A crusher can be considered as primary, secondary or fine crusher depending on the size reduction factor. a) Primary crusher – The raw material from mines is processed first in primary crushers. The input of these crushers is relatively wider and the output products are coarser in size. Example - Jaw crusher, Gyratory crusher, Impact Crushers ...

Jaw Crushers | McLanahan

Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32" from jaw die to jaw die at the top opening or gape opening and 54" across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.

The undersize is scalped before feeding to the jaw crusher. Assuming the maximum feed rate is maintained at 30 t/h and the shapes of feed and product are the same and the crusher set is 10 cm, estimate the size of jaw crusher required and the production rate. Solution. The first exercise is to determine Q RC from equation Q RC = Q R /K. Step 1

TECHNICAL NOTES 5 CRUSHERS

0.5 for both standard and short-head crushers and n2 is approximately 2.5 for short-head and 4.5 for standard crushers. The parameters in the classification and breakage functions are obviously specific to the type and size of crusher. Unfortunately not many studies have been done to establish their values under a range of actual operating ...


Selecting a crusher can be a two-part process. First, consider your application parameters, and then conduct crusher tests on your material. Some parameters about your application to consider are: material characteristics, your final product specification, and how you want to impact the downstream process.


5.1. A primary gyratory crusher was required to crush iron ore at the rate of 3000 t/h. The largest size of the run-of-mine ore was 1000 mm. The required product size was less than 162 mm. Manufacturer's data indicated that the nearest size of gyratory crusher would be 1370 mm × 1880 mm with a cone angle of 18°.


In this study, design parameters are selected to determine the size of the rotor perpendicular plate hole. It is aimed to draw the hole size of the crusher rotor perpendicular plate that can minimize accumulation of the fuel inside the crusher cell by analyzing the fuel's flow pattern according to the design parameters through flow analysis.


Jaw crushers find a wide application for brittle materials. For example, they are used for comminution of porous copper cake. A Fritsch jaw crusher with maximal feed size 95 mm, final fineness (depends on gap setting) 0.3–15 mm, and maximal continuous throughput 250 Kg/h is shown in Fig. 2.8.


Now, enter the values appropriately and accordingly for the parameters as required by the Gape Size (G) is 20 and Set Size (S) is 10. Finally, Click on Calculate As you can see from the screenshot above, Nickzom Calculator – The Calculator Encyclopedia solves for the crusher reduction ratio and presents the formula, workings and steps too.
