The quality of the product is always placed in the first . Gravel production equipment in general , including the crusher , feeder, sand making machine , vibrating screen , Stone crusher is the core of the entire sand and gravel production process . Stone crusher  into the host with wear spare parts of crusher wear spare parts is the soul of the crusher . At present, many small businesses in order to maintain the livelihood of plagiarism to mimic a variety of crushing equipment and spare parts wear , not only the overall quality of the crusher greatly reduced , but also restricted the pace of progress of the entire crusher industry .

Extension of the gravel industry chain , to increase the value-added products , sand and gravel industry , an extension of two -pass , to go up to the mining direction to the development of machinery, manufacturing ; advance down to the commercial concrete , construction , upstream and downstream there is large room .

It is understood that on the 30th anniversary of China's Association of gravel , experts say that the three major goals of surface sand and gravel industry to develop a resource conservation and development mechanism sand . Production of natural sand and sand 50% , with the reduction of the natural sand resources and meet the need for environmental protection , the trend of the future is the development mechanism of sand -based . Second, the technical efficiency , in-depth industrial construction sand and gravel industry leader in terms of factory operation , equipment, mechanization level , degree of automation has made great achievements .Extension of the chain of sand and gravel industry , increase value-added products , extension of sand and gravel industry is a two -pass , to go up to the mining direction to the development of machinery, manufacturing ; down to advance to the commercial concrete , construction , upstream and downstream there is large room .

Sand and gravel industry in China to accelerate the pace of industrialization will inevitably bring about the industrial structure adjustment and upgrading of gravel industry . As a result, has been indispensable in the production process of the mechanism of sand and gravel , sand and gravel machinery industry will usher in an unprecedented development opportunity : to believe that the practice confirms the good quality crusher equipment , sand making equipment , screening equipment , transportation equipment and less dust devices , etc., will come in handy .
