Low Shear Mixers

Our L-Series, Hi-Torque, counter-current, industrial mixing equipment is equipped with hi-torque, low shear, rotating plow blades that can have associated muller wheels.

  • Used for low shear or low energy mixing
  • Mixing, slow or delayed chemical reactions
  • Capacities from: 0.1 cu ft to 80 cu ft
  • Material testing available

Equipping our material mixing equipment with muller assemblies imparts the kneading, rubbing, smearing action of a mortar and pestle along with the intensive mixing of the counter-current system. Lancaster Hi-Torque L-Series Mixers range in capacity from a minimum 1/20 cu. ft. for the Model PC to a maximum 80 cu. ft. for the Model 108.

Low shear mixers can be manual, fully automatic or a combination of both. This industrial mixing equipment can be adapted to process dusty, abrasive, corrosive, highly viscous or explosive materials and can be used for research, testing or production.

Look to Lancaster's advanced techniques for mixing solids or solids with liquids. It could save you money, time and effort. Lancaster Hi-Torque L-Series counter-current industrial mixing equipment can handle materials from powders to pastes – regardless of differences in particle sizes, shapes, weights and hardness.

How It Works

Lancaster's counter-current mixing action is widely accepted as the most effective technique for consistent uniformity and thoroughness. Simply stated, counter-current action occurs when the pan rotates in one direction, while the mixing tools rotate in the other. The rotating mixing pan conveys the material to the counter-rotating tool assembly located off-center of the pan. This results in countless cross-over of layers with maximum particle travel both vertically and horizontally, without depending on free fall.

Construction

Lancaster L-Series Hi-Torque counter-current mixers are equipped with hi-torque, low shear, rotating plow blades that can have associated muller wheels. Our low shear mixer design include muller assemblies, which impart the kneading, rubbing, smearing action of a mortar and pestle along with the intensive mixing of the counter-current system.

As designers and manufacturers of low shear mixers, we can assist you in selecting the appropriate mixing tools depends on the characteristics of the materials. There is choice of mixing by plow action alone, or mixing with mulling action. Fork tines or cutters can be substituted for plows where required. When mulling action is desired, the mulling wheels are adjusted above the mixing pan bottom to clear the largest grain size. This feature prevents particle size change or destruction.
