Forty litre bulk sample Spinning Riffler (SR40B)
Microscal's Spinning Rifflers (SRs) are manufactured with hopper capacities from 25ml to 40 litres.
The Forty Litre Spinning Riffler has two versions. The 'B' version (SR40B) extracts eight representative samples in one pass, nominally five litres each. All eight samples must be collected as there is no provision otherwise to collect the over–spill. The sample collectors are stainless steel.
Microscal's laboratory spin riffling instruments are designed to handle materials with a wide range of particle size, cohesion, and density. Powders and granules from sub–micron to 4·75mm (#4) top size can be riffled.
Large bulks may be sampled using an SR40 riffler before feeding the resulting portions through a smaller instrument. The representativeness of the final sample is assured even when the ratio of initial bulk to final sample size is 100,000 to 1, particulate properties permitting.
Recombining samples after riffling to generate desired quantities for round–robins, standard samples of materials, or particular tests are distinct advantages of the riffling technique.
All forty litre Spinning Rifflers are equipped with an enamelled steel gap–adjustable hopper, an adjustable–rate vibratory feeder with an enamelled feeder chute, synchronous motor turntable drive, stainless steel collection vessels, and an optional hopper filling aid.
Parts for the SR40 instruments are NOT interchangeable with other models.
Spinning Rifflers fit appropriately into your analytical procedures at the sample preparation stage. Customer's special requirements will be carefully considered. |
