Rotary Drum Cleaner

Trevor Ellis — Thu, 12 Feb 2026 10:50:22 +0000

When raw material is delivered to the storage facilities in a damp or soiled condition then cleaning is essential in order to prepare the product for further processing and storage. PETKUS Rotary Drum Cleaners separate foreign particles or coarse impurities from fine and coarse-grained products thoroughly and reliably. The drum cleaner is available in two models with a coarse cleaning performance for corn between 50 t/h and 75 t/h, and for wheat between 70 t/h and 100 t/h.

A weighted inlet flap distributes the product perfectly over the entire working surface even in the case of fluctuating throughput rates and product changes. The product flows through a rotating screen drum where coarse rejects are separated and discharged on the periphery of the screen drum.

Characteristics

Suitable for coarse cleaning of even moist products
High throughput rate
Relief of the following cleaners and dryers
Design, reliable and low-maintenance
Bolted housing made of galvanized sheet steel

Calibrating Machine

Trevor Ellis — Thu, 12 Feb 2026 10:50:22 +0000

Calibrations in different grain sizes and shapes are an essential part of the seed cleaning process. Sorting according to different calibers must be done very carefully in order to protect and enhance seed quality.

PETKUS Calibrating Systems provide for a precise sorting of the required calibers and are variable with regard to the number of calibers whereby up to five different calibers can be sorted in one screening. PETKUS offers a wide and variable range of different hole sizes for slotted and round-hole screens.

Characteristics

Low specific screen load due to two screen compartments and up to six screen layers and a working width of up to 1500 mm
Up to five different calibers in one screening process, depending on machine type
Variable infeed system for handling several different products
Proven ball cleaning method minimizes the danger of clogging by equally dispersing the material over the entire working surface
Efficient inlet dust removal

PETKUS Process Machines Type SM allow for the coarse and pre-cleaning of dry, granular and free flowing products for the use in industrial grain processing companies. They are available in different models, with capacities ranging from 35t/h to 120 t/h and screening surfaces from 3.1m² to 10.45 m². Machines with four screen layers have two top screens and two bottom screens working parallel. The product is divided equally at the infeed and in connection with the extensive setting options for the height of stroke; the angle of throw and the screen inclination the cleaning performance is very high. Ideally used in mills and malting plants, the high standard of cleaning as well as easy and quick screen change allow for user friendly, low maintenance, continuous use.

Characteristics

Feeding with dispersion saddles and guiding units
One screen compartment, two or four screen layers with different working surfaces of 900 mm, 1200 mm or 150 mm
High standard of cleaning
Simple and quick changing of screens
Stroke, angle of throw and screen inclination can be adjusted
Proven ball cleaning method minimizes clogging
Reliable and low-maintenance
Bolted housing made of galvanized sheet steel
Drive unit with vibratory motors
