Low Shear – High Volume Mixers with Counter-Current Technology.

Lancaster Products L-Series counter-current mixers are equipped with hi-torque, low shear, rotating plow blades. The L-Series mixer can come with muller wheels as an option, which combines a kneading, rubbing, or smearing action of a mortar and pestle along with the intensive mixing of the counter-current system. L-Series industrial mixers can be manual, fully automatic or a combination of both and can be used for research, testing or production.

Lancaster L-Series Mixers are ideal for:

  • Low shear or low energy mixing
  • Suitable for Shear Thickening or Non-Newtonian materials
  • Mixing, slow or delayed chemical reactions
  • Capacities from: 0.1 cu ft to 80 cu ft

TOOLING OPTIONS

Low Shear Tool Action

Lancaster Products engineering staff can assist in selecting the appropriate mixing tools depending on the characteristics of the materials to be processed.

Low Shear tooling options include:

  • Plow action alone, or plow with mulling wheels
  • Fork tines or cutters can be substituted for plows

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.

HOW IT WORKS

The counter-current mixing action of the Lancaster Mixer 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. This results in countless cross-over of layers with maximum particle travel both vertically and horizontally, without depending on free fall.

Depending on the material and application, mulling can be an important addition to mixing. Equipping Lancaster Mixers with muller assemblies imparts a kneading and smearing action of a mortar and pestle needed for some applications such as foundry sands, along with the intensive mixing of the counter-current system.

Synergies Between Lancaster Products, Bradley Pulverizer, and Kercher Industries Lead to Improved Efficiencies and Market Growth

In January of 2020, Lancaster Products/Kercher Enterprises acquired the assets of Bradley Pulverizer and we are thrilled to add over 130 more years of industry experience to our 70+ years. While each will continue to operate as 3 separate businesses, we are already leveraging the benefits of the new acquisition. When Curt Snyder (owner) first explored this opportunity he immediately identified 5 primary synergies between the businesses that would benefit from cross-company collaboration and improve efficiencies to benefit our organizations as well as our combined pool of clients.

In just a short amount of time a strategic plan has been instituted to align the best of all 3 companies with a focus on the following:

    1. Product Line Synergies
    2. Overlap in Customers and Industries Served
    3. Expansion of Manufacturing and Fabrication Capabilities
    4. Leverage Existing Global Sales Channels
    5. Enhanced Business Efficiencies

Case Study – High Shear Mixing of Clay Compositions

High Shear mixers are used in a wide variety of applications in many different industries. Finding the right blend and being able to produce the same mix consistently is the key to success at Highwater Clays, a clay and glaze supplier to the arts & crafts industry. The company has two locations with the main production center located in Ashville, North Carolina. Highwater Clays produces a wide range of clay bodies using fireclays, ball clays, kaolin, and stoneware clays. All the clay bodies consist of complex compositions and must be mixed into one reliable consistency.
