Combination Crusher

Combination Crusher

The combination crusher is a new generation high efficiency crushing machine designed and researched by integrating the domestic and foreign crusher technology with the same kinds and optimizing the main technical parameters.

to determine the crushing value of road aggregates

The aggregate crushing value providesa relative measure of resistance to crushing under a gradually applied compressive load.To achieve a high quality of pavement, aggregates possessing low aggregate crushing value should be preferred. Why to test Aggregate Crushing Value? The principal mechanical properties required in road stones are: We are a professional mining machinery manufacturer, the main equipment including: jaw crusher, cone crusher and other sandstone equipment;Ball mill, flotation machine, concentrator and other beneficiation equipment; Powder Grinding Plant, rotary dryer, you can click the button to consult us.
