Production process of artificial aggregate:
At present, the production of artificial sand is always connected with the production process of crushed stone. During the production of crushed stone, some artificial sand, stone chips or stone powder will be produced accordingly. The artificial sand is obtained through screening, dedusting or water washing. Therefore, the production mode of artificial sand is always connected with crushing and screening. The production methods of artificial sand are as follows:
Two stage crushing, two stage screening and one stage sand making. Stone-coarse crushing - medium crushing - inspection and screening - sand making - graded screening - artificial sand or crushed stone. The sand and stone company adopts this process.
First stage crushing, second stage screening and first stage sand making. Stone - coarse crushing - screening - sand making - screening - artificial sand or crushed stone. The process is used in some key projects.
Two stage crushing and one stage screening. Stone - coarse crushing - medium crushing or fine crushing - screening - artificial sand or crushed stone, this process is mostly used by small and medium-sized enterprises and township enterprises.
Each of the above three process flows has its own advantages. In the process of selecting process flows, attention should be paid to what products are mainly used, that is, artificial sand or crushed stone production. In addition, the designer shall pay special attention to the mesh size of secondary crushing and inspection screening. Because intermediate crushing and inspection screening are the key to the whole process. If not, it will affect the sand making ability in the subsequent process.
Artificial aggregate production equipment.
The production of artificial sand is always connected with crushing and screening. The working principle of the sand making machine is to make artificial sand according to the method of "stone beating stone". According to practical experience, the impact type sand making machine also uses a high-speed rotating rotor to throw materials to the impact plate. The materials broken by the impact bounce back to the plate hammer, and then are thrown by the rotor at a high speed. Some stones are also hit by the "stone hitting stone".
Through repeated collision, impact and grinding processes, until the materials reach the qualified particle size. It can be produced by screening stones and artificial sand of various products. In a word, the process of crushed stone is the process of material changing from large to small and from small to sand. Therefore, the selection of process equipment is very important.
