4. * Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size is 1/2 inch.

The advantages of this method are the simplicity of design and assembly, easy disassembly, productivity and in the end – cost. 2. THE SCREW JOINT A screw is exposed to tensile load, to torsion and sometimes also to a shear load. The stress in the screw when the screw has been tightened to the design extent is known as the pre-stress.

As with reliability, rolled threads provide increased part strength. Parts that are rolled have a root hardness that can be as much as 20% to 30% greater than those that are cut. Tensile strength can be as much as 10% greater. Shear strength is also increased because shear failures must occur across the great rather than with the grain.
