Home > Rotary Dryer Drums
In addition to the features offered by the BG Europa dryer drum shell, a complete rotary dryer drum installation retains our focus on ensuring long life expectancy and low operational costs by offering the following:
- Heavy duty chassis in stationary, relocatable or mobile designs. Mobile chassis feature fifth wheel coupling and airbag suspension
- Pivoting trunnion roller support stools enable tracking by skewing the trunnion roller tangentially to the trunnion ring. This design ensures that the trunnion rollers have full face contact with the trunnion ring at all times, thus ensuring even distribution of forces over the roller and trunnion ring for minimum wear. This design is particularly beneficial when using nylon rollers which can be damaged by point loading.
- Heavy duty trunnion roller assemblies incorporate internal taper roller bearings to lock all thrust forces into the roller assembly. This design significantly reduces forces on the trunnion shaft and negates the need for keyways which are traditionally a source of weakness.
- Trunnion rollers manufactured from EN8 steel with flame hardened wearing faces for maximum life. Alternatively rollers manufactured from genuine Devol nylon to reduce noise emissions.
Choice of drive arrangements:
- The under-slung chain drive reduces the forces on the trunnion paths improving the life expectancy of the trunnion rings when compared to that offered by wrap over drive systems. Direct coupled gearmotor units give compact and efficient motive power. Alternatively piggy back mounted gear units allow drum speed to be altered without the use of an inverter. All drive sprockets are manufactured from EN8 steel and flame hardened for maximum life. A spring tensioned idler support protects the chain and drive unit from shock loads and ensures operational life is maximised
- Trunnion roller drives incorporate a hollow shaft torque arm gearbox mounted directly on each trunnion shaft. Belt driven from an electric motor the design allows the trunnion roller to pivot for drum tracking whilst providing full face contact with the trunnion ring, ensuring optimum drive and minimal wear.
All dryer drums are manufactured in our UK workshop to high standards of workmanship. If required we also offer a full project management and installation service from our own fully qualified engineers backed up with our fully equipped site vehicles.
