Mobile crushers are mounted on a self-propelled steel platform equipped with wheels, crawlers, or pneumatic pads for movement. The platform incorporates all necessary auxiliary equipment and subsystems for crusher operation. They operate independently on the mine floor. Placed at the working face, the crusher minimizes the need for truck or front-end loader transport, with planned moves occurring between one day and one week. Installation of mobile crushing plants is advantageous under specific conditions; * A clear and undisturbed geological situation, * Straight and long benches for shiftable face conveyor installation, * Long-term mine planning for various conveyors. The benefits of fully-mobile crushers include * Elimination of truck transport * Reduced personnel requirements * Avoidance of high truck maintenance costs * Decreased mine traffic * Overall improvement in mine safety.

The Cone crusher has a smaller crushing chamber. Therefore, break the rocks by tightening them between the rotating spindles. In addition, these spindles are completely covered with a sturdy mantle and a manganese bowl liner covers the hopper. When the rocks enter between the lining of the bowl and the mantle, the rocks are tightened. The broken rock pieces fall to the next position where they break again. Then, the same process repeats until the broken pieces become small enough to pass through the narrow opening in the bottom of the conical crusher.

The distinguishing feature of the jaw crusher is that it has two jaws which are placed with an acute angle between them and the two open and close as animal jaws do. The jaws are such that one is fixed while the other is hinged, swinging relative to the immobile jaw. Jaw crushers are classified based on the way the swinging jaw is pivoted. In the Blake Jaw crusher, the swinging jaw is pivoted at the top and thus it has an ore receiving area that is fixed and an exit or discharge opening that is variable. For the Dodge Toggle Jaw crusher, on the other hand, the pivoting is at the bottom making it to have a receiving area that varies and a delivery opening that is fixed. Jaw crushers are rated on the basis of the receiving areas, which are the product of the width of the jaws and the gape. The gape is the distance at the feed opening between the jaws. For instance, a 2130 × 1680 mm jaw crusher specification means that the jaw crusher has a width of 2130 mm and a gape of 1680 mm.

Grizzly screens are typically constructed by welding steel rails, rods, or bars into grids with a specific pattern. The selection of rails can vary in size, ranging from about 7.4 kg/m to approximately 225 kg/m. These rails generally run parallel to each other along the entire length of the screening surface. The spacing between the rails typically range from 5 to 200 mm. To facilitate the smooth flow of materials, the openings are often tapered, with the top being wider than the bottom. Heavy-duty grizzly bars are commonly cast from manganese steel and feature double tapers. These grizzly screens are designed to receive large lumps of ore from sources such as railroad wagons, tipper cars, and other bulk material handling systems that discharge materials from considerable heights. As a result, they are constructed to be exceptionally robust to withstand the impact and handling of heavy materials.
