Lump breaker with sieve disc

Components

Description

A lump breaker with sieve disc is an industrial grinding unit that mechanically breaks down lumps, agglomerates and cakes in powders and granules to a uniform particle size. HECHT lump breakers comply with GMP Annex 1 (2022), ATEX 2014/34/EU and can be used for OEB 1–4 containment applications in pharmaceuticals, chemicals and food.

Customer benefits

  • Hygienic design construction
  • Quick to dismantle and easy to clean
  • The sieve insert is easy to replace and available in different mesh sizes (10, 15 or 20 mm)
  • The distance between the sieve and rotor can be adjusted and thus adapted to the respective product
  • Capacity of up to 1,000 - 4,000 kg/h (depending on product)
  • Pharmaceutical-grade O-ring seal on the door
  • Storage air flushing (also possible with nitrogen)
  • Foreign body and temperature monitoring with optional automatic decoupling or switch-off
  • A safety switch prevents accidental opening of the door
  • Suitable for Ex zones 20 to 22

Frequently asked questions about the lump breaker with sieve disc

What is a lump breaker and why is it needed in industrial processing?

A lump breaker is a grinding unit that mechanically breaks down lumps, agglomerates and cakes in powders/granules to a uniform particle size. It is essential because agglomerates cause blockages in transfer lines, dosing systems and downstream equipment. The HECHT lump breaker guarantees consistent, homogeneous product throughput for reliable processes.

What capacity does the HECHT lump breaker have and what determines this?

Capacity is 1,000–4,000 kg/h and is determined by: (1) product type (viscosity, density), (2) sieve mesh size (10/15/20 mm), (3) rotor-stator distance, (4) rotation speed. HECHT advises based on a process simulation for your specific product.

Does the lump breaker comply with GMP and ATEX?

Yes. HECHT lump breakers are GMP Annex 1 (2022) compliant with hygienic design (smooth, corrosion-resistant stainless steel surfaces), quick to dismantle for CIP. ATEX variants are available for zone 20–22 explosive dust environments with full certification per Directive 2014/34/EU.

How easy is it to replace the sieve insert?

The sieve insert is designed for quick exchange without tools. Available mesh sizes are 10, 15 and 20 mm. Replacement takes <5 minutes. This allows operators to quickly switch between products or address wear.

What happens to material that doesn't pass through the sieve?

Material that isn't small enough remains in the crushing chamber and is ground again until it passes through the sieve. This "recycle principle" guarantees that all product meets the required particle size before leaving the system.

Can the lump breaker detect foreign objects?

Yes. HECHT offers optional automatic foreign object detection via current monitoring and temperature sensors. Upon detection, the system can automatically decouple or shut down for safety and product integrity.

How is the lump breaker cleaned?

The hygienic design makes manual cleaning easy. Quick-release fastenings allow removal of the rotor/stator unit. For automated cleaning, CIP connections can be installed. Bearing flushing can use water or nitrogen per GMP requirements.

Which types of powders can be processed by the lump breaker?

Suitable for: pharmaceutical APIs, excipients, chemical fine powders, food ingredients, battery materials. HECHT advises based on product properties (viscosity, abrasiveness, density, moisture content).

Technology

Crusher with screen – optimization of product feed and lump handling

The HECHT Technologie crusher with screen is a robust process component designed to efficiently reduce the size of clumpy, agglomerating products so that they can be reliably and controllably transported through subsequent processes.

Technical Operation

  • Agglomerate Breakup Using the Rotor-Stator Principle
    The “agglomerated” material is mechanically broken up by the interaction of a stationary stator and a rotating rotor, causing the product streams to be intensively mixed and forced through the screen opening.

  • Selective single-pass screening
    The screen with a specific mesh size ensures that only material that has been sufficiently reduced in size passes on to the next process. Larger pieces are retained and are re-ground until the desired particle size is achieved.

  • Continuous Process Integration
    By combining crushing and screening, the system ensures a constant, uniform product feed to downstream equipment such as conveyor units, mixers, or dosing systems.

Benefits for Industrial Applications

✔️ Improved downstream efficiency
A consistent particle size prevents clogging and uneven feed into conveying systems or mixers.

✔️ Higher product quality
Through effective agglomerate stabilization, this product reduces variation and supports process reliability.

✔️ Compatible with industry standards
Designed for integration into advanced process and bulk material systems, where operational stability and reliability are essential.

Areas of Application

This crusher with screen is particularly suitable for use in sectors such as:

  • Pharmaceutical manufacturing – processing of active pharmaceutical ingredients (APIs) and raw materials.
  • Chemical industry – handling of substances prone to agglomeration.
  • Food and high-tech powder processing – where precision and reproducibility are crucial.

Integration into production lines

The crusher with screen can be part of a fully enclosed processing line, integrated with HECHT’s pneumatic conveying and dosing systems, such as the ProClean Conveyor (PCC) or dosing valves, for safe, low-dust processing under demanding process requirements.
