Application : Various nonmetal powder such as heavy calcium carbonate, light calcium carbonate, talcum powder,kaolin, graphite, BT-1500 Centrifugal Sedimentation Particle Size Analyzer

BT-1500 type has excellent performance and wide application, whichis all developed by us. It adopts gravity sedimentation, centrifugal sedimentation and the combination of them. The ingenious combination of centrifugal device and testing device leads to wide test range, easy operation, fast and precise test and real-time computer control. It is ideal for the particle test in production, scientific research and teaching.

Technical SpecificationSize Range: 0.1μm-150μmTest Mode: gravitational, centrifugal and combined modeRepeatability Error: <4%(D50 of standard sample)Operating system: Windows 2000, Windows XPInterface: RS232 or USBTest Time: Normally 3-15 minsCentrifuge Speed: 750 rpm , 1500 rpmApplicationVarious nonmetal powder such as heavy calcium carbonate, light calcium carbonate, talcum powder,kaolin, graphite, silica,bruite,barite, mica powder, communalizebentonite,diatonite, clay, etc..Various metal powder such as aluminum powder, zinc powder, molybdenum powder, tungsten powder, magnesium powder, copper powder, rare-earth metal powder, alloy powder, etc.Other powder such as catalyst, cement, abrasive, medicine,agriculture chemicals, food, paints/coatings, dyestuff, phosphor powder, river silt, ceramic material, etc.CharacteristicsThe combination of gravity sedimentation with centrifugal sedimentation leads to wide test range and easy operation perfect for the particle test of superfine kaolin and super fine heavy calcium superphosphate.With special synchronous technique, it can test particle size successively under high-speed centrifugal condition, which keeps the result repeatable and accurate.Standard USB connecting mode for data transfer and transmitting makes it easy to connect with various types of Laptops and PC by only one signal line, quite different from the conventional board and card mode.Standard Windows software with user-friendly interface offers easy operation. It has the functions of results saving, locating, comparison, merging, editing, delete, help and system failure self-diagnosing. The test result can be classified and converted to Excel file and figure.It has 3 different report forms both in Chinese and English including accumulative particle distribution data and graph, compartment particle distribution data, histogram and typical particle diameter range such as D3, D10, D25, D50, D75, D84, D90, D97, D98, etc. The user can edit the pattern, color, and typeface of the report form acc. to specific requirement.Accuracy and repeatability test results of BT-1500 (for standard sample)

Principle

Sedimentation method is applied according to different sedimentation speed generated by different particles in different diameter in some liquids.Put sample into some liquids to make suspension, the partilces in which will sedimentate by gravity or centrifugal force.Large particles will sedimentate faster and small will be slower.Stokes Law describe the relation between particle diameter and sedimentation .
