Ways to increase the output of Bentonite Mills

       

 In the cement production process, the Bentonite Mill is one of the key equipment for the preparation of cement. The Bentonite Mill consumes about 60%-70% of the total power consumption of the cement. The quality of the raw mill determines and affects the technical parameters of the cement rotary kiln, but if the Bentonite Mill configuration is reasonable, it can make up for some defects of the cement clinker. Therefore, improving the output of Bentonite Mills is of great practical significance for cement enterprises to achieve high quality, high yield and low consumption.

        
        

1, reduce the size of the grinding material

        
        

In recent years, the grain size of cement has been paid more attention by cement companies, and the industry’s view of “breaking more and less grinding” has gradually been accepted. The so-called “more breaks and less grinding” is to change the particle size of the 30mm material that was originally entered into the Bentonite Mill to 3mm or less, thereby increasing the mill output. The cement enterprise adopts the Bentonite Mill + roller press combined with grinding, which can reduce the grinding grain size to less than 2mm and increase the output by more than 50%.

        
       

 2. Optimize the cement grinding process

        
       

 At present, the production of cement mostly uses an open circuit system, the fineness of the cement is not easy to control, and the fluctuation is large. If the open circuit system is changed to a closed circuit system, a high-efficiency rotor classifier and bag filter are added, which has a good effect of increasing the specific surface area of ​​the cement and increasing the strength of the cement.

        
        

3, control the moisture and temperature of the material

        
        

Controlling the integrated moisture of the milled material at 1,5% is the basic premise for ensuring the high quality and high yield of the Bentonite Mill. Therefore, the cement enterprise needs to strictly control the moisture content of the mixed materials and the drying moisture in the material production process, and the temperature of the material to be milled is controlled within the process requirements to ensure the good operation of the Bentonite Mill.

        
       

 4. Control the wearability of the milled material

        
       

 The clinker and slag can be separately ground, and the appropriate amount of ore powder can be separately prepared during the shutdown of the winter cement. In the process of producing cement, it can be directly added, thereby improving the grindability of the slag; The fly ash which is close to the fineness of the cement is used as a mixed material to improve the wearability of the mixed material. In short, in order to increase the output of Bentonite Mills, it is necessary to optimize the structure of cement raw materials and improve the wearability of the materials to be ground.

        
       

 5, to ensure smooth ventilation inside the Bentonite Mill

        
       

 In daily production, cement companies should fully recognize the importance of ventilation in the mill, and at the same time, do a good job of airtight containment. In addition, measures such as strong ventilation and bag filter can be used to ensure smooth ventilation in the Bentonite Mill.

        
        

6, timely adjustment of the grinding body grading

        
       

 According to the actual production needs, if the equipment configuration allows, the proper addition of the ball and the section load will greatly help to improve the output of the Bentonite Mill. In addition, due to the harsh working environment of the Bentonite Mill of the Bentonite Mill, it is often in direct contact with various cement raw materials, and the wear is also quite serious. Therefore, attention should be paid to the damage of the abrasive body.

        
        

7, control the fineness of the finished product

        
        

It is well known that the control index of cement fineness has a great influence on the performance of cement. Cement enterprises can control the fineness of cement by sieve analysis method. The 0,08mm sieve residue is controlled at 1,8%-2,8%.
