Useful Maintenance Tips for Crushers under High ...

In a high-temperature environment, the crusher’s own temperature will rise, and be prone to unpredictable anomalies, such as suddenly shut down, spindle broken and other malfunctions. Because of the principle of hot and cold contraction, high temperature will cause the parts of the crusher to expand, resulting in more friction and deviation in the bite of the components.

Apr 01, 2012  At 1200 °C, the maximum volatile yield is 62 wt% and it increases to 67 wt% at 1400 °C. In entrained flow gasification experiments with Rhenish lignite a high level of conversion is measured at atmospheric pressure and at 0.5 MPa. At both pressures, coal conversion increases with temperature and residence time.

Primary Crusher - an overview ScienceDirect Topics

In general, coal crushers are categorized into two types and three types of primary crushers, as follows: Primary coal crusher: Used for larger coal size. The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is acceptable to the secondary crusher.
