Laboratory sorting machines

LABORATORY SCREENS

Circular screens

With diameters of 100, 200, 300, 400 mm; we can also supply screens whose diameter is given in English inches, but we do not recommend combining them with screens manufactured in millimeter diameters (deviations).

Square screens

In a beech frame with dimensions of 500 × 500 mm or 300 × 300 mm.

Screens for alpine sorting machines

Old and new generation (diameter 200 or 203 mm).

Certification

Screens are normally supplied with a sales protocol, in which the manufacturer confirms that the technical fabric inserted into the frame has been measured and approved; upon request, we can provide verification or calibration (not included in the basic price of the screen).

The sieves are manufactured according to DIN ISO 3310.

LABORATORY SORTING MACHINES

Laboratory analytical sorting machines (sieving machines) are used for the automatic sorting of bulk materials into individual fractions. They enable regular analysis results to be obtained in a very short time. The sorting process simulates manual sieving as the basis of the entire separation technique.

NEXOPART laboratory machines create a three-dimensional sieving movement, stratifying the sorted material over the entire surface of the sieve. For materials that are difficult to sift, the process can be programmed to be interrupted, which intensifies the sieving. This speeds up the entire process.

NEXOPART analytical sieve shakers with electromagnetic drive have no rotating parts, are very robust, do not require regular maintenance, and are minimally noisy. They have a double spring system, and the use of cast iron parts makes their construction solid. No unwanted vibrations are transmitted to the fixed parts of the analytical sieve shaker and its base. They have versatile uses.

CPA SOFTWARE

Computer program for evaluating sieve analyses

This software was developed for computer evaluation of sieve analyses according to valid standards. For entering basic data into the PC and after the sieving process, the individual analytical sieves with excess material are completely weighed. (The determined weights can be entered manually or are automatically transferred from the balance to the PC.) CpaServ SOFTWARE  evaluates sieve analyses. WE SUPPLY IN ENGLISH OR GERMAN VERSION.

Photo-optical analysis

NEXOPART- CPA

The NEXOPART - CPA device can be used to perform grain size and shape analyses. The device, built on glass fiber technology, measures dry and non-agglomerated bulk materials in the measurement range from 40 µm to 400 mm. The principle is similar to that of a fax machine, where a stream of particles is continuously scanned.

Compared to other optical measurement methods, it achieves a significantly larger measurement range and faster passage of the measured material. The digital CCD line camera processes over 20 million pixels and up to 4,000 particles per second at a resolution of up to 12 µm /pixel/. System performs more than 33,000 scans per second.

NEXOPART -CPA analysis provides grain shape values, particle count, information on particle circumference and surface area, grain distribution in arbitrary size classes and other parameters. Grain size analysis shows the grain size distribution as an undersized, oversized or density curve.

The results are displayed in a table or graphically. These devices can be operated down to -40°C, e.g. in the food industry. Online devices are used in a wide variety of industries. They are used for continuous optimization of production. All common interfaces are set.
