Basalt Crusher Process Configuration

Overview

Basalt and diabase are relatively high in hardness and high in silicon content, and are difficult to break in actual crushing operations or have high crushing costs. In general, basalt and diabase are hard and tough materials with high silicon content. Therefore, the crushing process of basalt/diabase should be designed reasonably. When considering the investment cost of the crushing project, the production cost of the production line must be considered.

In the actual crushing operation, some customers’ raw materials are limestone, the broken slab loss is very low, and the life of a pair of slabs is very common for one year. This is because limestone is not only very low in hardness (grades 4 to 5), but also has a low silicon content in the stone and is very abrasive to the wear parts of the crusher. The raw material is the crushing operation of basalt/diabase, and the wear of the wear parts such as the slab, the plate hammer and the counterattack plate is very high. The production cost of the customer is much greater than the production cost of limestone. Therefore, for the design of the crushing process, we should use the crushing equipment of the lamination principle as much as possible to reduce the wear of the wear parts. A typical laminating equipment configuration is a two-stage rupture or rupture plus cone-breaking process configuration. If the customer has higher requirements for the final stone size, we can configure a counter-breaking to complete the type of crushing, thus forming a three-stage crushing process configuration. The three-stage crushing will inevitably lead to higher investment costs for the project, but for the long-running stone plant, the production cost of the three-stage crushing reduction is considerable. Below are some basic basalt process configurations, please see. Each configuration method has its own characteristics, and the specific design should be analyzed according to the actual situation of the customer.

Basalt is used in many stone yards where the grain size of the stone is not high. The user is willing to use a jaw crusher, a fine jaw crusher/spring taper to form a production line. Because the smashing and the spring cone breaking are both lamination principles, the wear of the wear parts is relatively small, and the production cost is relatively low. However, due to the lamination principle, the crushed stone material type is not so good, the content of the needle-shaped stone material is relatively high, and the internal crack of the stone material is relatively serious, which is unwilling to accept by the building, so the market price is more than the counter stone.

If the market has certain requirements on the grain size of the finished stone, and the user wants to reduce the cost per ton of the wearing parts, it can be considered that the rough and broken, fine broken/cone broken as the head break and the second broken, the impact crusher is placed in the first In the three broken positions, it mainly serves the purpose of shaping. This not only reduces the wear and tear cost of the counter-attack, but also obtains a good grain of stone. The specific process configuration needs to be analyzed according to the actual situation on site.
