The HTZY Sealed Sample Grinders are primarily used for pulverizing raw materials (e.g., coal, coke, gangue, ores) into fine powders for laboratory testing.

• Working Principle: Vibration grinding
• Feed Particle Size: <13 mm
• Material Compressive Strength: ≤800 kg/cm²

Designed with a compact structure, easy maintenance, and user-friendly operation, these grinders are widely applied in industries such as construction, metallurgy, mining, coal, coking, chemicals, and non-ferrous metal smelting for sample preparation.

Working Principle & Structural Features:

The grinder consists of:

1. Housing: Cold-rolled steel enclosure for sealing, safety, and aesthetics.
2. Base: Cast from high-quality damping materials to minimize vibration during operation.
3. Damping System:
   1. High-performance springs (high strength, elasticity) + rubber pads for dual damping, reducing noise and ensuring stability.
4. Power Unit:
   1. Motor, eccentric weight, and support cylinder.
   1. The motor drives the eccentric weight to generate high-speed orbital motion, transmitted to the grinding assembly.
5. Grinding Assembly:
   1. Grinding bowl, ring, and hammer.
   1. Materials are crushed and ground into fine powder via high-frequency impact.
6. Clamping Device:
   1. Lever and screw mechanism to secure grinding components for efficient power transfer and safety.
