Features
- Rolls - The rolls are either 5" diameter by 12" long or 6" diameter by 14" long on the grinding surface. The inside of the roll is machined concentric to the roll surface to insure uniform cooling and material transfer. Standard rolls are constructed for hardened steel (stainless steel rolls are an option). Rolls can also be ceramic coated, tungsten carbide coated, etc...
- Cooling - All three rolls are water cooled with individual valves to control the flow of water. Thermometers installed in the waterbox to measure outlet water temperature is an option. Digital temperature readouts mounted on the control panel is another option, as is an automatic temperature control system.
- Adjustment - The mill has four (4) point adjustment which can be either manual roll set, manual-hydraulic roll set, or electrohydraulic roll set. The electrohydraulic system offers the "quick release" feature which allows the rolls to be opened and closed, without resetting the roll pressure knobs. This means that the rolls can be opened for cleaning and then closed again, duplicating the previous setting.
- Safety Feature - This mill is equipped with a safety system that is designed to "fail" if any foreign object passes through the rolls. This minimizes damage to the rolls and other component parts of the mill. The manual and manual-hydraulic roll set units have shear pins. The electrohydraulic system has an overpressure dump system.
- Base - The base of the mill is fabricated from stainless steel. This design makes for an excellent appearance and very easy cleanup.
- Apron - The apron is constructed of stainless steel. Positive tension of the knife against the takeoff roll is maintained by a weight located inside the pedestal cabinet. The tension is adjustable. By turning the apron lever, the tension on the apron is released and the apron can be removed for cleaning. The apron blade (or knife) is thin and flexible. It can be removed without the use of tools. The standard knife is constructed of spring steel with a single bevel.
- Endplates - This mill can be supplied with two (2) types of endplate systems. The first system utilizes endplates that ride on the roll journals, allowing for "mixing" on the rear two rolls. The second system utilizes endplates that ride on the "flat of th roll", and they are adjustable to control the spread of material across the grinding surface of the rolls. In both systems, the endplates are easily removed for cleanup. Endplates are constructed of bronze with various plastic materials as an option.
- Gears - The machine is supplied with spiral cut cast iron gear and steel pinions. This gear train has been designed for smooth and quiet operation.
- Bearings - The mill has antifriction roller bearings fitted in self-aligning roll boxes. These boxes are designed to prevent the entrance of foreign matter.
- Motor & Drive - The standard motor supplied with the mill is a single speed TEFC motor (2HP on 5"x12" mills and 3HP on 6"x14" mills). Prewire options include varispeed, braking for safety, explosion proof electrics, etc... The power is transmitted to the rolls via a timing belt drive.
