Ball mill for eye drop emulsions

The Drop and Bubble Micromanipulator is a special instrument dedicated to the study of the direct interaction between droplets or bubbles. Systems like emulsions or foams or foamed emulsions consist of ensembles of drops or bubbles or mixed drops and bubbles. The direct interaction of these entities yields information on the stability of the

    In eye emulsions or suspensions, the bioavailability (i.e. the residence time and duration of the effect, the rate of release and the absorption of the eye drops) depends on the particle size of the disperse active ingredient. In addition, overly coarse active ingredient particles can irritate or damage the eye

    8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight
