Under normal circumstances, the gravel particle size by sieve size to ensure that the shaker screen to meet the specifications of the particle size by the type of shaker, installation angle, the screen surface area, and operating conditions, and restrictions. Gravel gradation adjust the crusher discharge opening size and the screening efficiency vibrating screen (screening efficiency and size of the impact of gravel to ensure the quality of gradation). Elongated particles adversely affect the liquidity of the concrete, affect both the gravel and sand, cementitious materials such as bond, is harmful to concrete things. Due to a variety of specifications, the engineering is generally believed that the flakiness in the gravel particles (elongated particles hereinafter referred to as A) content shall not exceed *5%, and even less the better view. But, in fact, is not the case, on the one hand, transferred from hand to mechanized production of crushed stone, A, will inevitably become more content, especially high-strength gravel; the other hand, the test also overturned the view of the above test to prove A content in the gravel from *0% to *0% best It is not obvious deterioration of the concrete mixture workability and physical properties, but also improve the strength characteristics of concrete. Control the flakiness content,jaw crusher plays a vital role.
