CZB Drum Cleaners are efficient and reliable machines designed for the mechanical cleaning of cereal grains and rapeseed. By utilizing the rotary motion of the drum and precisely selected screens, the cleaners effectively separate both light and heavy impurities without damaging the bulk material. High cleaning quality, low energy consumption, and intuitive operation make CZB models widely used in industrial plants, grain collection centers, and agricultural farms.
Minimal mechanical impact on the grain – thanks to gentle and uniform screening, the grain remains undamaged, which is crucial for further storage or processing.
Low motor power and an optimized cleaning process translate into real operational savings – both for smaller farms and large industrial facilities
With a simple latch system, the operator can quickly replace the screens, adjusting the machine to various grain sizes and contamination levels. The machine offers easy internal access without the need for specialized tools.
The combination of screen design and drum rotation ensures excellent separation results for different types of impurities. Proper screen perforation allows for high cleaning quality in just one pass.
The machine is suitable for cleaning various types of grain, including wheat, barley, corn, rapeseed, and rye. It can function as part of a processing line or as a standalone cleaning unit.
The machine is equipped with safety sensors that automatically stop operation in the event of improper cover opening or other hazards. This significantly enhances operator safety.

Operating Principle and Design
The cleaning process is based on the use of centrifugal force – grain is fed into a rotating drum, where it is screened through a set of precisely selected sieves. Their arrangement allows for the separation of both fine impurities (e.g., dust, chaff, broken kernels) and larger foreign materials (e.g., husks, straw, stones). A key advantage of the drum design is that the grain does not slide over the sieves but is evenly distributed across them, reducing the risk of clogging and ensuring high cleaning efficiency.
Drum cleaners are designed to operate both in pre-cleaning and fine-cleaning modes – depending on customer requirements and the configuration of the processing line. The machine’s capacity depends on the model and the type of raw material being cleaned.
Applications
Grain collection centers
Agricultural processing plants
Grain storage facilities
Industrial dryers
Large-scale farms
Additional Technical Information
Optional equipment: discharge auger (for CZB1200 and CZB1600)
Materials: galvanized steel, perforated sieves
Possibility of individual configuration tailored to customer needs
The cleaner uses centrifugal force — the grain enters a rotating drum and is sieved through carefully selected screens. The grain spreads evenly, preventing slipping and clogging of the screens, minimizing mechanical impact and preserving grain integrity
Screen replacement is very easy thanks to the intuitive snap-on system and unrestricted access to the interior of the machine. The operator can efficiently swap screens without the need for specialized tools
The CZB drum cleaners are highly versatile — they can be used for both pre-cleaning and fine cleaning of a wide range of grains (wheat, corn, barley, rye, oats), as well as oilseeds, legumes, or biomass. Thanks to interchangeable screens, they can be easily adjusted to the specific type of raw material.
