The CPM/ROSKAMP Roller Mill has established a strong market position as a machine for the production of layer mash feed with an extraordinary good structure. The CPM/ROSKAMP Roller Mill series have a heavy duty design and are available with 1, 2 or 3 roller pairs. A roller pair is driven at one side by an electrical motor,while at the other side a speed difference between the rollers is created by V-belt reduction. Due to the cutting action of the rollers a 40 to 60 % energy saving can be achieved in relation to the traditional Hammer mill. Also a most homogeneous mash structure with reduced fine content is acquired, without the presence of unbroken grains. This results into improved mashfeed flow characteristics.
The CPM/ROSKAMP Roller Mill is being applied in a wide range of particle reduction applications out side the Feed Milling Industries. Within the feed milling industries developments can be found where the efficiency in particle reduction by means of the roller mill is further explored. In the combined grinding process the Roller Mill is being applied in two ways. First for the production of layer mash feed with an excellent structure and secondly pre-grinding the mash feed for the Hammer mill. The pre-grinding increases the capacity of the Hammer mill between 40 and 60% and at same time reduces the total energy consumption by 20%. The CPM Roskamp Roller mill is designed for the most demanding cracking and grinding operations. Roll corrugations and roll speed differential ratios are available to match any operating conditions. Unique bearing slides assure accurate, consistent production. All machine functions adapt easily to full-automation. The rugged construction guarantees maximum performance around the clock.
ROLLS & SHAFTS
Rolls are of the highest-quality straight carbon clear chill cast iron. All rolls are cast, machined, and ground to the best technical specifications. Depth of chill is minimum of 16 mm (.625 inches). Allows custom corrugating for specific product configurations. Large diameter shafts are high tensile, high yield alloy steel. Roll face and shafts are cylindrically ground to assure concentricity.
Roll shaft bearings are self-aligning spherical roller bearings. Tapered bearing bore with adapter sleeve provides positive locking fit with shaft to prevent shaft
fretting. Bearings and housings need not be removed during recorrugation. All bearing lube ports are easily accessible for maintenance.
BEARING HOUSINGS & SLIDE BLOCK
Bearing housings and slide block assure positive roll tram (maintain rolls in same horizontal plane for positive particle size control and assures best roll life). External tension and pressure members contain roll separating forces and maintain parallel and tram.
Roll adjustment is made by machine screw jacks. It provides accurate, repeatable gap adjustment and assures parallelism of rolls. Air motors provide rapid roll adjustments. Manual handwheel is standard for fine control. Optional full feature design provides remote roll adjust with digital read out. Remote roll stop offers maximum protection.
V-Belt Inter-Roll drives for silent operation in lower horsepower applications (up to 37 kW per pair). Belt tension can be adjusted without removing the guard. Heavy duty idler arrangement keeps belts positively tensioned. Gear Box Inter-Roll Drives for higher horsepower applications (up to 75 kW per pair). V-belt drive to input shaft of gearbox provides shock absorbing action.
