As can be seen in Table 2 the temperatures of self- heating generally increased in the samples from the Rolls Crusher and Raymond Mill. However the values for the material from the Ball Mill Mill (grinding) Wikipedia,A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank),

    Lignite is a kind of mineral coal with minimum coalifiion degree. Because it is rich in volatile elements, it is easy to be burnt and generate smoke.effect of grinding on porosity and surace area of coal.,PRODUCT 20 30 materials characterized by smaller pores are fractured, resulting in lower comminu- tion rates. The change in porosity with time is shown qualitatively in the micro- graphs of lignite particles in Figure 1. creases with increased ball milling time. When the closed pores are opened, the density and surface area
