Bottom Sieve Insert for Cross Beater Mill, 0.12mm Trapezoidal

Bottom Sieve Insert for Cross Beater Mill, 0.12mm Trapezoidal Holes

The Bottom Sieve Insert for the Fritsch Cross Beater Mill plays a crucial role in sample preparation by controlling the final particle size of the ground material. This particular insert features 0.12mm (120µm) trapezoidal perforations, making it ideal for achieving a very fine final particle size.

Function and Application: Bottom Sieve Inserts are interchangeable components that fit into the base of the Cross Beater Mill's grinding chamber. As the rotor pulverizes the sample, only particles fine enough to pass through the sieve's openings can exit into the collecting pan. The size and shape of these openings directly determine the final fineness of the sample.

• Trapezoidal vs. Round Holes: Sieve inserts are available with either trapezoidal or round perforations.
  • Trapezoidal perforations (like this 0.12mm insert) are best suited for fibrous, soft, or medium-hard materials. The shape of the holes promotes faster milling and higher throughput.
  • Round perforations are typically used for brittle materials, yielding a more uniform particle shape and size distribution.

The choice of sieve insert is critical for reproducible results. Generally, smaller perforations are required for finer grinding, but this may increase processing time and heat generation. Larger perforations allow for faster throughput and are suitable for pre-crushing or when a coarser final product is acceptable.

All sieve inserts are designed for quick, tool-free installation and removal, allowing for efficient workflow changes and easy cleaning between samples to prevent cross-contamination.
