Pulverizers/
In the past, pulverizer manufacturers harnessed forces with natural sources. Windmills transformed the power of wind into rotational motion, and waterwheels did the same with river and stream currents. Human and animal power was also used to generate the rotational motion needed for early industrial grinding processes. Today, particularly in more developed economies, most pulverizers, grinders and crushers are operated by motors. Manufacturers offer their clients many different kinds of pulverizers, including ball mills, hammermills, jaw crushers, roll crushers and many other kinds of equipment. A ball mill is a cylinder partially filled with a grinding medium, like small stainless steel balls. When rotated on its axis, the material that fills the rest of the cylinder is crushed. Hammermills use hammers to crush material, while jaw crushers crush material between two plates. Roll crushers, in contrast, crush material between two rollers or between a single roller and a fixed, flat plane. Pulverizers are common in industrial settings and are used to break up material for removal, transport or recycling purposes. Pulverizer manufacturers are also used to grind grain for food and to make paint, ceramics, and pharmaceutical products.
Pulverizers, crushers, grinding mills and all other size reduction equipment varieties are all important industrial utilities. Crushing and grinding are important steps in the development of many of the products that have become important parts of daily life. Coal, for example, which is used to generate a very substantial percentage of electricity worldwide, generally must be processed before it can be used. Grinding of fuel materials like coal increases its surface area, which makes the coal burning process more efficient. Other important mineral-based products also must undergo grinding or crushing processes before they become usable. The same can be true of a large variety of both ferrous and non-ferrous metals. Ceramics, paint and even gunpowder for use in pyrotechnics displays are all often subject to grinding or crushing processes at some point in their development.
