Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32" from jaw die to jaw die at the top opening or gape opening and 54” across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.

Impact crushers provide better grain-size distribution of RA for road construction purposes, and they are less sensitive to material that cannot be crushed, such as steel reinforcement. Generally, jaw and impact crushers exhibit a large reduction factor, defined as the ratio of the particle size of the input to that of the output material.

Coal handling plant of thermal power station –A New Approach By Makarand Joshi 1.0 Abstract:
Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size.. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.

This comprises the belt conveyors within the crushing and screening plant, the crushers and the screens. Coal from the mines varies to great extent in its size. So it is required to crush upto required size. For this various types of crushers are used. There are four basic ways to reduce material: by impact, attrition, shear or compression.

But, impact crushers involve an impact method. There is a hopper one side that takes the crushing material into the machine. All material is carried only within a cage. This cage has an opening on the end, bottom and on the side. These openings help in escaping the pulverized material from the impact crusher.

Impact In crushing terminology, impact refers to the sharp, instantaneous collision of one moving object against another. Both objects may be moving, such as a baseball bat connection with a fast ball, or one object may be motionless, such as a rock being struck by hammer blows. There are two variations of impact: gravity impact and dynamic

Impact crusher. Impact crushers involve the use of impact rather than pressure to crush material. The material is contained within a cage, with openings on the bottom, end, or side of the desired size to allow pulverized material to escape. There are two types of impact crushers: horizontal shaft impactor and vertical shaft impactor.
