In the past decades, the river sand is a main source of building materials used in producing concrete. However, along with the overexploitation in recent years, many entities and individuals are now forbid to exploit the river sand. Under this condition, many enterprises turns their focus to the artificial sand that is made of river pebble or other rocks. In order to process original river pebble or rocks, we have to build a crushing line to process the rock into sand, which is called sand-making line. For many enterprises, it is often their first to get in touch with sand-making line. Hence, they have no idea about how to build a new sand-making line. In order to help you who want to start a new sand-making line, I will share with you next about how to design two basic types of sand-making line.
1. Basic sand-making line for rocks
If the raw material is not the river pebble like limestone, basalt, granite stone, marble stone, etc, the basic sand-making line should consist of three crushing stages. The first crushing stage should be the primary jaw crusher, the second crushing stage is the cone crusher, and the tertiary crushing stage will be the VSI crusher or gyratory disc crusher. This basic type of sand-making line can easily reach a capacity of 200TPH, which means it can satisfy most of the requests.
2. Basic sand-making line for river pebble
If the raw material is the river pebble that contains a certain amount of river sand, we have to add a pre-screening step before crushing work. Compared to the above sand-making line, this crushing line has the same crushing stage design and the same crusher machine choice as well. The only difference is to add a vibrating screen in to do the pre-screening work before the first crushing stage.
Ok, the above is all about how to design a sand-making line to produce artificial sand. The above two types of crushing are just the basic design to achieve a capacity of 200TPH. If you have special request for increased capacity, we can just add crusher machine into the corresponding crushing stage. In the following articles, I will continue to introduce the crushing layout design for ceramic crushing lines.
