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
The Pennsylvania Granulator is the most widely installed crusher of its type in the entire power generation industry including both utility and independent producers This crusher together with the Pennsylvania Bradford Breaker and our other coal crushers performs the sizing of an estimated three fourths of all steam coal used in the
Size reduction depends not only on the number of collisions but also depends on the intensity of collision; a particle breaks if the collision impact force is higher than a certain threshold impulse which varies with coal to coal Size reduction in an impact crusher can not be modeled by single particle breakage phenomena because it accounts
In this study the effects of three different choke feed level 1/1 1/2 and 1/4 and four different effective reduction ratios 5 10 and 20 depend on the capacity of the crusher of the
They are suitable for a wide range of materials including limestone coal shale and gypsum Choosing the right impact crusher Choosing the right impact crusher depends on several factors including the type of material being crushed the required product size and the operating conditions of the machine
