Jet Mills. A jet mill, or fluid energy mill, grinds material by using a high speed jet of compressed air or inert gas to impact particles into each other. Jet mills can be designed to output particles below a certain size, while continue milling particles above that size, resulting in a narrow size distribution of the resulting product.
Roller mill: 3. Impact · In this, the substance is subjected to hammers or bars at high speed · Impact also occur when a forceful particle is strike against a stationary object: Almost all drugs are size reduced by hammer mill. Fluid energy mill is used for moderately hard and friable materials: Hammer mill. Fluid energy mill: 4.
Larger particles are fed through an opening of the cylinder. The opening is closed. The cylinder is rotated at the critical speed of ball mill. The optimum size reduction in a ball mill depends o the following factors: Feed quantity: Too much feed will produce cushioning effect and too little feed will produce loss of efficiency of the mill.

Ball Mill. The ball mill's basic concept dates back to prehistoric times when it was used to grind flint for pottery. A pharmaceutical ball mill is a type of grinder that is used to grind and combine materials in the production of different dosage forms. Impact reduces the size of the balls as they fall from near the top of the shell.

If both the discs counter rotate, the particle size may be reduced to 2 micro meter. Pin mills may grind tons/hr. Depending on the product end size of particles and capacity, the energy consumption may vary from 3 to more than 100 kW. The specific energy consumption is10 100kWh/ton at peripheral velocities 100 200m/s Usually the ...
Hammer mills are best for brittle, friable, nonabrasive materials. Universal Milling Universal mills are, as their name implies, versatile. Depending on the application and the product, these mills can be equipped with up to four rotating and stationary milling elements to dry grind mill feed to particle sizes ranging from 50 microns to 2 ...
12. If the rate of feed increased, coarser product will be obtained and if speed of rotation is increased the fineness for a given capacity is increases. During grinding, the balls themselves wear and are continuously replaced by new ones so that mill contains balls of various ages. Ball mill produces 1 to 50 ton/hr of powder and energy requirement of the ball mill is about 16 kwh/ton.
