These are manufactured to internationally recognised quality assurance standards and are checked and certified for compliance to BS 410. Each is issued with a unique serial number and a Conformance certificate for full product traceability.
Labtech Essa specialise in sieves of stainless or plated steel construction that are inherently more robust, durable and corrosion and corrosion resistant than traditional brass sieves.
Labtech Essa sieves are manufactured to metric dimensions and will interchange with other metric frames. Adaptors are available for customers needing to interchange with older imperial dimension sieves or US made sieves. |

Retsch sieve shakers are used in research & development, quality control of raw materials, intermediate products and end products, and in production control. The AS 200 series enables every user to select a suitable device according to his individual requirements, profile and budget. The AS 200 control meets the highest standards in quality assurance and offers a microprocessor-controlled measuring and control system, patented and unique throughout the world, for constant vibration. It can be calibrated, and ensures for the first time 100% reproducibility of sieving results, and not only for one device, but all AS 200 control units one to another. This provides the prerequisite for monitoring inspection, measuring and test equipment according to ISO 9000.
Further models: AS 300 control, AS 400 control |

An electro-mechanical shaker for suspended mounting and carrying up to two off 450mm diameter standard test sieves
This unique shaker is specifically designed to be fitted with up to two off 450mm diameter test sieves of any aperture. Drive is by a special 240V, 50hz single phase electric motor to a rotating eccentric mass assembly that causes the sieves to oscillate in a mainly horizontal plain.
It is supplied as standard to process essentially dry materials but a wet sieving option is available. The shaker can be suspended from any suitably robust hook.
An optional wheel mounted stand with a manual winch is available to suspend the sieve stack at a maximum height equivalent to a 220 litre drum. The sieve stack can be lowered to floor level. |

For many years now, the technically highly developed original Allgaier tumbler screening machines set the standard for fine and ultra-fine screening of all types of bulk goods. The successful TSM series has now been supplemented by the tsi series with improved design but additional machines sizes.
With the development of the world's largest tumbler screening machine tsi 290 and some related, patented innovations such as segmented screen inserts, Allgaier has extended their technological lead even further. |

Vibrowest tumbler screening separator is used for control screening, fractionating and dedusting of dry, powdered and granular products.
The tumbler screening machine has a three-dimensional movement similar to the simple hand screening of the "gold washing pan". It involves a better efficiency and an higher specific screen load compared to vibration system.
It is used in all sectors of application and has stable screen motion even under full load. Particularly suitable for high feed rates and multi deck separations of fine, lightweight products which are difficult to screen.
Tumbling movement easy regulation and low frequency vibrations guarantee the following advantages:
- no particle destruction in sensitive products
- precise control of product residence time on the screen
- screening efficiency up to 99%
- constant product quality
Easy to install, can separate particles in 1 to 6 sizes with up to 5 screen decks incorporated in one Vibrowest separator.
Standard model range in diameter size from 1.200 mm to 2.600 mm
Screens are easy and fast to change and can be equipped with various cleaning system as: rubber balls, rotating plastic roller brush and the innovative ultrasonic cleaning system.
The separator can be built on customer request with carbon steel, stainless steel AISI 304, stainless steel AISI 316.
On request: ATEX certification, FDA IQ-OQ procedure, GMP
Main sectors of application:
- Food industry
- Dairy farming
- Chemical
- Pharmaceutical
- Recycling and environmental
- Plastic materials
- Agriculture
- Confectionary industry
- Cement and sand
- Metal processing industry
- Wood industry |

With the aid of the Allgaier ultrasonics, it is possible to overcome the high adhesive forces between the particles. Allgaier opens the way to higher throughputs and screening efficiency, even for materials which are difficult to screen.
You can use the ultrasonics for large screening machines with diameters up to 2,900 mm. |

Vibrowest turbosonic system allows separations of light powders with meshes ranging from 0,250 mm to 0,025 mm (25 micron).
Some powders, due to their granulometry, light bulk density and physical features, can not be sieved only with the mechanical movement of the separator. The turbosonic system allows the sieving thanks to the creation of an additional ultrasonic frequency vibration straight on the wire of the sieving mesh.
ADVANTAGES
Productivity:
better sieving results are reached combining mechanical and ultrasonic vibrations.
Performance:
higher throughputs and screening efficiency, even for materials which are difficult to screen.
Maintenance:
prevent blinding of fine mesh, keep constantly clean the screening surface and avoid screen clogging;
guarantee a longer screen life.
Set Up
The automatic frequency control selects automatically the right frequency for the mesh. |

Screening machines of the VTS series are suitable for the economical processing of almost all bulk solids with fine to medium and coarse grains.
The VTS is also ideal for screening of wet materials. The vibrating motion can be adjusted to match the required screening quality and the throughput. |
|
Applications:
These screening machines can be used universally for test screening or to produce between 2 and 4 screen fractions. A good screening effect is achieved by the circular vibration in the vertical plane.
Design:These dustproof machines are made of standard or stainless steel and activated by one or two maintenance-free vibrating motors with adjustable out-of-balance force.
Outstanding advantages:The special vibrator design permits different vibration characteristics, e.g. for gentle screening, long residence times, high throughputs or difficult-to-screen products.
Models and accessories: Cleaning of the screen cloth can be assisted by a ball rapper for small mesh sizes. Stands are available. |

Gravel, sand, coal and many basic materials must cover a long path before they are suitable for further processing. Vibration conveyors are an important part of this path. They drain the excavated sand, screen gravel according to grain sizes, take the load off breakers or mills of fine-grained material or assist in the cleaning of wash water. They are particularly for use in the basic materials industry, where vibration conveyors are characterized by their wear-poor, rugged construction and lifetime duration.
Precise screening to grain sizes in the range from 25 µm to 500 mm, high service and temperature resistance, for example in the case of supplying components to the melt furnace in glass production, are also advantages of vibration technology. |
