1. Technical principle of machine-made sand equipment: the material enters the high-speed rotating impeller crusher from the silo at the upper part of the machine, and the material collides with another part of the material reflected around the crushing cavity to form a crushing curtain, which does not contact with the crushing cavity quickly; After the materials collide with each other, the impeller and the materials collide with each other in the crushing cavity, and the materials are crushed by mutual friction; The crushed materials are directly discharged from the lower part of the crusher, forming a complete multi-cycle; Finally, the granularity specification required for the finished product is controlled by the screening equipment.
2. Precautions for the operation of machine-made sand equipment: There are many operations of sand making machine, such as normal start-stop sequence, feeding sequence, adjustment of discharging size, observation of power and current, and maintenance and observation of abnormal phenomena during the operation of sand making machine equipment. These operations have a great influence on the production of machine-made sand and need to be carried out in strict accordance with the instructions.
1. After the sand making machine is installed, it is necessary to idle load to test the stability of the sand making machine. Firstly, check the flywheel, bearing and fastening bolt parts, observe whether there is abnormal sound inside the sand making machine, and stop it in time if there is any abnormality;
2. The production line equipment of the sand maker must be started in sequence. When the sand maker is started, observe the current situation. When the sand maker is started, the current will rise sharply. This is an instantaneous current, which is a normal phenomenon. However, if the current remains high for a long time, stop the machine immediately and check the sand maker and circuit.
3. Wear-resistant parts may appear during the use of sand making machine, so it is necessary to check the wear degree of wear-resistant parts regularly. If the wear degree is too large, it should be replaced in time. In the production process of sand making machine, materials larger than the feed size of sand making machine should be prohibited from entering, and the feed should be continuous and uniform to obtain good production benefits;
4. When the sand maker is in use, it is necessary to arrange a special person to be responsible for maintenance, and turn off the power supply of the sand maker during maintenance to ensure the safety of the maintenance process.
The technical principle and operation precautions of machine-made sand equipment are introduced above. If the above answers are useful to you, please encourage me to praise me so that I can help more people. Thank you!
