Structure of synchronous gear transmission aggregate accelerated polishing machine

1、 Application: Aggregate Accelerated Grinding Machine
This instrument is suitable for simulating the polishing effect of car tires on road surfaces indoors. By accelerating the polishing of the aggregates used on the road surface, the polishing value of the aggregates can be measured to evaluate their anti polishing performance. This provides a scientific basis for selecting suitable surface aggregates to pave road sections with different friction coefficient requirements and for the rational development and utilization of stone resources. It also creates conditions for shortening the research cycle of anti-skid road surfaces and provides technical references for the development of high-quality artificial aggregates. The JM-III accelerated polishing machine is manufactured in accordance with the national industry standard JTG E42-2005 "Test Code for Aggregates in Highway Engineering" T0321-2005 technical standard, and draws on the advantages of similar foreign models. The whole machine has a compact structure, uniform and accurate sand and water sliding, and is equipped with a speed control device, making it an ideal model to replace imported similar products.
