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.
We are excited to announce several recent improvements to the design of our low shear mixer product line. These mixers are often pushed beyond the limits of other mixers due to their widespread use in mixing dusty, abrasive, corrosive, highly viscous or explosive materials. The enhancements listed below were designed to improve the performance of our low shear mixers and to minimize maintenance and repair costs, which lowers the overall lifetime cost of ownership for our clients.
- Split drivetrain: pan and tooling on separate drives
The counter-rotating pan and tooling are now operating on separate drives allowing for individual control of tool and pan speeds. This simple split drive design provides increased flexibility to customize mixing recipes for different materials as compared to a single vertical shaft. Maintenance and trouble- shooting of issues relating to the pan or tooling also become easier.
BRADLEY PULVERIZER ACQUIRED BY LANCASTER PRODUCTS OWNER
Allentown, Pennsylvania, January 17th, 2020 – Bradley Pulverizer is pleased to announce new ownership. Lancaster Products & Kercher Enterprises’ owner Curt Snyder acquired the assets of Bradley Pulverizer through an affiliate effective on January 14th, 2020. Bradley Pulverizer specializes in the design, manufacture, and supply of pulverizing systems for fine and semi-fine grinding of hard, friable, abrasive materials for various applications throughout the world.
In addition to the rotating pan, all high shear mixers manufactured by Lancaster Products larger than a K3.5 have two independently motor driven mixing tools inside the pan which are responsible for proper mixing, pelletizing, and granulating of materials: the plow and the high speed rotor. The plow continually sweeps the entire surface of the pan bottom to prevent material from accumulating on the bottom and enhances the overall mixing action. However, the most important tool of all is the high-speed rotor, which rotates counter direction to the pan causing a shearing action inside of the mixing cavity. This high-speed rotor not only agitates the mixture, but significantly influences the control of the entire process. While there are just two main style of standard rotors, we can custom configure the rotor to optimize all mixing processes.
Traditional processes for manufacturing fertilizer require many steps and different types of equipment. It is common for systems to include multiple dryers, a mill/pulverizer for size reduction of dried material, pin mixer/pug mill for mixing of additives and raw materials, a pelletizer and multiple conveyors to facilitate the process. If this seems like a complex process that requires high levels of work, energy and maintenance, we agree.
Lancaster Products engineers can optimize existing complex fertilizer pelleting processes or design new streamlined systems to help you realize multiple benefits, including a reduction in physical footprint and an improvement in the characteristics and reproducibility of your pelletized product. By utilizing a Lancaster Products K-Series High Shear Mixer to replace a mill and disc pelletizer, you not only reduce system complexity but also gain the ability to begin processing with raw materials at higher moisture levels. The counter-current mixing action in a Lancaster Mixer allows for one-step mixing and pelletizing with rapid mix times.

Many reasons compel industrial operations to enlarge solid particles for handling. Some objectives may be: enhancing flow properties, recycling, de-dusting, densifying, freezing ingredient distribution, improving mold filling properties, etc. Size–Enlargement in the powder technology context include: agglomerating, pelletizing, granulating and briquetting. This article deals with particle enlargement generally through a snowballing mechanism, with some shear action, but without the application of high pressure or extrusion.
Most powders having the ability to fuse, or slightly dissolve in the presence of a liquid, can be granulated quite easily. Others may be coaxed to form granules by the introduction of some suitable binders. The binders may act as a medium for the solid particles to adhere to each other by modifying interfacial activities. Some may form a matrix to capture the particles. Others may involve chemical reactions to achieve the objective.
Synergies Between Lancaster Products, Bradley Pulverizer, and Kercher Industries Lead to Improved Efficiencies and Market Growth
In January of 2020, Lancaster Products/Kercher Enterprises owner, Curt Snyder, acquired the assets of Bradley Pulverizer and we are thrilled to add over 130 more years of complementary 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 Snyder 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:
