Concrete Market Promotes the Development of Crusher
Since the beginning of 2012, the real estate industry has been shrinking, various infrastructure projects slow down development pace, such as railways, highways and other projects, however, in this background environment, the concrete market is still hot. Preparation of concrete needs fine aggregate and coarse aggregate; these sand, stone skeleton from play a support role for concrete, are essential building materials; besides cementitious materials, physical and mechanical properties and durability of concreteto a considerable extent depends on the sand and gravel aggregate.
Sand and gravel aggregate grain divided into the gravel and sand according to shape and size, they are closely related to the quality of concrete. Generally, if it is a small project with aggregate, we can procure to the nearby small quarries or stones factory, but in the country's infrastructure project, the required gravel aggregate is not only large, and quality requirements are very strict, and general small quarries can not meet the large-scale infrastructure projects demand on sand and gravel, then they need to configure sand and gravel machinery and equipment business gravel production lines to open up mines, tailings production of gravel and sand. It is learned that a growing number of project contractors have begun the construction of the aggregate production line equipment, building sand production equipment, to bring the great development of gravel machinery industry.
Gravel production line differs with sand production line. Sand production line is mainly to make sand, key equipment is sand maker; gravel production line is mainly to process pebble stone, the main equipment is the impact crusher and hammer crusher. According to market research, various types of impact crusher has been very common, among which Zhengzhou Hongxing crusher is with high-yield, high-performance, low power consumption characteristics by the best evaluation. Zhengzhou hongxing gravel project also gives this explanation: add powder of the proportion below 15%, the concrete will be very useful to promote concrete performance, but must not be pink high rate, otherwise it will affect the quality of the concrete, and even affect the quality of construction projects and livelihood of people. Gravel production line machinery and equipment industry is going high-speed development, but our gravel machinery and equipment technical level still to be improved, the state should encourage the efficient development of aggregate production equipment and take the necessary steps to obtain sand and gravel industry, high-yield, low energy requirements of the development, to avoid the production of sand and gravel aggregate not meeting construction sand standards.
