20090321980 | Method and Apparatus for Producing a Coal Cake for Coking - The invention rates to a method and apparatus for producing a coal cake for coking, in which a bed ( | 12-31-2009 |
20110031642 | PRESSED POWDER ELEMENTS - Method for producing a pressed powder element, wherein the method comprises pre-pressing of loose powder to a first powder blank ( | 02-10-2011 |
20120043685 | POWDER PARTICLE SHAPING DEVICE AND METHOD - A powder particle shaping device is provided, which includes a closed cavity capable of changing between multiple shapes as an external pressure changes, and the closed cavity compresses and moves powder particles with which the closed cavity is filled full while the shape changes. A powder particle shaping method is further provided, which includes a. filling a closed cavity full with powder particles to be shaped; and b. applying a varying external pressure to the closed cavity, such that the closed cavity changes repeatedly between multiple shapes, thereby making the powder particles under compression move and be subject to friction. The shaping device and method according to present invention have highly controllable shaping processing intensity of powder particles and stable processing strength, and thus are applicable to shaping and pulverization of various powder particles, and also applicable to pulverization and further shaping processing of dispersed agglomerates. | 02-23-2012 |
20120161354 | METHOD AND APPARATUS FOR COMPRESSING PARTICULATE MATTER - A compression molding apparatus for particulate matter comprising a magnetostrictive actuator functioning as an impact force applying means arranged at least between an upper ram or a lower ram and an upper punch or a lower punch. Particulate matter is compressed by a static pressure, and then an impact force is applied to the particulate matter to reduce internal stress. After compressing the particulate matter by the static pressure, the upper ram is allowed to fall gravitationally to shorten a molding time. | 06-28-2012 |
20120326351 | Method of reconstructing rubber from crumb rubber and making composite materials therefrom - A method for reconstructing rubber from crumb rubber includes mixing the crumb rubber with a binder of either urethane or sodium silicate, applying pressure to the mixture until the crumb rubber is flowable and molding the flowable rubber. | 12-27-2012 |
20150076729 | HIGH-DENSITY MOLDING DEVICE AND HIGH-DENSITY MOLDING METHOD FOR MIXED POWDER - A first die is filled with a mixed powder prepared by mixing a low-melting-point lubricant powder into a basic metal powder in a weight ratio of 0.1 to 0.2%. A first pressure is applied to the mixed powder in the first die to form a mixed powder intermediate compressed body having a true density ratio of 80 to 90%. The mixed powder intermediate compressed body is heated to the melting point of the lubricant powder. The heated mixed powder intermediate compressed body is placed in a second die that is pre-heated to the melting point of the lubricant powder. A second pressure is applied to the mixed powder intermediate compressed body in the second die to form a high-density mixed powder final compressed body. | 03-19-2015 |
20150328805 | PUNCH FOR POWDER PRESS - A punch for simultaneously pressing two or more different powder formulas has a punch body with a first region and second region. The first region is comprised of a first material and configured to apply a first predetermined pressure to a first powder formula when a ram force is placed on the punch body. The second region is at least partially comprised of a second material and is configured to apply a second predetermined pressure to a second powder formula when the ram force is placed on the punch body. The second material is less hard than the first material such that the second predetermined pressure is less than the first predetermined pressure. | 11-19-2015 |
