Roots blower manufacturer Example of Roots blower for aquaculture [Purchase Tel.: 0531-83663588]
With the continuous extension and development of the application field of Roots blower, it is now widely used in bulk cargo transportation, sewage treatment aeration, steel production, etc. Roots blower also plays an extremely important role in cement plants. In 2019, the person in charge of procurement of Roots blower of Anhui Cement Plant came to the company to investigate and purchase Roots blower on the spot, and clearly required to reduce the electricity charge. According to statistics in recent years, the rise of electricity charge price further increased the proportion of electricity charge in the cost of the cement plant. As a major power consumer, it is extremely urgent for cement plants to reduce their electricity bills.
Therefore, many shaft kiln cement plants have selected frequency converters for technical transformation of shaft kiln, especially Roots blower, and have achieved very significant economic results. It has changed the traditional production mode of adjusting the air pressure or air volume by adjusting the opening of the outlet (inlet) valve. The labor intensity is reduced, the timeliness of adjustment is good, the product qualification rate is improved, and the unit energy consumption is significantly reduced.
This time, the person in charge of the project department purchased six three blade roots blowers. See the following table for specific data
| Pressure: 10kpa Flow: 13m3/min | Purchase quantity | Total purchase quantity |
| Roots blower in series | 4 sets | 6 sets (please consult our technicians for detailed models) |
| spare Three blade roots blower | 2 sets | 6 sets (please consult our technicians for detailed models) |
The following figure shows the application of Roots blower in cement plant
Roots blower is an important mechanical equipment used for calcination and material transportation in the production line of neutral kiln and rotary kiln in the cement industry.
1. Air supply for shaft kiln calcination
The use of shaft kiln to burn cement has the characteristics of low energy consumption, less start-up capital and high efficiency. Roots blower is widely used in air supply of calcined cement because of its structural characteristics, good exhaust and good pressure adaptability. For vertical cement kiln, due to the change of the height of the material layer in the kiln, the required air pressure often changes. If the material layer in the kiln is higher, the required air pressure is higher, and the required air volume is larger. The hard exhaust characteristics of Roots blower can better meet this requirement.
2. Raw material conveying homogenization of rotary kiln
Rotary kiln is used to produce cement. Roots blower is used to transport and homogenize raw meal. The production is floated to homogenize raw meal. For such fans, the pressure rise is high, generally 58.8kpa or more; Flow 5~160m/ min。
3. Model selection parameter table
Select the appropriate model according to the required air volume and air pressure. The following figure shows the wind pressure flow diagram of roots blower. Different types of roots blower can be selected according to different needs.
Air pressure: the air pressure entering the kiln is used to overcome the resistance in the kiln, and the air pressure should be large if the resistance in the kiln is large.
Blower type:
The types of fans commonly used in mechanized shaft kiln are Roots fan, Yeh's fan and centrifugal fan.
Formation principle of mechanical shaft kiln clinker Movement of materials and air flow in mechanical shaft kiln Movement of materials in mechanical shaft kiln
The kiln body of mechanical shaft kiln is fixed, and the feeding balls are from top to bottom.
Cause of movement: It is caused by the discharge of clinker and the volume shrinkage of pellets during the calcination process. Because the mechanized shaft kiln does not rotate, the materials in the shaft kiln do not roll except for vertical movement from top to bottom, and the materials are rarely mixed with each other, which is one of the reasons for the uneven quality of clinker in the shaft kiln.
