SIG Rubber Conveyor and Elevator Belts
Rubber conveyor belting is the cheapest system to convey bulk solid materials over any distance. It is the topic item of a conveyor system which allows the material handling. All rubber conveyor belts are composed of two different elements:
A central resistant carcass which gives the mechanical characteristics to the product, as tensile strength and elongations. Two main belting families exist: textile conveyor belts and steel cord conveyor belts. See the internal part of the catalogue for a complete description.Two rubber covers, named top and bottom covers, which protect the resistant carcass and characterize the belt, as described in this page. In order to guarantee safety and long life also under hard working conditions, all type of rubber covers are antistatic and ozone protected.
RULMECA Roller and Pulleys
WORLD LEADING MANUFACTURER OF PREMIUM COMPONENTS FOR UNITS AND MATERIAL HANDLING
Experience and innovation
Founded in 1962, the Rulmeca Group has grown to be a leading partner to the global materials handling industry.
With its three product brands, Rulmeca, Precismeca and Melco, Rulmeca Group is the world’s largest supplier of rollers/idlers, pulleys and motorized pulleys for heavy duty belt conveyors for quarries and mining applications and of rollers, drum motors, Drive Rollers 24V for the Intralogistics.
The 17 Production and sales companies all around the globe serve Rulmeca Group clients in more than 85 countries.
Todays movement of goods and bulk materials demand state of the art methods.
The Rumeca is an International leader in the production of components and equipment for all types of conveyors, providing a service based on a specialised technical competence accumulated over 50 years of experience.
The Rulmeca range for belt conveyors in bulk handling comprises:
Steel rollers and thermoplastic rollers, with rubber rings for impact and return stations
Transoms and garland sets for carrying, return and self-aligning stations
Drive and idler pulleys for various applications, with clamping units
Accessories: Belt cleaners, belt covers and impact bars.
Rulmeca production programme of stations is according to the Unified Standards DIN 22107.
On request they can be supplied in different shapes and dimensions according to the standards CEMA, BS, JIS, AFNOR, SANS and ISO-FEM.
The Rulmeca Motorized Pulley was first produced in 1953 specifically for use on conveyors belt applications. A Motorized Pulley is a compact, hermetically sealed, highly efficient conveyor drive unit that would be unaffected by dust, water, oil, grease or other harmful substances. A Motorized Pulley that would be quick and simple to install and require virtually no maintenance.
The experience of more than 6 decades has enabled the Rulmeca Motorized Pulley to be one of the most reliable, effective and safe conveyor drive systems available throughout the world, in applications in all the fields of mining and bulk handling material processing.
Rulmeca Motorized Pulleys are supplied with the degree of protection IP66/67, they are also in compliance with the Safety norm ANSI 535.4 and ISO 3864-2 and have a 2 years warranty.
They are manufactured according to the Council Directives of the European Communities, particularly according to Directive 2006/95/EC relating to electrical equipment and according to Directive 2004/108/EC relating to electrical magnetic compatibility.
Rulmeca new products range for unit handling has been extensively renewed, allowing the Group to move ahead. The range of components for unit handling, all made by Rulmeca, comprises of different rollers and components to make:
- Gravity conveyors
- Chain driven conveyors, with accumulation or with zero accumulation
- Belt driven conveyors, with accumulation or with zero accumulation
- Gravity curves, chain driven curves, belt driven curves
These rollers are all products of high quality and reliability for unit handling in all fields of applications.
Rollers for Gravity Conveyors
For idle roller conveyors, we mean a series of rollers supported by a carrying structure, designed to handle packages by means of thrust or gravity. The Rulmeca rollers, in steel or Polymers, allow to handle units with loads ranging from a few grams to tonnes.
Tube Executions on Request
Tube executions are additional executions on the steel tubes of rollers for both gravity and driven conveyors:
- “E” and “F” execution: grooved rollers for round belts transmission
- “P” execution: PVC covered rollers
- “W” and “H” executions: rollers with guide flanges
- Aluminum flanges
- Sleeves to increase friction
- “R” design: rollers with rubber lagging
- “PU” design”: rollers with Polyurethane lagging
- “T” design: Rilsan coated rollers.
Components for Gravity Conveyors
Components used for drive or gravity unit handling suited to many types of applications.
Rollers for Chain Driven Conveyors
For chain driven roller conveyor systems we mean a series of rollers supported by a structure, suitable for unit handling, driven by chain.
The chain driven roller conveyor systems are used for the controlled handling of a great variety of loads, with regular or irregular shapes, with heavy or light unit weights, rugged or fragile, either horizontally or with a light slope. They are used to synchronize automatic transport systems, as slave systems for assembly stations and operating machines, with continuous, step-by-step or accumulating advancing, and for all those applications where idle roller gravity conveying systems are not recommended.
Rollers for Curves
Curves can be with tapered rollers or cylindrical.
The drive is transmitted with chain loops and the gear motor is typically in a central position.
The driven tapered rollers permit the design of flat curves with reduced dimensions, guaranteeing the regular load movement. For the straight section it is recommended to maintain the same “EL” width of the curves, compatible with the standard length of taper rollers.
The tapered rollers with belt transmission are introduced in the section “Rollers for belt driven conveyors”.
Rollers for Belt Driven Conveyors
For belt driven roller conveyor systems we mean a series of rollers supported by a structure, suitable for unit handling loads which are driven by a belt.
The belt driven roller conveyor systems are suitable for handling a great variety of heavy and light loads of regular or irregular shape.
The system feature is particularly silent running, also at high speeds.
The drive is transmitted with flat-section belt or with belt rings with different sections. In the latter case they can be fit to friction rollers to carry out conveyors with load accumulation.
