Wear Flow package is an easy way to order new wear parts.
It is a machine-specific offering for parts which wear out, available for YNM60,YNM80, YNM100L, YNM125 and YNMM1250-5 ultra-fine ring roller mills.
1\ Ensure best performance for your mill.
2\ Maximize production time by reducing unplanned stoppages.
3\ High availability through our global service network.
Product Overview
1、GRINDING ROLLER SPARES

Standard, Premium and Heavy-Duty wear parts for YNM grinding rollers
1- They provide extended wear life and optimized grinding performance.
The three-grade grinding roller series lifts your milling performance.
They provide extended service life, lower cost per ton, and optimized grinding capacity and powder uniformity.
2- They are suitable for every type of mineral and chemical powder application.
Tips: Through our Grinding Cavity Optimization services, we offer customized solutions to find the optimal roller material and profile that improve your grinding performance and lower cost per ton even further
2、GRINDING RING SPARES

Matched wear rings for stable grinding gap consistency
Especially engineered for matching with YNM grinding rollers
1- grinding ring spare parts are designed to maintain precise grinding gap throughout the service cycle.
You can rely on the OEM-grade grinding rings to be the backbone of consistent powder fineness.
2- Known for uniform wear, reduced fineness fluctuation and safe long-term operation
grinding rings match your choice.
Spesific Upgrades: Main material options
1\ Forged Alloy Steel
2\ Forged Bearing Steel
3\ Cast High Chromium Alloy
3、SHAFT PINS

Heavy-load connecting shaft pin spare parts for YNM grinding roller assemblies
1- Engineered to withstand long-term alternating impact loads inside the mill.
shaft pins are precision machined spare parts built for the most demanding continuous grinding production.
2- Known for high tensile strength, strong wear resistance and low fracture risk.
3- shaft pins are your ideal choice
whether you need direct replacement for worn pins or an upgrade for high-abrasive raw material processing.
Spesific Upgrades: Main material options
1\ Standard alloy steel shaft pins
2\ Premium bearing steel shaft pins
4、 TURN PLATES

Wear-resistant rotary tray spare parts for YNM grinding chamber material bearing
Standard and composite turn plate wear parts for all YNM ring roller mills.
1- Turn plates greatly lower the frequency of mill maintenance.
2- Turn plates upgrade your whole grinding system stability.
They provide powerful anti-scouring performance, reduce abnormal vibration and cut your per-ton operation cost.
3- They fit all YNM models.
Through our Grinding Cavity Optimization services, we can match the most suitable turn plate structure according to your raw material abrasion level, further extending component service cycle and improving overall milling efficiency.
Spesific Upgrades:Main structure types
1\ Integral cast steel turn plate
2\ Composite welded turn plate
Tips: All worn turn plates need overall replacement upon reaching wear limit.
5、Classifier

Full-range structural and auxiliary spare parts
Beyond core wear parts, we offer a complete portfolio of auxiliary components for HGM series mills.
1- Ensuring seamless compatibility
All parts are manufactured to original equipment dimensions for direct drop-in replacement.
Supporting the long-term reliable operation of your complete milling system.
