Tensile strength is the maximum tension-applied load the fastener can support prior to fracture. The tensile load a fastener can withstand is determined by the formula P = St x As. • P= Tensile load– a direct measurement of clamp load (lbs., N) • St= Tensile strength– a generic measurement of the material's strength (psi, MPa).
The hydraulic control system can monitor the crushing load inside the crusher, recording production data and performance automatically, offers the operation curve and improves the information recording capability. Determining the liner wear by making the calibration and reminds users to replace the liners, so as not to damage the machine.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
