Pin Breaker

At Klinkenberg, we understand how crucial it is for bulk materials to be free from lumps and hard agglomerates. That’s why we’ve developed our own range of lump breakers that use breaker pins to efficiently reduce coarse materials. Thanks to our pin breaker technology, any product can be reduced to a manageable size of 10 to 15 mm.

Efficient reduction of coarse lumps

The Pin Breakers — or Lump Breakers — from Klinkenberg are designed to reduce coarse, difficult-to-handle bulk materials into more manageable agglomerates of 10 to 15 mm. To achieve this, Klinkenberg Lump Breakers use powerful pulverization technology, making them highly effective across a wide range of products.

Other types of breakers we offer include Knife Lump Breakers and Sweeper Lump Breakers — a complete range of tools for breaking down large, hard lumps for easier handling and processing of bulk materials.

The Pin Breaker is designed to pulverize semi-hard agglomerates, coarse particles, and lumps in bulk materials, including chemical powders, food ingredients, and pharmaceutical substances.

A single-shaft Pin Breaker has one rotating shaft with pins and is suitable for less demanding applications. A double-shaft version has two parallel rotating shafts, offering more power for harder and larger lumps.

Yes, the Pin Breaker can be designed according to ATEX guidelines for use in explosive environments, with spark-proof materials and explosion relief provisions.

This depends on the specific configuration, but typically lumps and agglomerates up to 100 mm in diameter can be reduced. After processing, particle sizes range from 15 to 20 mm or smaller, depending on the breaker inlet size.

The pins can be made from wear-resistant materials such as hardened steel or tungsten carbide, and optionally coated to extend service life.

Yes, the Pin Breaker can be easily integrated with other systems such as Dosing Screws, vibrating screens, and conveyors, depending on process requirements.

The Pin Breaker can be driven by an electric motor with direct drive or via a gearbox for controlled power transmission.

Yes, the breaking capacity can be optimized by adjusting the rotation speed, pin spacing, and feed control.

The breaker can be equipped with variable speed and an automatic reverse function to minimize blockages. Additionally, self-cleaning pins can help dislodge sticky material.

By default, the Pin Breaker is designed for dry materials, but it can be adapted for slightly moist or hygroscopic products using special materials and coatings.
