Pulley cleaner heaters are installed on the back face of conveyor pulleys to prevent the buildup of tar sand and frozen material. In winter conditions, tar sand can accumulate on pulley surfaces, causing belt misalignment, excessive wear, or even belt failure. The heaters soften or melt these deposits so the conveyor can operate smoothly. Control Innovations supplies new and retrofit pulley heater assemblies designed for reliable operation in harsh industrial environments.
Pulley cleaner heaters provide controlled heat to the back face of conveyor pulleys to prevent material buildup. By keeping the pulley surface clear, the system helps maintain belt tracking, reduces mechanical stress, and supports continuous conveyor operation in cold or heavy‑material environments.
Key Capabilities
Control Innovations pulley heater systems typically support:
- Heating elements rated for 480 V or 600 V operation
- Fused circuit‑protected control boxes wired for three‑phase systems
- Retrofit of existing heater assemblies or fabrication of new units
- Hard‑pipe or flexible‑conduit element mounting options
- Integration with existing conveyor controls or standalone operation
This ensures dependable heating performance across a wide range of conveyor applications.
Heater Assembly Construction
Pulley cleaner heater assemblies generally include:
- Heating elements mounted to pipe assemblies
- Hard pipe stubs for fixed installations
- Optional flexible conduit connections for easier mounting and alignment
- High‑temperature wiring and termination hardware
- Brackets or supports for secure attachment behind the pulley
This provides a rugged, field‑serviceable heating solution.
Control Panel & Protection
The heater control panel typically includes:
- Fused circuit protection for each heater circuit
- Three‑phase wiring for high‑voltage heater loads
- Power distribution and overcurrent protection
- Terminal blocks for field wiring
- Enclosures suitable for industrial or outdoor environments
This ensures safe operation and straightforward maintenance.
Applications
Pulley cleaner heaters are commonly used in:
- Tar sand and oil sands conveyors
- Mining and aggregate conveyors
- Cold‑weather material‑handling systems
- High‑build‑up conveyor locations
- Retrofit upgrades for existing pulley heating systems
They provide a reliable method for preventing material accumulation and maintaining conveyor performance in harsh conditions.
