Introduction

Powder characterization includes flow measurements, morphology, particle size distribution, density, and chemical composition. Bettersize PowderPro Series instruments are mainly used for the analysis of the powder physical properties by testing items such as angle of repose and fall, angle of spatula (flat plate angle), bulk and tapped density, dispersibility, voidage and cohesion, angle of difference, compressibility, uniformity, flowability Index, floodability index, sieve size, angle of slide, etc.

What are bulk density, tapped density and compressibility, flowability index?

Bulk density: fill the powder sample into a measuring cup, and flatten the top, the ratio of the powder mass to the volume of the cup is defined as bulk density. It indicates the mass of the powder that can be added into the vessel per volume under normal conditions.

Tapped density: fill the powder sample into a measuring cup; vibrate the cup at a certain amplitude and frequency to remove air from the powders. After reaching the required vibration time, flatten the sample. The ratio of the powder mass to the volume of the cup is defined as tapped density. Tapped density indicates the mass of powders filled into the vessel per volume after excluding air from the powders. The data of bulk density and tapped density are often used for the design of vessels, bags, and tanks for powder storage.

Compressibility: it is the ratio of the difference between tapped density and bulk density to tap density. It shows the degree of volume reduction from bulk to tap state.

Flowability Index: is a set of numerical values obtained by the weighted summation of angle of repose, Compressibility, angle of spatula, uniformity, and cohesion. It is used to comprehensively evaluate the flowability of the powder. The Flowability Index is mainly used to describe powder flowability under gravity.

What are angle of repose, angle of fall, angle of difference, and flat plate angle (angle of spatula)?

Angle of repose: Under the static balance, the angle between the slope of a powder pile and the horizontal plane is angle of repose. It is measured when the powders fall to a surface via gravity and form a cone. It indicates the flowability of the powders. The smaller the angle of repose is, the better the flowability of the powders.

Angle of fall: After measuring the angle of repose, apply an external force to the powder pile to collapse it. The angle between the slope of the collapsed pile and the horizontal plane is defined as angle of fall.

Angle of difference: It means the difference between the angle of repose and the angle of collapse. The larger the angle of difference is, the better flowability of the powders.

Flat plate angle: immerse a plane in the powder pile; pull up the plane vertically, and one angle is formed between the slope of the powders on the plane and the plane. Apply an external force to obtain another angle. The average of these two angles is flat plate angle. The smaller the flat plate angle is, the better the flowability of the powders. The flat plate angle is usually larger than the angle of repose.

How to measure flowability of metal powders?

According to ISO4490, the flowability of metal powders is usually measured with a Hall flow meter.

The measurement process is:
- Weigh 50g + 0.1g sample;
- Plug the hole in the funnel with the finger;
- Pour the sample into the funnel;
- Quickly remove the finger from the small hole and start the stopwatch at the same time (precision 0.2S);
- Wait until the powder sample runs out, and stops the timing immediately;
- Evaluate the fluidity of the metal powder through the time of the 50g powder passing through the hole.
The standard funnel of the Hall flowmeter needs to be calibrated by a standard sample with a flow speed of 40 + 0.5s/50g.

Outstanding service

I have been using Meritics for a number of years and they always provide outstanding service and support.
They have a rapid response turnarounds and are very knowledgeable of the techniques and products they provide.

Good service, very helpful

We use Meritics for the PM service and installation of all our FlowCams . Megan has been coming to our site for a number of years. She is very efficient in her work, but most of all Megan is very helpful. We have had issues with one of instruments after the install and Megan did her utmost to try and solve it while on site, even though it wasn’t solved Megan has been in contact with the supplier of the instrument to try and solve this problem for us.

Good Service

David, our service engineer as usual was good at communicating and setting up the recent service appointment, he arrived on time, did the service promptly and informed me of any problems. Friendly and helpful

TomA-446
Superb and prompt service

I have used this company through the laboratory I work for frequently. We specialise in soil analysis, and Meritics were chosen as they have extensive knowledge of the instruments we use. We have several laser particle diffraction analysers with a service contract, and service is always very prompt and meticulous….

JamesG-2483
Good experience over two years

Meritics have covered the annual servicing of our Multisizer 4e instrument since we purchased it from them just over two years ago. The application scientist who performed the servicing was friendly, knowledgeable, and extremely helpful, happily answering a barrage of questions about how best to use and maintain the instrument. All my interactions with Meritics staff have been positive. I would happily recommend them.

RajG-62
Fully committed to customer service

Service second to none, both units serviced and all questions answers by engineer while on site.

Highly recommend Meritics for equipment purchases and aftercare services

After owning one of our instruments for over 8 Years which was purchased from Meritics, it suffered its first breakdown. Upon contacting Meritics, I was instantly put through to an engineer who was very helpful. Upon inspection of the manual, it was decided that it would be more cost effective to have a Meritics engineer visit. The Meritics staff were very communicative and kept me up to date.
Excellent Service

Lovely, friendly and extremely helpful. David and his team are always on call with advise and are very easy to work with and are always happy to help.

Professional, Customer-oriented, fast service

We had issues with one of the aperture tubes provided by Meritics on a Friday afternoon, while very pressed for a review deadline. Meritics handled our inquiries very fast and professionally and helped us out by shipping us their spare tube to use in the mean time free of charge, while we waited for our new tube to arrive. Communication was very pleasant.

VeerleB
Very helpful and prompt

I emailed for some technical help and also to get some spares and both the engineer (David) and purchasing (Sophie) were very prompt to respond and helpful. We do have a service contract but I appreciated being able to email the engineer directly.

Excellent Service

Used Meritics to conduct particle size distribution by laser diffraction. Service as last time, is very quick, well priced and professional.

I would highly recommend

GavinR-101
Excellent and Friendly Service

Always a pleasure to deal with the people at Meritics Ltd. They understand the importance of our work and the fact that our research projects have deadlines that need to be met. Consequently, problems are dealt with very quickly and professionally and they are willing to go that one step further to make sure their supply chain problems don’t become our problems. Thank you to the team for their support. It is greatly appreciated.
