Pneumatic Cylinders for Asphalt, Concrete and Recycling Plants

Pneumatic cylinders are used throughout asphalt plants, concrete batching plants and recycling facilities to control the movement of aggregate, recycled materials, additives and finished products.

Cylinder Warehouse supports plant engineers, maintenance teams and equipment manufacturers with exact replacement cylinders and clearly identified alternative options across multiple established pneumatic brands.

Roladex Industrial Ltd, the company behind Cylinder Warehouse, is a member of the Materials Handling Engineers Association (MHEA). This supports our understanding of bulk handling equipment, demanding plant environments and the importance of reducing machinery downtime.

Pneumatic cylinders in asphalt plants

Asphalt production equipment can use pneumatic cylinders on:

• Cold feed bin gates
• Aggregate weigh hoppers
• Hot aggregate handling systems
• Filler and additive equipment
• Mixer discharge doors
• Bypass chutes and diverters
• Bag filter and dust handling equipment
• Plant access doors and guards

Temperature, dust, vibration and material build-up must be considered when selecting cylinders and mounting positions within an asphalt plant.

Pneumatic cylinders in concrete batching plants

Concrete batching plants use pneumatic cylinders to operate:

• Aggregate bin discharge gates
• Cement and powder weigh hoppers
• Mixer discharge doors
• Admixture and additive systems
• Skip and material handling mechanisms
• Diverters and loading chutes
• Dust extraction equipment

Reliable gate movement is particularly important where product build-up, moisture or irregular loading can increase the force required from the cylinder.

Pneumatic cylinders in recycling plants

Recycling machinery uses pneumatic cylinders across sorting, separation, processing and materials handling operations.

Typical applications include:

• Conveyor diverters
• Material sorting gates
• Reject mechanisms
• Chute doors
• Bag opening and handling machinery
• Screening and separation equipment
• Baling and packaging support systems
• Automated guards and access doors

Operating conditions

Cylinders installed in these plants may be exposed to:

• Abrasive dust
• Moisture
• High or changing temperatures
• Mechanical vibration
• Material contamination
• Frequent cycling
• Restricted maintenance access

Depending on the application, selection may require additional rod protection, corrosion-resistant materials, suitable sealing arrangements or external load guidance.

Cylinder types used

ISO 15552 pneumatic cylinders are widely used for robust gate, chute and machine movements.

Guided cylinders can support mechanisms that create side loads or require controlled alignment.

Larger gates and hoppers may require cylinders from the large-bore pneumatic cylinder ranges.

Replacement and alternative cylinder supply

Provide the manufacturer, part number, bore, stroke, mounting arrangement and photographs of the existing cylinder and installation.

Where the original cylinder is obsolete or unavailable, Cylinder Warehouse can review suitable alternatives from other established pneumatic manufacturers. Any alternative will be identified clearly and relevant differences will be explained before supply.
