What are the process technology essentials of 110 cone double extruder


I think for a lot of my friends,110 cone doubleExtruders are also well known mechanical devices. Many chemical enterprises need to use this kind of mechanical equipment, and considering its excellent working performance and efficient production efficiency, it has been favored by many enterprises, so what are the process technology essentials of 110 cone double extruder together!

Technical Points of 1. 110 Cone Twin Extruder

  1、110 cone doubleExtruder extrusion process, the material from the glassy state to the molten state of the process, in addition to the plasticized material required heat and feed heat to achieve a stable balance, so that the material to achieve the ideal plasticization, the melt pressure is also a very important control indicators. Because the material in the extrusion process by the mold resistance, screw compression ratio at all levels, its itself is not the existence of atmospheric pressure, not the same die, screw compression ratio at all levels of basic balance and stability, not variable.

2. Under the premise of a certain extrusion speed, when the feed speed increases or decreases, the material capacity of the exhaust section remains unchanged due to the change of the material capacity of the feed screw. With the change of the compression ratio, the penetration pressure of the feed section and the compression section also increases and decreases. Under the premise of a constant feed speed, increasing or decreasing the extrusion speed will also change the material capacity of the feed screw.

Since the material capacity of the exhaust stage remains unchanged, the supply stage and the compression stage change with the compression ratio, and their penetration pressure also rises or falls. The feed speed increases or decreases simultaneously with the extrusion speed, but the screw material capacity of the feed section remains unchanged, only the melt pressure changes caused by the increase or decrease of the speed.

Analysis of Problems Existing in 110 Cone Twin Extruder

1. The meat grinder is severely worn

If the gap between the reamer frame and the inner wall of the mud tank is too large or the spiral angle of the reamer blade is wrong, the reamer frame should be replaced with attention to the gap of 3-5mm(mm ), and the reamer blade should be made according to the design angle.

2, the surface is too rough

The surface of the meat grinder blade is rough, and the friction between the mud and the blade is too large. The surfacing meat grinder should avoid group surfacing, replace it all at one time, and replace it in sections in order to ensure the smooth completion of the bricks.

3. The mud cylinder wall lining is seriously worn

The gap between the blade of the meat grinder and the wall of the mud tank is too large, and the mud rotates excessively in the mud tank. At this time, the new mud cylinder bushing should be replaced, or several parallel or axially inclined ribs should be installed on the inner wall of the bushing to stop the invalid rotation of the mud to replace the grinding groove and increase the effective extrusion.

4. The gap is too large

The gap between the mud press and the meat grinder is too large to scrape mud. At this time, it is necessary to adjust or repair welding, update, so that the gap between the knife plate and the reamer blade is less than 10mm (mm).
