    Post Selective Breaker for Coal & Stone

    Hello everyones !

    I would like to know about the requirement of using a selective breaker for separating packstone from coal production.

    We have experience using this kind of of equipment, but not successful. The result was that the stone couldn't be separated from the coal or in other words that the waste and the result stiil consisted of stone and coal. I wonder that there might be requirement of the characteristic of coal proccessed.

    If you know a details about this I would like get the information from you.

    Thanks

    selective breaker for separating packstone from coal production.

    Rotary Breaker which can separate stones from ROM coal can be effectively used. It uses difference in crushing strength due to gravity impact, between coal and stone.

    Lightbulb Fly Ash classification

    Cemex operating their first TriboClassifier
    Adi Mogilevsky, Marketing Director
    Jerusalem, Israel, April 8 2003. Mexico-based multinational giant CEMEX S.A. de C.V., (NYSE: CX) (www.cemex.com ) and Israeli Jerusalem based company Sortech Separation Technologies Ltd. are working together to develop a fly ash beneficiation plant based on Sortech's unique dry powder separation technology - the TriboClassifier. A laboratory scale machine is currently operational at Cemex headquarters in Monterrey, Mexico.
    "This is a joint development to ramp up to a pilot plant construction," said Sortech CEO, Oren Elkayam, "and then we will move into a future discussion regarding the technology based industrial plant at Cemex's Bogot site."
    Sortech representative Dr. Robert Asimow visited Cemex headquarters in Monterrey, Mexico on March 26 (see photos) to evaluate fly ash separation results achieved on Sortech's laboratory fly ash separator with 50kg/hour capacity.
    There are two primary beneficiation criteria for fly ash: low unburned carbon content (Loss on Ignition, LOI) as well as high "fineness". According to the US and European standards for fly ash used in cement, LOI content should be less than 6% and no more than 34% of the particles should be larger than 45 microns. In practice, some concrete manufacturers and state regulations require a maximum of 3% LOI and maximum 8-12% coarse particles.

    The Triboclassifier process separates the fine particles from the initial fly ash. These fine particles are of high value to the concrete industry as they are both highly reactive and low in LOI.
    According to Dr. Asimow, Cemex production experts in Mexico and managers in Switzerland have recently conducted a videoconference during the visit and confirmed TriboClassifier's technology is a potential good match to the Cemex plant's processes, which are predominantly aimed at making raw materials for sale to a cement market. The high-volume fly ash concrete system provides a model for the future for making concrete mixtures that shrink less, crack less, and would be far more durable and resource-efficient than conventional Portland cement concrete. [1]
    The fly ash separation is not the only application of Sortech. Markets including metal powders, pharmaceuticals and other dry powders separation applications are being investigated, said Elkayam.

    About Sortech
    Sortech Separation Technologies Ltd. is a Jerusalem based start up company founded in 1997.
    The TriboClassifier developed and patented (USA # 6,439,394 B1 and # 6,095,965) by Sortech uses a new technology for dry bulk powder classification.
    SorTech has developed a novel classification process based on triboclassification. The Triboclassifier utilized the principal that, if a particle is moving over a surface whose roughness is comparable to the particle size, the apparent coefficient of friction depends on particle size.
    The TriboClassifier is suitable for bulk powder with mean particle sizes in the range of 10m to 300m.
    The TriboClassifier process uses a rotating conical bowl. The surface roughness and rotational speed are adjusted to best suit the particular classification requirement.
    The TriboClassifierTM is fully enclosed with a small footprint, has a very modest power requirement and can process powder at the rate of several kilograms to tons per hour.
    The companys experience, extensive research and development on a variety of materials having different separation objectives, shows that the Triboclassifer can provide the most efficient solution to many existing requirements. For more information, visit www.sor-tech.com

  6. Hello Suratman,

    Please refer the thread Separation Coal and Pack stone in the forum Mechanical Conveying. In this thread I have given two messages which describe one method in reasonably good detail to separate out stone from the coal. This information may be of interest to you.
