GS Centrifugal Sifters

Centrifugal Sifter

Gericke has provided centrifugal Sifting solutions to the solids and powder handling industry for over 50 years. Our sifters are specifically designed to meet the increasing demands of modern applications and processes. 

The machine range, sizes, features and configurations can be optimised for a wide variety of sifting applications.

Gericke sifters are widely used to increase throughput, improve efficiency and maximise profitability of new and existing processing lines. 

The Gericke centrifugal sifter is designed to separate particles of different sizes into two product streams and to remove tramp and oversize materials.

The rotation of the paddles continually moves the product along the basket presenting material to the sieve hose, this centrifugal action make rotary sifters the most suitable equipment for high efficiency and high capacity product screening and classification.

Gericke Sifters are an evolution of a design classic.

Whilst the principle of centrifugal sifting has remained constant, the demands of modern processes are ever increasing. 

Remaining one-step ahead of these demands requires a sifting machine that provides time-proven application technology, yet allows for rapid inspection, cleaning, change-over, repeatability, access and maintenance. All of which combine to minimise down-time, increase yield and maximise productivity.



Time delay interlock ensures operator safety. Balanced hinged door for single hand operation and access.Basket and screen can be rotated fully within the machine casing, allowing ease of inspection and reduced maintenance timeframes.

The new range of Gericke sifters provides increased service and maintenance access via large removal covers with single point captive fixing.
Basket location points and robust fixing studs ensure the basket & screen assembly is returned to the optimum position every time.

Sifter range

Gericke sifters are available in four variants GS722, GS1022, GS1130 and GS1542.
All variants are available in Carbon steel, 304 stainless, or 316 stainless steel with a number of surface finish options to suit your particular application.

Each sifter can be individually configured using a range of features and options designed to tailor the machine to your requirements to suit almost any sifting duty.

Principle of Centrifugal Sifting

The primary function of Centrifugal sifter is to separate particle sizes of differing sizes in to two streams.

Sifter Applications

To guarantee product quality within processing powder, granular and fibrous materials.

Gericke centrifugal sifters provide three main operational processes:

  1. Particle separation: To separate products with a varying particle size into two fractions, typically within the range of 40µm to 5mm.  
  2. Safety sifting: removal of foreign parts and tramp material prior to product entering a production process, or to secure product quality before filling.
  3. Conditioning: To separate foreign bodies and condition the product bulk density prior to production or immediately before packing.

Gericke sifters have been designed and developed for the optimization of these sifting tasks. The basic principles of centrifugal sifting, provides high level performance and optimum separation with a minimal footprint.

Sifting capacities from; 2-3kg/hour guaranteeing product quality of high value small batch operations, up  to 120t/hour minimising the time-frame for filling of road tankers, a preferred method utilized throughout the milling industry and the production and processing of sugar and starch.
