MnDOT Pavement Design Manual. crushing or gradation, provide additional rock placed in front of the reclaimer. One hundred percent crushed chip seal rock (FA -3 per MnDOT specification 3127) works well for this purpose. (Note that older HMA may be a very sandy mix and may not provide the needed rock or crushing).

Crusher - Wikipedia

single toggle jaw crusher is its kinematic design. FL's chamber design enables the TST to efficiently crush hard material via a combination of shaft eccentricity, toggle angle and chamber layout. The steep nip angle enables the units to easily crush the hardest rock at high production rates, while maintaining the necessary product size.

The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heat-treated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength. Some results for uniaxial compressive strength σ c and tensile strength σ t ...

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
