VSI and GS series crushers are characterized by a unique closed-rotor design providing a higher reduction ratio with lower wear cost. The GS series crusher's bearing seat uses a thin oil lubrication system. Its highest rotor speed is clocked at 82m/s, greatly improving the capacity of the equipment and processing efficiency.
Impact crushers provide better grain-size distribution of RA for road construction purposes, and they are less sensitive to material that cannot be crushed, such as steel reinforcement. Generally, jaw and impact crushers exhibit a large reduction factor, defined as the ratio of the particle size of the input to that of the output material.
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.

Apr 16, 2021 A cone crusher in a secondary crushing application will typically work with a 35:1 to 5:1 reduction ratio Tertiary cone crusher configurations typically work with a reduction ratio of 25:1 to 4:1 The reduction ratio is defined as the ratio of the feed size for which 80 per cent will pass (F80), divided by the product size for which ...
Automatic setting regulation as applied to cone crushers can increase the average power drawn and maximize power rate along with reduction ratio. The phenomena can be studied with the pendulum impact test apparatus. Crusher productivity in quantities of a fixed size distribution is a function of power drawn as opposed to physical machine size.
Types of crushers as stone passes through a crusher the 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.
5.1.2 Impact crushers Breakage is achieved by impact using either hammer action on the individual particles or by sudden impact from a high velocity trajectory.
