Mining operations place exceptional demands on rotating and process equipment. Slurry pumps handling comminution and classification circuits carry high-solids content at coarse particle sizes, and seal face wear or packing failure in these applications can occur within weeks rather than months. Crusher bearings and grinding mill drives operate under continuous load and shock forces in remote locations where maintenance access is limited and every hour of downtime has a direct cost.
Across the milling process — from primary crushing and screening through flotation, dewatering, and tailings handling — equipment runs continuously and the consequences of failure compound quickly. Conveyor systems, thickener drives, and filter press pumps all carry the same risk: a bearing running hot or a seal weeping slurry that goes undetected long enough to cause catastrophic failure. Most mills maintain a backup pump inventory specifically because unplanned downtime is not an option.
Chesterton provides mechanical seals, compression packing, ARC wear coatings, industrial lubricants, and condition monitoring solutions proven in mining service. Our specialists work with maintenance teams across comminution, beneficiation, concentration, and tailings processing — bringing product knowledge and application experience to the specific conditions found in each part of the process.

- Wear and corrosion protection for pump casings, chutes, and sumps
- Condition monitoring for remote and unmanned equipment
- Sealing solutions covering both wet-end and drive-side pump applications
- Local service specialists with documented mining application experience
Our Solutions for Mininig
Mechanical Seals
Chesterton mechanical seals are designed for slurry pump service in comminution, classification, and tailings circuits. High-solids abrasive slurries accelerate seal face wear rapidly, making product selection and correct installation critical to achieving acceptable service life. Split seal designs reduce maintenance time in high-changeout environments.
Mechanical Packing
Chesterton compression packing extends service intervals on slurry and tailings pumps where mechanical seals are not the standard solution. DualPac and SpiralTrac-compatible packings are engineered to handle abrasive solids with controlled leakoff and reduced shaft wear, lowering both maintenance frequency and total operating cost.
Industrial Coatings
Chesterton coatings protect pump casings, impellers, chutes, hydrocyclone components, and concrete sumps from erosion and corrosive process water. Coatings restore worn surfaces and extend equipment life without full replacement.
Industrial Lubricants
Chesterton heavy-duty greases and lubricants protect crusher bearings, grinding mill trunnions, and conveyor drives under continuous load and shock. Products are selected for resistance to water washout, contamination, and high operating temperatures.
Polymer Seals
Filter press pumps, vacuum filters, and dryer drives in the dewatering circuit require reliable sealing under varying pressure and solids loading. Chesterton supplies packing, mechanical seals, and polymer seals for the full range of dewatering equipment.
Equipment Monitoring
Chesterton Connect monitors bearing temperature, vibration, and equipment health on remote or unmanned mining equipment. Early detection of developing faults reduces unplanned downtime across large mine sites where manual inspection is impractical.
