Fritsch Cross Beater Mill, Stainless Steel

Fritsch Cross Beater Mill, Stainless Steel: Precision Grinding for Diverse Applications

The Fritsch Cross Beater Mill stands as a robust and highly efficient solution for the pre-crushing and fine grinding of a wide array of materials. Designed to handle medium-hard, brittle substances with a Mohs hardness of up to 6, this versatile mill is equally adept at processing softer materials such as grains, seeds, dried plant matter, and various resins. Its broad applicability makes it an indispensable tool across numerous sectors, including agriculture, forestry, geology, mineralogy, mining, ceramics, plastics, textiles, metallurgy, and the production of construction materials.

Advanced Grinding Mechanism At the core of the Cross Beater Mill's performance is its dynamic reduction principle, utilizing a combination of impact, friction, and shearing forces. Material introduced via the feeding funnel is directed into the grinding chamber, where it is subjected to intensive comminution between the rotating impact plates of the cross beater and the stationary teeth of the grinding insert. This ensures thorough and rapid size reduction. The mill accommodates a maximum feed size of up to 25mm and boasts an impressive maximum throughput capacity of 80 liters per hour.

Optimized Fineness and Sieve Options Achieving precise final fineness is paramount, and this mill delivers with a range from 120µm to 10mm, depending on the specific material and the chosen bottom sieve insert. Two distinct types of sieve inserts are available:

• Trapezoidal Sieve Inserts: Featuring openings from 120µm to 10mm, these are engineered for faster milling processes, particularly with medium-hard to softer materials, optimizing sample throughput.
• Round Sieve Inserts: Available with openings from 3mm to 10mm, these are ideal for processing brittle materials where a medium fineness and uniform particle size distribution are critical.

Robust Construction and Safety Features Powered by a durable 1.1kW 3-phase motor, the Fritsch Cross Beater Mill includes integrated overload protection for continuous and reliable operation. Safety is a priority, with a built-in safety switch that instantly halts the rotor if the quick-clamping lock is inadvertently opened, preventing access to moving parts during operation. The unit operates on standard 200–240V, 50/60Hz electrical supply.

Material Configurations:

This premium variant includes a grinding insert, cross beater, and impact plates all constructed from high-grade stainless steel. The stainless steel composition provides superior corrosion resistance and makes it particularly suitable for applications requiring stringent hygiene standards, such as in food processing, pharmaceuticals, or when handling aggressive chemical samples.

Comprehensive Package: Each Fritsch Cross Beater Mill includes the grinding insert, the cross beater, impact plates, and a 5-liter collecting vessel equipped with a filter hose for efficient sample collection. Please note: A Bottom Sieve Insert must be ordered separately to customize the final particle size.

Key Applications:

• Agriculture: Preparation of grains, seeds, and dried plants for quality control, moisture content, or compositional analysis.
