Product Overview
The sealed laboratory sample pulverizer is a new-generation sample-preparation machine developed for grinding metallic and non-metallic materials with a certain degree of hardness. Typical materials include coal, ore, cement, chemical products and hard traditional medicines. It is widely used in laboratories serving the coal, metallurgy, mining, power, building-material, chemical, pharmaceutical and scientific-research sectors. Stable operation, reliable safety, a long service life and rapid processing help shorten the sample-preparation workflow. Grinding takes place inside a sealed assembly, preventing dust contamination and minimizing sample loss. Installation and operation are straightforward, and screening or sample division is generally unnecessary.
How It Works
Key Advantages
Double sealing at the grinding bowl and machine chamber prevents dust escape, reduces sample loss and helps eliminate cross-contamination. No separate dust collector is required, supporting laboratory environmental and safety requirements.
A timer allows the grinding duration to be preset and stops the machine automatically when the cycle is complete. A compression-locking mechanism keeps the bowl secure, while rubber vibration isolation provides smooth, low-noise operation and prevents machine movement.
Grinding bowls are available in high-manganese alloy steel, tungsten carbide, zirconia and other wear-resistant materials for samples of different hardness. Smooth internal surfaces simplify cleaning, and quick bowl removal makes sample changes easier while reducing residue interference.
A copper-wound vibration motor provides stable and durable power. The compact machine is easy to inspect and maintain, requires no anchor bolts and can be placed directly in a laboratory workspace.
