Restoring your crushing equipment to top condition during the winter months is critical to ensure a smooth spring start-up. Here are a few quick tips to keep your crushers running smoothly.

HSI crushers

Weigh the effects of feeding steel and other non-crushable material through your equipment and how that can negatively impact the wear parts, rotor bearings, and other key components.

Blow bar wedges are often overlooked, but keeping these in good condition will better support the blow bars and help reduce breakage.

Vibration can wreak havoc on your crusher. Make sure to routinely clean uneven material buildup on the rotor and inspect for uneven wear, rebalancing as necessary to avoid costly damage to rotor and bearing components.

Blocked feeders and machines set out of level can cause focused wear on the low sides. Make sure to check and maintain level in both directions whenever possible.

Jaw crushers

Inspect pitman labyrinth seals for looseness, and clean any built-up dust and grease. Clean bearing housing vents, and keep an eye out for cracked or deficient components such as tie bolts and toggle plates.

Inspect all wear components and wedges for excessive wear, cracks or missing fasteners.

Cone crushers

Inspect your feed point to ensure the cone is receiving material directly on the center of the feed opening. This has a major influence in your yearly maintenance cost per ton. Look for cracks in areas such as the adjustment ring, and check the integrity of the mainframe liner.

For hydroset cylinders on floating shaft gyratories, check the lubrication system supply lines for leaks or sweats and change the lube oil and filters.

General maintenance

Making sure to include the feeding system in your general overall inspection can help prevent crushing inefficiencies caused by a blocked or damaged grizzly.

Inspect the crusher drive components for loose or damaged belts and worn sheaves, and ensure that the belts are correctly tensioned. Ensure guard systems are properly secured. Inspect all hydraulic components for leaks. It’s good practice to start with clean lube oil and filters, so all oil-lubricated bearings should be drained and flushed. Grease all fittings as prescribed in your service manual.

Lastly, stay out in front of your wear parts needs. A quick call to your local supplier can go a long way in making sure they have the parts you need, when you need them most.
