River Pebble Mechanism Sand Introduction
Reasonable river cobble sand making process, while considering the investment cost of the crushing project, can not ignore the production cost of the production line. Considering that the high hardness of the river pebble will inevitably cause high loss to the wear parts such as the slab, the plate hammer and the counterattack plate, in the process design, we recommend the crushing equipment of the lamination principle to reduce the wear of the wear parts. A typical laminating device configuration is a two-stage rupture or rupture plus a cone. If the customer has high requirements for the final stone size, we recommend to configure a sand making machine for plastic crushing, thus forming a three-stage crushing process configuration. The three-stage crushing will inevitably lead to an increase in the investment cost of the project, but for the long-term operation of the sand making plant, the three-stage crushing is very considerable in reducing the production cost. For stone materials such as river pebbles, which are more difficult to break, it is also possible to use a two-stage crushing process that is broken and counter-attacked, but this will inevitably lead to higher hammer loss due to counterattack, shorter hammer life, higher ratio of counter material, etc. The problem, in fact, increases production costs.
Client status
The Zhuhai customer mainly supplies stone and machine sand for the mixing station. The production line is set up next to the river. The equipment is mainly used to produce gravel and sand by using river pebble. The customer has purchased two machine sand production lines from the company.
