Method for improving production process of light burnt magnesium ball

1) Construction of 2100m2 buildings; 2) Casting of 3500m2 concrete floor; 3) Purchase of one ZLM 30-3 loader. Light burnt magnesium powder

Improvement of production process

1) Improve 2 processes

1 Improve the mixing. Before the improvement, the SI14 type 0.4t mixer mill of Henan Luohe Manufacturing Plant was adopted. After the improvement, the SND1600 type 1t wet mill of Liaoning Huludao Manufacturing Plant was adopted to improve the mixing effect and shorten the mixing time. Increased labor productivity.

2 Improve the mixing of the material. Before the improvement, the mixture was mixed and discharged from the mixer to the ground, and then manually pulled from the ground to the belt conveyor. After the improvement, the mixture is directly discharged from the mixer through the unloader to the belt conveyor, which greatly reduces the labor intensity of the worker and improves the production efficiency.

2) Add 4 steps

1 Increase the hopper. Before the improvement, 25kg of light burnt magnesium powder and magnesia per bag were manually transferred to a 1.5m high feeding platform. After the improvement, the bag is directly opened by putting the bag into the hopper with an elevation of 0.00, which reduces the labor intensity of the worker and improves the labor efficiency.

2 Increase the loading belt conveyor. Prior to the improvement, the bag was manually opened on the loading platform and placed in the mixer. After the improvement, the raw materials of the hopper directly enter the feeding belt conveyor, and the feeding amount is balancedly controlled. At the same time, the iron removal device is added to prevent the iron and the like from damaging the compactor and the ball press, thereby improving the safety of the production line and the stability of the supply.

3 increase the compaction process. Before the improvement, only the ball pressing process, the product was only extruded once, and its size was 40mm × 40mm × 35mm. After the improvement, a press machine was added, and the product was subjected to secondary extrusion. The size of the first extruded product was 30 mm × 30 mm × 25 mm, and the size of the second extruded product was 40 mm × 40 mm × 35 mm.

Increasing the compaction process is the key to the transformation of the entire light burnt magnesium ball production line. After two extrusions, the first extrusion causes the magnesium ball crystals to approach each other under the action of external force, shortening the distance r between the magnesium ball crystals, and the second extrusion causes the magnesium ball crystals to act under the external force. To be closer, the distance r between the magnesium ball crystals is smaller. The smaller the r is, the positive and negative electrons around the magnesium powder crystal in the magnesium ball are easily paired, the attraction between the electrons increases, the ionic bond increases, and the intermolecular force increases. Therefore, r

4 control the amount of water added. Controlling ball moisture is another key to ensuring the strength of the magnesium ball. The amount of moisture directly affects the internal structural strength of the magnesium ball. Less water, the intermolecular forces between ions, ionic bonds and magnesium sphere crystals are difficult to form
