12%The result revealed that the energy required by a ball mill, high-pressure homogenizer and twin screw extruder were 232.5, 43.3, and 5 kWh/kg of biomass, respectively . Kim et al. showed that a large amount of energy was needed by the planetary ball mill for grinding rice straw compared to the attrition mill.
Nanocomposite materials of the Fe-Cu system with/without small addition of carbon nanotubes have been synthesized by mechanochemical activation of elemental Fe and Cu powders in a high-energy planetary ball mill and have been examined by the X-ray diffraction method, SEM and the thermopower methods; the tensile strength of the materials obtained has been estimated.
Pipe ball mills have a drum length longer than three drum diameters. Pic. 2. Cylindrical balls mill. A cylindrical ball mill used for grinding the coarse material. This mill should have a short length because the balls distributed uniformly over the entire length of the mill and during rotation obtained the same pulse. The drum diameter of the ...

The entrainment of fine particles in underflow of a grinding-classification hydrocyclone can cause ore overgrinding, which will lead to reductions in both metal recovery and ball mill throughput. To address this problem, this paper proposed a W-shaped hydrocyclone that can effectively reduce underflow fine particle entrainment. Experimental tests and numerical simulations were employed to ...

In order to determine the partition coefficients of sugars in water-IL solutions, mixtures of glucose (0.033 g) and xylose (0.021 g) were added to [C 2 mim]Cl or [C 4 mim]Cl aqueous solutions (ca 43% H 2 O, sugar concentrations are equivalent to 5 wt% switchgrass loading). To mimic acid hydrolysis conditions, 70 uL of 4 M HCl was added to the mixture.
