· Iron sulfide is the most prominent contaminant in natural-gas pipelines and compression equipment in pipeline, refinery, gathering, and storage applications. When black powder collects in gas pipelines it causes wear, reduces efficiency in compressors, clogs instrumentation and valves, and leads to flow losses.

Impact Crushers. The impact crusher, also known as the impactor or horizontal shaft impact crusher, is a equipment that uses impact energy to crush medium-hardness brittle materials finely. Commonly used in various applications including construction, mining and recycling. Impact mills can produce a high-quality cubic end product.

The main iron ore mining equipment includes jaw crushers, ball mills, magnetic separators, spiral classifiers, jig concentrators and related auxiliary equipment …

Impact crushers rely on gravitational or dynamic physical impact for size reduction of materials such as rock, concrete, gravel, and more, rather than through a standard compression-only method of crushing. Typically, impact crushers either use gravity to drop material onto a surface, or the material is fed into a chamber c…See more on williamscrusher
