Sieve Pans for Dry and Wet Sieving
Sieve pans collect the sieve underflow of bulk material. These are the fine particles. Please note that you need test sieves with discharge nozzle for wet sieving. Sieve pans with diameters up to 203 mm are equipped with bevel bottoms, larger sieve pans made from stainless steel with plane bottoms.
Retrofit Kit for Dry and Wet Sieving
Our HAVER Test Sieve Shakers with external control gear can be used for dry and wet sieving. For dry sieving you need a cover with inspection glass and a closed sieve pan, for wet sieving a cover with wide spreading spray diffuser and a sieve pan with discharge nozzle.
TwinNut Rapid Clamping System
For fixing the sieve tower on HAVER Test Sieve Shakers we quote the clamping system Classic and the quick-release clamping system TwinNut. They differ in parting TwinNut knurled nuts, which enable height adjustment without time-consuming screwing, and especially suit sieving with frequently-diversified sieve towers.
