Now you can take on 1 POWER PER UNIT VOLUME KW/LITRE CAPACITY 2 Machine Power and Size Mills are designed to process required volumes of product, to a specified quality, during a particular time scale. This defines the ‘production capacity’ of the mill and is related to power and size of the machine. The machine must provide sufficient energy to achieve the desired grinding effect. It must also have sufficient capacity to accommodate the required flow rates of the product. The maximum production capacity (M) can be estimated on the basis of the specific energy requirement (E M) for the application and the converted diving power P- PO. M (t/h) = P - PO (KW) (KWh/t) EM where M = mass flow rate; P = power consumption; PO = idle power; E M = specific energy. For example, if in a mill a power of P – PO = 250 KW is converted and the specific energy requirement is E M = 50 KWh/t, the net production capacity is M(t/h) = 5 t/h (dry material). any job – plastic and metal coatings, inks, display, automotive, adhesives – or even a totally new application.
