The benefits of using a pulverizer are numerous. It can help you create. Breaking Up Tough Soil. For breaking up tough, compacted soil, many landscapers and farmers rely on pulverizers. These machines use heavy-duty teeth and roller spikes to shatter hard soil, making it easier to work with and promoting healthy plant growth.

Dynamic classifiers: These incorporate a rotating rotor and, consequently, have a wider operational range. High efficiency classifiers: These combine useful elements both of the above technologies by using a static set of vanes to guide the airflow into a rotating rotor, alongside other optional features.

The purpose of the coal drying system is drying and grinding the raw coal for stable transportation of pulverized coal to gasifier and stable/high-efficiency gasification at the gasifier. In the same way with conventional coal firing boiler, raw coal fed from coal bunker is dried and grinded in the coal pulverizer.
