Rollers for belt conveyors

Rollers are considered a high investment in the overall requirement needed in the design of a belt conveyor installation. It is also important to underline that choosing high-quality rollers for belt conveyors equals to granting a massive improvement in terms of production, longer working life and the reduction of machine downtime during plant’s activities. It is common knowledge that life and efficiency of modern belt conveyors depend significantly on the choice of quality rollers, manufactured using highly selected materials and accurately designed. In these terms, it is also crucial to evaluate the sealing system that protects roller’s bearings. RULMECA’s rollers for belt conveyors are the result of special attention granted to every single manufacturing phase: from preliminary research to design, from production to strict laboratory tests. Rollers for belt conveyors by RULMECA are manufactured according to all known national and international standards, such as ISO, UNI, DIN, AFNOR, FEM, JIS and CEMA.


The benefits of choosing rollers for belt conveyors by RULMECA

The benefits that come from choosing rollers for belt conveyors designed and manufactured by RULMECA are numerous:

  • Long life service
  • High-quality components and materials
  • Optimal efficiency
  • Economy of use

Our rollers for belt conveyors are also submitted to a series of tests performed in our laboratory test rooms. We have created a dedicated area, equipped with specially designed machines that verify design and development of rollers for belt conveyors. Our tests are varied and allow the examination of different characteristics for each roller type:

  • Load and life capacity
  • Hermetic sealing of rollers, both stationary and during rotation
  • Hermetic sealing in dusty environments
  • Ambient temperature withstanding: from -70°C to +200°C


How to select rollers for belt conveyors

When it comes to the choice of rollers for belt conveyors. This crucial phase takes several factors into consideration. The main ones include:

  • abrasive and corrosive characteristics of the conveyed material

For example, abrasive materials such as granite, clay or ferrous minerals might need the use of heavy rollers such as PSV and MPS, coupled with a large tube diameter to grant a minor contact between the roller surface and the conveyor belt. The conveyor transport of corrosive materials like chemicals or salt, on the other hand, requires that rollers are protected or manufactured using appropriate materials in terms of resistance to the corrosive substances. These materials can include stainless steel, standard steel lagged with rubber/other anti-corrosive materials, Defining this load is the result of a specific calculation made by project designers, and it includes typical values such as:

  • Belt conveyor speed
  • Conveyed material type, lump size and angle of repose
  • Troughing set angle, type and pitch
  • Equipment daily working hours
  • Environmental conditions
