Hold the Line

Belting is the most expensive component of a conveying system. Superior’s Self-Aligning Idlers ensure that your conveyor belts stay on track, minimizing the chance of severe belt damage.
Concave in shape, the idler’s side guide rollers restrain the belt from running up and over the conveyor. In order to lessen the wear on the belt, the side guide rollers are made with high-grade HDPE that reduces the friction between the idler and belt.

Feed size is determined by measuring the longest one-way dimension of the material sample. Projected crusher capacities are based on a material having a work index of 12-14, with a bulk density of 100 lbs/ft3 (1.6 mt/m3). The feed grading must have less than 10% passing the crusher setting. The crusher drive assemblies are to be maintained in good working order with the ability to apply all available horsepower without drive belt slippage. Plant installation to ensure the crusher is able to operate continuously consuming the FLA rating of the motor(s) with the equipment able to accept and discharge material freely. For secondary cone crusher applications to be used in closed circuit applications consult Superior for capacity adjustments.

Built to Spin Clean

Wing pulleys live in the dirtiest spots of a conveyor circuit, where fugitive material can cause damage fast. Superior’s Chevron® Pulley takes that challenge head-on with a v-shaped design that keeps the belt centered, sheds material efficiently, and reduces vibration for longer component life.

Whether you choose the Chevron Pulley or a traditional straight-wing style, every pulley is built with thick rims, solid welds, and precise balance. The result is smooth rotation, longer belt life, and reliable performance in the harshest conditions.

Models

Chevron® Wing

Patented v-shaped wings deflect fugitive rock, resist wing bending, maintain constant belt contact, and are gentler on splices for reducing noise and maintenance.

Get the Details

3D rendering of the Superior® Wing Pulley designed for conveyor tail and bend pulley use, with open wings that help remove material from the belt and reduce buildup.

Traditional Wing

Traditional straight-wing design for general duty where material lodging and belt contact are less critical.

Get the Details

Advantages

Deflect Fugitive Material

Sheds material out and away from the pulley, preventing it from trapping between wings.

Resists Wing Bending

By design, traditional pulleys have always had wing bending issues. By design, the Chevron Pulley does not.

Longer Lasting Belts

When there’s no fugitive material to puncture belting or bent wings to cause mistracking, conveyor belts last a lot longer!

Less Noise & Vibration

Steady, continuous contact between the pulley and belt reduces noise and vibration by as much as 50 dB per pulley.

The Wing That Changed Conveying

This animation highlights the five biggest benefits that made the Chevron Pulley a breakthrough in conveyor performance.

While the clip features a capped-wing model (still available for select applications), today’s Chevron Pulley has evolved, with a full-width wearable wing and optional AR steel construction that extend life even further.
