The first crusher in a crushing system into which material is fed. Succeeding crushers in the system are referred to as secondary (second), tertiary (third) or quaternary (fourth) crushers. Reduction Ratio The ratio of the top size of input material to the top size of crusher discharge material. Run of Mine (ROM)
In the above example, there is enough material in the +10.0mm and +1.7mm feed size ranges to meet the required discharge product size distribution. For the +0.85mm size range only 15% is available where 20% is requested. Model Theory
crushers, the crusher will exhibit a different capacity, power required, and discharge size distribution as the speed ranges over the design limits of the machine. This study documents the measured variation in production and energy efficiency both when the crusher was ran at full
Crusher-Setting, Product-Size Gyratory and jaw crushers are always rated at certain open-side or close-side discharge settings . In order that we may select the particular curve, of a group of curves, which will most nearly represent the product of a crusher having any given discharge setting, it is important to know approximately what
A crusher is not able to directly produce a specific grain size, so the discharge always contains a wide range from fines up to a maximum size, plus oversize. The solution is a crushing circuit with an arrangement of a crusher, a subsequent screen and a conveyor to return the oversize to the crusher.
9 Particle size distribution along the long axis of the second compartment with using a VSI impact crusher 10 Comparison of fineness variation on the basis of 0.090 mm and 0.045 mm passing % along the grinding compartment length for both grinding cases
Increasing the speed of the rotor from nominal to maximum, will only increase the finer product discharge from the crusher by about 3%. But this also increase wear parts consumption and decreases the throughput of desired Size distribution of the product is affected by the following factors: • The work index of the material (Wi).
The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent. The finer the closed-side setting, the greater the proportion of fines produced. The closed-side setting of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees.
Fig.3 Scheme of breaking process in crusher [1] Mass Balance (Size distribution) According To size distribution model given by whiten (1972) the particles are represented in a discrete form of vectors [1] (f) and (p) where f = feed vector P = product vector C = Classification operator, computes the probability of breakage of each particle size.

Feed Size Distribution Feedforward Control for a Grinding. AMIT 135: Lesson 3 Particle Size Distribution Mining. The mean size of the material passing the 0.15mm screen can be estimated assuming the bottom size is 1 micron. Particle Sizes Distribution Models. There is a common need to determine the amount of material in the feed at a given
a crusher’s discharge opening, as the production continues through an on-line coarse size analysis of the crushed product (digital image analyses). Dance, A. 2001) • More attention is being paid to the impact on crushing circuit design caused by variations in ore characteristics, size distribution, moisture content, ore grade and
known traditional jaw crusher range that is designed for stationary as well as mobile applications (C80, C100, C3054, C120, C125, C140, C150, C160, C200). The second range is designed specifically to meet the needs of small to medium size mobile crushing (C96, C106, C116). All C Series crushers are designed to crush very hard rock.
The steady-state of Whiten’s cone crusher model results from the mass balance per material class size applied to a cone crusher where Q is a diagonal matrix that represents each element in the specific discharge rate. Gustafsson, T. Control oriented modeling of flow and size distribution in cone crushers. Miner. Eng. 2014, 56, 81–90
often generating undesirable size distribution in the crusher discharge. Fine Grinding and Pulverizing – 250 to 325 feet per second (75 mps to 100 mps). Speeds above 250 feet per second are reserved for applications where pulverizing and grinding of the material is desired. At these higher speeds, it is possible to produce manufactured sand and
crusher, in which the particles are broken during impact. Particle fragmentation characterization aims to quantify the size distribution of the product and establish the relationship between specific energy inputs and resultant discharge port into another collector located under the

Roller crusher. The particle size is generally controlled through the wedge between the two rollers or shim adjustment device. When the wedge is pulled up, the gap between the two rollers becomes larger, and the grain size of the discharge becomes larger. When the wedge is downward, the size of the discharge becomes smaller.

For most friable materials, the efficiency is excellent because the physics works in our favor to produce a consistent discharge particle size distribution largely independent of the particle size distribution at the feed. For roller crushers, if there is any moisture content to the product, the product will not crush, but will flatten into
