Overview of cement sand and crushed stone grades

Henan Liming Heavy Industry Science & Technology Co.,Ltd. (formerly Henan Liming Road & Bridge Heavy Industry Co., Ltd.) manufactures various equipments for a whole set of cement sand and crushed stone grades, and provides complete technical support for customers. The whole cement sand and crushed stone grades consists of vibrating feeder, jaw crusher, impact crusher, vibrating screen, belt conveyor, electric control, etc. We design different production lines ranging 50 t/h to 500 t/h by combining different models of equipment which can match cone crusher, deduster, etc. If necessary to satisfy different customers’ technological requirements. It is widely used for crushing hard limestone, granite, basalt, gravel, metallurgic slag, etc. Or artificial sand making for hydroelectric power, building material, high way, city construction, etc. Different models of machines are combined to meet different customers' different demands according to different craft requirements.

Working Principle of cement sand and crushed stone grades

Big size stones are transferred to primary crusher through vibrating feeder from hopper for first crushing, then the crushed materials are transferred to impact crusher through belt conveyor for secondary crushing. The materials crushed will be transferred to the vibrating screen, and separated to different sizes. The aggregate with suitable size will be transferred to the final product pile and aggregate with unsuitable size will be transferred to the impact crusher for re-crushing. This forms a closed and manifold cycles. The sizes of final products will be graded and separated according to customers' requirements, and the duster will be attached for the sake of environment protection.
