CPM ROSKAMP - Roller Mill
The CPM ROSKAMP Roller Mill has established a strong market position as a machine for the production of mash feed with an extraordinary good structure. The rugged construction guarantees maximum performance around the clock.
Energy Efficient Grinding
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 mash feed 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.
Bearings
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 re-corrugation. 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
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 hand wheel is standard for fine control. Optional full feature design provides remote roll adjust with digital read out. Remote roll stop offers maximum protection.
Inter-Roll Drives
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.
Main Drive & Motor Base
The main drive (motor to rolls) is 5V section V-Belt design. The motor base is modular to accept standard motor frames.
Rigid Roll Housing is precision fabricated for maximum strength. Machined slide block ways assure roll parallelism and tram. Each housing is of dust tight construction with sample ports. Roll end seals are externally adjusted.
Roll Feeder
The roll feeder is standard. It features a steeply angled housing for cleanliness. Feed roll is corrugated to fit products processed. Independent drive and positive gate action easily adapt to full automation control. (see separate product sheet). Roll Feeder with Adjustable Gate Jack screw arrangement provides a simple means of adjusting the feed gate position. Feed rate can be accurately controlled either locally, or from a remote location. Digital read out of feed gate position allows the mill to be controlled from any location. Can be fit with load controller to automatically adjust the feed rate to changing conditions.
Vibratory Feeder
Optional Vibratory Feeder controls feed rate and distribution across the roll length. Vibratory feeders are recommended for hard to feed materials with poor flow characteristics. Feeder controls can be fitted with mA (milliamp) sensitive control circuits in process plants, employing multiple machines.
Infinite Gap Control With Digital Read Out
Optional full feature units are fit with optical encoders, provide a digital read out of the roll position. Rolls can be remotely opened and closed, and different grinds selected with the turn of a switch. This option is highly recommended for all fine grind applications.
Magnet
Heavy Duty permanent magnets pick tramp iron from the product stream. Magnets swing out of the feeder housing for ease of cleaning.
Controls and Console
Pre-wired control panel simplifies mill installation. Panel includes roll feeder controls and roll position controls. Feeder roll motor starter is included. Pre-wired control panels do not include mill motor starters or push button operators.
Optional console provides a convenient location to mount the electrical controls.
CPM Roskamp Series
CPM Roskamp Roller mills are made in a variety of sizes. For Special applications additional models are available.
