The material and its characteristics, e.g., its hardness, density, shape and condition, will affect the type of crusher that needs to be used. Knowing the material characteristics as well as the advantages and limitations of the different crusher types will help to determine the best primary crusher for a given application.
To determine the capacity of jaw and gyratory crushers, Broman [10] divided the crusher chamber into different sections and determined the volume of each section in terms of the angle that the moving jaw subtended with the vertical. Broman suggested that the capacity per stroke crushed in each section would be a function of the top surface …

Additionally, jaw crusher feed should be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed-side setting. Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor.
To determine the capacity of jaw and gyratory crushers, Broman [10] divided the crusher chamber into different sections and determined the volume of each section in terms of …
The capacity of the crusher is determined by its size. The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the …
There are two critical factors influencing choice of crushing techniques and equipment. Hardness of the rock and abrasiveness. Hardness of the rock is typically measured using the Mohs scale, where talc is rated as 1 (softest) and diamond as 10 (hardest). This scale helps determine what type of rock crusher is needed for the job.
You can use the following equation to calculate the efficiency of a jaw crusher: Efficiency = (crushed material/feed material) x 100. Additionally, factors such as the particle shape and size ...
The equipment operates at a capacity of 1.2 × 10 4 kg/h consuming a power of 10 hp. If the requirements of the process demand a finer size of the product (0.4 cm of median equivalent diameter) decreasing the capacity to 1.0 × 10 4 kg/h, determine the theoretical power consumption under the new conditions using Rittingers's law, Kick's law ...
To calculate the processing capacity of a mill, you will need to know the following information: 1.The width of the mill: This is the distance between the two edges of the mill where the material ...

The capacity of the crusher is determined by its size. The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers
Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are ...
Estimate Jaw Crusher Capacity. jaw crusher production capacity. Example capacity calculation of a 10″ x 20″ (250 mm x 500 mm): Pp = 2800 (2.8 SG) e = 0.2 (halfway between dolomite and sandstone) A = 250/1000 x 500/1000. Wj = 0.5. Nj = 225. = 2800 x 0.25 x 0.5 x 0.5 x 225 x (1-0.2)/60 = …
size a mill. You must know the required annual capacity, whether batch or continuous operation will be required, which upstream and downstream processes will be needed for the mill, and the properties (such as size and shape) of the finished product. Fully characterizing the feed material is essential to identifying the right mill for the job.
1. Identify The Purpose Of The Crusher. The first step in selecting a primary crusher takes place at a high level. It's necessary to identify the purpose the crusher will be used for. This purpose is a given that precedes the entire decision-making process. Sometimes, a measure of guidance or experience is needed.
The capture of a crushed piece occurs due to the stop located on the roll (see Fig. 1 ); in this case, the condition for formation of a complex stress state in the crushed piece is observed, and the energy consumption is reduced by 39–40% [ 9 ]. Fig. 1. Schematics of the crusher with stops on a roll. Full size image.
To calculate the capacity of a roll crusher, you can use the following formula: Capacity = (2.5 * R * L * S) / (V * T * H) Where: R is the roll diameter. L is the length of the roll. S is …
The Crusher throw is defined as the distance in the direction of compression the moving crushing surfaces/plates travel from OSS to CSS. Throw = OSS – CSS. OSS and CSS will define a crusher's performance. The throw of the crusher is the distance that moving jaw moves in going from OSS to CSS. The capacity is a function …
The double rotor crusher has separate drive motors for each shaft. The weight of the replacable impact hammers is in the range of 20 to 200 kg each, depending upon the crusher size. The chemical composition of the hammer steel is: c = 1.0- 1.4 %. Si = 0.4- 1.0 %. Mn = 12.0-14.0 %. p = 0.06%.

A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates. For example, if the maximum feed size is 29"x49", the crusher gape would be 32" and the width would be 54".
Size Reduction) A crusher is a machine designed to reduce the size of large rocks to smaller rocks, gravel, sand, or rock dust; this is essential for efficient transport of the product via conveyors etc. Crushing is the first of many stages that lead to separation of the mineral(s) from the waste (gangue) material.Waste material can be discarded or …
Volume is the amount of space that an object or substance occupies. Generally, the volume of a container is understood as its capacity — not the amount of space the container itself displaces. Cubic meter (m 3) is an SI unit for volume.. However, the term volume may also refer to many other things, such as. the degree of loudness or …
