Rollers are the most important components of material handling and conveyor systems as represent a high investment in the conveyor systems overall. Rollers affect the conveyor efficiency by supporting the belt and guaranteeing they rotate freely and easily under load. As rollers represent a considerable value of the whole cost of conveyor systems, the correct sizing of them is fundamental to the guarantee of the plant efficiency and economy in use.
Based on years of experience in the material handling systems, VOC’s experts, fully aware of customer requirement, are ready to consult you to design and find the best Roller type that guarantee an adequate working life. It has been well proven that conveyor life and efficiency depends to a great deal on the choice of quality rollers, accurately manufactured using highly selected materials.
There are many roller manufacturers all around the world. Among them, German manufacturer Rulmeca with more than 50 years in the field of balk material handing is one of the market leaders due to the approved quality, vast product range, innovative technology and their customer support all around the world.
The Rulmeca rollers are designed and manufactured according to all known national and international standards: ISO, UNI, DIN, AFNOR, FEM, BS, JIS, SANS and CEMA and are in conformity to the norms of the "ATEX" 94/9/EC Directive, Ex Group I, category M2 (for Mines), Ex Group II, category 2G (for Gas) and 2D (for Dust), Ex Group II, category 3G (for Gas) and 3D (for Dust).
PSV
particularly suited to conveyors that operate in very difficult conditions, where working loads are high, and large lump size material is conveyed; and yet, despite these characteristics, they require minimal maintenance. These rollers are suitable for all bulk handling applications in different applications such as mines, quarries, cement works, coal-fired power plant and dock installations. This type has a shaft diameter range from 20 to 40 mm and tube diameter range from 63 to 194 mm.
Impact rollers
These rollers designed to resist and absorb the pressure given by the impact of materials onto the belt and consist of the basic steel PSV rollers design.
Return rollers with rings
These return rollers are used to eliminating the build-up of material which particularly is present in the belt center.
Return rollers with helical rubber rings
Return rollers used to support the belt when the material being conveyed is very viscous by reducing the deposit of material on the surface of the dirty side of the belt.
Belt tracking roller
The belt tracking roller responds instantly to the misalignment of the belt
MPS Rollers
These are light duty economical rollers.
RTL Rollers
These Rollers used in the movement of small or light loads even in medium severe environmental conditions.
DSK rollers extra heavy duty
These Heavy Duty Rollers are designed for heavy duty open mining applications. The heavy duty PRECISMECA / RULMECA GROUP rollers are assembled with bearing sizes 6308-6312.
Supreme
HDPE roller for mining and aggressive applications.
TOP
HDPE rollers for light to medium duty applications: a light, strong, eco-friendly solution.
PL
Anti-corrosion rollers - series PL/PLF for belt conveyors handling corrosive materials. Shaft diameter: 20 mm - PVC or steel tube with diameter from 89 to 140 mm
