For bladder accumulators, this ratio is 4:1. For piston accumulators the ratio is higher at 6:1. If exceeded, this may cause rupture to the cylinder piston or the bladder Minimum Pressure To prevent damage to the accumulator, we need to keep the minimum pressure at or above the charge pressure.
The feed material (cement clinker, slag or other cement raw material) is supplied to the roller press through inlet and here it is directed down between the two rollers which rotate against each other. At the same time, the movable roller is forced towards stationary roller at a fixed hydraulic pressure.

A bladder accumulator should not be used when pre-charge pressure is below 25% of the maximum pressure. This avoids compressing the bladder so tightly that it rubs on itself, which can create holes in it. The design and physical construction of bladder and diaphragm accumulators limits their maximum operating pressure ratios.
