The Zimbawe Stone Crushers manufacturer explains how to make sure that the crusher finished sand and gravel meet national standards. With the development of economy and society, the market demand for gravel aggregates is increasing. At present, there are more and more enterprises producing sandstone aggregates. So, how can we be sure that the produced gravel aggregates comply with national standards? Here we summarize five aspects:
1. The shape of the particles. The stone crushed by the crusher should be cubic, and the content of needle flakes should not exceed 15%. At the same time, the ratio of the smaller thickness of the needle flakes to the larger length is less than 1: 3. 2. Grading. Grading is an important characteristic of gravel aggregate, which directly affects almost all the important characteristics of the mixture, especially for concrete. The high gradation accuracy can ensure that the Marshall stability and flow value of the concrete are in better design conditions. To ensure the service life of the road.
3. Consistency of particle composition. Consistent particle composition can ensure the quality of the mixture and extend the service life of the road surface. 4. Cleanliness of particles. The presence of excessive dust and other harmful substances on the particles will cause the mixture to peel off and loosen, which will affect the durability of the road surface. 5. The content of particles below 0.075 mm. The content of particles under 0.075 mm in the mixture should not exceed 5% -7%, which can improve its anti-scouring ability.
