Gravel aggregate is an indispensable and important raw material for infrastructure such as construction, bridges, highways, railways, etc., and its amount is large and irreplaceable. The annual market demand is continuously increasing. During the 'Twelfth Five-Year Plan' period The annual output has reached more than 20 billion tons. Statistics found that there are more than 20,000 domestic sand and gravel processing plants, and more than 50% of mining enterprises fail to reach 500,000 tons of annual output. Their small scale of production and low industrial concentration occupy the dominant position in the industry, and the situation urgently needs to be changed. .
At present, some domestic enterprises have a low utilization rate of ore resources. One of the main reasons is the low degree of mechanization and automation of production equipment (Portable Impact Crusher Plant For Sale In Indonesia , sand makers, etc.). In addition, it also includes the imperfection of the industry management system. Therefore, it is necessary to increase the innovative production and technological innovation of sand and gravel processing equipment, improve its efficiency and effect, and produce better sand and gravel aggregate.
