Douglas Manufacturing Co.’s Interceptor is a self-cleaning, permanent magnetic separator designed specifically for portable plants. The Interceptor is equipped with a low-speed, high-torque hydraulic drive and automatically discharges tramp metal away from the conveyor. The magnet is compact and lightweight, the company says, and has a suspension height of up to 12 in. from its belt top cover. The magnet features crown face pulleys for vulcanized lagging and comes standard with slide tube belt take-ups.

Spring impact roll offers unique advantages

PPI‘s (Precision Pulley & Idler) spring impact roll is made of high-strength tempered steel, providing impact absorption and durability. Where unsupported belting is vulnerable to impact damage, PPI says the spring impact roll has a natural trough shape that allows for continuous belt support with no roll gaps. The spring design responds to increasing loads by flexing more, increasing the troughing angle to accommodate the load. Additionally, PPI says the spring impact roll’s heavy-duty steel mounting brackets are designed to be a bolt-in replacement for existing impact or conventional idlers, providing extra strength in demanding conditions.

Drum motor safety enhanced by design 

The motor, gear reducer and bearings of GrizzlyDrive drum motors are enclosed and protected inside the drum and designed for 80,000 hours of continuous operation before maintenance. According to VDG (Van der Graaf), the design increases safety while decreasing maintenance and operating costs. With VDG IronGrip lagging, the company says the GrizzlyDrive delivers 40 percent more traction and improved tracking while increasing lagging and belt life. The all-enclosed design and construction of the GrizzlyDrive reduces the cost of ownership, VDG adds, and provides conveyors with reliability, longevity and performance in harsh environments.

Carryback solutions simplify maintenance

The design of the DT2S and DT2H reversible cleaners reduces system downtime and labor for cleanup or service while helping to prolong the service life of other conveyor components. According to Martin Engineering, the cleaners feature a split-track blade cartridge that slides in and out on a stainless steel mandrel. They can be serviced or replaced without stopping the belt when on-site safety approvals are in place. Martin Engineering says both products significantly reduce material carryback, and they’re engineered to accommodate reversing conveyors to avoid damage to the belt or splicing.

Expedite start-up in cold conditions

PCI’s Ice-Eradicator aims to temper the effects of frozen conveyor belts. The drum-style Ice-Eradicator is installed at the head position of a conveyor and de-ices and softens the conveyor belt, encouraging start-up in freezing conditions. PCI says the technology can be adapted to any Eradicator or Deflector wing pulley to discourage problems related to ice buildup in non-drive positions. According to PCI, its tech incorporates a slip ring and heating element to heat an internal liquid solution. With a 120-volt, 15-amp power supply, PCI says the Ice-Eradicator can be energized just hours ahead of start-up, though harsher environments may require more time. When energized, PCI says the surface temperature of the pulley increases at a rate of 25 degrees an hour, which increases the belt temperature by up to 5 degrees an hour.

Keep employees safe while extending belt life 

The unique flight pattern on Martin Sprocket & Gear’s Clean Flight Wing pulley reduces wing stress during operation to prevent wing folding that causes unplanned  downtime. According to the company, the pulley’s geometry maximizes the efficiency of material removal between flights in order to prevent belt damage. The combination of thicker flights and the helix geometry reduces material carryback and extends belt life, Martin Sprocket says, delivering improved uptime and preventing maintenance employees from having to shovel out material from under conveyors.

Idler design enhances sealing protection

Luff Industries’ idlers are built with an endcap design offering strength, durability and sealing performance. The endcap encases a triple-labyrinth seal and a sealed ball bearing to ensure contaminants like dust and moisture don’t cause premature roller failure. According to Luff, it is the first OEM in North America to achieve SKF Equipped status. Through the program, SKF bearings are integrated into Luff idlers to ensure high quality.

Shut down rotating equipment before damage occurs

The RMS-G non-contact motion controller from Conveyor Components Co. uses an inductive proximity sensor and a ferrous target disk affixed to the end shaft to determine if a piece of equipment is rotating or if it lost motion. The controller, which protects various pieces of rotating equipment, incorporates surface-mount componentry, allowing the circuit board assembly to be lower in profile, lighter in weight and reliable in operation. Zero-speed control is available in a NEMA 4 weatherproof polycarbonate enclosure, with either 120 VAC, 240 VAC or 24V AC/DC input power.  The unpowered DP/DT output relay is capable of 5 amps at 120 VAC or 240 VAC.
