This article focuses on two widely used types: the hammer mill and the jet mill. Hammer mills are often used for generalpurpose grinding and the finished product particle size ranges from millimeters to tens of microns. The jet mill is primarily used for superfine grinding applications and creates particles sizes down to a few microns.

The principle objective for controlling grinding mill operation is to produce a product having an acceptable and constant size distribution at optimum cost. To achieve this objective an attempt is made to stabilize the operation by principally controlling the process variables. The main disturbances in a grinding circuit are: 1.

Introducing a wiper flat in an insert design is an effective way to improve surface finish. Today even roughing milling inserts can have an integrated wiper (see Figure 1). Even doublesided inserts can have a wide wiper flat. These tools are intended for roughing and semirough milling and usually require a semifinishing operation to finish.

Ensuring safe processing. When thinking of safety in milling and grinding, mechanical accidents might come to mind. With spices, processing can also start a fire through, for example, a dust explosion. "Spices are organic products, which have the ability to explode at a certain fineness under certain conditions," Kästl notes.

A traditional jet milling process is often operating with grinding nozzle pressure of around 7 barg at 250˚C. An air compressor must use notable amounts of energy to achieve compressed air at this pressure and temperature. Even more energy is used if the air must be oilfree and dry, which is common in jet milling processes.

Grind curves give the steadystate values of the performance variables throughput, power draw, and grind in terms of the mill filling and critical mill speed. The grind curves indicate the operable region of the grinding mill. An analysis and dynamic simulation of the model show that the model captures the main dynamics of the grinding mill.

millstone, one of a pair of flat, round stones used for grinding grain. One millstone is stationary; the other rotates above it in a horizontal plane. Grain is poured through a hole in the centre of the rotating millstone, flowing into shallow grooves, called channels, which radiate from the centre of the stationary millstone.

Grain mills come in a variety of sizes and shapes, and can be either handpowered or electric. To grind wheat into flour using a grain mill, first add the wheat kernels to the mill. Then, turn on the mill and watch as the wheat kernels are crushed between the mill's grinding stones. The resulting flour will be collected in a container.
