How many kilograms of materials are suitable for mixing in the mixing bucket of the PVC mixer depends on the specific gravity and density of the materials, powder and powder mixing, powder and particle mixing, and powder and additives mixing. According to the 1:1 specific gravity of the materials, the mixed materials normally account for 75% of the total volume.
At this time, the friction generated during mixing heats up quickly, reaching the set temperature of the materials (110 ℃), which generally takes 8-10 minutes; When the material accounts for about 50% of the total volume or less, it takes longer to reach the preset temperature; When the material content in the barrel of the PVC mixer exceeds 75%, the mixing efficiency is reduced due to insufficient material rotation space, and the current of the equipment is too large due to excessive charging, so that the powder and additives are mixed into paste or ball shape, it is necessary to consider increasing the motor power or changing it to a 6-level motor to achieve the mixing effect, such as a normal motor power of 75 kW, The mixing proportion is 375L (500 * 0.75=375), which is more reasonable.
At this time, there is no problem in mixing the powder. If the powder is mixed with additives, the motor power should be increased to 90-110kW, otherwise the motor current is too large to knead during the material mixing process.
