A complete sand and gravel production line is composed of equipment of different models and specifications, and the output is mainly related to the selection of configuration plans and equipment models. With the development of infrastructure in various places, the demand for sand and gravel materials is increasing day by day, and the price of sand and gravel is also rising again and again. Coupled with the limited mining of river sand, many places encourage and support the development of the machine-made sand industry. Then, correspondingly, the process and equipment configuration of stone production have attracted much attention.
Under normal circumstances, the type and hardness of the crushed stone master batch should be considered first in the configuration of the crushed stone production line, whether it is limestone, granite, pebble or basalt, the hardness of the rock (the rock with a Mohs hardness above 7 is very hard), and the rock whether it is soft brittle or hard brittle type, soft brittle crushing does not require a high soldering iron crusher, high manganese steel, such as jaw crusher, impact crusher, etc.; hard brittle crushing requires high soldering iron crushers, such as cone crushers and plastic crushers. The second is to consider the performance (crushing ratio) and applicability of the crusher. The jaw crusher has a large crushing ratio, squeezing and crushing, and the discharging material has many needles and flakes, which is suitable for coarse crushing; impact crusher, plastic crusher products good grain shape, suitable for medium crushing and fine crushing; impact crusher and hammer crusher are suitable for crushing medium-hard and below-hard stones, and cone crusher and shaping crusher are suitable for crushing medium-hard and above-hard stones. Once again, the output is considered, which requires better matching between equipment. Finally, consider whether there is a special quality requirement standard for the crushed stone. If the crushed stone has a high requirement, it needs to be shaped and a shaping crusher should be equipped.
