Applied Conveyor proudly distributes Rulmeca rollers and idlers. Heavy duty return and trough rollers, maintanence free, specifically designed for long operating life. Available in diameters: 63, 76, 89, 102, 114, 127, 133, 159, 168 and 194mm. Shafts: 20, 25, 30 and 40mm. Rulmeca idlers have a reputation for long service life and excellent performance in a number of different applications.

 

 

TROUGH ROLLERS

The effectiveness of the PSV roller sealing system provides the solution to the environmental challenges of dust, dirt, water, low and high temperatures or applications where there is a large temperature gap between day and night. The working temperature, with standard greased components is defined as between -20C and + 100C. It is possible to reach temperatures outside of this range using special grease, bearings and seals.

Typical application for the PSV rollers are: 

  • Mines
  • Quarries
  • Cement plants
  • Coal-fired power plants
  • Port installations
     


RETURN IDLERS

The straight tracking of the belt may be compromised by the type of conveyed material, especially when this material is sticky and thereby adheres easily to the belt surface. In this case, material is also deposited on the return rollers that support the belt, adding an irregular addition of scale to the roller itself. As a consequence, not only wear and tear of the belt occurs, but forces are brought into play to move the belt away from its correct track. Return rollers with spaced rubber rings contribute largely to eliminating the build up of scale that forms in certain conditions on the belt surface. The rings are pointed, assembled at intervals, in the central part of the roller, where they have the scope to break up the scale which normally is present at the belt centre; meanwhile flat rings mounted in groups at the extremities of the belt, support and protect the belt edges, also in cases of limited belt wandering. Return rollers with rings should not be used as belt tensioning devices.

 


IMPACT ROLLERS

Impact rollers are used and positioned corresponding to the load points, where the lumps and the weight of material falling onto the belt could in fact cause damage to it. To limit the impact effect of the material onto the rollers, the latter are covered with a series of rubber rings of adequate thickness and resistance. Impact rollers are under stress not only from the load of the material, but also from the dynamic forces as the load falls onto the belt. The impact onto the belt, arising from the free fall of material will be naturally greater than in the case where the material is deflected onto the belt by an inclined plate For the correct dimensioning and the choice of impact rollers in relation to the load check the characteristics of the base roller.


 

MELCO SUPREME

The Melco SUPREME boasts a wide range of superior advantages, features & benefits:

  • Steel tube ensures adequate mechanical strength for heavy duty loads 
  • Ultra thick abrasion and corrosion resistant 12mm thick HDPE sleeve 
  • HDPE contains carbon black increasing ultra violet resistance 
  • Steel and HDPE tube combination provides significantly reduced weight 
  • The bearing housing effectively locks the HDPE tube in position preventing movement along the steel tube    
  • Minimum C dimension decreases load induced shaft deflection 
  • Unique large diameter stoneguard with integral labyrinth design minimises possibility of being jammed by spilt material, and provides additional protection from water and dust 
  • Multi part labyrinth seal protects the bearing from ingress of contaminants 
  • Ultra low running resistance and break away mass reduces power consumption for start up and continuous operation 
  • Machined fi nish ensures LOW run-out, minimizing vibration and noise emission 
  • Castellated HDPE tube is a tight interference fi t on the steel tube

 

TOP THERMOSTATIC ROLLER

Rulmeca is proud to introduce the new TOP roller, a totally thermoplastic roller with the exception of the steel in the ball bearing and the shaft. The new TOP roller has a lower weight with respect to a steel roller (about 50%), which means a lower power consumption during start/stop operation of the belt conveyor and therefore reduction of power requirements on the plant, easier mounting and maintenance operations, preventing back injuries of the operator and guaranteeing a safer intervention, especially in application where roller mounting or replacement might be critical (suspended belt conveyor, difficult access, long conveyors), easier/cheaper transportation. Furthermore the low level of abrasion and corrosion of this roller (wear resistant) guarantees a longer life of the roller and a lower maintenance of the whole plant. The TOP is belt friendly, since HDPE tube will not wear the belt high resistance to chemical agents. It doesn't rust, it is suitable for a wide variety of applications and it has a low noise emission (due to thermoplastic noise absorption).Thanks to the self-cleaning roller surface, there is a prevention of build-up of material, main cause of belt mis-tracking, and less spillage from the belt. The roller low running resistance sealing system means a lower motor torque need in conveyor starts, a lower motor power size, a reduction of energy consumption of the belt conveyor (added effect to that of the lower weight) and a lower belt consumption.


 


TROUGH FRAMES

Standard frames are 450mm to 2000mm, 20, 30, 45 degrees and customs can be made on request. All trough frames are made to fit standard New Zealand rollers.

 

 

 

 

 

IMPACT BEDS

Impact beds are designed with one simple goal – protect the belt.

Features: 

  • Construction makes maintenance convenient and safe
  • Impact beds separate in the middle and the two sides slide apart
  • A complete bar change out takes just one to two hours
  • Impact Bar Supports enhance bar function
  • Made from high-strength steel properly to absorb more impact energy
