Our paper presents the hammer mill working process optimization problem destined for milling energetic biomass (MiscanthusGiganteus and Salix Viminalis). For the study, functional and constructive parameters of the hammer mill were taken into consideration in order to reduce the specific energy consumption. The energy consumption dependency on the mill rotor spinning frequency and on the sieve ...

Raw Mill Optimization Module The Raw Mill Optimization option controls both the temperature, the feed rate to the mill and the separator speed in order to achieve the required throughput for kiln. Where starting the mill requires dampers to be moved, to change gas flow paths, the module will also respond to these effects to keep the system stable.

Raw Sugar What is raw sugar? Raw sugar is not exactly 'raw', as sugar cane and sugar beet must be processed to extract their sugar content. Any sugar that has been through this first cycle of crystallisation, at a sugar mill, is defined as partially purified sucrose also known as raw sugar. The word 'partially' is important here.
