Pennsylvania Crusher offers three models of single-roll crushers: the Hercules, the Atlas and the Type K. All have a roll assembly consisting of a roll shaft and a fabricated roll shell with integral fixed teeth, which operates against a breaker plate. This produces three different methods of reduction: impact, shear and compression. Applications for these models include petroleum coke, gypsum, coal with rock, aggregate, limestone, chemicals, phosphate rock, shale and many other minerals. These are crushed at low speeds and therefore tend to facture along natural cleavage lines, resulting in minimal fines.
