Jaw Crushing Processes Flowchat
Crushing and screening processes for aggregates are purpose-designed processes for producing aggregate fractions with pre-specified quality specifications. An aggregate production plant, crushing station, basically involves crushers in series for crushing rocks and screens for classifying and separating fractions measured in size.
Several machines, such as jaw, gyratory or roll crushers use the physical effect of compression to crush hard and brittle rocks. Because of the tremendous expenditures of money and equipment necessary to investigate the comminution of large particles hardly any scientific investigations were carried out so far.
ince machines which use the effect of compression apply a defined displacement to a rock the main crushing properties were gained as a function of the applied throw and the particle size of the rock: likelihood of breakage, maximum crushing force, mass specific crushing work, crushed fragment size distribution, crushed fragment shape distribution.
