Special Applications of -325 Mesh Pyrite Ore Powder
Main Types of Grinding Wheels for Application
Resin cutting discs/grinding wheels (dry cutting of metals, stainless steel, steel rails, section steel, and steel bars)
Resin rough grinding wheels (for high‑strength, dry‑grinding conditions)
Resin grinding/angle grinding wheels (for metal surface grinding and deburring)
Four Core Functions
Chemical Lubrication & Grinding Assistance
Releases active sulfur at high temperatures during grinding, forming a sulfide lubricating film on the metal surface to reduce friction, prevent adhesion, and improve cutting/grinding efficiency.
Cooling & Heat Dissipation + Protection of Resin Binder
Absorbs heat through thermal decomposition, lowering the temperature in the grinding zone and preventing softening or ablation of the resin binder. The superfine powder disperses uniformly, ensuring stable heat dissipation and avoiding local overheating and failure of the grinding wheel.
Structural Reinforcement + Extended Service Life
Fills the pores of the grinding wheel to enhance density, hardness, strength, and wear resistance; reduces abrasive grain detachment, making the wheel more durable.
Assisted Self‑Sharpening + Improved Surface Quality
Promotes moderate consumption of the binder to keep abrasive grains sharp; reduces scratches and burns on the workpiece, improving surface finish.
