Mixing systems that include a mixer housing and one or more disk assemblies for mixing and processing materials is disclosed. The disks rotate to mix an additive into the material and to carry agglomerated solids toward a discharge of the mixing system. The disks may have a plurality of fingers or lobes which extend from a central portion of the disks.

The invention relates to a device for generating gas bubbles in a liquid in a container, including at least one rotatable hollow shaft arranged horizontally in at least one container; at least one gassing disc arranged vertically on the at least one hollow shaft; and at least one feed line for supplying at least one compressed gas to the interior of the at least one hollow shaft, said compressed gas being brought into the feed line and hollow shaft directly, without a liquid carrier.

An apparatus is equipped with first and second rotary shaft 3, 4 and a plurality of disks 40, 50 provided upright at equal intervals on the respective rotary shaft. The disks are heated or cooled from the inside, and a raw material is heated or cooled by bringing it into contact with the disk surfaces. Scraper members 45, 45 and 55, 55 that enter between the surfaces of the facing adjacent disks to scrape the raw material are fixed to each of the disks 40, 50. The first and second rotary shafts 3, 4 are rotated at unequal speeds such that the scraper members approach the facing disk surfaces with trajectories drawn thereon varying, so that the raw material that has adhered to the disk surfaces can be effectively scraped off.

A dry powder kneading apparatus includes a main body including an inner space into which a mixture containing an active material, a conductive material, and a binder is supplied, and a screw inside the inner space of the main body, the screw being configured to move the mixture in one direction and to knead the mixture into fiberized dry powder, and a rotation torque of the screw being 1.4 kgf.Math.m to 42 kgf.Math.m.

A method for preparing direct melt-spun high-viscosity PBAT/low-viscosity PET two-component elastic fiber and a high-viscosity PBAT polymerization reactor. This method uses two production lines respectively used to produce a high-viscosity PBT melt and a low-viscosity PET melt, which are then spun. The high-viscosity PBAT production line comprises a first esterification reactor, a second esterification reactor, a first prepolymerization reactor, a second prepolymerization reactor, and a high-viscosity PBAT polymerization reactor. The polymerization reactor is designed with a special disc structure in a parallel two-shaft disc reactor, and the two shafts are rotated in opposite directions, improving the devolatilization effect and self-cleaning, significantly increasing the viscosity. By using this method, the cost is low and the production capacity is high, the process flow is shortened, the fiber strength can reach 2.552.85 cN/dtex, the crimp shrinkage rate can reach 25%60%, and the crimp stability can reach 58%70%.

Mixing systems that include a mixer housing and a plurality of roller assemblies for mixing and processing materials is disclosed. Each roller assembly includes a roller that extends between sidewalls in the mixer housing and rotates to mix an additive into the material and to carry agglomerated solids toward a discharge of the mixing system. Each of the rollers may have a protrusion geometry formed in the outer contact surface, where each protrusion geometry is complementary to an adjacent roller.
