IMPORTANT! ECCENTRIC AND CONCENTRIC ROLLER AXLE SHAFTS HAVE GREASE NIPPLES FITTED AT THE EXPOSED END OF THE SHAFT, THIS IS TO PERMIT THE ROLLER CAVITY TO BE FILLED WITH GREASE, AND PROVIDES A RESERVOIR OF GREASE TO LUBRICATE THE ROLLER BEARINGS.
One or two shots of grease per shift is usually adequate to maintain the reservoir, if however, the roller has been removed or replaced then it will be necessary to apply sufficient grease to fully recharge the roller cavity. The roller cavity is full when grease emerges from the gear end of the roller; a groove is present in the back of the rear roller bush item 26 to permit this, the grease groove also provides lubrication for the roller gears. During operation as the temperature of the machine increases the lubrication grease will soak into the porous bronze bearing as part of the lubrication process, therefore it is important to always have a clean supply of grease in the roller cavity.
If rollers are not greased sufficiently rapid wear will occur to the roller bushes and roller shafts and usually this occurs first at the gear end of the rollers thus creating a tapered gap between the rollers resulting in a poorly cleaned casing and rapid gear wear. The illustration below shows typical roller shaft lubrication points as provided on all SSD casing cleaning machines.
IN THE INTERESTS OF HYGIENE AND GOOD HOUSEKEEPING AT THE END OF EACH SHIFT THE MACHINE OR LINE AND ITS EQUIPMENT MUST BE THOROUGHLY CLEANED.
Generally speaking, the rollers are self-cleaning and will be relatively clean if the machine is allowed to run for 5 minutes, after the last runner has passed through, with the spray pipe left in the ‘on’ position. After the machine or machines have been switched off, isolate all machines from the electrical supply before attempting to clean the equipment.
The machines should be washed with a mild detergent and a soft brush; care should be taken to ensure that no finished product is present in the tanks or in the vicinity of the machine or line before the detergent is applied.
The residual soap or detergent should be flushed away with warm water at a maximum temperature of 55ºC. The inside of the roller guards is cleaned in the same manner. It will be necessary to occasionally remove all of the fixed guards and remove any residual contamination that has accumulated in areas that cannot be washed with a hose. The frequency at which the machines are stripped down for cleaning will be determined to suit individual operations.
DO NOT USE HIGH PRESSURE HOSES OR STEAM TO CLEAN THIS EQUIPMENT; THIS WILL CAUSE SEVERE ROLLER DAMAGE.
