As for the processing flowchart of river stone, it can be divided into two main stages, including the crushing stage and grinding stage. Firstly, big river stones should be fed into the jaw crusher for primary crushing by vibrating feeder.
After the primary crushing, river stones will be transferred to secondary crushing machine like cone crusher for further crushing. Usually, we will equip the river stone crushing & screening plant with the multi-deck vibrating screen. The vibrating screen is a key equipment to sieve the crushed stones into different grades.
The crushed stone that meet the demands will be transported to the stockpile, the other will be sent to cone crusher for fineness crushing. After the crushing stage, small river stone particles should be treated by the grinding stage to get stone powder or other products. 
River Stone Grinding Machine
As mentioned above, the grinding stage plays a very important role in the river stone processing flowchart. To some degree, the result of river stone grinding can determine the quality of product. River stone grinding machine,refers to the grinding machine used for producing stone powder or other products.
In the stone industry, LM Series vertical mill is often used as the river stone grinding machine. In addition, it is designed with high-performance separator and optimized airflow ensures high separation efficiency and low pressure loss for energy savings.
