Abstract

The invention discloses a natural material broken pebble processing system and method. The system and the method are characterized by making full use of the graduation composition advantages of primary rock, controlling generation of granular composition finished materials in strict accordance with the process, breaking the primary rock for at least three times, controlling a breaking ratio, changing the surface areas of primary pebbles in finished particles of aggregates, dominantly generating breaking surfaces and enabling the ratio of the broken pebbles with more than three broken surfaces to be reach more than 90% in the finished aggregates, thereby meeting the requirement of high-performance concrete.

Description

technical field [0001] The invention relates to a processing system and processing method of natural material sand and gravel, in particular to a processing system and processing method of crushed pebbles. Background technique [0002] The natural material sand and gravel processing system, the material source has good grading characteristics, and the conventional process is mainly based on screening and retrieving, supplemented by crushing and balancing the gradation of the finished coarse aggregate. The unit price of finished aggregate is low, and it is the preferred source of sand and gravel aggregate. [0003] In the concrete construction of pavement engineering and bridge superstructure engineering, the strength of concrete is affected due to the combination of the original pebble shape of the finished aggregate of natural materials and the concrete cementitious material. The use of natural raw material sources is limited. [0004] Invent a processing system and metho...
