CONTI SYNCHRORIB Belts
One side of the belt is composed of a timing belt (SYNCHRO), while the other side features a poly-V-belt (RIB). The timing belt ensures precise, synchronous movement, whereas the ribbed side permits minor slippage.
These belts were specifically designed for mill table roller drives. This is because double-sided timing belts often suffered damage due to overloading and shocks.

- Low in PAHs – category 2 according to AfPS-GS-2014-01-PAK (for CXP and CXA design)
Profile and Dimensions of Combined Belts
The toothed side of the belts can have either an HTD or STD profile. The type of tension member used depends on the power to be transmitted. They are available with a glass cord tension member (STANDARD and CXP), or with an aramid tension member (CXA).
The ribbed side of the belt has a PK profile with a rib spacing of 3.56 mm. These are quite unique belts, produced in only a few specific lengths and widths, which are determined by the number of ribs.
Available Profiles and Length Ranges
| Profile | Belt Length (mm) |
|---|---|
| HTD 8M | 1760–2400 |
| STD S8M | 1552–2800 |
| HTD 14M * | 1778 |
* This profile is not included in the ContiTech product range for the CONTI SYNCHRORIB belt series. However, we can offer a product from another manufacturer.
CONTI SYNCHRORIB Belts Construction
The construction process of the belt begins by grinding a single-sided timing belt of specified dimensions until it is just above the tensile fibers.
Subsequently, a rubber backing is vulcanized onto this ground base. After the vulcanization process, the required number of PK profile grooves are ground into the rubber back.

- Synthetic rubber teeth
- Glass cord tension member for STANDARD or CXP (aramid tension member for CXA)
- Synthetic rubber ribs
Modern Mills and Power Transmission
The milling industry boasts centuries of history, with technology that is constantly evolving. While traditional mills utilized stones rotating against each other to crush grain, modern mills grind the grain into flour using a mill table.
Mill tables operate on the principle of rollers rotating against each other at varying speeds. The grain is gradually refined and ultimately crushed to the desired coarseness. The surface of the rollers can be either smooth or grooved, depending on the fineness required for the material being ground. The deeper the grooves, the coarser the resulting flour or scrap. Mill tables are more efficient than traditional grinding stones and can produce flour of a higher quality.
The rollers of the mill table are typically driven by an electric motor, which transmits power to the rollers via belts. The type of belt used depends on the specific characteristics of the machine. Some milling machines also employ gears, which are more robust and durable than belts, but also more expensive and noisier.
CONTI SYNCHRORIB combined belts are a reliable and economical choice for driving the grinding mill tables in a wide variety of mills.
