With the development of the national infrastructure projects in recent years, China's investment in infrastructure including road construction has stimulated the development of construction machinery industry. It is understood that China had completed the task of 2.5 trillion fixed assets investment , including 800 billion yuan on railway, 1.5256 billion on highway and 0.1458 billion on waterway.

Along with the implementation of "One belt, one road", Yangtze River economic belt, Beijing-Tianjin-Hebei region coordinated development strategy, the investment on the transportation and other infrastructure will continue to rise in 2015. Therefore it will bring a new round of development opportunities for the mining machinery enterprises, the sand and gravel plant, road and bridge machinery, promote the rapid development of the construction machinery industry.

The infrastructure construction is based on the support of gravel aggregate and the input of the cement, while the gravel aggregate and cement production depend on the crushing equipment and cement production line. From a certain point of view, the infrastructure greatly stimulate, promote the rapid development, and bring a new opportunity for the construction machinery industry including the mining machinery industry.

Henan Zhengzhou mining machinery Co., Ltd. (referred to as: ZK) is the appointed manufacture of cement building materials, crushing and screening equipment by National Machinery Industry Ministry, integrating scientific research, design, development, manufacture, sales, installation, test and training services. Crushing and cement production line equipment have good sales in various provinces and regions, have been exported to Russia, Turkey, South America and other countries and regions, which also have received good reputation from customers.

PF series impact crusher is a new highly efficient impact crusher with developed by Henan Zhengzhou mining machinery Co., Ltd., based on the absorption of foreign advanced models. Compared with other types of crushing machine, it has a large feed granularity, suitable for all kinds of materials crushing with the compression with no more than 320Mpa. It has the advantages of unique structure, convenient operation, high efficiency, discharge material at cubic shape, size adjustable, and optional broken, etc.. PF impact crusher crusher can be widely used for crushing various materials in the cement, building materials, chemical industry, metallurgy, electric power and other industries, especially suitable for the construction aggregates crushing in highway, railway, nuclear power plant, water conservancy and other special industry, such as the crushing of basalt, andesite, gravel, granite and other materials.

The working principle of the PF series impact crusher: the motor drives the rotor rotating through the triangle belt with high speed, while the material enters the crusher chamber from the feeding part, is impacted by the high speed rotating rotor and and broken by the impact of the vortex. The bulk material that has not been fully broken produced tremendous pressure and bending force under the affect of crushing cavity thick toothed plate and the plate hammer. Even the material that difficult to crush can easily be coarsely crushed into the lower segment S crushing cavity and T crushing cavity, and materials will be in secondary crushing and fine crushing process in the crushing cavity by friction, extrusion, impact, fracture, and then discharged out of the machine.
