The Williams Willpactor® primary impact crusher can be utilized for a variety of applications such as concrete or cement crushing, or for reducing run-of-mine quarry rock, limestone, asphalt, anode butts, and various minerals. This "New Holland"-style impact crusher design even allows for the machine to be mounted on a mobile frame by others.

Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below "Dry" crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called "grinding".

a) Primary crusher – The raw material from mines is processed first in primary crushers.. The input of such crushers is relatively wider and the output products are coarser in size. Example - Jaw crusher, Gyratory crusher. b) Secondary crusher- The crushed rocks from primary crusher are sent to secondary crusher for further size reduction.

Primary crushers are usually stationary machines, whereas secondary crushers are often mobile or semi-mobile machines that can be moved around to different locations. Additionally, primary crushers are typically operated in open-circuit mode, whereas secondary crushers are often operated in closed-circuit mode.

A gyratory crusher is a type of crusher that uses a mantle to guide the crushing process. The mantle is suspended on an eccentrically rotating shaft, which causes the mantle to gyrate. The gyratory crusher has a higher capacity than a jaw crusher. It is often used for primary crushing in the stone crushing industry.

The primary crushing stage at the top of the machine and the secondary stage at the bottom of the machine both consist of a double-roll arrangement. Due to the feed opening and design of the top stage, these types of Roll Crushers are best for handling medium sized feed material.
