Machine-made sand is made of materials of different hardness, processed by crushers and sand making machines. To produce good machine-made sand, three conditions must be met.
Select qualified stones The raw materials that can be used to process machine-made sand are: river pebbles, granite, bluestone, granite, basalt, dolomite, construction waste, etc. The quality control of machine-made sand should be selected and controlled from the selection of raw materials to produce sand and gravel aggregates that meet the regulations.
Choose a suitable sand making machine Sand making machine is the key to processing good machine-made sand. There are a wide variety of sand making machines on the market. Different sand making machines have different technologies and principles, and different sand particle sizes.
Choose a suitable processing technology In the process of machine-made sand production, the production equipment and processing processes of different materials are different, but the general production process is the same, generally divided into five stages: pretreatment-crushing-sand making-screening-sand washing (powder selection).
