The Bauermeister Gap Mill is a unique design for fine grinding down to the 25 µm area. The proven design features an adjustable grinding gap between the conical shaped rotor and a corrugated baffle. This combination delivers improved grinding performance and accurate particle sizing without screens.
The conical shape of the rotor allows the mill to impact the product with increased tip speeds as the particles pass through the grinding area. For example, at 123 m/s medium tip speed, particles enter the grinding area with a tip speed of 115 m/s and this increases until the tip speed exceeds 130 m/s at the exit of the grinding area. This allows the mill to grind particles finer in one pass where competitive mills often require internal recirculation to achieve the same results.
The lower section is designed to allow ground product to be discharged out of the bottom by gravity within the air flow, where it can be pneumatically conveyed. The reversible grinding elements on the rotor are u-shaped and cast from high quality alloys for increased durability.
The Bauermeister Gap Mill is available in four production sizes. The medium diameter of the rotors are 200 mm, 400 mm, 800 mm and 1,200 mm. Depending on the product, capacities range from 20 lbs/hr up to 20,000 lbs/hr.
