The maximum feed size for a jaw crusher should be about 85% of the gape. Source: Arthur Taggart; The combination of a jaw crusher and a scalping grizzly will have 15% more capacity than a stand-alone jaw crusher. Source: Ron Casson; As a rule, scalping grizzlies are rarely used anymore for (large) primary crushers.

For this reason the maximum size of material to be fed to a dual roll crusher is critical. The maximum allowable feed size is the sum of the stage of reduction capability and the product setting. If the maximum feed size is exceeded, unsatisfactory results likely to occur are as follows: 1. Retarded production 2. Excessive roll shell wear 3.
