The river pebbles are generally taken from the sand and gravel hills produced by the uplift of the ancient riverbed after the crustal movement thousands of years ago. They have experienced the impact of mountain torrents and the continuous squeezing and friction during the process of moving water. In the process of tens of thousands of years of vicissitudes and vicissitudes, they have experienced the movement of waves and water, and they lost their irregular edges and corners by the collision and friction of gravel. The surface is smooth and the average content of SiO2 is 85%. Mohs is above 7 degrees, with good compression resistance, wear resistance, and corrosion resistance. It is an ideal and widely used machine-made sand material.

 

The process flow of river pebble processing:

1. The original material passes through the silo, is fed evenly by the vibrating feeder, and is conveyed to the jaw crusher for primary crushing. The material after the primary crushing and the fine materials sieved by the vibrating feeder are conveyed together by the belt conveyor. Transfer stockpile.
2. Conveyor belt conveyor transports the materials from the transfer pile evenly to the cone crusher for medium and fine crushing. After crushing, it is screened by the circular vibrating screen. Larger particles are returned to the cone crusher to be crushed again; medium-sized materials are sent to the sand making machine for fine crushing and shaping; the qualified materials of the particle size are cleaned by the sand washing machine as the final product.
3. After the medium-grained materials are sent to the sand making machine for fine crushing, they are screened by the circular vibrating screen. The larger-grained materials are returned to the sand making machine and crushed again. The qualified products are sent to the storage pile by the belt conveyor for storage, and the fine materials are sent to the sand making machine. Sand washing machine cleaning.
4. After being cleaned by the sand washer, the materials sent to the sand washer are transported to the storage pile by the belt conveyor as part of the final product.
