Boston Shearmill High Intensity Wet Milling, Homogenizing & Particle Reduction Outperforms inline mixers, conventional shearpumps and colloid mills The Boston Shearmill is our ultimate machine for providing high to extreme shear rates and tip speeds for maximum droplet and particle size reduction. If your process requires milling of soft particles to under 1 micron, or hard particles down to 1-2 microns, the Boston Shearmill will meet this criteria, often with just a single pass at high production rates! The Boston Shearmill has replaced colloid mills and homogenizers where submicron processing was not necessary. Existing installations include tomato paste enhancement and standardization, ketchup and mustard production, salad dressing and mayonnaise, pet foods and treats, soups and sauces, flavor emulsions, pharmaceutical preps, polymers and more. Each rotor/stator shear head has a double ring design, resulting in three distinct, high intensity work zones at each shear head location (up to 3) where the mixture passes. Models with three shear heads provide nine high shear work zones to handle your toughest processing needs. This residence time between the stages allows for creating tremendous mechanical and hydraulic energy for applying maximum shear forces into the product. The best built, heavy duty, all purpose inline milling machine on the market • Standard shear head grades include coarse, medium, and fine • Special purpose heads available for texturizing and blending without damaging or altering solids and desired consistency • Provides 5 to 165 gal. product throughput, depending upon feed rate and viscosity • Features single mechanical quench seal rated for 700 psi, (double seal optional), and complies with 3A (#36-01) standards Your Mixing Technology Partner

The Boston Shearmill BSM-25, 37 & 60 A wet mill should be judged by how well it does its job, but equally important is that the machine be strong enough to work day after day and year after year, with as little need for service as possible. The Boston Shearmill is designed for 24 / 7 operation, through your most critical processing schedules when downtime is not an option. The Boston Shearmill combines a well-proven rotor-stator principle with the latest innovations in seal design and bearing support technology. The design is deceptively simple but exceptionally durable. The engineering...
