The Muncie four-speed transmission has its roots back to 1935 and the U.S. patent number 3,088,336 along with an engineer named James W. Fodrea.

The shaft extension is provided to reduce the relative strain between the head and shaft and thereby reduce fretting in the fit, which has a heavy press. The shaft diameter is 50 percent greater than the 7 ft. …

The second design muncie (1967-1968) increased the cluster shaft diameter 7/8ths inch and included the second design selector (side) cover with the larger diameter pin externally pressed in to prevent it from shaking loose from the case. Selector shafts studs increased to 3/8ths inch. The 10-spline input shaft remained.

After finding the main reason for the fracture of the gyratory crusher main shaft, we study how to reduce the probability of the main shaft breaking.

Robust frame design and large diameter, forged main shaft with no threads or sharp radii that can cause stress concentrations.

The main shaft is eccentric and on this eccentric shaft is mounted the movable jaw, imparting a rotary movement to the jaw. This rotary movement followed by the movable jaw actually pushes the feed down into the crusher, as well as crushing.

The gap between the main shaft and concaves reduces from the top to the bottom of the crusher assembly. The upper concave is lined with hardened steel concave linings and …

It is a development of the secondary gyratory crusher, which is merely a small gyratory crusher designed to break the product of the primary machine down to about 1½-in. size; but the main shaft of a …

GP cone crushers have a simple but strong top and bottom supported shaft design which ofers mechanical reliability, and where the main shaft participated in the crushing kinematics.

CG830i crusher offer excellent reliability and safer & faster maintenance – up to 30% faster than competing crushers. A robustly designed one-piece main shaft and reinforced shells are made for tough use. The one-piece spherical spider bearing offers 5 times longer wear life than competing spider bushing design.

Resistant U-shaped arched spider, durable manganese bronze spider bushing, new shell separators and inspection ports, as well as hardy one-piece main shaft makes the Superior™ MKIII 60-89 primary gyratory crusher efficient and …

The gyrating motion of the eccentric causes the main shaft, which is free to rotate around its own axis, to rotate slowly in the same direction as the travel of the eccentric when the crusher is empty and in the opposite direction when the crusher is working.

ne of the main primary crusher types used in mines and quarries. The size designation of gyratory crushers

New for the hammer can be hung on the shaft hole diameter of 490 mm, and when the hammer wear can also continue to use, to put this somewhat worn hammer hanging in the shaft hole diameter of 520 mm and can continue to use the doing, not only can extend the life of the hammer, while maintaining hammer crusher crushing effect and reduce ...

Standard. Offline lubrication filtration unit. Optional. Former name: H6800 Cone crusher. Several standard crushing chambers are available for each model. The crushers can easily be matched to changes in production selecting the right crushing chamber and eccentric throw. The chambers available are: EC = Extra coarse. CX = Coarse xtra.

With so many factors impacting cone crusher selection and performance, it can be challenging to maximize productivity without expertise. Improperly sized or selected crushers lead to increased downtime, higher operating costs, and uneven wear.

CS660 cone crusher has a hydraulically supported main shaft that is supported at both ends. It also has a robust crusher design, adjustable eccentric throw, and a constant intake opening. This crusher is suitable for a high-capacity secondary crushing application.

The main parts of this crusher are: The stationary conical crushing ring (1), the mobile crushing cone (2) mounted on the main crusher shaft (3). The main shaft with the crushing cone is oscillating suspended from a ball and socket joint located in the upper crusher housing (spider).

There are two main types of impact crushers: horizontal shaft impactors (HSI) and vertical shaft impactors (VSI). HSI crushers utilize a horizontal rotor that throws the material on stationary anvils or curtains, which results in the material breaking upon impact. VSI crushers, unlike the traditional crushers, have a vertical rotor which ...

The pedestal-type main shaft is rigidly held in a tapered bore in the center of the crusher frame. The main shaft is forged of high-strength alloy steel. Abrasion-resistant wear liners and guards provide extra protection to …

The following are either obsolete types of gyratory crushers, of which many are still in service, or are older designs with extremely limited capacity: long-shaft spider …

The MIV800 Vertical Shaft Impact Crusher guarantees smooth operation at high speed with a long service life and superior crushing results.

Vertical shaft impact (VSI) crusher is widely used for quaternary, tertiary, and secondary applications of crushing rock, cement clinker, quartzite, and concrete aggregate and especially for the sand making and road paving.

The 1966 main cases saw some additional design changes. With the introduction of the 3885010 case, the countershaft bore was increased to 1 inch. The case countershaft bore usually stretched out so the increase in shaft diameter …

The shaft extension is provided to reduce the relative strain between the head and shaft and thereby reduce fretting in the fit, which has a heavy press. The shaft diameter is 50 percent greater than the 7 ft. crusher shaft.

The main body of the crusher is primarily composed of a roller, an eccentric shaft, and a fixed concave plate. Under the action of the eccentric shaft, the roller intermittently approaches and moves away from the fixed concave plate.

A gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory crushers can be used for primary or secondary crushing.
