HAVER & BOECKER is one of the world's leading wire weaving companies. We also produce woven wire cloth for sieve analysis machines for HAVER Particle Analysis, especially for test sieves. Test sieves and sieve analysis machines are prescribed for conventional sieve analysis of bulk material, whereby HAVER Particle Analysis sets benchmarks in quality and diversity. We offer the greatest variety of sieve analysis machines concerning all relevant standards and designs and also laboratory test sieve shakers and virtually indispensable accessories for a complete sieve analysis.

HAVER / W.S. TYLER® Test Sieve Shakers

With our variety of sieve analysis machines for dry and wet sieving all materials can be classified, also agglomerating grinding material and coarse-grained products. The self-readjusting amplitude is the main feature of HAVER 3D laboratory sieve shakers with electromagnetic drive. Main feature of almost all W.S. TYLER® Ro-Tap® sieve analysis machines is the mechanical circular and tapping motion.

Product Services

Test sieves, sieve analysis machines and the HAVER CPA systems are test and measuring devices which, according to DIN EN ISO 9000 ff, must be certified, and regularly monitored and checked in operation. For this reason, we provide comprehensive test certificates and service for ongoing regulation-compliant quality assurance.

Control of Test Sieve Shakers

We test the operation, safety and condition of your sieve analysis machines, either in our laboratory or directly on-site. The units are subjected to comprehensive system diagnostics and functional tests. These are used to determine and, if necessary, readjust the amplitude characteristics. Following successful testing, we issue an Inspection Certificate 3.1 in accordance with DIN EN 10204. If we find unacceptable deviations and faults, we will provide you with a cost estimate for repairs and restoration. We recommend the control of a frequently used sieve analysis machines every two or three years.
