Cone Crusher Winter Startup: Essential Checks and Procedures for Cold Climates
September 5th 2025
The reliable operation of a cone crusher is vital for any quarry or mining operation. However, starting this heavy-duty crushing equipment in sub-zero temperatures presents unique challenges. Cold weather can drastically affect a crusher’s components, thickening lubricants, making hydraulic fluids sluggish, and causing seals to become brittle. A standard startup procedure in these conditions can lead to catastrophic damage and costly downtime.
This guide outlines the critical steps and safety checks for a safe and effective cone crusher cold weather startup, ensuring your machine operates reliably all winter long.

Pre-Start Checks: The Foundation of a Safe Startup
Before you even think about starting the motor, a thorough pre-start inspection is non-negotiable. This is the most important step in cone crusher cold weather startup.
Lubrication System: This is your top priority. Cold temperatures increase oil viscosity, which can starve bearings of proper lubrication and cause severe damage.
Check the oil level in the lubrication tank.
Ensure you are using a winter-grade oil recommended by the manufacturer.
If your system has a heater (a critical feature for cold climates), turn it on and allow it to warm the oil for at least 30-60 minutes. The oil temperature should reach the manufacturer’s recommended operating range before the crusher motor is started.
Hydraulic System: Like oil, hydraulic fluid also thickens in the cold.
Inspect all hydraulic hoses and seals for signs of brittleness or cracking.
Check the fluid level and, if equipped, activate the hydraulic system heater to warm the fluid.
General Inspection:
Walk around the machine and inspect for any ice buildup on the crusher, conveyor belts, or screens. Ice can cause severe damage upon startup.
Check the V-belts for proper tension. Cold rubber is less flexible and can break if subjected to sudden, high-torque starts.
The Cold Start Procedure: A Step-by-Step Guide
Once all pre-start checks are complete and your lubrication and hydraulic fluids are at the proper temperature, you can begin the startup procedure.
Warm Up the Systems: With the crusher motor off, turn on the oil pump and allow it to run for several minutes. This circulates the now-warmed oil throughout the system, ensuring all bearings are lubricated before the main shaft begins to turn.
Start the Crusher Motor (Empty): Once the oil pump has run for a sufficient time, start the crusher motor slowly and allow the machine to run empty for a few minutes. Listen for any unusual grinding or squealing sounds. These could indicate stiff bearings or other issues.
Monitor and Wait: Keep a close eye on the motor’s amperage draw. It will likely be higher at the beginning but should normalize as the crusher reaches its normal operating temperature.
Begin Feeding Slowly: Only begin feeding material once the crusher is running smoothly and consistently. Start with a very low feed rate and gradually increase it. This allows the machine to warm up further under a load without being overstressed.
Operational Tips for Winter Crushing
Continuous Monitoring: Throughout the day, continue to monitor oil temperature and pressure. Be alert to any sudden changes that could indicate a problem.
Preventing Freezing: At the end of a shift, always run the crusher empty for a few minutes to clear all material from the chamber and the discharge chute. This prevents wet material from freezing inside the machine overnight, which can cause a serious blockage or damage upon startup the next day.
Consider a Shelter: If possible, store the cone crusher in an enclosed space or use a temporary shelter to protect it from harsh wind and snow. This can significantly reduce the startup time and the stress on its components.
Following these essential cone crusher winter operation procedures is crucial. It’s not just about avoiding a single breakdown; it’s about protecting a significant investment, maximizing uptime, and ensuring your business can operate productively throughout the cold season.
