Bottom Sieve Insert for Cross Beater Mill, 0.25mm Trapezoidal

Fritsch Cross Beater Mill Bottom Sieve Insert (0.25mm Trapezoidal)

Optimize your milling process and achieve precise particle size reduction with the Fritsch Cross Beater Mill Bottom Sieve Insert. This specific insert features a 0.25mm trapezoidal opening, designed for efficient processing of a wide range of materials.

Purpose and Functionality: Bottom Sieve Inserts are integral components of the Fritsch Cross Beater Mill, playing a crucial role in determining the final fineness of your milled samples. The selection of the correct sieve insert allows for precise control over particle size, with available fineness ranging from 120µm to 10mm, depending on the material's properties and the chosen insert.

Trapezoidal vs. Round Openings:

• Trapezoidal Openings (120µm–10mm): Ideal for faster milling and higher throughput, particularly with medium-hard to soft, fibrous, or tough materials. The unique trapezoidal shape of the perforations minimizes clogging and facilitates a more efficient material flow through the sieve, ensuring consistent particle size distribution.
• Round Openings (3–10mm): Best suited for brittle materials and samples where a more uniform particle size of medium fineness is required. These openings provide a gentler milling action, reducing the risk of over-milling or excessive fine generation.

Key Considerations for Selection: The general rule is that the finer the desired final fineness, the smaller the perforations on the sieve insert should be. Conversely, larger openings will result in faster sample throughput and reduced wear on the sieve itself, making them suitable for preliminary grinding or when coarser particles are acceptable.

Robust Construction: All Fritsch Bottom Sieve Inserts are expertly constructed from high-grade 316L stainless steel. This material choice ensures exceptional durability, excellent corrosion resistance, and a long operational lifespan, even when processing abrasive or chemically aggressive samples.

Features:

• Precision Sizing: Available in a variety of trapezoidal and round openings to achieve precise final fineness (120µm–10mm).
• High Durability: Made from premium 316L stainless steel for extended life and resistance to corrosion.
• Quick & Easy Replacement: Designed for tool-free removal, allowing for rapid changes and efficient workflow in your laboratory.
• Optimized Performance: Trapezoidal design (like this 0.25mm insert) enhances milling speed and reduces clogging for specific material types.
• Versatile Application: Suitable for a broad spectrum of materials, from soft plastics to medium-hard minerals.
