Chaeng environmental friendly lime kiln

Recently, the number of advisory customers for Great Wall Machinery lime kiln is increasing especially gains more attention from many building materials factories, after put into production of annual output of 400,000 tons lime production line, which is Great Wall contract to build for Guangxi Huayan.

It is reported, at present, there are a lot of lime production line were built in domestic, their common features are output in 200-300 tons per day, running in good condition in the later, ideal for build in small and medium lime enterprises, for example, Guangxi Huayan with capacity of 300 tons per day .

Unlike domestic, the new lime kiln capacity is higher at abroad, 2200 tons per day has been put into production, which will be the development tendency of domestic lime kiln. That is to say, develop to upsizing, towards large-scale direction.

1、How about the lime activity degrees produced by the environmental lime kiln?

The lime activity degrees produce by environmental lime kiln is higher than the shaft kiln. The lime activity can reach up to 400ml on equal terms.

2、How about products produced by the environmental kiln?

3、What’s the requirement on the granularity of raw material for lime kiln?

Rotary kiln can be directly calcine fine limestone in 10-50 mm. Build lime production line with rotary kiln, not only can make full use of high-quality limestone resources, and in line with the lime industry sustainable development policy.

4、Does lime production line need configure the preheater?

Vertical preheater configured in the kiln end can make full use of high temperature flue gas produced by calcination in rotary kiln; preheat limestone from room temperature to the initial state of decomposition, which not only can greatly improve the production of rotary kiln, can reduce heat consumption per unit product adequately.

5、How to do the environmental friendly?

The smoke temperature exhaust from vertical preheater of kiln end is low, between 280-350 ℃; low dust content, about 20g/Nm3, efficiently simplify the configuration of follow-up treatment to the flue gas, can successfully meet environmental requirements.

6、How much money to invest environmental lime kiln?

Because of different production capacity and the specific mining conditions of each region, the entire line and single devices with different prices, so please contact us for the details.

7、What is the production process of lime line?

Lime production line is a complete production line that composed of vertical preheater, rotary kiln, grate cooler, flue gas treatment system, raw material conveyor systems, product delivery systems, coal grinding system.

All line adopts advanced technology, DCS central control system in reliable performance, centralized operation and management in the main control room.

Chaeng Energy saving cement vertical grinding mill

Now, most cement factory in China still take the high energy emission and high pollution cement ball mills.But the vertical roller mill has take the materials bed grinding, and take the crushing, grinding,drying and selection together. During grinding, it not only reduce the electric emission, but also reduce the Co2 emission. For many companies, take the vertical roller mills to replace the ball mills is the best choice. The age of grinding without balls is coming. 
1. Vertical roller mill system saving energy can over 30%.        
From our customers, compared with ball mills, the vertical roller mill has big advantages of unit electric emission, grinding balls loss and the total equipment. 
Take our GRMK46.41 vertical roller mill as an example, the details loss parameters as the form below:

Items	φ4.2×13m ball mill and roller press machine	GRMK46.41 vertical roller mill
Design capacity(t/h)	140	150
Reality capacity(t/h)	150	180
Fineness(m²/kg)	370	370
Electricity emission(kWh/t)	49	33
Grinding balls loss(g/t)	25	5
Total power(kWh)	7000	5000

From the form above, the electric emission of vertical roller mill is 33kwh/t, compared with ball mill, lower 16kwh/t，the lower ratio is 33%. At the same time, the capacity will raise 30% and the cost lower 80%.

2. The vertical roller mill system can reduce the Co2 emission.

With the obviously low energy cost, high efficiency advantages,according to the texts, compared with ball mills, during per ton cement production, the vertical roller mill can reduce the Co2 emission 7.9-19 kg. It means that, a 5000t/d cement plant, it can reduce the Co2 emission 1185o--28500 tons per year.

How to control the quality of steel casting Nodes ?

Thesteel casting Nodes is the hinge of force transferring in the design of steel structure and play an important role in the whole steel structure. It is the intermediate switch station for transferring the floor load and roof load to pillars. We can understand simply that ,if it appears quality problems of steel casting nodes in anti-seismic progress , the whole floor would collapse.Thus it is very important.

As domestically well-known large steel casting factory, Chaeng  Steel Casting has provided large steel nodes processing service for many domestic airport, stadium and high-speed rail station (HSR). It is considered as the supplier with first-class quality and first-class service by numerous customers. The person in charge of it tells How to get the high-quality steel casting nodes. on one side, it comes from the years of exploration for steel nodes casting technology.on the other side , it depends on the over-all testing for nodes quality by advanced testing equipment

Testing for chemical components

The steel nodes of steel structure have higher requirements for chemical components than other fields. It restricts the contents of C, S and P. So it needs to test molten steel . Chaeng Steel Casting adopts spectrum analyzer to test the chemical components of steel nodes and it can analyze the chemical elements of casting steel materials visually and directly.It ensures that the selected materials conform to the standard.

Mechanical Property inspection

Chaeng Steel Casting test the mechanical property by the standard specimen made by the same furnace molten steel of steel casting , and provide the test report for mechanical property

Non-destructive defection inspection

We own advanced ultrasonic , magnetic defection equipment,which can do 360 non-destructive defection inspection for steel castings internally and externally.it can effectively guarantee the quality of steel nodes. We have achieved the secondary level for the key parts inspecting.

Other inspection

To avoid the quality problems, we do surface roughness inspection and beveling inspection for steel nodes.

If there are needs for large steel casting nodes and other casting parts recently, please call our HOTLINE +86-371-55019608 and welcome to consulting.

For large steel casting nodes , Chaeng is your best choice.
