wemco m power consumption

Minerals 2015 OPEN ACCESS minerals - MDPI

2015-3-30  The rate of air flow and power consumption of Wemco machines depend on the flow structure and the hydrodynamics within the pulp volume. For a given machine, rate of airflow depends on the rotor speed (RPM) among other operating conditions such as rotor blades and disperser design. Instantaneous airflow rate in a Wemco machine is not known
