For use in trail surfacing, the material should be composed of irregular angular particles that interlock and bind into a firm matrix. The rock particles should range in size from dust to 3/8 inch. Gravel and crusher fines differ from one another in that gravel is screened to remove the fines which contain the natural binders/cements.
Too large of an angle causes boiling in the crushing chamber. This is where the jaw plates cannot grip onto the rock, and it keeps slipping up and down, avoiding being crushed. The nip angle gets flatter as the machine is set tighter. The settings on a jaw crusher are designed to produce material ideal for secondary crushing.
Crushing helps to reduce the size of mined material, making it easier to process and transport. Rock crushers come in three main types: primary, secondary, …
cone crusher. Cone crushers, also known as conical crushers, break rock between an eccentric rotating head and a bowl.The rotating head is covered by a wear-resistant mantle.

One of the benefits of using an impact crusher is that it can produce a very fine rock powder. This can be helpful in certain applications, such as in manufacturing or construction. Another benefit is that an impact crusher can handle a wide variety of rock types, including harder materials that might cause problems for other types of crushers.
Crusher fines that result from hard rock feature rough, fractured edges. When packed tightly on the ground, the fines lock into one another, creating a firm, stable surface for walking and driving. If compacted tightly enough and well maintained, it can be smooth for wheelchairs and walkers and act as an alternative to different types of pavers .
