ball mill for grinding lactose

Grinding and granulation in a vibratory ball mill - ScienceDirectIn the grinding of paracetamol, lactose and sucrose in a vibratory ball mill, it is found that an equilibrium is rapidly attained due to the agglomeration of ground particles. The existence of this agglomerative phase of comminution has been extensively reported in the literature. This study investigates prolonged vibratory ball.Comminution-amorphisation relationships during ball milling of .Aug 7, 2017 . The purpose of the study was to investigate the relationship between comminution and amorphisation of α-lactose monohydrate particles during ball milling under different milling conditions, including ball-to-powder mass ratio, milling time and ball diameter. The results revealed that at a constant ball filling.

Isomerization of Lactose in Solid-state by Mechanical Stress During .

Abstract— Isomerization during grinding of solid-state α-monohydrate, α-anhydrate and β-anhydrate of lactose was investigated. Samples were ground in an agate centrifugal ball-mill at 270 rev min−1 at room temperature (20°C). The crystallinity of ground lactose was measured by Hermans' method from the powder X-ray.
