CL-20 (8.76 g) and TNT (4.54 g) (molar ratio = 1:1) were weighed and added into an alumina jar. To it, 2 kg of 0.38 mm zirconium beads (2/3 of the cavity volume) and 200 mL of ethanol solution (volumetric ratio of ethanol and water = 1:1) were added. Then, the jar was fixed to a vertical ceramic membrane minimized ball miller.

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula. The mill speed is typically defined as the percent of the Theoretical

RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application. The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time
A cocrystal is a crystalline entity-complex formed by two (or more) different, distinct molecular entities/ingredients, which are solid at ambient temperatures, and within which the intermolecular interactions in the unique crystal lattice generated are weak forces (non-covalent and non-ionic), such as hydrogen bonds, π bonds and van der Waals

Thermal analyses of the samples were carried out on a DSC Q1000 (TA instrument) which was calibrated for temperature and enthalpy using indium. Samples (1–3 mg) were crimped in non-hermetic aluminum pans and scanned from 30 to 300°C at a heating rate of 10°C/min under a continuously purged dry nitrogen atmosphere (flow rate, 50 mL/min).

Ball Mills are the most effective laboratory mills for rapid batchwise comminution of medium-hard, soft, brittle, fibrous, temperature-sensitive and moist samples down to the finest particle size. The comminution of the material to be ground takes place through impact and friction between the grinding balls and the inside wall of the grinding

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T
