HAVER EML 450 digital plus is the first test
sieve shaker in the world with a three dimensional sieving action
and self-adjusting amplitude to be fitted with test sieve diameters
up to 450 mm. Only three years after the introduction of the HAVER
EML 300 to the market this new development completes the Haver
& Boecker premium product range "digital plus".
The EML 450 digital plus can be used with all current sieve
diameters of 200 to 450 mm. This offers the opportunity to use
one machine for varying product quantities and different sieve
diameters.
As with all test sieve shakers from the Haver & Boecker
series "digital plus", the EML 450 is controlled by
micro processor. The self-adjusting amplitude compensates via
permanent acceleration control of the total sieve column the
vibrations of the sieve shaker and its stand. This guarantees
equal amplitudes even if different material quantities are analysed
at different stands - a guarantee for analyses complying with
ISO 9000 standard.
The EML 450 digital plus with electromagnetic drive has no
rotating parts, is extremely durable, maintenance free, very
adaptable and has a low noise level. Due to the use of a special
spring system and cast iron parts, the construction is heavy
and sturdy.
This new development enables those users, who often have to
analyse materials with apparent weights of more than 10 kg,
to noticeably reduce the external influence factors during the
sieve analysis and thus to obtain reproducible sieving results.
