Our last post focused on our experience in concept testing and how it applies to our high shear mixer sample testing process. This post will dig in a little deeper and provide insight into the breadth of data we provide to our customers when they commission Lancaster Products to provide sample testing for them.
Over the past 30 years, we have collaborated with our customers to perform proof of concept testing in our K1 laboratory mixers for thousands of materials samples. The desired outcome of the testing is customer dependent but typical requirements are along the lines of pelletizing/granulating to specific size ranges and desired yields, mixing to achieve homogenization, or reduced reaction times of existing processes. Outcomes provided are 1) proof of concept in achieving the desired product, and/or 2) optimization of the current mix processes. Our engineers perform the tests in our controlled laboratory, log all key information in our database, and share all data with our customers for future reference. Below is a list that summarizes some of the information we collect during every test run we perform:
Introducing Lancaster Products High Shear Counter-Current Mixer Recipe Development, the first in a category of posts designed to provide insight into our deep experience in developing thousands of pelletized and granulated formulations over the past 30 years.
We develop custom recipes or mix designs for our customers that are rooted in our deep mixing and pelletizing experience. Because every customer’s materials, parameters and processes are different, each requires a unique mix design. In performing proof of concept testing, we have worked with our customers on a wide variety of materials and binder combinations across many different industries. While specific formulations belong to our customers, we have learned a tremendous amount from our experiences with various materials and we wanted to highlight the science that goes into every formulation developed by our materials processing engineers.
High shear counter-current mixers from Lancaster Products simply employ the most effective mixing technology available.

Binders are a key ingredient in agglomerating, granulating and pelletizing applications. Considered an inactive ingredient, Binders are critical in allowing for agglomeration and holding the structure of the pellets together. Many of our customers are pleasantly surprised of how efficiently the Lancaster High Shear Counter Current Mixer can pelletize utilizing low amounts of binders when compared to alternate methods of granulation. The advantage lies in the Lancaster Mixer’s ability to rapidly homogenize tiny amounts of minor ingredients into large amounts of majors. Because the binder is so efficiently dispersed throughout the mix, only the optimal amount of binder is used. Less effective mixing techniques require more binder than in a Lancaster Mixer, because the binder is not as effectively dispersed throughout the mix.
Lancaster Products has introduced design enhancements to the K-Series High Shear Counter Current Mixer line. Through our continuous improvement initiatives our engineers identified various areas of design refinement focused on improving our customer’s maintenance experience, reducing manufacturing time and enhancing the mixer’s overall design. We are featuring our new and enhanced discharge assembly design.
Lancaster Product engineers created a simple yet elegant solution to improve the discharge valve design by moving from a keyed assembly to a keyless locking device. The new design is less complex than its predecessor and performs better than the previous discharge style. The new keyless connection enhances performance over the old design and will be easier to maintain and service.
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.
Since the introduction of the original K-series mixer in 1986, Lancaster Products High Shear Mixers have been designed to produce the best mixing and pelletizing results for our customers. Lancaster Mixers superior performance is due to our multi-tool configuration, counter current mixing action and variable tooling speed capability.
Multi Tool Configuration
Lancaster Mixers can be configured with three independent variable speed mixing tools: the mixing rotor, the plow and the rotating pan. These three tools work in concert to provide the best mixing results. The primary mixing tool is the high-speed rotor. The plow and rotating pan both work to move material into the main rotor’s path. The three mixing tools are so efficient at mixing, there are no dead spots inside of the mixing cavity and every piece of material passes through the mixing rotor every few seconds. Additionally, a sidewall scraper is positioned against the pan sides to prevent caking and buildup of material on the pan itself.
