Abstract:
A method of preparing an aluminum metaphosphate (ALMP) particulate product includes charging a milling chamber of a ball mill with grinding media and loading an ALMP feedstock into the milling chamber. The ALMP feedstock is milled with the grinding media into ALMP particles at a particle reduction index in a range from 0.25 to 0.5. At a plurality of time steps during a period in which the milling is carried out, a fine fraction of the ALMP particles is removed from the milling chamber while a coarse fraction of the ALMP particles remains in the milling chamber for additional milling. An ALMP particulate product with a particle size distribution having a median particle size in a range from 100 μm to 700 μm is prepared from the ALMP particles removed from the milling chamber.

Abstract:
A grinding circuit includes ore and fluid feed lines, a grinding mill connected to the feed lines, a grinding chamber to produce a crushed resultant fluid having ground fines and large particulate therein, a cyclone for receiving crushed resultant fluid having ground fines and large particulate and for expelling at least part of the fluid and the ground fines and dispelling a remainder of the fluid, large particulate and another part of fine grounds gravity flow, a pump to cause the first crushed resultant to flow into the cyclone, a second fluid feed line. A density separator receives the remainder and additional fluid to cause upflow current therethrough such that a part of mixed fluids and the large particulate gravity flow to the grinding mill and at least part of the mixed fluids and another part of the ground fines are circulated back to the cyclone.
Abstract:
There is described an equipment as well as a process for the production of soybeans in a hammer mill comprised by rigid bars (21) hingedly coupled to one or more disks, the peripheral velocity of said bars being above 60 meters per second. The equipment comprises a perforated screen (25) with openings of a size equal to or smaller than 15 µm, placed inside the housing of the mill between the part (20) containing the hammers and the outlet opening (26), the latter being connected to a centrifugal fan (14) which aspirates said soybean flour which is pneumatically conveyed to a cyclone (17) wherein occurs the separation of the solid (powder) from the air stream, allowing the product to be packaged by means of known devices.
