Introduction:
In the cotton industry, a Truetzschler Multimixer is used to simplify the process of blowing cotton fibers. Before spinning cotton fibers into yarn or using them for other purposes, cotton fibers must be separated and cleaned before they can be blown. As natural fibers vary in quality, the Truetzschler multimixer is used to blend raw materials of different quality to even out and equalize the quality of delivered material. A six- to twelve-chambered system is employed in this zone. The inlet is located at the upper side of the system to ensure that the tufts are evenly distributed throughout the system. In the system, the outlet for transporting air is located at the bottom. With the outlet technology, material is taken up from each chamber evenly by rotating rollers and delivered after mixing by rotating rollers. As a result, mixing takes place homogeneously at both inflow and outflow. Truetzschler multimixer is used after Automatic Bale Opener in the Truetzschler blow room line.
Working Principle of Truetzschler Multimixer:
In the multimixer machine, there are six to twelve hoppers. The cotton bales are opened and premixed by an automatic bale opener. As we know, the feed duct is located above the hopper, which is where the blended cotton is blown into the feed duct. At first, the multimixer starts feeding cotton fibers to the first hopper which is at the end of the feed duct. The feed duct is filled only just below the photocell located in the adjacent hopper. When the hopper just below the photo cell is filled, the closing flap is closed. By pushing a push button, the second hopper’s closing flap is opened. Now the second hopper is filled with cotton. It is filled to a higher level than the first hopper with cotton. The closing flap of the second hopper is closed when the cotton level is higher than the first hopper. The closing flap of the third hopper is now open. The third hopper is now filling with cotton fibers. Whenever the cotton fiber level is higher than the second hopper, the closing flap of the third hopper is closed, while the closing flap of the fourth hopper is opened. The closing flap of the first hopper is opened when the last hopper is filled with cotton and the level is higher than the previous hopper.
With the help of two deliver rollers, the bottom of each hopper is closed, transferring the material to the opening roller in a gradual and uniform manner. As the delivery rollers of the entire hopper are controlled by two variable speed motors with a range of 1 : 6, the output of the multimixer can be adjusted to match the feed requirements for the next machine. After the opening roller loosens the material into tufts, it is sucked by the subsequent condenser into the blending channel.
Conclusion:
In the cotton industry, the Truetzschler Multimixer is used to mix and clean cotton fibers efficiently. Its ability to handle large volumes of cotton and to produce uniform results makes it a valuable tool for improving cotton quality and productivity. This machine is helped to mixing the cotton fiber homogeneously. some low quality cotton fiber is mixed with high quality cotton fiber. finally, we get average quality yarn. that’s why we can say, Truetzschler multimixer is also help to reduce the production cost. However, please feel free to ask me any question about this article.
