Crushers and Shakers Digest Catalog 2025 Edition

An evolved all-rounder for fine/low-quantity grinding.

Main New Features ■ Grinding time setting of up to 99 hours (previously a maximum of 99 minutes) ■ Easy operation with a touch display ■ Calibration capability ensures reproducible results (calibration of time and frequency) ■ New transparent PMMA grinding jar allows for in-situ spectroscopic experimental methods ■ Reduced noise levels during equipment operation ■ Ability to register 12 SOPs (Standard Operating Procedures) and 8 programmed grinding cycles ■ Front cover features a damper for smooth opening and closing operation

A planetary ball mill for sample grinding that powerfully and quickly crushes down to the nanoscale.

Powerful and rapid grinding down to the nano range Benchtop model with two turntables compatible with grinding jars from 12ml to 125ml The Retsch planetary ball mill is suitable for ultra-fine grinding. It can perform not only conventional mixing and grinding but also colloidal grinding and mechanical alloying. The planetary ball mill has a powerful grinding force due to the combination of two centrifugal forces: revolution and rotation, significantly reducing grinding time. The planetary ball mill can grind and mix samples that are soft, hard, brittle, and fibrous, and it is suitable for both dry and wet grinding. Easily, quickly, and without loss, it can grind minerals, ores, metal compounds, chemicals, glass, ceramics, plants, soil, sludge, and household and industrial waste. 【Features】 ■ Larger effective revolution diameter compared to PM100, providing greater grinding power ■ Capable of grinding down to sub-micron levels at high rotation speeds ■ Suitable for long hours of continuous use ■ Reverse function to reduce agglomeration ■ Stable rotation for highly reproducible grinding results ■ Condition input is interactive while viewing the LCD screen (displayed in Japanese) ■ Automatic ventilation for the grinding chamber ■ CE mark indicating compliance with European safety standards

Gummy candies and dried fruits are also uniformly frozen and crushed. The operability is good with a 4.3-inch touch panel.

【Other Features】 ◎ The standard deviation of the sample analysis results is about one-tenth compared to household blenders. ◎ All knives, containers, etc., are fully disassemblable for cleaning. ◎ Equipped with a safety cover and limit switch. * A wide variety of accessories are also available. Please refer to the materials for more details. Feel free to contact us with any inquiries.

Food analysis requires uniform and highly representative sample preparation. This is an ideal physicochemical mixer for producing representative samples that are important in food analysis.

This is a grinder that homogenizes samples in a short time of about 30 seconds with high reproducibility. ◆ Achieves both preliminary crushing and fine grinding with one machine It allows for the differentiation between preliminary crushing using the back (ridge) of the rotating blade and fine grinding using the blade surface. ◆ Equipped with a powerful industrial motor The rotation speed can be adjusted to accommodate various applications. ◆ Digital display allows registration of up to three grinding conditions High reproducibility can be achieved with simple operation. ◆ Parts that come into contact with the sample can be easily attached and detached without tools Excellent cleanability helps avoid cross-contamination. ◆ A wide variety of accessories such as containers and lids Containers are available in polycarbonate, polypropylene, stainless steel, and glass. Additionally, the gravity lid sinks under its own weight according to the volume of the sample, allowing for efficient grinding of vegetables and other materials that significantly reduce in volume during grinding.
