Machine has been developed for testing the resistance to abrasion/wear from studded tires.
Test is being performed on natural stones and aggregates between 11,2 mm and 16 mm.
Test consists of rotating aggregates in drum with steel abrasive balls and water.
The machine consists of an electronic control unit and a rolled stainless steel drum having an inside diameter of 206,5mm, internal length 335mm and thickness of 6mm. The drum is rotated at a speed of 90±3 r.p.m. 3 wings are installed inside of the drum to allow balls and aggregates to be mixed properly.
The abrasion loss rate of aggregates is calculated after specified number of revolutions stated in the related standard.
Power: 220V, 50–60 Hz, 1 ph
Weight: 95 kg.
Nordic Wear Device
While aggregates are used during road construction, it is tried to determine how durable they are against abrasion. Nordiç wear device is used to determine the aggregate wear level. Since the studded tires on the aggregates can cause wear problems, naturally the wear level of the aggregates must also be determined. It is tried to be simulated in the laboratory environment against the abrasion effect of studded tires. While testing, it is tested on both natural and artificial aggregates. In this way, after the test, the wear level of the studded tires is measured and the resistance is revealed.
Nordic Wear Device Features
Studded tires can cause wear problems on aggregates. For this reason, the wearing effect of studded rubber on the aggregate is tried to be determined by experiment. By using the Nordic abrasion device, the test is started to be applied on both artificial and natural aggregates in the range of 11.2 MM to 16 MM. While the weight capacity of the device is 95 KG, when we start to examine how the power level is, it reveals a working performance of 220 V. It also has the ability to perform wear detection operations at 50-60 Hz.
How to Use Nordic Wear Device?
It is a device that is 335 MM long, while the drum is set at 206.5 MM. When placing inside the drum, wear loss is calculated after turning to a specified standard. As a result of the calculations, a quick determination is made regarding how much wear loss is.
