an important share of the national economy of the developed countries, and the mining machinery industry also occupies temporarily indispensable location in the manufacturing sector. The professional mining machinery manufactures should commit to the exploration and study of the milling equipment and make their own contribution to the development of the manufacturing.


Manufacturing is the main sector of industry. Raymond mill high-end equipment is an important foundation of the development of manufacturing, and also a concentrated reflection of the development of national manufacturing levels. At present, the driving force and the environment of China's industrial development are undergoing profound changes, and Chinese industry has entered a critical period when only speeding up transformation and upgrading can promote development. It is suitable for the medium and fine crushing of all kinds of ores and rocks with different hardness such as iron ore, non-ferrous metal ore, emery, bauxite, perlite and basalt.The final goal and task of ore beneficiation is to separate useful minerals and useless gangue minerals and integrate the useful minerals into independent concentrate, and this process can comprehensively recycle the valuable elements, remove the impurities harmful to the metallurgy and other processing processes and improve the quality of the dressed...

The Good Preparation before the Use of Mining Crusher

The products’ granular property accounts a lot in crusher’s operation, model selection or the next manufacturing and processing as well as flow design and calculation. Elements influencing the granular property: materials’ property, fines content during feeding, the type of a crusher and operation etc. Similar granular property of the gyratory crusher products, it can be selected according to the grain size characteristic curves in the instructions of the gyratory crusher. In Hongxing Machinery, stone crushing machine mainly consists of jaw crusher, impact crusher, cone crusher, hammer crusher, VSI crusher and mobile crusher etc. Therefore, for a better operation of the crusher, Henan Hongxing Mining Machinery will describe the preparations for you before starting.

1.Examining carefully that whether each part is in good condition, all the connectors are tight and obstacles exist in the conveying part.

2.Checking that whether there’s stone or iron ore in the crushing chamber. The foreign substance like ores must be cleared away to make sure that the crusher get started in a non-load condition.

3.Checking the auxiliary equipments such as the feeder, belt conveyer, electric equipment and the signal device that whether they are in good condition.

4.Examining that whether the size of the discharge opening complies with the production process requirement.

5.Examining the oil level and oil temperature in the tank, using heating equipment to heat the oil up to 20 degree when the temperature is pretty low due to cold winter.

6.Checking the lubrication equipment and the interlocks’ condition of the oil pump motor and the crusher motor.


After finished the foregoing inspection and making sure that everything is well-conditioned, then the crusher can be started via the starting procedure. The main shaft is an extreme vital part of the gyratory crusher, it must have sufficient strength and rigidity to ensure a normal operation of the crusher. The foregoing fracture accidents of the shaft told us that they mostly occur in the upper Gewindefreistiche, the lower part matching with the cone and the interface of two different diameters. The factor that caused the fracture is due to the crushing of oversized ores at the discharge opening and too fast discharging.

Clear the Developing Trend about the Mining Industry

At present, there are hundreds of PEW jaw crushers in various types of mines. In order to promote this type of product, the Beijing Mining Research Institute has established Beijing Novi Technology Co., LTD and jointed several famous crusher manufacturers to produce this series products. As early as 1930s, the PJ jaw crusher has reached 1500mm×2100 mm. This PJ jaw crusher has almost no significant changes for the late ten years. The PE compound pendulum jaw crusher is heading for the direction of larger-scale. In the 1960s, the maximum size PE crusher was 600mm×900mm. in the 1980s, PE - 750 mm x1060 mm, 900 mm x1200 mm, and 1200 mm×1500 mm series jaw crusher had been used in the large and medium-sized ore beneficiation plants and non-ferrous mine processing plants.

In the 1990s, the crusher manufacturers at home and abroad had launched 1500 mm×2100 mm、1600 mm×2200 mm large compound pendulum jaw crusher. This jaw crusher has high capacity, lower power consumption, large crushing ratio and uniform size distribution, and has gradually replaced the simple pendulum jaw crusher. Many foreign famous manufacturers such as Mesto Minerals, the former A-C, Kobe Japan, Krupp Germany, Ceda U.S. had not produced the PJ simple pendulum jaw crusher.


In the 1980s, small-case mines in China had developed rapidly; the demand for the crushers exceeded the supply. Due to funding limitations, the small mines didn’t want to choose high-price and difficult to maintenance jaw crusher. In order to meet these needs, many crusher manufacturers in China had introduced a wide range of small jaw crushers. The small jaw crusher had larger width which improved the output, and it was easy to match with ordinary jaw crusher. So that it was very popular in the small mines. The design standard and manufacturing level of Henan Hongxing Mining Machinery Company has reached the domestic advanced level. Professor Wang Hongxun and Mr. Ding Peihong designed the KX series of deep-cavity jaw crusher. Hundreds of devices have been in operation, praised by users.
