Crushing process of tunnel slag sand making machine

A large amount of slag is inevitably generated during tunnel construction. To deal with these slag, a large amount of permanent land needs to be requisitioned, and a lot of transportation costs will be incurred in the process of discarding slag. In tunnel construction, the demand for concrete is large.

The use of tunnel slag tunnel slag sand making machine, tunnel slag tunnel slag sand making machine and other sand and gravel equipment to process tunnel slag to produce sand and gravel aggregate can not only reduce production costs, but also promote the comprehensive utilization of tunnel slag resources, which is beneficial for tunnel engineering. , highway, high-speed rail and other projects to provide strong equipment support.

The grade of the surrounding rock of the tunnel determines the integrity of the surrounding rock, but the rock type of the surrounding rock is the key parameter that determines whether the crushed stone can be prepared. The grade of the surrounding rock is mainly determined by the crushing degree of the slag and the type of the surrounding rock. The slag with a low grade of surrounding rock may not necessarily have low rock strength, and the slag with a high grade of surrounding rock may not necessarily meet the requirements for preparing sand and gravel materials. Practice has proved that IV/V The basalt of the grade surrounding rock can meet the specification requirements as the raw material of sand and gravel.

Analysis of tunnel surrounding rock types and grades -> analysis of supply and demand of slag and sand and gravel -> selection of gravel yard site -> selection of machinery and equipment for gravel yard -> construction of gravel yard and installation of machinery and equipment -> sand and gravel quality inspection -> Mechanical equipment adjustment. During the working process of the sand making machine, the plunger fuel injection pump is driven to supply high-pressure oil to the system through the rotation of the cam device.

The use of abandoned tunnel slag to prepare sand and gravel materials solves the problem of lack of local sand and gravel resources, saves waste slag sites, and builds green projects. By adjusting the parameters of the mechanical equipment, the sand and gravel materials that meet the requirements of the specification and the actual use requirements are prepared.
