The outcome of this study can be potentially utilised in the mineral processing industry for plant monitoring and automation Crushed stones should be distinguished by their highest quality
The performance of the stone crushing plant can be judged according to the product quality There are mainly two quality indexes of crushed stone the ratio of elongated and flaky particles and the content of the powder If these two indicators exceed the specified range the product quality is unqualified and cannot be used in large projects
