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
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
