· Centrifugal pumps have limited suction lift capabilities and limited pressure capabilities. You may want to avoid a centrifugal pump if you have a high-pressure or high-lift application. Rotary pumps, on the other hand, generally don’t offer the same operating efficiency as centrifugal pumps. However, the advantages and disadvantages may vary

A primary crusher is designed to receive run-on-mine (ROM) rocks directly from the mines. Gyratory crushers typically crush to reduce the size of aggregate to a maximum of about one-tenth of its original size. Gyratory crushers are always installed vertically orientated. A gyratory crusher’s size is classified by:

Here are the main parts typically found in a centrifugal pump: Impeller: This is the rotating component of the pump that imparts energy to the fluid. It is usually made of metal and has curved blades that accelerate the fluid. Casing: The casing is the outer covering of the pump that houses the impeller and other internal parts.
