The dross is byproduct derived from refine in the process of melting and casting aluminum. In the process of casting aluminum ingot and finished product, user must clear dross from the furnace. When user clear dross and dross contact with air, aluminum metal will be oxygenized and contributed to alumina powder because dross contain a great deal of aluminum content . This phenomenon contributed to aluminum metal loss and environmental pollution. So, dross process is an important procedure of aluminum casting. We produce pressure scrap type and stirring type aluminum ash processor according to the situation of aluminum plant, not only environmentally friendly, high degree of automation, labor saving, low energy consumption, but also greatly reduce the burning loss of aluminum liquid, and greatly improve the rate of aluminum recycle. Hot-stir squeeze type aluminum ash processor separate maximun the aluminum metal in aluminum slag using the principles of heat separation in a short period of time to reduce burning demage and better recycle metal,collocate high-temperature dust catcher and pulse bags to remove ash to remove ash to achieve environmental protection standards.
