A sectional view of the single-toggle type of jaw crusher is shown below. In one respect, the working principle and application of this machine are similar: the movable jaw has its maximum movement at the top of the crushing chamber, and minimum movement at the discharge point. The motion is, however, a more complex one than the Dodge motion, being …
Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).

• Start the jaw crusher and find the power consumption under no load condition with the help of energy meter and a stop watch. • Prepare the sample you want to crush in the jaw crusher. • Feed the above sample of coal to a jaw crusher and crush it. Measure the time for crushing.
A final calculation is now performed to arrive at the amount of original feed which, when added to the circulating load, will equal the capacity rating of the crusher at each trial setting. The formula for this calculation is: (III) Tones of fresh feed = Crusher Capacity / ( 1 + Circulating Load in Decimal)

The calculation of power is carried out for a single act of crushing, that is, with the destruction of one original piece with subsequent correlation, taking into account the ... Compression crushers are divided into the following types: jaw crushers, in which destruction occurs due to the opposite working movement of the plates [2]; roller,
Jaw crushers are used as primary crushers in a mine or ore processing plant or the first step in the process of reducing rock. They follow "crush using compression" mechanism.
Average throughput rate of single-toggle jaw crusher, standard version, tolerance ± 10% Double-toggle jaw crushers Design Double-toggle jaw crushers are equipped with a double-toggle system, which is con - trolled by a pitman that moves up and down under the influence of an eccentric shaft, causing the toggle plates to alternately flex and ...
The moving jaw rotates around the eccentric axis as well as swings around the same center (Fig. 2).By removing the moving jaw suspension shaft and the front toggle plate of simple pendulum jaw crusher, and suspending the moving jaw on eccentric shaft to combine the connecting rod and the moving jaw into whole, a compound pendulum jaw crusher takes shape, which is …
Abstract--- The objective of the present work is to improve the performance of a jaw crusher, is mainly determined by the kinematic features of the liner to optimize the frame, design the …
