HAVER test sieve shakers

Precision in a new dimension

In addition to high-quality test sieves, modern test sieve shakers are part of a high-performance overall concept. Haver & Boecker offers you a wide range of systems for the most diverse areas of application, which are state-of-the-art in terms of function and equipment.

Our laboratory screening machines are extremely flexible and can be precisely adapted to your specific requirements. This results in integrated solutions for the analysis of sieveings of almost any shape, size and composition.

Three-dimensional sieve movement

Haver & Boecker test sieve shakers produce a three-dimensional sieving motion. The screenings are accelerated vertically out of the meshes and simultaneously distributed over the screen surface in a circular motion. In this way, your sieving results are not only available to you incredibly quickly; they are also optimally reproducible at the same time.

 

Automatic amplitude control

For all electromagnetically operated test sieve shakers, we also use G-Control – an automatic amplitude control with permanent acceleration measurement of the entire sieve tower. This technology reliably compensates for all natural vibrations of the screening machine and the substrate. In this way, it ensures a constant amplitude value – regardless of the sieve load and the ambient conditions.

general points

The HAVER UWL 400 for test sieves with sieve frames made out of stainless steel or wood is specially designed for dry or wet sieving of coarse-grained sample material. Two three-phase unbalance motors drive this most powerful test sieve shaker from Haver & Boecker and generate a three-dimensional sieving motion.

  • The 3D sieve movement saves time and manual re-sieving
  • Optimum sieving results with large sample quantities due to a robust unbalance drive

Accessories for test screening machines

For all test sieve shakers, Haver & Boecker offers a comprehensive range of accessories and spare parts for dry and wet sieving.

Sieve pan with spout

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.

Retrofit kit for dry and wet sieving

All HAVER test sieve shakers with external control can be used for dry and wet sieving. For dry sieving you need a machine lid with a sight glass and a closed sieve pan; for wet sieving a machine lid with wide spreading spray diffuser and a sieve pan with outlet.

HAVER TwinNut quick-release clamping system

The ideal solutions for fixing the sieve tower on HAVER test sieve shakers are the Classic clamping system and the TwinNut quick clamping system. The difference lies in the TwinNut clamping system that can be opened, which allow a height adjustment without time-consuming turning. They are particularly suitable for sieving with frequently varying sieve towers.

HAVER sound absorbing cabinet

To reduce the noise level in the laboratory environment, you can also operate your test sieve shakers in a soundproof cabinet. Depending on the machine type, the sound level can be reduced by up to 28 dB (A). Double viewing doors in the sound insulation cabinets for the HAVER EML 450 digital plus and the HAVER UWL 400 make it easier for you to access the machine.

Reducers

With appropriate reducers, you can also use all test sieves with stainless steel frames in mechanical sieving. Test sieves with a 76.2 mm diameter fit the HAVER EML 200 digital plus, 200 test sieves fit all HAVER test sieve shakers.
