In order to attain the object, a method for producing rice flour includes: providing primary crushing material rice subjected to soaking and adjustment of moisture content with a disintegrating and sizing device, fine grinding the primary crushed rice with an air mill, and then drying the fine ground rice with an air flow dryer. | 10-16-2014 |
20140346261 | EGGSHELL MEMBRANE SEPARATION PROCESS - A method is provided to separate an eggshell membrane from the outer shell of an egg. The method includes first adjusting the moisture content of an eggshell which includes a shell and a membrane. The eggshell is then subjected to airflow, such that the shell is broken and detaches from the membrane resulting in shell particles and membrane fragments. The shell particles and membrane fragments may be further dried and separated. The membrane fragments may then be processed. In some embodiments, the moisture content is adjusted to less than 24% such as by drying the eggshell. The eggshell may be pulverized resulting in shell powder or dust. The membrane fragments may be further processed for storage, transport, or the final application of same, such as by drying, grinding, and/or freezing. | 11-27-2014 |
20140374516 | DRUG/CARRIER INCLUSION COMPOSITES PREPARED BY A MECHANOCHEMICAL ACTIVATION PROCESS USING HIGH-ENERGY FLUID-JET MILLS - Disclosed is a process for the preparation of drug/carrier inclusion composites which involves co-grinding the mixture of drug and carrier powders in a fluid-jet mill, in particular one using air or nitrogen as the fluid, which is suitably modified to allow mechanical fusion of the powders. | 12-25-2014 |

20150144718 | IMPACT GRINDING PLANT FOR THE COMMUNITION OF ORE - There is provided an impact grinding assembly. The assembly, according to one aspect, includes a pair of conveyors for conveying at least partially unground material. Each conveyor has a lower portion and an upper portion which is spaced-apart above its lower portion. The assembly includes a pair of vibrating impact plates aligning below the upper portions of respective ones of the conveyors to receive the at least partially unground material. A first one of the impact plates operatively directs material thereon to the lower portion of a second one of the conveyors. A second one of the impact plates operatively directs material thereon to the lower portion of a first one of the conveyors. The impact grinding assembly may further include a material-separation assembly for removing material from the conveyors which has a particle size no greater than a desired particle size. | 05-28-2015 |
20150343453 | FLUID ENERGY MEDIA MILL SYSTEM AND METHOD - A system for wet milling or dry milling at least one material. The system includes a milling apparatus and at least one milling medium. The milling apparatus includes a chamber, at least one inlet, at least one outlet and a fluid pump. The fluid pump facilitates concomitant flow of the milling medium and material to be milled within the milling chamber to effect milling of the material. | 12-03-2015 |
20160144375 | VSI-CRUSHER FEED HOPPER DISTRIBUTION DEVICE - A vertical shaft impact crusher feed hopper distribution device arranged for feeding material to be crushed to a rotor of a vertical shaft impact crusher. The feed hopper distribution device is arranged to be mounted in a feed hopper that feeds material to the rotor and includes a supply channel that forwards material from an inlet opening arranged adjacent to an upper end of the supply channel to a hopper bottom opening arranged in a bottom of the feed hopper and communicating with the rotor. The supply channel has a cross-section that widens along at least a portion of the distance from the upper end to a lower end of the supply channel. | 05-26-2016 |
