This enabled operators to change the setup of the sieves
rapidly to screen different products without needing to detach the mesh screen and deck individually.
There's scope for clever public procurers to adjust the sieves
so allowing a variation of 'peas' to get through.
Sand A is a 5-sieve
sand because 10% or more of the sample was retained on each of five adjacent sieves
(40, 50, 70, 100 and 140).
During the 1950s and '60s, the gospel of molecular sieves
spread and the business prospered.
As mentioned earlier, the success of the silylation was measured by looking for the presence of nitrogen using XPS analysis of the treated sieves
, Table 2 summarizes the amount of nitrogen detected for the various silylating conditions.
Depending on the size of the openings, they can adsorb molecules readily, slowly, or not at all, thus functioning as molecular sieves
-- adsorbing molecules of certain sizes while rejecting larger ones.
Unlike conventional vibrating screeners, the high performance Russell Compact Sieve
[R] is able to screen the milk powder at this finer mesh size without compromising flow rates, preventing the sieve
from becoming a bottleneck in the process.
It also features direct transfer of weighing data, a tabular or graphical format for representation of resultant data, and a user-friendly interface for control of the sieve
shaker AS 200 control, Retsch says.
Standard 8-in, round test sieves
analyze individually loaded samples, multiple samples staged for continuous testing or online testing in conjunction with automatic sampling devices.
Compatiblization between sieves
and polymers was achieved both by the use of flexibility during membrane formation and chemical coupling.
Loic Vanel of the University of Pierre and Marie Curie in Paris and his colleagues measured pressures beneath piles made either by pouring sand through funnels or letting it rain through sieves
Pavilion enables us to control the distillation columns and molecular sieves
processes, which are challenging to manage optimally and yet critical to achieve our operating objectives -- more, high quality ethanol for less.
