Heating Cooling Mixer Combination

Kenneth Heating Cooling Mixer is a combination of heating mixer and cooling mixer for the blending of PVC resin and additives. In order to have the free flowing dry PVC blends for the afterwards melt compounding into PVC products, the pre-compounding of PVC resin and additives via heating cooling mixer has to go through the heating mixing process and cooling mixing process.

 In short, the heating mixer firstly homogenizes the PVC compounds via high speed mixing tools. Meanwhile, the intensive motion not only grinds solids into finer particles, but also cause a rapid temperature raise by self-frictions of compounds. The increase on temperature provides condition for PVC resin to fully absorb liquid additive(plasticizer/oil) and eliminates moisture from the compounds. The mixtures after heating mixing process are well dispersed, homogenized fine dry compounds except hot and not stable.

Thus, a right after cooling mixing process is needed to eliminate electrostatic charge on polymers caused by high friction mixing, cool down the hot compounds to avoid over heat of temperature sensitive compositions, increase the free flowing property and minimize the tendency of agglomeration. Mixtures after the cooling mixing process are final stable free flowing fine PVC dry blends which could be stored or further processed into PVC products right away.

Typically, the heating mixer is set back over the cooling mixer so that hot mixtures after heating mixing could be discharge into cooling mixer directly in time. Considering the synchronization of heating mixing process and cooling mixing process, the mixing tank capacity of cooling mixer is usually 2-4 times of heat mixer for sufficient cooling capacity within a batch cycle of 6-8 minutes.

Kenneth Heating Cooling Mixer has 2 types of combinations: SRL-Z vertical mixing unit and SRL-W horizontal mixing unit for PVC applications. Both vertical and horizontal mixing units have the following features:

• Suitable for a wide range of applications such as heating, agglomerating, bonding, grinding etc
• Process optimized mixing tools and process tailored configurations
• Durable and reliable mechanical drives and transmissions
• Excellent filters for dust control and de-humidification of mixtures
• Diverse optional auxiliaries for customized requests
• High cooling efficiency of optimized cooling tank and lid
• Optimized design for easy cleaning and maintenance
