Jaw Crushers are not a shaping crusher. Because they typically produce an elongated, flat and slabby product, Jaw Crushers are usually followed by a secondary crusher, such as a cone, impactor or roll crusher, for refining and further size reduction.. These crushers come in a range of styles and sizes and are capable of handling low …
The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It …
A sectional view of the single-toggle type of jaw crusher is shown below. In one respect, the working principle and application of this machine are similar: the movable jaw has its maximum movement at the top of the crushing chamber, and minimum movement at the discharge point. The motion is, however, a more complex one than the …
The jaw crusher line is designed for the motor sizes listed in RPG and technical specifications. This means that for harder materials, the crusher will have to be operated at larger settings to avoid overload of drive and/or motor. Using oversized motors will lead to radically shorter crusher life and various mechanical problems.
A jaw crusher, like that of the Table below, is set with an open circuit (no recirculation) at 2 in. to produce 60 tons per hour (tph) of crushed limestone aggregate. (a) How much of the output will pass a 1½-in. screen (i.e., minus 1½-in. material), and (b) how much of the material—percentage and tonnage—will pass the 1½-in. screen and ...
Maximizing crusher performance and productivity requires selecting the right jaw crusher size and capacity. Learn how to determine the optimal size and capacity for your application, and discover the benefits of choosing the right equipment. Our expert guide provides valuable insights and recommendations for achieving the best possible …
4.4 Design calculations 38 4.5 Design of spring for tension bar 40 ... 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 ... Jaw crusher movement is guided by pivoting …
What are jaw crushers? A jaw crusher is a crucial component in mining and ore processing plants, performing the primary crushing of rock and mineral ore to reduce and control the size of materials for further sizing, shaping, beneficiation and processing.
The numerator is calculating the volume of one swing of a jaw, times the density of material in the chamber, times the number of cycles per minute. This should give you the mass of material crushed per minute.
Johansson at al. (2017) proposed a basic model for an industrial-scale jaw crusher, which predicted capacity and power consumption for various speeds and crusher settings. Fladvad and Onnela (2020) proposed a parameter study after investigating the influence of feed and jaw crusher parameters on aggregate quality in single-stage …

Hersam (1923) proposed a method for calculating capacities using a Dodge-type jaw crusher. The equation proposed by Hersam includes a number of constants that are only qualitatively related to the machine and material characteristics.
Capacity increases when material below the crusher setting bypasses the crusher. The energy consumption is also lower. The life of wear parts increases. A jaw crusher usually wears more manganese steel per crushed tonne than a gyratory crusher.
For more precise calculation you look at the dimension of the crusher at the closed side setting (as a volume) then multiply this by the unit of time (usually hours) then consider the density of the material to get a weight per time. Note this will be an optimistic number …
