Henan Meng Electric 1 Million+600,000 t/a slag powder production line

Raw material: slag

Capacity: 1 million +60t/a

Main equipment: GRMS53.41slag vertical mill, GRMS46.41 slag vertical mill

Project in: Mengdian,Henan

Project background

Slag micropowder is a kind of concrete admixture with superior performance. It can be used to replace a large amount of clinker in cement and a large amount of cement in concrete. It can also improve the comprehensive performance of concrete and reduce the production cost and energy saving of enterprises.
Henan Mengdian Group Cement Co., Ltd. is a well-known large cement company in China. For many years, it has been one of the top 30 cement clinker production enterprises in China. In order to extend the industrial chain and meet its own production needs, in 2012, Henan Mengdian chose chaeng as the main contractor, and built a production line with an annual output of 1 million tons of slag powder / 1.5 million tons of cement for the main contractor, using chaeng GRMS53 .41 Slag vertical mill, energy saving and environmental protection, small area.
In this project, chaeng adopted some new processes, for example, using a combination of buried scraper + elevator + pipeline iron remover to transport the vertical mill slag to keep the material in the closed shell, and then equipped with a dust collector to provide Negative pressure can avoid the overflow of dust and make the whole line more environmentally friendly; adopting dry and wet separation technology to effectively solve the blocking phenomenon of spiral reamer plate; vertical mill return material (external circulation) and wet slag are separated into the grinding and slag are entered The flow stabilization bin is set before the mill, and two gate valves are used to replace the three-way feed valve with a high failure rate, etc., so that the production line runs more smoothly and reliably.
In 2016, in order to meet the development needs, Henan Mengdian Group decided to expand the slag powder production line. The 1 million tons of slag powder production line constructed by chaeng for it has been running well since it was put into production in 2012 and has won recognition and trust from customers. As a result, Henan Mengdian Group once again joined hands with chaeng to start cooperation on a 600,000-ton annual slag powder production line project.
The production of 600,000 tons of slag powder production line has three highlights:

Highlight 1: Environmental protection
1. The heat source of the project adopts the dual-use method of gas, which is more environmentally friendly;
2. The project's slag shed adopts a closed design, which can reduce dust pollution.

Highlight 2: The feeding system is equipped with spiral reamer
The main machine of the project adopts chaeng GRMS46.41 slag vertical mill. The vertical mill feed system uses a screw reamer, which can break up the sticky materials with large water content and improve the input output and grinding efficiency.

Highlight 3: Fan and powder separator can be adjusted by frequency conversion
In the 600,000-tonne ore powder production line, the fan and powder separator can be adjusted by frequency conversion, which can not only adjust the fineness of the finished product to meet the different needs of customers, but also reduce energy consumption and save more energy.

Operating situation

The project's annual output of 1 million tons of slag powder production line was implemented in August 2012, and qualified ore powder was produced on the day of implementation. The finished product's specific surface area has reached 420 (m² / kg) after inspection, which is higher than the national standard . Since it was put into production, the production line has been running smoothly. The electricity consumption per ton of ore powder (average) is controlled below 35 degrees. The coal consumption per ton of ore powder is about 17, 18 (kg), and the energy consumption is low.

The project's annual output of 600,000 tons of slag powder production line was put into operation in November 2017. The entire production line is running smoothly and meeting the production standard.

Customer reviews
The project's output and energy consumption indicators are at the domestic advanced level, which has won high praise from customers. The customer said, "The service of chaeng is very thoughtful, we are very worry-free, the whole line is well designed, and the energy consumption is low, which has met our expectations.
