Vacuum Lid for Small Aggregate Washer

Advanced Vacuum Lid for Small Aggregate Washer

Enhance the precision and efficiency of your aggregate testing with the advanced Vacuum Lid designed specifically for the Small Automatic Aggregate Washer. This innovative lid transforms your washer into a dual-purpose instrument, serving as both an effective deairing device and a high-accuracy vacuum pycnometer. It is an indispensable tool for conducting reliable asphalt rice tests (AASHTO T 209 and ASTM D2041) and other critical specific gravity measurements, ensuring the integrity of your material analysis.

Unmatched Deairing and Pycnometer Functionality: The primary function of this vacuum lid is to efficiently remove entrapped air from aggregate samples and asphalt mixtures. Trapped air can significantly skew test results, leading to inaccurate determinations of specific gravity and void content. Our unique design capitalizes on the rotating action of the aggregate washer drum, allowing the sample to continuously tumble under vacuum. This dynamic agitation ensures maximum air extraction from all surfaces and voids within the sample, far surpassing the effectiveness of static deairing methods. When combined with a vacuum source, it creates an ideal environment for precise specific gravity determinations, crucial for quality control in asphalt pavement design and production.

Robust Construction and Smart Design: Crafted from durable, clear acrylic, the lid provides full visibility of the deairing process, allowing operators to monitor the sample and ensure complete air removal. It is meticulously fitted with a high-quality rotating vacuum seal that maintains a tight, consistent vacuum seal even while the drum is in motion. The lid also features a dedicated port for seamless connection to any standard vacuum source and robust locking tabs that securely fasten it to the aggregate washer, preventing accidental dislodgement and ensuring safe operation.

Key Features:

• Dual Functionality: Acts as both a highly efficient deairing device and a precise vacuum pycnometer.
