One of the most important characteristics of a primary crusher is its capacity for accepting feed material without bridging. A large primary crusher is, naturally, more expensive than a smaller one. Therefore, the investment cost calculations for primary crushers are compared together against the total costs of primary stages, including quarry ...
May 01, 1994 By using the data of E.A. Hersam and F.C. Bonds equation for energy consumption in comminution, a method was developed to analyze the performance of industrial jaw crushers. The study showed that industrial jaw crushers are generally operated below capacity. The study also showed that industrial jaw crushers generally have sufficient installed power to operate at full capacity. The

Apr 03, 2015 Impact crushers are often used with materials, which are soft or which are easily cleaving from the surface. The crusher consists of a fast spinning rotor and beaters attached to the rotor. Feed is entering to the crusher from the top and crushing starts immediately when the feed is impacted with beaters towards the crushers inner surface.
13.3.1.1 Primary Crusher. Primary crushers are heavy-duty rugged machines used to crush ROM ore of () 1.5 m size. These large-sized ores are reduced at the primary crushing stage for an output product dimension of 1020 cm. The common primary crushers are of jaw and gyratory types.
Cone Crushers. A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point.
