1) Construction of 2100m2 buildings; 2) Casting 3500m2 concrete floor; 3) Purchase one ZLM 30-3 loader. Light burned magnesium ball
Improvement of production process
1) Improve 2 processes
① Improve mixing and grinding. Before the improvement, the SI14 type 0.4t mixer from Henan Luohe Manufacturing Factory was used. After the improvement, the SND1600 type 1t wet roller from Liaoning Huludao Manufacturing Factory was used, which improved the mixing effect and shortened the mixing time as well as the labor productivity.
② Improve mixture conveying. Before improvement, after mixing, the mixture was unloaded from the mixer to the ground, and then manually shoveled from the ground to the belt conveyor. After improvement, the mixture is directly discharged from the mixer to the belt conveyor through the unloader after mixing, which greatly reduces the labor intensity of workers and improves the production efficiency.
2) Add 4 processes
① Add hopper. Before improvement, each bag of 25kg shall be manually Light burned magnesium powder And magnesia to a 1.5m high feeding platform. After the improvement, the bag was opened manually and put into the feeding hopper with an elevation of 0.00, which reduced the labor intensity of workers and improved the labor efficiency.
② Add feeding belt conveyor. Before improvement, the bags were opened manually on the feeding platform and put into the mixer. After the improvement, the raw materials of the feeding hopper directly enter the feeding belt conveyor, and the feeding amount is balanced. At the same time, an iron removal device is added to prevent ironware from damaging the compactor and ball press, improving the safety of the production line and the stability of the feeding.
③ Add compaction process. Before the improvement, there was only ball pressing process, and the product was only extruded once, with a size of 40mm × 40mm × 35mm。 After the improvement, I set of compactor is added, and the product needs to undergo secondary extrusion. The size of the first extruded product is 30mm × 30mm × 25mm, the second extrusion product size is 40mm × 40mm × 35mm。
Adding compaction process is the key to the transformation of the whole light burned magnesium ball production line. The product has been squeezed twice. The first extrusion makes the magnesium sphere crystals close to each other under the external force, shortening the distance r between the magnesium sphere crystals. The second extrusion makes the magnesium sphere crystals closer under the external force, and the distance r between the magnesium sphere crystals is smaller. As r is smaller, the positive and negative electrons around the magnesium powder crystal inside the magnesium sphere are easy to pair, the attraction between electrons is increased, the ionic bond is increased, and the intermolecular force is increased. Therefore, r
④ Control the amount of water added. Controlling the moisture content in pelletizing is another key to ensure the strength of magnesium spheres. The amount of water directly affects the internal structural strength of magnesium spheres. With less water, it is difficult to form intermolecular forces between ions, ionic bonds and magnesium spherical crystals
