A cross-contamination free and efficient laboratory sample grinder is disclosed which includes: a first housing unit having a plurality of pestle ejecting pins arranged in a fixed position, a second housing unit containing a planetary gear system connected to operate an array of mortars and pestles, and a third housing unit containing a single motor and controllers; when the first housing unit is in lock position with the second housing unit, and a third housing unit containing a single motor and controllers. The first housing unit, the second housing unit, and the third housing unit are geometrically configured and dimensioned so that when they are stacked on top of one another they are in lock position and consequently the array of pestle ejecting pins are lined up with the plurality of pestle ejecting pins.

A modular system and method for producing urea from bio-mass includes means and steps for “homogenizing” a biomass feedstock stream having components with different bulk density BTU content into a stream having a consistent bulk density BTU content. The steps include cleaning the incoming bio-mass feedstock stream to remove non-organic matter, blending the cleaned bio-mass feedstock stream to obtain a homogeneous blend having a consistent bulk density BTU content, and milling the homogeneous blend bio-mass feedstock stream to a predetermined size no greater than 12 mm.

A system for eliminating unexploded ordnance from a mixture. The system includes a separation plant, including a crusher, a magnetic separation station, and a screen plant. The crusher reduces the size of pieces in the mixture, the magnetic separator separates pieces containing a significant amount of ferrous metal, and the screen separates small pieces from larger pieces. The fine output of the screen is composed of pieces that are sufficiently small to pose little hazard; they may be further subjected to heat treatment. Large pieces containing ferrous metal, or large pieces containing nonferrous metal, may be explosive and are transported, using an unmanned machine, to an inspection plant where they are sorted and where any unexploded ordnance is identified and disposed of. The separation plant is sufficiently distant from the inspection plant that an explosion at the separation plant does not pose a hazard to personnel at the inspection plant.

The invention provides for method for forming an artificial turf infill material. The method comprises selecting from a zeolite ore a microporous zeolite mineral using a selection criterion on specific surface area of the mineral, thereby providing the artificial turf infill material.

A portable feed mill machine having a plurality of spaced-apart feed mills positioned on a wheeled frame such as a trailer. Any one of the feed mills may be taken out of operation for repair without the other feed mills being taken out of operation. The machine may have a plurality of mechanized devices rather than the feed mills.

The present invention relates to a process for producing a nanocellulosic material based on the use of fractioning of cellulosic pulp stream from pre-treatment or mechanical defibrillation (partially refined/defibrillated pulp) in combination with stages of mechanical defibrillation, in which both the accept fraction and the reject fraction can be conveyed to stages of consistency adjustments so as to precede another distinct defibrillation stage. For example, if the accept is conveyed to a consistency adjustment preceding a second defibrillation stage while the reject is conveyed to the other independent stage of consistency adjustment to return to the first stage of mechanical defibrillation.

The invention relates to an installation for producing glued plant particles, in particular from annual plants (e.g. straw), in order to produce boards, e.g. fibreboards or chipboards, having at least one comminuting apparatus (2) for comminuting plant-based starting material to form scatterable plant particles, and having a gluing apparatus (15) for gluing the plant particles. This installation is characterized in that at least one first screening apparatus (3) for separating silicate particles from the plant particles is arranged between the comminuting apparatus (2) and the gluing apparatus (15).
