Multifunctional Mortar Grinder: A Precise, Contamination-Free Solution for Sample Grinding and Homogenization

DESCRIPTION / TECHNICAL SPECIFICATIONS

Universal Multi-Functional Mortar Grinder Solution for Precision Sample Pulverizing, Homogenization, and Anti-Contamination Mixing

In industrial quality control (QC) laboratories, R&D centers, and raw material inspection facilities, achieving uniform particle size reduction while preventing cross-contamination is critical for reliable analytical results. This Multi-functional Mortar Grinder is a universal grinding, pulverizing, and sample homogenization instrument engineered to mix and grind soft, hard, brittle, sticky, paste-like, and moist samples. Designed for exceptional versatility, it seamlessly supports dry grinding, wet grinding, and cryogenic grinding within a single compact benchtop unit.

Core Function and Friction-Extrusion Working Principle

Operating on the mechanical principle of friction and extrusion, the sample enters the mortar through the top feed port and is continuously squeezed and rubbed between the rotating mortar and the pestle. Both the position and pressure of the pestle can be precisely adjusted according to different sample properties. Simultaneously, under the action of the shovel head (scraper), the material is repeatedly squeezed, rubbed, and mixed to achieve thorough sample homogenization.

Accepting an initial feed size of <10 mm with a batch processing capacity of 10 to 230 ml, this mortar grinder achieves an ultra-fine output size of <2 µm (depending on sample characteristics).

Industrial and Laboratory Applications

To prevent sample contamination during the grinding process, multiple anti-contamination grinding kits are available in seven different materials—including quartz, stainless steel, hard steel, tungsten carbide, zirconia, corundum, and hard porcelain. This makes the instrument ideally suited for a wide spectrum of industries:

• Mining, Geology, and Construction Materials: Pulverizing soil, coal, coke, rock minerals, glass, construction raw materials, and cement.
• Pharmaceuticals and Botanicals: Contamination-free grinding and homogenization of medicines and plant tissues.
• Food Processing and Agriculture: Mixing and grinding agricultural products, food samples, and spices.
• Ceramics and Advanced Materials: Preparing ultra-fine powders for ceramic and material science testing.

Key Technical Features and Operational Advantages

Engineered for repeatability, operator convenience, and safety, this Multi-functional Mortar Grinder incorporates 11 advanced technical features:

1. LCD Touch Screen Operation: Features an intuitive LCD touch screen with real-time load change display and memory capacity for 10 storage programs.
2. Graduated Pestle Pressure Display: Allows pestle pressure to be adjusted at any time with a graduated scale, ensuring highly repeatable grinding results across batches.
3. Adjustable Scraper and Pestle Positions: Easily configurable to meet diverse experimental and material processing requirements.
4. Triple Grinding Mode Compatibility: Fully suitable for dry grinding, wet grinding, and cryogenic grinding applications.
5. Intermittent Mode for Heat-Sensitive Samples: Includes a programmable intermittent operating mode ideal for grinding thermally sensitive materials without degradation.
6. Safety Door Control Device: Automatically stops instrument operation immediately when the protective cover is opened.
7. Seven Anti-Contamination Grinding Kit Options: Selectable mortar and pestle materials prevent unwanted elemental contamination.
8. Tool-Free Plug-and-Pull Design: The mortar and pestle adopt a convenient plug-and-pull structure for quick removal, installation, and cleaning.
9. In-Process Sample Addition: Allows operators to increase sample quantity or add liquid/cryogenic agents directly through the feed window during grinding.
10. Integrated Chamber Lighting Function: Illuminates the grinding chamber to facilitate accurate adjustment of the pestle and scraper positions as well as visual observation of the grinding process.
11. High-Torque, Silent Deceleration Motor: Delivers low-noise operation combined with high output energy for tough grinding tasks.
