The SPECTester - Questions and Answers
A list of Frequently Asked Questions for the SPECTester.
Mini Case Studies with the SPECTester
The SPECTester unit should be found in any industry with R&D and/or production facilities where the particles and granulates handled are smaller than 9.4 mm. The Target Markets are Foods, Chemicals, Pharmaceutical, Cosmetics, and Mining.
Comparison of New Bulk Strength Measurement Technique with Traditional Schulze Method
Bulk solids behave differently from typical fluids. When a fluid is placed in a container with an opening, it flows through that opening. The question to be answered is: how fast does it pass through that particular opening?
Taste the Difference – A New Method of Measuring Segregation: Steak Seasoning, a Case Study
Bulk solid processing generally fails due to one of three problems. The material may hang-up in the system, the material flow rate cannot be controlled by volumetric feeders, or the material segregates during handling and processing creating quality problems. The focus of this paper will be diagnosing and solving segregation problems.
Bulk Properties of ARGO Cornstarch as Measured with the SSSpinTester®
For the process engineer, strength is the key property that determines if a bulk material will arch or form stable ratholes in process equipment. Since the goal of powder processing is to maintain reliable flow, arching and rathole tendencies are considerable problems. Strength is a far reaching flow property that controls the behavior of the bulk material in many processes.
The Product Fits the Bill – Successful Product Design
Two Primary Product Design Rules: • Understand the role of particle scale properties on bulk unconfined yield strength • Calculate strength directly from models involving particle scale properties and by some direct measurements of bulk properties
