Zhengzhou Huayang Machinery Equipment Co., Ltd.

In highway construction, high requirements are placed on the particle shape and gradation of concrete sand and gravel aggregates, especially the needle-flake content in basalt (diabase) gravel. In order to solve the requirements of particle size and gradation, particle shape, consistency of particle composition, cleanliness and particle content, Huayang added a new sand making machine to the production line configuration to better meet the requirements of highway cement, asphalt, etc. Requirements for sand and gravel aggregates.

Introduction to sand and gravel aggregate for highways
Highway construction has put forward very high requirements for the particle shape and gradation of concrete sand and gravel aggregate, especially basalt ( Needle flake content in diabase) gravel. In order to solve the requirements of particle size and gradation, particle shape, consistency of particle composition, cleanliness and particle content, Huayang added a new sand making machine to the production line configuration to better meet the requirements of highway cement, asphalt, etc. Requirements for sand and gravel aggregates.
Highway aggregate production process
The mined stones are first fed to the jaw crusher by the vibrating feeder for preliminary crushing. The secondary crushing is completed by the cone crusher, and the materials broken out of the cone are put on the vibrating screen. After screening, the larger materials are returned to the cone crusher for re-crushing, forming a closed loop, and the smaller materials enter the vertical impact crusher for shaping and crushing. Materials broken out by the vertical impact crusher are screened on the finished product screen. Materials that are larger than the size are returned to the vertical impact crusher for cycle crushing. Materials that are smaller than the size are transported to each finished product pile by a belt conveyor.
