        <p>Традиционно принято определять производительность щековой дробилки, исходя из объема так называемой призмы выпадения в лимитирующей зоне. При прямолинейных очертаниях щек эта зона находится в самом низу рабочего пространства. При этом предполагается, что материал разгружается только во вре­мя отхода подвижной щеки. При сближении же щек материал дробится, а разгруз­ки не происходит.</p>

        <p>Traditionally, it is customary to determine the capacity of a jaw crusher based on the volume of the so-called dropout prism in the limiting zone. In case of straight jaw outlines, this zone is located at the very bottom of the working space. It is assumed that the material is discharged only when the movable jaw is moving away. As the jaws move closer together, the material is crushed and no discharge takes place.</p>
