The Mn13Cr2 Advantage: more higher Lifespan & Cost Efficiency

Our rollers and rings are cast from proprietary Mn13Cr2 premium alloy steel, ensuring higher impact toughness and work-hardening capabilities.

When applied to limestone grinding, we offer a highly conservative and guaranteed service life benchmarking:

MTW175 Grinding Roller Lifespan: 8,000+ Hours (Minimum conservative guarantee)

MTW175 Grinding Ring Lifespan: 16,000+ Hours (Long-lasting performance)

Why choose our Mn13Cr2 spares?
     Less frequent part replacements mean lower maintenance labor costs and maximum plant uptime for your milling operations.

Split Design for MTW175 Shovel Blades

The MTW175 European Type Grinding Mill incorporates an advanced split-type design for its shovel blades  to maximize cost efficiency:

1. Replace Only the Edge: When the blade wears out, there is no need to throw away the whole shovel base. You only need to replace the worn blade edge.

2. Premium Casting Material: Cast from specialized wear-resistant alloys, ensuring extended durability under high-impact environments.

3. Dual Benefits for Your Plant:

Cuts Wear Parts Costs: Drastically reduces your expenditure on spare parts.

Minimizes Downtime: Fewer maintenance intervals mean your mill spends more time running and less time being repaired.

The Lifeline of Your Grinding Mill: The Lubrication System

The lubrication system is the true lifeline of any grinding mill. Among all maintenance protocols, this is your top priority:

1.Follow the Manual Strictly: Always adhere to the precise guidelines laid out in the Operation and Maintenance (O&M) Manual.

2.Precise Timing & Quantity: Ensure that oil filling, oil changes, flushing, and cleaning are conducted on schedule and with the exact recommended volume.

3.Prevent Unscheduled Downtime: Proper lubrication care is the most effective way to eliminate premature bearing failure and keep your MTW175 mill running smoothly.

Shock Load Protection & Shift Maintenance for MTW175 Mill

Although the MTW175 European Type Grinding Mill is a robust, heavy-duty industrial pulverizer that relies on centrifugal force to grind minerals through particle-on-particle friction, it houses highly sensitive precision components.

1. Avoid Overloading & Shock Impacts:

The internal bearings, precision shafts, and gears can be easily damaged by sudden shocks.

2. Crucial Configuration

A reliable iron remover / magnetic separator must be installed at the front end of the feeding conveyor to intercept harmful metal objects before they enter the mill.

3. Post-Shift Inspection Checklist (Every Shift Shutdown)

1) Check for Loose Fasteners: Open the main mill inspection door. Inspect all internal bolts and tighten them immediately if any loosening is detected to prevent mechanical failure.

2) Clear the Air Plenum/Ducts: Thoroughly check the main air ducts. Ensure the pathways are clear of any material clogging (blocking), and look out for dropped screws, bolts, or tramp iron that could damage the system upon restarting.

A Small Investment That Saves Big Money: Replace Your Shovel Blade Edges On Time!

In the mining and milling business, success often comes down to spending a little to save a lot.Here is how the MTW175 shovel blade edge acts as a small part with a massive impact:

1.The Core Function: The blade edge must efficiently scoop up raw materials and feed them between the grinding roller and ring to create a cushion of material .

2.The Danger of Wear: If the blade edge becomes too worn, it can no longer scoop the material. This forces the rollers and rings into destructive "empty grinding" (dry grinding).

3. The Costly Consequences:

(1) Accelerated Damage: Direct metal-to-metal friction cuts the lifespan of your expensive rollers and rings in half.

(2) Capacity Drop: Your mill's hourly production output will quickly decline.

The Smart Business Move:
Thanks to the MTW175's split-type design, you don't need to change the whole shovel base—just replace the inexpensive blade edge. Changing it regularly is the ultimate way to minimize wear parts costs and maximize your plant’s capacity!

To ensure your milling plant normal runs without unexpected breakdowns, upgrading your critical wear parts is a smart choice:

1. Upgrade to Premium Imported Seals (Premium Sealing Protection):

The Risk: Worn-out or low-grade seals allow fine mineral dust to enter the bearing chamber, leading to overheating and sudden bearing seizure .

Our Solution: We strictly recommend and supply premium, wear-resistant seals made from imported high-quality materials rather than standard domestic options to ensure a bulletproof dust barrier.

2.Quenched & Tempered (Q&T) Shafts – Longer Service Life:

The Material: Our roller shafts and main shafts undergo rigorous quenching and tempering  heat treatment.

The Benefit: This process gives the shafts excellent fatigue resistance, superior flexibility (high toughness), and exceptional wear durability.

The Result: They deliver a service life 3 times longer than that of ordinary steel shafts, protecting your mill from heavy shock impacts.
