average mill waste generation of 100 kg per air dried metric ton (ADMT) pulp, the waste generated at kraft pulp mills amounts to be 14 million metric tons globally. The majority of the waste consists of sludge from wastewater treatment, ash from biomass combustion, green liquor dregs, lime mud, and slaker grits from causticizing.

Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.

calculate the heat energy required to remove the moisture per unit weight of raw material. Heat energy required per kg raw material o= heat energy to raise temperature to 60 C + latent heat of vaporization at 20 kPa abs. = (60 - 21) x 3.8 + 0.778 x 2358 = 148.2 + 1834.5 = 1983kJ. In freeze drying the latent heat of sublimation must be supplied.

When the temperature of rendered material reaches about 65°C, enzymic activity stops and hydrolysis of triglycerides ceases. If finished tallow contains moisture and

The results show that performance improvement in the 2 to 5 percent range can be achieved by removing 5 to 15 percent of the coal moisture from the baseline value. Predicted variation of the mill exit temperature (temperature of the coal-primary air mixture leaving the mill) with coal moisture content is presented in Figure 4.

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.
