Proctor Test. A particular soil needs to have an ideal (or optimum) amount of moisture to achieve maximum density. This is important not only for durability, but will save money because less compaction effort is needed to achieve the desired results. Proctor Test (ASTM D1557-91) The Proctor, or Modified Proctor Test, determines the maximum

Impact breaking is a kind of crushing machine which uses impact energy to crush materials. When the material enters the action area of the plate hammer, it will be broken by the high-speed impact of the plate hammer, and it will be thrown to the impact device installed above the rotor to be broken again, and then it will bounce back from the impact lining plate to the action area of the plate
