The space from grinding table to classifier is divided into 24 sectors and energy balance is applied to each sector. Zhou et al. (2000) proposed a model where internal region of the mill is divided into five zones and coal is divided into five size groups. Heat balance and mass balance for coal and moisture is considered in each zone.

According to statistics, in 2021, China's annual energy consumption reached 5.24 billion tons of standard coal, of which coal resource consumption accounts for 56.0% of total energy consumption [2,3].

The energy consumption of a pulp and paper mill depends on the raw materials used, the type of pulping process and the degree and type of final products [38].Papermaking as a sophisticated process can be divided into major sub-operations, as illustrated in Figs. 1 and 2.This integrated process incorporates an integrated mill (pulp …

The mass balance equation of the raw mill process can be written as: (11) m ˙ 1 + m ˙ 4 = m ˙ 2 + m ˙ 3. Based on the general energy balance equation, which given in Eq.

The general mass balance for a quantity with a system is given by the relation: (1) Accumulation = In − Out + Generation − Consumption. The pulp consists of fibres, usually acquired from wood. The pulping process aims at separating the fibres fixed in the wood or plant matrix, this can be achieved either mechanically or chemically.

In order to express −W s in terms of energy per unit mass to maintain consistency with ΔH, the right side of the equation must be divided by the total mass flow rate of the process stream. The result is the final defined work term of the energy balance: (18)-W s = ε m ε b EI-π 30 fm f r b s M. 3.3. Overall energy balance

Mass balance calculations can use the depiction of a flowsheet in two ways. Simple calculations should superimpose the calculation cells directly over the flowsheet, as in example calc #1. More complicated calcs should use the flowsheet to define stream numbers and then perform the computations in a table, as in example calc #2. Ball Mill ...
