As you have probably found, hard ceramic spheres have a great ability to peg a conventional screen surface. We found this out while making proppants many years ago.

We used a probability type screen with some sucess to overcome pegging problems for a primary split within the process, but the cut may not be sharp enough for your purposes. Mogensen Sizers have a test facility in Hamburg which we found useful.

Following the Mogensen, we used two Sweco style screens with 6 ft diameter, feeding a couple of air tables that ran at around one tonne an hour each, as I recall.

These screens were fitted with ball decks, but it was still necessary to remove the screens and de-peg them on a regular basis. Since those little spheres make for very dangerous walking surfaces and will get into any available gaps, a dedicated cleaning area might be a good thing to plan for, as would rotable spare decks. ■

Our company is producing tailor-made Cenospheres and Ceramic Microspheres want to buy Sieving machine to separate fines of 150 to 50 micron from a feed product range of 10-300 micron with a accuracy of 95%. The desired capacity should be 1 ton per hour. The product is low specific gravity product and spherical in shape.

Hello sir,

Thank you for your inquriy.

After your letter, we have know about your sieving requriment preliminarily.In order to recommend a set of best suitable sieving machine for your product and come your sieving aim. we hope to get your support to fill in our information collection table.

After know about your requriment completely ,we will offer the drawing and price to you.Thank you for your kind supportment.

IF You do not mind ,we hope you can post 50kg material to us ,we will test them and then give you the result.

Dear geospheres,

we supply screen-feeders with ultrasonic-screendecks for fine bulks. Last device sold, had a screen with 200 micron (e.g.).

If you are interested please send me an e-mail or PM. We will need some more details of the bulk/product.

Many thanks and best regards!

As you probably know, using screens to make separations as fine as 50 micron can be very problematic and inefficient. You may want to consider using an air classifier to dedust at 50 microns and a screen to scalp the top at 150 micron. The MicroSizer air classifying system does an excellent job with applications such as yours. We would appreciate the opportunity of demonstrating the effectiveness of our equipment. If interested, I may be reached at the following number:

dear sirs,

we are producers of air classifiers. these are used when sieving operations fail. especially when considering the micron sizes that are required by you. depending on the execution of the classifier, we are able to generate extremely precise cut-points with these units.

looking forward to your contact, we remain

with best regards

You have only written that material has low bulk density.

The microspheres, I had used had a bulk density in the range of of 0.15 to 0.20 g/cc.

I am not sure dry screening on conventional screens is possible.

Wet circuit separation is possible if you have possibility of drying the products after separation. ■

We have supplied many machines for this application. It is not an easy job but can be done successfully with vibrating sieves if the correct techniques are used.

If you want to know more then contact me on
