Product Specification

50L Horizontal Disc Sand Mill
Precision Separation, Superior Cooling for Uncompromised Product Quality

1. Product Name: 50L Horizontal Disc Sand Mill

2. Pain Points:

Inefficient Separation: Traditional separation systems can struggle to effectively retain fine grinding media while allowing product to pass, potentially leading to product loss or contamination with larger media.
Contamination Risk from Seals: Standard mechanical seals often require external lubrication (like oil), posing a risk of product contamination and economic loss, especially in sensitive applications.
Inadequate Cooling: Insufficient cooling of the grinding mechanism and cylinder can lead to overheating, affecting product quality, stability, and potentially damaging sensitive materials.
Short Seal Lifespan: Common mechanical seals may have a limited lifespan, leading to frequent replacements and increased downtime.

3. Our Solution:

This series is a classic horizontal sand mill, built on mature, reliable technology and stable performance, with critical advancements in separation and cooling:

Advanced Disc Separation System: We employ a highly efficient interval separation device, consisting of a stationary ring (static ring) and a rotating ring (dynamic ring).

Material Excellence: Both rings are made from premium tungsten carbide, ensuring exceptional wear resistance and durability.
Precision Gap Control: The gap between the static and dynamic rings is precisely adjustable (currently set at 0.17mm for your 200-500nm fineness requirement) based on your target particle size. A smaller gap effectively retains grinding media.
Optimized Media Sizing: The narrow separation gap dictates the use of smaller, highly effective grinding media. We configure our machine with 0.6-0.8mm pure zirconia beads (specific gravity 4.0). This choice ensures excellent media retention, significantly improves grinding fineness, shortens processing time, and boosts productivity.

High-Performance, Contamination-Free Mechanical Seal:

German Import Quality: Our mechanical seals are high-end brands imported from Germany, known for zero leakage and exceptional reliability.
Extended Lifespan: These seals boast a service life exceeding 8,000 hours, minimizing downtime and replacement costs.
Self-Lubricating & Non-Contaminating: Their superior lubricity eliminates the need for external oil lubrication. The circulating fluid is compatible with your product (solvent or water), completely preventing any accidental contamination and associated economic losses.
Comprehensive Cooling System: Equipped with multi-point water cooling for optimal temperature management:

Efficient Heat Dissipation: Cooling is strategically applied to the mechanical seal, the grinding cylinder, the front end plate, and the shaft core (four-point cooling) to effectively dissipate heat generated during grinding.
Ensured Stability: This robust cooling system guarantees sufficient cooling effect, preventing product degradation and maintaining stable operational performance.
Durable & Non-Contaminating Cylinder

Easy Operation

Applicable Scenarios: Ideal for wet grinding of high-viscosity media where achieving ultra-fine particle sizes with absolute purity and consistent cooling is paramount, including:

Paints
Coatings
Inks
Color Pastes
Water-based Pastes
4. Benefits for the Customer:
