2000cc Laboratory Pulverizer Mill Grinding Dis Durable Casting Services Product

In laboratory sample preparation and material analysis, the 2000cc laboratory pulverizer mill represents essential equipment for consistent particle size reduction. The grinding disc, as the core component of these systems, requires exceptional durability, wear resistance, and geometric precision to ensure reproducible results across countless grinding cycles.

Advanced Material Selection and Properties
Our grinding disc casting services utilize specialized wear-resistant materials, primarily high-chromium cast iron (BTMCr20) and alloy tool steels, engineered to withstand the abrasive nature of various sample materials. These alloys demonstrate:

• Surface hardness: 58-65 HRC

• Impact toughness: ≥15 J/cm²

• Abrasion resistance: 3-5 times superior to conventional steel

• Compressive strength: ≥1500 MPa

The high-chromium content (18-22%) forms hard carbides within the martensitic matrix, creating a microstructure that resists both abrasive wear and impact fatigue. This material combination ensures extended service life while maintaining consistent grinding performance throughout the disc's operational lifespan.

Precision Manufacturing Process
The production of these critical components follows a rigorous manufacturing protocol:

1. Pattern Design & Tooling: CAD-engineered patterns accounting for solidification shrinkage and machining allowances

2. Shell Molding Process: Ceramic shell investment casting using zircon-based refractories for superior surface finish

3. Controlled Pouring: Vacuum-assisted casting in controlled atmosphere furnaces at 1580-1650°C

4. Heat Treatment: Multi-stage thermal processing including stress relief annealing, quenching, and double tempering

5. Precision Machining: CNC grinding of critical surfaces and grinding features to maintain dimensional accuracy within ±0.1mm
