Industrial waste slag treatment equipment – Great Wall Machinery Co., Ltd

01 waste slag treatment – the trend of the times

According to the statistics, during the recent ten years, the cement industries of the world cement powers like German and Switzerland show the truth that: cement strength is increasing, and clinker consumption is declining. In future, these cement powers will replace traditional Portland cement with type II cement which mix large amount of slag and small amount of clinker.

Great Wall Machinery, the first vertical mill grinding integrated system, can steel slag, slag, nickel slag, manganese residue and other waste residue for processing, has been in the world to build more than 100 residue production line.

 

02 Introduction for advanced industrial waste slag grinding process

 

 

 

 

Slag production processes

Advanced grinding equipment

  1. Integrate the functions of crushing, drying, grinding, separating and conveying. It occupies small area and can be arranged outdoors, that makes investment costs decrease.
  2. It is equipped with PLC/DCS auto control system to realize the remote control.
  3. Fineness of finished product can be regulated with 400~550㎡/kg to meet various requirements.
  4. It has a low power consumption not more than 42Kwh/t.
  5. Equipment system is in the negative pressure state, with low noise, non-dust leakage, keeping the surroundings clean.
  6. Equipment system operates stably.
  7. Original spare parts reduce your worries.
  8. Metal recovery benefits from slag is high.
Advanced technology
Introduce German Loesche vertical mill technology to optimize the working mechanism of grinding roller and grinding table.
A number of vertical mill technologies obtain the certificate of utility model issued by the State Intellectual Property Office.
The whole system operates stably with low electric power consumption not more than 20%.
 
Short delivery time
Possess the ability of large-scaled machining and casting, and ensure the construction period can be shortened to 6-8 months giving priority to the quality.
