Chrome iron slag treatment process Description:
The ferrochrome slag treatment process in a gravity separation method for recovering from ferrochromium slag chromite alloys, the use of two sorting jig, respectively ferrochrome coarse and fine particles, so that the recovery benefit ferrochrome maximize.
First, the large chromite ore slag is broken into small pieces by a coarse jaw crusher , and the small piece of chromite ore slag enters the fine jaw crusher for fine breaking, so that the final particle size is controlled within 30 mm, and then enters the silo, below the silo. Electromagnetic vibrating feeder is set, and the crushed ferrochrome slag is evenly fed into the AM30 jig for coarse jigging sorting to obtain coarse ferrochrome and tailings. The tailings are embedded with fine chrome For ferroalloys, the AM30 jig tailings should be ground by a rod mill to obtain sand-like chromite ore slag. The LTA1010/2 jig is subjected to secondary jigging to obtain fine-grained ferrochrome and waste.
The process has a total recovery rate of more than 90% for ferrochrome alloy, and is a process for recycling and recycling ferrochrome slag widely used in China.
List of ferrochrome treatment equipment configuration:
| name | model | Power (KW) | amount) |
| Crude jaw crusher | PE400*600 | 30 | 1 |
| Fine jaw crusher | PEF250*1000 | 37 | 1 |
| Jig | AM30 | 3 | 1 |
| LTA1010/2 | 3 | 1 | |
| Rod mill | Φ1200*4500 | 55 | 1 |
| Conveyor | Model 600 | 5.5 | —— |
| feeding machine | GZ3 | 0.35 | 1 |
| Silo | 20m3 | —— | 1 |
After the ferrochrome alloy has been recovered, the ferrochrome content in the ferrochrome is extremely low, and it is in the form of fine granules. It can be sold again to cement plants, new building materials factories and other enterprises to make new building materials. The whole process has realized the solid waste of chrome iron slag. The entire recycling, not only reduces the waste of useful resources, but also reduces the occupation of land by solid waste residue, the harm to the environment and human health.
I plant has a wealth of experience and unique insights disposal and recycling slag ferrochrome, ferronickel slag, stainless steel slag, slag silicon manganese and other metals smelting slag, welcome customers and friends to visit our factory to discuss.
1. The machine is to put the processed meat and fish into vacuum barrel to knead, massage, and roll.
2. It can improve the speed for meat to absorb salt and seasoning, and keep the meat moisture maximum.
3. This machine can exhaust air from meat through vacuum, so as to not have thermal expansion at subsequent heat process for the meat.
4. It can also improve the appearance color, elasticity, and tenderness of salted meats.
5. This whole machine adopts stainless steel materials, with high quality and reach health standard. Necessary equipment in the meat product factory.
