The product of a jaw crusher will have a size distribution such that the -80% fraction size (d80) is slightly less than the open-side setting of the crusher. For example, if the open- side setting is 6 inches, the d80 product size will be 5¾ inches.
Oleg D. Neikov, in Handbook of Non-Ferrous Metal Powders, 2009 Crushers. Crushers are widely used as a primary stage to produce the particulate product finer than about 50–100 mm in size. They are classified as jaw, gyratory and cone crushers based on compression, cutter mill based on shear and hammer crusher based on impact.

The vertical mill is more complex but its installation is more compact. The relative 'installed' capital costs tend to be site specific. Historically the installed cost has tended to be slightly higher for the vertical mill. 2.10.4 Particle Size Distribution. PSD has an impact on workability and rate of strength gain.
In these cases, hammer mills are a key component to operational success, helping to continuously reduce particle size and provide a reliable source of recycle. Particle Size Distribution: Often times, in order to achieve the desired end product characteristics, a range in particle size distribution is desirable.
Quick-Change Milling-Machine Vise Jaws. Significantly cut down on jaw changeover time— this two-part system lets you swap out jaws in less than 30 seconds. Mount the jaw plates to the vise and slide the dovetailed jaw stock in and out of the plates.
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 can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1.

Fig 1 Methods for size reduction of materials The reduction of size of the material when it pass through a crusher is expressed as reduction ratio. The reduction ratio is the ratio of the crusher feed size to product size. The sizes are usually defined as the 80 % passing size of the cumulative size distribution. Types of crushers

The product size distribution is obtained as perform of the crusher's rotor radius and angular velocity, the feed rate and therefore the feed size distribution. The model is based on the quality matrix formulation that features classification and breakage matrices. It are often applied to each hammer and vertical-axis impact crushers

The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. Thus far we have described machines which do a portion of their work by impact, but the only machine described in which this action plays an important role was the sledging roll type and particularly the Edison roll crusher …
is the size in microns that splits the distribution with half above and half below this diameter. The Dv50 (or Dv0.5) is the median for a volume distribution, Dn50 is used for number distributions, and Ds50 is used for surface distributions.

The size modulus is a measure of how coarse the size distribution is, and the distribution modulus is a measure of how broad the size distribution is. Size modulus for a size distribution can be determined from a graph by extrapolating the straight-line portion up to passing and finding the corresponding size value. The distribution ...
Size-reduction equipment can range from very large and rugged jaw crushers, capable of reducing boulders to sand, to very precise cutting mills.

size distribution jaw crusher The jaw crushers are available in 8 different sizes: BB 50, BB 100, BB 200, BB 300 and the bigger models BB 250, BB 400, BB 500 and BB 600. Throughput and final fineness depend on the crusher type, selected gap width and breaking properties of the sample material.
The Azzaroni equation indicates that the correct ball size for the 2.93 m mill is 81 mm. Years of experience show that a 76 mm ball grinds the coarse particles most effectively. Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill.
