PSV Rollers Manufacturing Process Tubes are cut true and square by fully automatic Comecel rotating head parting off machinery to very close tolerances These are then MIG welded to the housings by means of purpose built double ended automatic self centralising welding machines to keep radial tolerances to an absolute minimum The welded shell is what we call a UNIBLOC construction and gives a strong and watertight enclosure The spindles are cut and machined on fully automatic double headed sliding headstock CNC s to achieve true and accurate fits within the bearings and seals and accurate fitment into whatever mounting elements will be present Each roller is then assembled on our purpose built presses First a nylon back seal prevents any foreign particles or moisture affecting the bearing from within the 6 shell The bearings are pre lubricated with the correct amount of approved grease and pressed into the housing Labyrinths are also pre greased and then also pressed into position as is the steel cover The bearing assembly is held in position by means of heavy duty circlips Further to the above a stone guard is fitted which acts as a highly efficient first barrier to aggregates down to a millimetre in size A very low friction anti abrasive rubber lip vee ring seal mounted behind the stone guard stops the ingress of any liquids or moisture and also acts as a flinger Following assembly the rollers are painted one coat of black primer applied through our electro static paint booth and then packed in cases or on pallets for onward delivery

Special Applications With belt widths and speeds increasing to cope with the higher tonnages that are now being demanded the call for the design of high duty and special purpose sets has also increased Our experience within Rulmeca enables us to put forward bespoke designs to work with unusual and demanding applications where standard equipment would not normally fit These can come in the guise of 2 3 4 and 5 roll trough sets garlands and 2 or 3 roll return sets We utilise CAD in the design of special transoms and when coupled with the correct specification of roller needed from the vast range of sizes available we can offer specify and guarantee for each individual application 26

Where there are poor loading conditions or indeed where the belt itself is in a poor condition the tracking of trough belts can sometimes prove troublesome An answer in many cases is the fitment of self aligning or self centralising sets which can be used on both long and short conveyor stretches These units work over a central slewing ring mechanism along with guide rollers or brake rollers to keep the belt in line and therefore reduce spillage and undue wear Heavier loads and higher speeds can be catered for by providing wider sets with multiples of rollers to spread the load over more bearings The use of 5 rollers can also enhance the control of spillage by allowing higher wing roller angles 27

Motorized Pulleys for Belt Conveyors General Description The Rulmeca Motorized Pulley was first produced in 1953 specifically for belt conveyor systems The aim was to produce an extremely compact totally enclosed and highly efficient belt conveyor drive resistant to dust water oil grease or harmful substances A Motorized Pulley which would be quick and simple to install and would require virtually no maintenance These aims were achieved and today the Rulmeca Motorized Pulley is considered to be one of the most reliable and effective belt conveyor drives available throughout the world The Motorized Pulley is a highly efficient geared motor drive which is hermetically sealed within a steel cylindrical shell The shell which is usually crowned to ensure central belt tracking is fitted with bearing housings incorporating precision bearings double lipped seals and rotates about a static pair of shafts The motor stator is fixed to the shafts and the motor winding cables pass through one of the shafts eliminating the need for slip rings and brushes The squirrel cage induction motor manufactured in steel laminate is machined concentric to high tolerances and designed to give 200 starting torque for 3 phase versions The rotor pinion is coupled directly to the gearbox The gearbox transmits torque to the shell through a geared rim and provides a highly efficiency motor with very little frictional losses The Motorized Pulley is oil filled which acts as both a lubricant and coolant Heat is dissipated through the shell and the conveyor belt All vital parts are CNC machined 28 The Rulmeca Motorized Pulley is supplied as standard with Rulmeca Motorized Pulleys are manufactured according to the Council Directives of the European Communities Machined mild steel crowned shell The CE marking is according to Directive 73 23 EEC relating to electrical equipment and according to Directive 89 336EEC relating to electrical magnetic compatibility and amendments Electric motor manufactured in accordance with IEC 34 1 EN60034 1 VDE 0530 Class F insulation according to IEC 34 1 EN60034 1 VDE 0530 Most international voltages Standard voltages supplied with 10 tolerance in accordance with IEC 38 Factory oil filled and tested Degree of protection IP66 67 EN60034 1

Motorized Pulleys for Belt Conveyors Features and Benefits of Rulmeca Motorized Pulleys Purpose built design The Rulmeca Motorized Pulley has been specifically designed for belt conveyors Totally enclosed The motor gearbox and bearings are totally enclosed and sealed inside a steel shell therefore they are unlikely to fail due to harmful environmental conditions such as water dust grit chemicals grease oil etc Space saving design Because the drive unit and the bearings are mounted inside the Motorized Pulley shell it takes up much less room than a conventional drive No need for costly extras like chains v belts couplings bearings support structure and special guarding Crushing Screening Safety The Rulmeca Motorized Pulley is probably one of the safest drives available because the motor is completely enclosed and the external shafts are always stationary The only moving external part is the Pulley shell Low purchasing and installation cost The Rulmeca Motorized Pulley is quite often less expensive than a conventional drive because it has fewer parts which reduces conveyor design and purchasing costs It is also much quicker and easier to install certainly less than a quarter of the time needed to fit an exposed system Potash Fertilizer Low maintenance cost The end user also benefits from the Rulmeca Motorized Pulley because it requires no maintenance other than the recommended oil change every 20 000 hours Oil changes can now be increased up to 50 000 hours with the use of synthetic oils Efficiency The Rulmeca Motorized Pulley usually has a much higher efficiency from electrical motor to shell pulley face than conventional drives because it has fewer frictional losses and therefore efficiencies of up to 97 can be achieved Cleanliness Because the Rulmeca Motorized Pulley is totally enclosed it cannot contaminate any special conveyed materials or items such as electrical components plastics and any other materials that must be kept perfectly clean during handling Recycling 30 Aesthetic appearance If installed correctly the Rulmeca Motorized Pulley always looks good Due to its compact size and smooth lines quite often the Motorized Pulley is out of sight because it is hidden within the conveyor frame Thermal Protection All three phase Rulmeca Motorized Pulleys are protected by our thermal protection switch This heat sensitive bimetal strip is built into the motor windings to protect the motor from overheating The thermal protector must be connected to a normally closed circuit Weight saving and distribution Often the Rulmeca Motorized Pulley is lighter than conventional drives and often it is possible to therefore reduce the cost of the conveyor structure Weight distribution is even within the conveyor frame Variable frequency converters All Rulmeca Motorized Pulleys with 3 phase motors are easily controlled by variable frequency invertors working in the 15 Hz to 65 Hz frequency range Fewer parts A Rulmeca Motorized Pulley consists of the drive and two fixing brackets Conventional drives can require up to 8 or more separate components most of which have to be purchased from different suppliers or manufactured specially Low noise Thanks to the totally sealed enclosure and high quality gears the Rulmeca Motorized Pulley runs almost at a whisper a very important fact in today s modern site and plant environments The Rulmeca Motorized Pulley the ideal drive unit for all conveyors Fit it and forget it
