As the basic material of engineering construction, sand aggregate is commonly used as cobblestone, granite, limestone, etc. The raw materials are different, and the required crushing equipment is also different.
In the process of processing, appropriate processing equipment should be selected according to different raw materials.
First of all, raw materials can be divided into two categories according to the hardness: hard stone and soft stone.
Hard stone: pebbles, granite, basalt, etc., hardness: 150Mpa or more.
Treatment method: The crushing equipment is usually selected from jaw crusher and cone crusher. It can be shaped according to the requirements of the finished product, and then used by the impact crusher (sand making machine) for shaping. Then, the auxiliary vibrating screen is used for screening, and the crushed materials are classified into finished aggregates of various specifications.
Soft rocks include limestone, sandstone and others, with a hardness below 150 MPa.
Treatment method: The crushing equipment can adopt jaw crushers, cone crushers, heavy hammer crushers, or impact crushers (sand making crushers) according to actual needs. Important note: Limestone varies greatly in hardness depending on its silica content. High‑silica limestone requires a cone crusher for crushing.
There are many ways to select the sandstone aggregate processing equipment and process design. Specific model selection and process requirements shall be determined based on the hardness, bulk density, mud content, finished product specifications and other characteristics of raw materials. When assigning solutions to customers, we will go to the site to configure the appropriate equipment according to the material conditions, so that you have no worries in the production process.
