[0002] Some industrial waste residues are alkaline, such as steel slag and carbide slag. They can neutralize excess alkaline substances in saline-alkali land, lower the soil pH, and reduce the harmful effects of salinity on plants. Meanwhile, fly ash particles are fine and porous, increasing soil aeration and making the soil looser, which is beneficial for plant root growth and respiration. Therefore, using industrial waste residues as a soil conditioner for saline-alkali land has a certain effect on environmental remediation.

This wear reduces mixing efficiency and can even lead to blade breakage, disrupting normal operation and necessitating frequent replacements of the mixing shaft and blades. Current blade replacement procedures typically involve using wrenches or other tools to loosen the bolts connecting the blades to the shaft, removing the old blades, and then securing them with new bolts. This process is cumbersome, reduces the efficiency of the mixing device, and the blades' location inside the mixing tank makes cleaning difficult.
