Batch Mixers
Reliance High Intensity, Medium Intensity, and Low Intensity Mixers are Batch Type Mixers. All ingredients must be added, mixed, and discharged before another batch can begin. All ingredients can be added prior to starting the motor or can be added throughout the mixing cycle. The ingredients are pre-set and weighted prior to introduction into the mixing vessel. A Batch Mixer, as is implied by its name, mixes singular batches at a time. This is in contrast to a Continuous Mixer where material is added and discharged without any break in the mixing process.
In the case of Color Concentrates and Color Masterbatch manufacturers, all of the material is added at one time prior to the mixing cycle. The material is mixed until all material is homogenously distributed and the proper characteristics are met. Mixing speeds are kept low to keep material degradation to a minimum. Mixing is based primarily on an established to ensure all material is homogenously distributed.
In the case of PVC end products such as pipe, siding, conduit, etc., the ingredients are added through the cycle of the batch. Resin is added to the mixer and heated to a set temperature. Plasticizers, modifiers, heat stabilizers, fillers, and other ingredients are added throughout different temperatures of the batch. Once the material reaches a set temperature, say 220 degrees F, it is discharged from the High Intensity Mixer in to the Horizontal or Vertical Cooler.
Industrial Spice & Food Batch Mixers can be horizontal or vertical in construction. The horizontal units will be either Paddle Mixers or Ribbon Mixers. The Paddle Mixers can be supplied with chopper assemblies to help facilitate in break-down of clumps. The vertical units either have a tool coming from the top lid assembly as is in the case of Dough Mixers or have a bottom entry shaft with the tooling sitting on the shaft seat. The vertical units can also have chopper assemblies to facilitate break-down of clumps.
