A general rule of thumb for applying Cone Crushers is the reduction ratio A crusher with coarse style liners would typically have a 6 1 reduction ratio Thus with a 3⁄4 closed side setting the maximum feed would be 6 x 3⁄4 or inches Reduction ratios of 8 1 may be possible in certain coarse crushing applications
The feed is limited to 1 to meters in size Thus based on reduction ratio the rock size is reduced to 10 to 15 cm Typical reduction ratios are Primary crusher 3 1 to 10 1 Secondary crusher 6 1 to 8 1 Tertiary crusher 10 1 Therefore if a 3 mm crusher product is required maximum feed size to the secondary crusher would be 240 mm
For example coarse crushers have size reduction ratios of below 8 1 while fine grinders may present ratios as high as 100 1 However large reduction ratios such as those obtained when dividing relatively large solid lumps to ultra fine powders are normally attained by several stages using diverse crushing and grinding machines
