Micro-deval abrasion testing machine is used to test the abrasion resistance of stones, aggregate, thus to evaluate the quality of aggregates.This machine is composed of drum, sealing cover, bracket, gearbox, motor, controller, it's kind of common aggregate test equipment.The machine consists of a steel frame suitable to house four 200 mm dia.x 154 mm length cylinders (EN 1097-1) .
1.The steel ball passes through two parallel bars of spaced 9.5mm, Or 10pcs used balls as a group, and balance the mass,the mass must more than 34g. 2.Quickly check the ball diameter.Power is about 1KW. Cylinder speed 100±5 tr/min. After testing,automatic interruption of engine operation. 3.It applies European/French standards.
Main structure
They are mounted on two horizontal axes.Each cylinder can be tested one test.
There should be no bulge in the cylinder caused by welding or fixing
Close the cylinder with an 8 mm thick flat cover.The cylinder is closed by 8mm thick flat cover.Secure seal through seams on flat cover
The abrasive consists of stainless steel round balls with a diameter of 10 ± 0.5mm
Make the steel ball pass through two parallel bars with a spacing of 9.5mm, or weigh the mass of 10 used balls as a group, and the mass can not be less than 34g, so as to quickly check the diameter of the ball.
An electric motor (about 1kW) must ensure that the cylinder rotates at a uniform speed of 100tr / min ± 5 TR / min. One can automatically interrupt the engine operation at the end of the test.
