River pebble is a hard, wear-resistant and chemically stable silicate mineral. The natural river pebble ore is produced into river pebble sand after a series of processing such as crushing, sand making and screening. It is widely used in highways, high-speed railways, bridges, airport runways, municipal projects, etc.
Natural river pebbles can be directly used only for a small part. Most river pebbles need to be crushed and shaped by a crusher. What kind of crusher is better?
First, the natural river pebble raw materials shall be fed to the jaw crusher through the vibrating feeder at the beginning of the river pebble crushing. Secondly, the second crusher, namely, the secondary crusher, can be used for the medium and fine crushing of river pebbles. However, because the hardness of river pebbles is relatively hard, if the impact crusher is used, the wearing parts will be lost too quickly, the replacement frequency will be high, and the production cost will be directly affected. Therefore, the hydraulic cone crusher can be used as the better choice for the medium and fine crushing with high crushing ratio, high efficiency, and low energy consumption.
The stone after medium and fine crushing is fed into the vibrating screen to separate two kinds of stones, which meet the feeding granularity of the sand machine and are used to make sand, and the other part is returned for fine crushing. Part of the stones of the system sander are made into sand, which is cleaned by the sand washer to make finished sand, and the other part is broken again by the system sander.
