The invention relates to a process for producing water-absorbing polymer particles, comprising the steps of: processing an aqueous polymer gel from polymerization of a monomer solution or suspension, drying the aqueous polymer gel in a conveyer dryer, in particular in a forced air conveyer dryer, wherein the conveyer dryer has a circulating conveyer belt and the aqueous polymer gel is conveyed on the circulating conveyer belt, and wherein the circulating conveyer belt is formed as a circulating plate conveyer belt, comprising a number of belt plates separated by a hinge line of a hinge assembly and each belt plate having a surface for receiving the aqueous polymer gel, wherein said hinge assembly comprises a knuckle joint (301) with the hinge line in form of a straight hinge line.

A compacting system compacts particulate matter in open-top railroad gondola cars rolling on rails. The compacting system comprises a compacting station adjacent the rails and a scanning system that scans the gondola cars as they move along the rails toward the compacting station. The scanning system transmits data of the gondola car to an electronic control system. The compacting station has at least one compaction member, e.g., a plate structure or a roller, configured to contact an upper surface of the particulate matter in the gondola cars. The electronic control system controls the compacting station so that the compaction member engages with and applies force to the upper surface of the particulate matter in the gondola car so as to compress the particulate matter in the gondola. A method for compacting particulate matter in a gondola car is also shown.

An ozone treatment apparatus for grain uses first and second storage bins and an auger conveyor for conveying the grain from a first end in communication with the bottom of the first bin to a second end that can be directed into either one of the top of the first bin or the top of the second bin. An ozone injector injects ozone into the auger conveyor for mixing with and treating the conveyed grain. In a first mode, the conveyor discharges the grain from the second end of the conveyor through a first discharge outlet into the first storage bin to recycle the grain during treatment. In a second mode, the conveyor discharges the grain through a second discharge outlet into the second storage bin once treatment is complete.
