River pebble sand production line
Analysis of the composition of river pebbles:
River pebble is a kind of pure natural stone, which is taken from the sandstone mountain produced by the uplift of the ancient river bed after the crustal movement thousands of years ago. In the course of thousands of years of vicissitudes and evolution, they have experienced the movement of waves and water, and the irregular edges and corners have been lost by the collision and friction of gravel, and finally become hard quality, bright and simple, compressive, wear-resistant and corrosion-resistant river pebbles. An ideal green building material.
Equipment needed for river pebble sand making:
River pebbles are relatively hard, but have the highest silicon content. Therefore, the crushing process for river pebbles should be reasonably designed. While considering the investment cost of the crushing project, the production cost of the production line must also be considered; in the crushing operation of river pebbles, the jaw The loss of wear-resistant parts such as plates, blow bars, and impact plates is very high; therefore, in the design of the crushing process, crushing equipment based on the lamination principle should be selected as much as possible to reduce the loss of wear-resistant parts; typical lamination equipment configuration It is a process configuration of two-stage jaw crusher or jaw crusher plus cone crusher; if the customer has higher requirements for the final stone particle shape, an impact crusher can be configured for integral crushing, thus forming a three-stage crushing process. Configuration; three-stage crushing will inevitably lead to higher project investment costs, but for long-term operating stone factories, three-stage crushing can greatly reduce production costs; for stone materials that are difficult to crush like river pebbles, it can also be used Two-stage crushing process of jaw crushing and impact crushing.
