Improvement of production process
1) Improve 2 procedures
① Improve mixing. Before the improvement, the SI14 type 0.4t mixer mill of Henan Luohe Manufacturing Plant was used. After the improvement, the SND1600 1t wet mill of Liaoning Huludao Manufacturing Plant was used. Increased labor productivity.
② Improve the mixture conveying. Before the improvement, the mixture was unloaded from the mixer to the ground after mixing, and then manually shoveled from the ground to the belt conveyor. After the improvement, after the mixture is mixed, it is directly discharged from the mixer to the belt conveyor through the unloader, which greatly reduces the labor intensity of the workers and improves the production efficiency.
2) Add 4 processes
① Increase the hopper. Before the improvement, each bag of 25kg of lightly burned magnesium powder and magnesia was manually transferred to a 1.5m-high feeding platform. After the improvement, the bag was manually opened directly into the hopper with an elevation of 0.00, which reduced the labor intensity of the workers and improved the labor efficiency.
② Increase the loading belt conveyor. Before the improvement, the bag was manually opened 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 and controlled. At the same time, iron removal devices are added to prevent iron compactors and other equipment from damaging the compactor and ball press, which improves the safety of the production line and the stability of the feed.
③ increase the compaction process. Before the improvement, there was only the ball pressing process, and the product was extruded only once, and its size was 40mm × 40mm × 35mm. After the improvement, an I compactor was added, and the product was subjected to secondary extrusion. The size of the first extruded product is 30mm × 30mm × 25mm, and the size of the second extruded product is 40mm × 40mm × 35mm.
Increasing the compaction process is the key to the transformation of the entire light-burned magnesium ball production line. The product undergoes two extrusions. The first extrusion makes the magnesium sphere crystals close to each other under the effect of external force, shortening the distance r between the magnesium sphere crystals, and the second extrusion makes the magnesium sphere crystals rely on the external force. Closer, the distance r between the magnesium sphere crystals is smaller. As r is smaller, the positive and negative electrons around the magnesium powder crystals inside the magnesium sphere are easier to pair, the attractive force between the electrons increases, the ionic bond increases, and the intermolecular force increases. Therefore, r
④ Control the amount of water added. Controlling the moisture content of the pellets is another key to ensuring the strength of the magnesium pellets. The amount of water directly affects the internal structural strength of the magnesium balls. Less water makes it difficult to form intermolecular forces between ions, ionic bonds, and magnesium sphere crystals
