Si Mn alloy is also known as silicomanganese slag smelting slag, a solid waste generated during smelting manganese alloys, due to the limitation by the smelting process, these silicomanganese slag contains a certain amount of manganese alloys, metallurgical slag processing these silicomanganese The recovery of silicon-manganese alloy can obtain more objective economic benefits, and has the advantages of small investment and low risk. Therefore, the processing project of silico-manganese alloy smelting slag has been regarded by many small and medium-sized investors in recent years. The process flow of a silicon-manganese alloy smelting slag is described below and is for reference only.

Treatment process and ferrochromium alloy smelting slag manganese alloys metallurgical slag treatment process substantially similar, but there are some differences. The ferrochrome alloy smelting slag has coarse ferrochrome alloy particles, while the silico-manganese alloy in the smelting smelting slag is generally unevenly embedded with fine particles. Therefore, in the treatment process, the ferrochrome smelting slag treatment process is as coarse as possible. Granular ferrochrome alloy, while recovering fine-grained ferrochrome alloy, and since there is basically no coarse-grained silico-manganese alloy particles in the silico-manganese slag, it can be directly broken into fine particles, and then all the fine-grained silicon-manganese alloys are sequentially selected and recovered. The specific recycling methods and equipment are mainly re-election, and the re-election method can obtain energy-saving, high-efficiency, environmental protection and other mineral processing effects, and the selection effect is also very ideal, and does not cause secondary harm to the environment. The re-election equipment used is mainly a jig, and sometimes a shaker is also used.

The following is a flow chart of the treatment process of silicomanganese smelting slag:

Due to the high hardness of the silicon-manganese alloy slag, the process adopts a two-stage crushing process, and both are jaw crushers , which can effectively reduce the wear of the crusher, thereby reducing the cost of the silicon-manganese smelting slag treatment. According to the investigation of many years, the JM1070/2 sawtooth waveform jig is mostly used in the selection of the jig. The jigging waveform of the normal working of the machine is sawtooth waveform, which is fine-grained. The recovery of heavy minerals is excellent, and there are fine-grained silicon-manganese alloy particles in the silico-manganese slag. Therefore, it is an ideal choice to treat silico-manganese slag with a sawtooth jig.

ECU Environmental Control Unit

ECU Environment Control Unit is portable cooling air conditioner unit special design for military camps, relief camps,medical camps, working camps. Portable ECU offer all-in-one services for air conditioning, area cooling, dehumidifying, and portable heating needs. Environment control unit completely self-contained and portable, portable ECU have 36000BTU and 60000BTU two models for your choice. The ECU control system is by contactor only, it's much more reliable design for military camps use. ECU can supply cooling at max 55 ℃, and supply heating at max -45℃ environment. The environment control unit most important advantage is can be stack on each other, so can save the space on transport and storage.
