reduction in size may be expressed as reduction ratio. The reduction ratio is the ratio of crusher feed size to product size. The sizes are usually defined as the 80% passing size of the cumulative size distribution. For jaw crusher, the ratio can be estimated by the gape. CHAPTER 14.

Calculation of reduction ratio in crushing [image: (135-5-3)] Crushing Equipment The selection of the right crushing equipment is influenced by many factors some of which are upstream of the crushing plant (e.g. blasting pattern and mining method) and others which are downstream of the crushing plant (e.g. mill and grinding circuit selection).
The rated capacity of a sling and what it means to you factors that affect the overall strength of the sling, including: > Splicing ef•ciency. > Design factor (5 is standard). > Number of parts of rope in the sling. > Type of hitch (straight pull, choker hitch or basket hitch). > Diameter around which the body of the sling is bent (D/d ratio).

Mechanical Reduction Methods. There are four basic ways to reduce a material - by impact, attrition, shear or compression- and most crushers employ a combination of all these crushing methods. Compression. As the name implies, crushing by compression is done between two surfaces.
We know from our examination of the crushing characteristics of these types that, for equal reduction ratios, the volume-reduction-ratio in the standard gyratory is considerably higher than it is in the fine reduction crusher. Therefore, if minimum production of fines is desirable, it is logical that the heavy end of the 7:1 reduction should be ...
• Check the crushing reduction ratio 7. Check the wear profile of the liners: a distorted wear profile may decrease capacity, increase the liner wear rate and increase the crushing force. Example of abnormal wear. Cupping has occurred. Example of normal wear. Obtained with correct feed arrangements, feed gradation and parameters for the cavity.
Feb 25, 2015· Roll Crusher • The reduction ratio and efficiency of roll crusher is very low. • The main advantage associated with roll crushers is small proportion of fines produced and more uniform size of product crushed, than the other crushers. • Low capacity • Low reduction ratio = F/P • Sensitive to top size 2/25/2015 6:58:05 AM 38 39.
8:1 maximum reduction ratio for compression crushing, this is normally used as a primary crusher. Jaws perform well in many materials. Yields low wear cost per ton in hard abrasive deposits, minimal fines but produces little finished (under 1") product which places more load …
cone crushers are an excellent choice in secondary, tertiary, quaternary and pebble-crushing applications. They are equipped with the hydraulic Hydroset™ system, which provides safety and setting-adjustment functions. The Automatic Setting Regulation control system (ASRi™) enables real-time performance management, equaling maximized crusher performance and productivity.
