Lancaster Products manufactures high shear mixers for the efficient preparation of bentonite bonded molding sand. The Lancaster low intensity muller style mixers are used for molding sand preparation in the foundry industry.
A complete molding sand system design and supply by Lancaster Products can provide a single source solution for the end foundry user. Click here to learn more about our high shear mixers.
The advantages of the Lancaster Products system:
- Excellent flowability of mixed sand
- Uniform strength values due to the consistent mixing process
- Compactability requirements for the sand can be met on a consistent basis
- Distribution of water in an efficient manner when added to the mixture
- Consistent mixing of the return sand, additives and new sand in the Lancaster High Shear Mixer
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.
