Small internal mixer is a kind of mixing equipment with high strength and clearance developed on the basis of open mixer, which is mainly used for rubber molding and mixing. Small internal mixer not only has a large mixing capacity, but also has a very high production efficiency, which can overcome the problem of dust flying everywhere, effectively reduce unnecessary loss of admixture, the main of small internal mixer To do this
1. At the same time of calculating the amount of primary refining and the actual formula, the reasonable arrangement should be made according to the capacity of the mixing chamber and the appropriate filling coefficient
2. After the actual formula is determined, accurately weigh the amount of various raw materials in the formula, place the raw rubber, small materials, accelerants, etc. separately, and then arrange them on the shelf in order
3. Turn on the power supply, switch, etc. of the internal mixer, preheat the internal mixer first, check whether some other air pressure, water pressure, voltage, etc. meet the standards, and whether the temperature measurement system, timing device, power system indication and record are in normal state, etc
4. After the mixer is preheated, first stabilize it for a period of time, then prepare for mixing, finally lift the top bolt, and then put the cut small pieces of raw rubber into the mixer from the feeding port. The mixing time is set as one minute
