RAP Conveyor for Asphalt Recycling Plants | Specifications & Standards

Product Specifications

Technical details and manufacturing context for RAP Conveyor

Definition

The RAP Conveyor is a critical component of the Recycled Asphalt Pavement (RAP) System, responsible for moving crushed and sized reclaimed asphalt pavement material between processing stages such as storage, screening, proportioning, and feeding into the asphalt mixing plant. It ensures continuous material flow while handling the abrasive and variable nature of RAP. The conveyor typically operates as a belt conveyor where a continuous loop of belting, driven by a motorized pulley, carries RAP material along its length. The belt is supported by idlers and enclosed or covered to contain dust. Speed and capacity are controlled to match the processing rate of the RAP system. Key specifications include belt widths from 800 to 1600 mm, belt speeds from 1.0 to 3.5 m/s, and capacities from 100 to 800 t/h. Operating temperatures range from -20 to 200 °C, requiring heat-resistant belt materials such as EP400/3 per ISO 15236-1. The frame is typically made of carbon steel grade Q235B per GB/T 700, with thicknesses from 6 to 12 mm. Motor power ranges from 7.5 to 45 kW, with voltages from 380 to 690 V AC per IEC 60038. Ingress protection is IP54 to IP65 per IEC 60529. Overall lengths vary from 10 to 60 m, and weights from 3 to 20 t. These values are reference ranges; actual specifications must be confirmed with the manufacturer for specific applications. The conveyor is designed for abrasive RAP, with abrasion-resistant linings and heavier gauge frames. It is essential for efficient asphalt recycling, ensuring consistent feed to the mixing plant. Proper selection requires consideration of plant layout, material characteristics, and production rates. Verification of standards and performance is necessary before procurement.

Working Principle

The RAP Conveyor operates as a belt conveyor. A motorized pulley drives a continuous loop of belting, which carries RAP material along its length. The belt is supported by idlers to maintain trough shape and reduce sag. The conveyor is typically enclosed or covered to contain dust and protect the material from weather. Speed and capacity are controlled via variable frequency drives or gearboxes to match the processing rate of the RAP system. The belt material is heat-resistant to handle RAP temperatures up to 200 °C. The frame is constructed from carbon steel with abrasion-resistant lining to withstand the abrasive nature of RAP. The conveyor ensures continuous material flow between processing stages, such as from storage to screening or from proportioning to the mixing plant. Proper tensioning and tracking are critical to prevent belt misalignment and premature wear. The system may include safety features like emergency stops and belt alignment switches.

Frequently Asked Questions

What is the typical belt width range for a RAP conveyor?

According to the directory, the belt width ranges from 800 to 1600 mm. This determines the throughput capacity. The exact width should be selected based on the required capacity and the physical characteristics of the RAP material, and must be confirmed with the manufacturer for your specific application.

Can the RAP conveyor handle hot material?

Yes, the operating temperature range is -20 to 200 °C. The belt material is specified as EP400/3 per ISO 15236-1, which is heat-resistant. However, for temperatures above 200 °C, special design considerations may be needed. Always verify the temperature limits with the supplier.

What standards are relevant for the RAP conveyor?

The directory lists ISO 15236-1 for belt material, GB/T 700 for the frame steel grade (Q235B), IEC 60034 for motor power, IEC 60038 for voltage, and IEC 60529 for ingress protection. These standards serve as procurement references; compliance must be verified with the manufacturer.

How is the conveyor speed controlled?

The belt speed ranges from 1.0 to 3.5 m/s. Speed is typically controlled using variable frequency drives or gearboxes to match the processing rate of the RAP system. The appropriate speed depends on the material flow and plant requirements, and should be set based on manufacturer recommendations.
