The roll crusher consists of a pair of horizontal cylindrical manganese steel spring rolls (Fig. 13.14), which rotate in opposite directions. The falling feed material is squeezed and crushed between the rollers. The final product passes through the discharge point. This type of crusher is used in secondary or tertiary crushing applications.
• Inspect discharge and feed areas. If the discharge belt is not running, the crusher will fill and get plugged with material – and often times, the operator cannot see the discharge belt. Schmidt recommended …

Maintenance from wear side. For crusher discharge vaults, the Xlok system is our preferred solution. It is a tough modular liner system designed to be accessed only from the inside of the chute. Xlok increases the wear performance of the area and reduces the maintenance work and reline time. Each individual liner can be easily handled and ...
The changes in discharge granularity (parallel bond number) with MSA, CA, EA, MSS, and their first-order interactions are shown in Fig. 10, the black line in Fig. 10 (a) to (d) represents the discharge granularity, and the area surrounded by the red line represents a 95% confidence band. It can be seen that with the increase of MSA, CA, …
Consistent crushing at high throughputs – our Jaw Crusher EB is the solution for crushing medium-hard to very hard materials. ... such as the enhanced kinematics of the swing jaw with a high stroke in the feed and discharge area, which guarantee you very high throughput rates. However, these are just a few of many benefits of our Jaw Crusher EB.
For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft.
A horizontal single deck screen is required for a crusher plant that produces quartz with a bulk density of 90 - 100 lbs/ft3 and a top size of 2 mm. The crusher discharge is to be fed to a screen at 159.81 th. The required open area and separation efficiency are 82% and 68%, respectively.
• Electronic control of crusher discharge opening and feed rate. With adjustment of a crusher's discharge opening, as the production continues through an on-line coarse size analysis of the crushed product (digital image analyses). Dance, A. 2001) • More attention is being paid to the impact on crushing circuit design caused by variations

The following factors will enhance crusher capacity and performance: 1: Proper selection of the jaws 2: Proper feed gradation 3: Controlled feed rate 4: Suicient feeder capacity and width 5: Adequate crusher discharge …
That area is not considered part of the crushing chamber. Periodic oil sampling of the bearings is advised when oil lube is used. The discharge conveyor and under-crusher hopper should be wider than the discharge width of the crusher. Sufficient tension must be placed on the toggle plate to ensure proper alignment.
The discharge area refers to the part of the crusher where the crushed material exits the machine. If the discharge area is not adequate, it can lead to material buildup, blockages, and decreased …
Build-up in the discharge area can also cause wear. • Once again, fluid contamination (fuel, hydraulic and oil/lubricants) was brought to the forefront of crusher maintenance procedures. Schmidt suggested any bulk fluids going into storage tanks should be pre-filtered when stored and again when servicing equipment.
Jaw Crusher Discharge Settings "X" dimension equals Peak-to-Peak measurement. To set the Closed Side Discharge Setting, use a wood block with the same width as the desired setting. It should be. long enough to span most of the crusher's discharge area. NOTE: When the crusher is at rest, it is NOT in the closed position.
The performance and capacity of the coarse crusher depend on the following parameters. 1# Quantitative Feeding: Adding an appropriate amount of the feed in the coarse crusher is responsible for better performance. Always fill nearly 60% of the total volume of the coarse crusher to optimize the working speed. 2# Adequate Discharge Area:

Due to the change of wear and particle size requirements of finished products, the size of the discharge port needs to be adjusted from time to time. Generally, the size of the discharge material can be controlled by adjusting the crusher plate and wedge block. The adjusting plate is generally located behind the toggle seat inside the …
The primary gyratory crusher offers high capacity thanks to its generously dimensioned circular discharge opening (which provides a much larger area than that of the jaw crusher) and the continuous operation principle (while the reciprocating motion of the jaw crusher produces a batch crushing action).
