Bitumen Loss on Heating Oven with Rotating Shelf

Thermostatic oven with a rotating shelf that heats bitumen samples at 163 deg C for five hours to measure mass loss and hardening. Used in refineries, polymer modified bitumen plants and road QC labs.

Specification

Fifty-gram bitumen samples in flat-bottom dishes are placed on a shelf that rotates at 5 to 6 rpm in a uniformly heated chamber. The mass loss and penetration drop after heating indicate volatility and ageing susceptibility of the binder. A forced ventilation arrangement keeps temperature uniform across all shelf positions.

Features

• Shelf rotating at 5.5 rpm with geared motor
• PID controller with 5 hour timer
• Double wall stainless steel chamber
• Adjustable ventilation damper
• Holds six sample dishes
