Reduce downtime and improve the flexibility, capacity and safety of your Symons crusher with the Sentinel hydraulic crusher clearing and tramp release system, exclusively from EXCEL.

Manual cavity clearing can take up to five hours and is very dangerous. Automated cavity clearing, on the other hand, is completely safe and has you back in operation in less than 15 minutes! Keep your employees safer, and your operation more profitable!

Product highlights

• Simplifies crusher cavity clearing
• Drastically reduces costly downtime
• Reduces “ring-bounce” and cuts down on related maintenance/repair costs
• Requires little or no modification to your existing Symons frame
• Maximises tonnage – adjust the crusher to a smaller setting without risk of stalling

Hydraulic power unit

The Sentinel’s hydraulic power unit (HPU) offers constant monitoring of hydraulic pressures, temperature and filter conditions. Indicator and warning lights advise the operator of reservoir oil level, oil temperature, oil pressure in the tramp and lock post hydraulic circuits and filter status.

The sentinel advanced hydraulic system also offers options for remote bowl adjustment that allows for quick changes to the closed-side setting (CSS) and simplifies the process of turning the bowl for liner changes.

Checking your head sealing ring and socket sealing ring at each liner change (or at least once a year if liner life exceeds twelve months) ensures that the socket sealing ring is not changed more or less frequently than necessary. This check will also give advanced warning of head sealing ring and/or spherical bearing seats which need to be rebuilt or replaced. Proper maintenance of these two areas will reduce oil contamination and thereby increase the life of the spherical bearing seat (head ball) and all internal parts of the crusher.

Advance warning

The head ball and sealing ring templates are positioned on the main shaft to check the contour of those areas. Monitoring the contour and position of the spherical bearing seat provide advance warning of the need to rebuild (to re-establish both proper running clearance between the main shaft and inner eccentric bushing and proper contact).

Quick check

3/16” gap between the template and the part indicates a condition that needs attention. In some cases, such as an out of contour condition on the spherical bearing seat, a much smaller gap can be a problem.

New & exclusive

Our socket sealing ring template is an exclusive new innovation. It is positioned against the bore of the socket sealing ring and checks the contour of the sealing surfaces and their relationship to each other.

Get the most from your Symons Cone Crusher with our exclusive pre-packaged tune-up kits. They are specially packaged for extended shelf life, and ready to use at a moment’s notice.

Product highlights

• Savings & convenience for all Symons Cone Crushers
• Vacuum-heat packaged on oil-impregnated boards
• Long shelf-life without oxidation or dust contamination
• Reduced potential for misplaced parts
• Easily cut loose only the parts needed at a given moment, leaving the other parts identified, sealed, protected and easily locatable when required

• Completely sealed top: Prevents dust and water from entering the cylinder and damaging the seals and all critical components. Also helps increase reliability and durability of the design.
• Large wear band in the piston and the gland: Prevents side loading from damaging the cylinder ID and the outer rod, extending the life of the seals and all critical parts.
• 100% interchangeable with OEM design: No additional fittings or hoses required
• Available for Symons crushers: We stock hydraulic lock posts for Symons 4 1/4, 5 1/2 and 7 for both standard and short head designs
• Clamping cylinders for HP® and Omnicone®: We also stock clamping cylinders for the HP and Omnicone series of crushers. Call your sales representative or inside sales support person for details.

Feeding a crusher with the best possible distribution is the first step to maximum crusher production. Incorrect feed arrangements cause higher power consumption (higher bearing loads), lower throughput, higher manganese wear, lower reduction, poorer product shape and higher costs. Every application has its own unique requirements, and we've developed feed distributor options and main shaft extension kits in order to improve your productivity and reduce your costs.

Although larger feed plates typically do a better job of evenly distributing the feed with minimum segregation, smaller feed plates and spherical nuts allow a more open view of the feed zone, which better facilitates monitoring via camera, laser, etc. Smaller feed plates and spherical nuts also reduce the damaging effects of feed that falls long distances (five feet or more) crashing onto the outer edge of the feed plate. Plus, these smaller components can make clearing out a jammed crusher much easier and safer.

More than a low-cost alternative

While slightly lower in cost than the conventional assembly design, our feed distributor options offer significant advantages:

• They open up the feed hopper and feed cone area in order to create a clear view for a camera or other modern sensor system used to monitor the feed rate
• They facilitate easier and safer clearing of a jammed crusher 

In most cases, the feed plate used is an existing dead-bed design common to standard crushers. These deadbed designs usually last longer than the conventional flat design for short head crushers.

We’ve created a short head cone crusher for both Symons® 4, 4¼’ and 5½’ Short Head Crushers. The advantage of the main shaft extension combined with a main shaft nut arrangement facilitates a faster, easier and safer removal of old liners. The addition of a torch ring makes this safety and convenience possible.

Operators spend a great deal of time welding a lug onto the old locking nut, only to pound on it for hours to remove it! Occasionally the mantle is even “rolled over,” making it nearly impossible to remove the locking nut without torch cutting or carbon arcing. Unfortunately, torching exposes personnel in the vicinity to the dangerous fumes of burning manganese, epoxy crusher backing material and zinc.

Our torch ring is made of low carbon steel and is small in diameter. In our design, the torch ring is located well above the backing cavity and manganese mantle. While burning the torch ring is not completely risk free, this torch ring can be cut more quickly and safely than most conventional methods.

For special applications, a spherical main shaft nut can be utilised on short head crushers with this arrangement.

Please note that converting to the main shaft extension arrangement requires the crusher countershaft to be run in a counterclockwise rotation, which is opposite of how most locking collar/locking nut arrangements are run. For crushers with integral oil pumps, this requires the inlet and outlet on the pump to be reversed. For crushers with independent oil pumps, no changes other than reversing the crusher rotation are required.
