Specification for Use of 24~46Mesh Iron Pyrite
Exclusive Application: Low‑speed polishing products (polishing pads, polishing wheels, hemp wheels, cloth wheels)
Strictly Prohibited: All high‑speed cutting abrasive wheels (cut‑off wheels, angle grinder discs, grinding discs, depressed‑center wheels, resin‑bonded wheels, vitrified wheels)
Scope of Application (Only Safe Uses)
Industrial polishing wheels (cloth wheels, hemp wheels, non‑woven polishing pads)
For coarse polishing, wire drawing, deburring, and oxide‑scale removal on surfaces of stainless steel, copper, aluminum, alloys, stone, etc.
Coarse stone grinding wheels (for marble, granite)
For rapid surface leveling, coarse grinding, and defect removal on stone surfaces.
Scope of Prohibition (Absolutely Forbidden)
All high‑speed rotating cutting abrasive wheels (rotational speed > 2000 rpm)
Cut‑off wheels, angle grinder discs, grinding discs, depressed‑center wheels, resin‑bonded wheels, vitrified wheels
Any grinding, cutting, or abrading products
Safety Reasons (Core Basis)
Coarse particles (0.35–0.7 mm) with high brittleness → prone to cracking, flying fragments, and injury at high speeds
Decomposes at high temperatures → generates toxic gases (SO₂, H₂S)
Insufficient strength → unstable abrasive wheel structure, risk of bursting
Conditions of Use (Must Be Followed)
Limited to low‑speed equipment (rotational speed < 1500 rpm)
Limited to polishing/coarse grinding; no cutting function
Must be marked: For low‑speed polishing only; high‑speed cutting is prohibited.
