High-speed lignin fiber disperser (20,000–30,000 r/min) that breaks up granular fibers before oil absorption tests of asphalt pavement fibers.
Overview
This machine disperses granular lignin fibers used in asphalt pavements, and is the sample-preparation accessory for oil-absorption-rate tests specified in JT/T 533-2020 "Fibers for Asphalt Pavement". A high-speed four-blade head runs at 2000030000 r/min to break up clumped granular lignin fibers into a uniformly dispersed state before oil-absorption-rate and ash-content tests. The grinding chamber is stainless steel with a flip-top lid and bayonet clamp; the control box has a timer knob and start/stop buttons. It is simple to operate, disperses quickly, and is compact and portable.
Applications

• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
Features
• Robust construction suitable for both laboratory and field use
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the Lignin Fiber Disperser comply with?
A1: The Lignin Fiber Disperser is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the Lignin Fiber Disperser be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
