The sand making equipment is specially designed for the production of construction sand and road sand. The sand making equipment on the market includes the third generation of sand making machines, and sand making equipment such as pcl sand making machines and vsi sand making machines. In the sand making process, There is a big difference between building sand and highway sand. Shanghai Joyal Mining Machinery here and everyone talk about these two different sand making process, what are the differences.

For construction sand, medium coarse sand is generally used, which is a combination of gravel and stone chips. According to the different flow requirements and pumping requirements for construction, the particle size will be between 10-20mm. Building sands have a very precise requirement on the size of the pellets when processed in a sand machine. Usually, the particle gradation and clay content of sand will cause changes in the properties of the concrete. Therefore, the construction sand requires a lot of strictness in handling the sand machine.

The construction of expressway asphalt pavement requires the use of machine-made sand, because machine-made sand does not have as much mud content as natural sand, which can improve the quality of asphalt concrete pavement. The sand making equipment used on the expressway has a wide range of adaptability and can be widely used in the smashing and crushing of various hard and brittle materials such as rocks, abrasives, and refractory materials.

Different building sands require different sand and aggregate processing equipment. Among them, crushers, sand makers, sand washers, and other sand making equipment are selected by users. Shanghai Joyal Mining Machinery Co., Ltd. Pay attention to the right choice of suitable sand making equipment. As the key mechanical equipment in the sand production line, the choice of sand making machine is very important.
