A pin mill includes a rotor plate mounted on a shaft and having concentrically spaced-apart circular arrays of pins arise from an end face. The rotor pins interdigitate with complementary concentric arrays of pins arising from a face of a stator mounted on a door. The door swings open on a hinge mounted on two translator pins so that the door can translate the interdigitated pins before swinging open so that the pins arrays do not collide with each other while the door is opening. The rotor operates within a rotatable cylindrical screen which retains particles being broken up until they are small enough to exit. The rotor includes a circular array of vane knives which sweep closely within the screen and also entrain cooling air into the macerating volume of the mill. Oversized particles trapped in the screen also get cleared and split apart by the passing vane knives.

Methods and systems for isolating a high purity starch stream are provided. The methods provide an initial treatment step in advance of traditional grinding or fractionation operations (such as dry milling or wet milling operations) that facilitate separation of starch from other components of starch-based grains, for example facilitate separation of soft endosperm from other components of corn kernels including hard endosperm. The systems include a first treatment system for separating a high purity starch stream from other components of the grain stream, wherein the system can be configured as a bolt on for traditional milling operations such as wet milling and dry milling operations.

Method for converting brown coals, including leonardite, into humic fertilizers and fuel briquettes, comprising first grinding the raw material to less than 3 mm and subsequently treating it with water or water solutions, using liquid-phase mechanoactivation and/or mechanochemical activation, with a duty of water curve ranging from 0.9 to 2.5 and with reaction composition dispersion by chafing and dynamic shift by exposing the medium to a hydraulic impulse of sonic and infrasonic frequencies, by metered introduction of 10 to 40 MJ per cubic meter of mechanical energy, with automatic limitation of the energy in the sub-cavitation area for preventing the mechanochemical reactors from falling into cavitation modes; the method further comprises separation of converted suspension compositions into solid and liquid phases in the centrifugal force field, optionally acidizing the liquid phase with the withdrawal of humic acids from the liquid phase to the heavy phase and recycling of residual water.

A method for producing a homogenized mixture of carbon, sulfur, and PTFE, wherein the sulfur is liquefied, and the liquid sulfur is then ground for the first time together with the carbon, so that the liquid sulfur is absorbed by the pores of the carbon particles and forms a preferably powdery composite with the carbon particles, whereupon PTFE is added and the mixture of the composite and the PTFE is then ground a second time and is thus homogenized.
