Haver & Boecker is your contact for all cases: simply because we offer you the right test sieve that complies with the standards for every screening task. Standard test sieves made out of stainless steel are just as much a part of our range as test sieves for grain analysis or test sieves with beechwood frames. Hand screening, conventional screening, dry or wet screening: Analyse bulk solids from 5 µm to 125 mm.
Very accurate and extremely stable
All HAVER test sieves are manufactured in compliance with the current test sieve standards. They are all characterised by particular accuracy and stability
That is: You can always rely on our test sieves. High-quality frame materials, the extremely stable screen construction developed by us and careful workmanship guarantee a long service life and the perfect functioning of our test sieves.
For sustainable and compliant quality assurance, we provide you with comprehensive test certificates and services. Whether it is recertification of the measuring equipment in our works laboratory – tested according to DIN EN 10204 with acceptance test certificate 3.1 or by our accredited calibration laboratory for test sieves with metal mesh according to DIN EN ISO/IEC 17025. The recertification and the calibration procedure carried out ensure traceability to the national measurement standard.
Test sieves with a stainless steel frame and nominal sizes from 5 µm
We equip our standard test sieves with a stainless steel sieve frame with a wire mesh sieve tray or robust perforated plates in accordance with DIN ISO 3310.
If your focus is on tighter tolerances, our "Gold" grade sieves are the right choice. The test sieves with elcectroformed sheets are suitable for the finest materials from 5 µm.
Our special test sieves for grain, tobacco and rock
We also offer you the right test sieves for the analysis of grain and tobacco. In addition to our standard sieves, we mainly use sieves with long perforations that are manufactured according to a special grain standard. We manufacture special grid sieves to determine the flatness index for aggregates.
ALPINE test sieves with mesh sizes from 20 µm
If you are familiar with the ALPINE air jet test sieve machine, then you are certainly also familiar with the Haver & Boecker test sieves specially made for it. With the help of these test sieves you can analyse the finest dry bulk materials.
In addition to the sieves for the 200 LS and 200 LS-N, we also manufacture the version for the e 200 LS with fully automatic sieve detection.
Sieve covers serve to protect the stored test sieve from dirt and dust. They are also used to store classified material in the individual test sieve or in the entire sieve tower. We offer sieve covers for all test sieves with stainless steel and wooden frames.
Sieve pans catch the underflow of the bulk material and thus the finest particles. For wet sieving, you need a sieve pan with a full useful height and an outlet with a drain hose. These are equipped with an inclined bottom up to a diameter of 203 mm; the larger sieve pans for wet sieving have a straight bottom.
We offer intermediate rings and intermediate pans for all stainless steel test sieves. Intermediate rings are used to raise a sieve tower of less than three test sieves. In this way, it achieves the minimum height required for HAVER test sieve shaker. Intermediate pans allow you to have several sieves at the same time on one laboratory sieve shaker.
You can easily mount the sieve holder in the space-saving design in many variants. It allows gentle and well-arranged storage of up to five test sieves with 200 mm or 203 mm diameter. Thanks to individual labelling fields, you know at a glance which test sieve it is
HAVER Drip-off Weight Test Set
The HAVER Drip-off Weight Test Set is used for testing products from the fish and meat industry as well as for canned fruit and vegetables. The tilting device can be fixed to a maximum tilt angle of 20° after input of the draining material. In addition, the Drip-off Weight Test Set includes a test sieve with a mesh size of 2.80 mm, an intermediate pan and a sieve pan with outlet.
You avoid particles getting stuck between the sieve cloth and the clamping ring of the test sieve by additionally opting for additional pasted seam above and below the sieve cloth.
Normally, all HAVER test sieves with stainless steel frames are equipped with a sealing ring made of PVC, which is temperature resistant up to approx. 130°C. On request, we can also equip your test sieve with a VITON sealing ring. We recommend this for an ambient temperature of -15°C to +200°C.
Rubber balls and rubber cubes belong to the screening aids. They are placed on the test sieve, clean the meshes during sieving, destroy agglomerates and lead to an acceleration of the sieving process.
The deaeration ring prevent the formation of air pockets underneath the sieves during wet sieving, which prevent the liquid from draining off. The venting rings are available for the common sieve diameters.
