Introduction: The SYD-0758 rotary bottle abrasion tester is designed and manufactured in accordance with the technical and functional requirements of the T 0758-2011 "Compatibility Grade Test for Slurry Mixtures" in the industry standard JTG E20-2011 "Test Code for Asphalt and Asphalt Mixtures in Highway Engineering" of the People's Republic of China. It is suitable for completing the rotational abrasion treatment of specimens according to the standard test methods, and then calculating and determining the compatibility between specific graded aggregates and modified emulsified asphalt. Features: 1. This instrument is a floor standing, box type structure with a reasonable structure and convenient use. 2. Adopting an orthogonal double support structure mode, 8 samples can be tested simultaneously at once, with high work efficiency. 3. The proximity switch is used as a counting device for the number of rotations, ensuring accurate and reliable counting. 4. The overall structural design of this instrument is stable and can meet the requirements of simultaneous rotation and wear testing of multiple specimens. 5. This instrument is designed with a power-off automatic memory function, and the number of rotations can be accumulated or reset to start counting again from zero. 6. The specifications and dimensions of the testing instruments of this instrument comply with the requirements of T 0758 standard. Technical parameters: Motor speed: 1400r/min; Wear bottle rotation speed: 20r/min ± 0.5 r/min; Wear bottle rotation time: 180 minutes (the maximum rotation time is 480 minutes); Specification of wear tube (bottle): inner diameter 60mm ± 0.2mm, internal height 400mm ± 1mm; Maximum number of samples: 8; External dimensions: 735mm x 705mm x 1002mm (length x width x height); Working power supply: AC380V, 50Hz, Main optional accessories 1. Balance: Weigh 300g, with a sensitivity not exceeding 0.01g; 2. Oven: With forced ventilation, the temperature can be controlled at (60 ± 3) ℃; 3. Constant temperature water bath: HWY-10 low-temperature constant temperature water bath.
