Cone Crusher  Spider Cap

The cast steel spider cap has been designed to serve as a feed distribution plate for coarse materials. It is recessed on the 22, 30, 36 and 48-in. crushers. For fine materials, the wobble plate feeder — a more effective means of distributing the feed — is recommended.

Top Shell And Spider

The annealed cast steel top shell and spider are made in one piece. The spider is of the three arm type, equipped with a self-aligning, Scor-Proof plastic ball and socket bearing in crusher sizes 22 to 48-in., and with an hourglass type bearing in sizes above 48-in. The lubricant is sealed in with a garter type oil seal. Bearings can be lubricated from outside the top shell on the 51, 60 and 84-in. crushers through oil holes in spider caps of the four smaller sizes.

Cone Crusher Mainshaft

The mainshaft is of high grade forged steel, annealed for stress relief. It is tapered to gauge for head center fit. The bottom of the shaft is fitted with a polished bronze step bearing. The journal for the spider bearing is formed by a sleeve shrunk on the shaft on the 51, 60 and 84-in. crushers. Short, heavy mainshaft design results in a long life.

Head Center

The mainshaft is fitted with a steelhead center that bored and turned to gauge for shaft and mantle fit.

Cone Crusher Step Bearing

The step bearing consists of a bronze mainshaft step, a bronze piston wearing plate, and an alloy steel washer between the two. The washer is drilled for oil cooling and lubrication. Both the mainshaft step and the piston wearing plate are made of high lead bronze, selected to give the best bearing surface. The washer and plate are pinned in place, and the bearing surfaces are grooved to permit the distribution of the lubricating oil.

Cone Crusher Dust Seal

The dust seal is a plastic ring suspended in a housing from the head center and encircling the dust collar. It is designed to accommodate the vertical adjustment and the gyrating and rotating motion of the head. All wearing parts are replaceable. The crusher is fitted with a connection for introducing low-pressure air inside the seal for additional dust protection.

Cone Crusher Eccentric, Gears, Pinion-shaft

The eccentric is made of high carbon cast steel and fitted with a bronze inner wearing sleeve. The eccentric turns in a bronze bottom shell bushing. Both sleeve and bushing are replaceable. The eccentric throw can be changed in the field by installing a different sleeve.

The alloy steel gear, keyed to the eccentric, is a bevel spur gear in Hydrocone crusher sizes 22 to 48-in., and spiral bevel in crusher sizes above 48-in.

The alloy steel pinion is mounted on a turned shaft. The cast steel pinion shaft housing is bolted to the machined opening in the bottom shell. It is equipped with anti-friction bearings sealed inside and out and has separate pool lubrication in all sizes except the 36 and 48-inch machicone-crusher-bottom-shellcone-crusher-bottom-shellnes. The 36 and 48-inch Hydrocone crushers have sleeve type counter-shaft bearings that are lubricated by the external oiling system.

Cone Crusher Bottom Shell

The annealed cast steel bottom shell is of the three arms, open discharge type, bored to gauge for the top shell and eccentric bushing. It is boring and faced for the bottom plate, pinion shaft bearing and dust collar.

Cone Crusher External Oiling

The external oil conditioning system furnished with Hydrocone crushers consists of a large oil storage tank on which are mounted a condenser type cooler, pressure type filter, motor, and a pump which pumps the lubricant to the crusher automatically. These units both cool and filter the oil. The accumulator and tank for the Automatic Reset are mounted separately from the oil storage tank.

All oil conditioning systems are equipped with oil flow and temperature safety switches which are adjusted to open the motor circuit and stop the crusher if the temperature becomes too high or if there is not a sufficient flow of oil. A flexible hose connects the lubricating unit to the crushers, greatly reducing the number of pipe fittings required and simplifying the installation.

Oil for the tank is pumped through the filter and cooler to the step bearing and up the inner eccentric bearing. It flows down the outer eccentric bearing, lubricates the gear and pinion, then returns to the tank. Tank capacities vary from 30 gallons for the 22-in. Hydrocone crusher to 240 gallons for the 84-in. machine.

Adjustment System

To adjust the setting of the machine, hydraulic rams are used to rotate or counter-rotate the bowl in the adjustment ring. The seal between the adjustment cap and hopper is a simple, continuous, tightly fitting flap that allows free, relative rotation but prevents intrusion of dust into the thread area. The lower end of the thread connection between bowl and adjustment ring is also sealed. The hopper assembly, which is actually a part of the bowl assembly, including the hopper, hopper liner and cap closure, comprises the section in which the feed is introduced. It includes a death bed, reducing wear and shock from the fall of the feed from the feeder above.

The adjustment rams are pressurized hydraulically and provide a setting adjustment. For normal adjustment of setting due to wear, installation and removal of the bowl is made through a swivel sheave and a cable turn applied around the adjustment cap. The bowl is then rotated by use of the maintenance crane.

Head-Main Shaft Assembly

The crushing head, similar in section to that of the 7 ft. the machine had three-dimensional photoelastic studies made using the technique of freezing stresses into a loaded plastic model, sectioning the model and examining the slices under polarized light. As a result of these techniques, stresses have been reduced. The core of the head consists of six massive ribs to support the crushing forces on the surface of the head. The head is cast steel.

The main shaft is of turbine rotor steel of high quality and refinement, the chemistry of which is low carbon to reduce the possibility of heat checking. It includes chrome nickel additions for deep hardening, notch toughness and resistance to fatigue. 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. As a result, the shaft operates at lower values of bending stress and deflection. Reduced deflection produces distinct benefits in bearing behavior because of the uniformity of oil film under load. Reduced stresses assure longer life and resistance to overloads.

Socket Assembly

The head-shaft assembly is supported by the socket and socket liner which is, in essence, a spherical thrust bearing. The function is to carry the vertical component of the crushing force while allowing the head to oscillate around the theoretical center of rotation.

The socket of carbon steel is of dowelled design. The forces between the head and the socket are normal to the spherical surface of the head and pass through the theoretical center. The line of action of these forces is such that practically pure compression is applied to the socket and liner, reducing deflection and stress to a minimum and promoting good bearing performance.

Inner and Outer Bearing Design

The force distribution throughout the crusher is based on a vector diagram of the cavity forces during crushing and the reactions at various associated loading points in the crusher. The vector diagram establishes their relative magnitude, direction, and points of application. The actual magnitude of these forces is established by the crushing force necessary to lift the adjustment ring off the frame seat. This condition represents the maximum allowable force for normal crushing.

During tramp passage, bearing forces increase, but this condition prevails for brief periods that are not maintained long enough to overheat the bearing and destroy the hydrodynamic oil film.

Seal Assembly

A baffle ring attached to the head is submerged around its entire periphery in a water trough resting on the socket. Dust tends to settle into the trough and must be continuously removed to prevent caking. For this reason, water is continuously fed through specially designed nozzles that scour the trough. Overflow water is carried off by internal piping and passages. The seal chamber is vented to atmosphere to prevent “siphoning” which may cause oil contamination of the water or vice versa.

Main Drive Gears

The gears are straight tooth bevel gears and are designed to AGMA standards using a computerized program which, upon input of the basic information, such as DP, diameters, gear ratio, material properties, tooth type, provides a complete printout of the rated power on the basis of tooth strength and surface durability of the gear. The factor of safety on the gear is in excess of three on a strong basis and in excess of two on the durability basis.
