A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example, a pulverizer mill is used to pulverize coal for combustion in the steam-generating furnaces of coal power plants. Pulverizers are commonly used in the coal industry but can be suited for a variety of applications. The main purpose of these machines is to process materials and act as size reduction equipment. A pulverizer reduces materials
like Limestone and gypsum at high speeds resulting in smaller particle sizes.

Typically, Pulverizers are sorted into three major groups:

1. Grinding Mills                2. Crushers           3. Impactors

Pulverizer machines may have different components depending on their kind. However, in general, they work using entry feed, a rotating element (e.g. rotating cylinder), a crushing element (e.g. steel balls), and an exit feed. Some pulverizers also have temperature control and air flow components (air pre-cleaner, air compressors, etc.) that help dry newly crushed material. To promote safety, they frequently feature accessories like automatic shut-off programming, shields, sensors, and guardrails. 

When helping you select a pulverizer or when designing a custom pulverizer for you, pulveriser suppliers consider factors like feed quantity, the breaking behavior of the material you will be sending through the feed, its initial texture (coarse, fine, etc.), its level of abrasion resistance, its initial hardness, its initial cleanliness(any contaminants it may carry), and the required finished texture and fineness of the material you are grind.
