It is often said that the iris inspired the French fleurdelis, though without any serious evidence. [clarification needed] The case of the fleurdelis is deeply scrutinized by M. Pastoureau [pst98] in a welldocumented 16page text.[clarification needed] Whether the fleurdelis was inspired by a real iris, broom, furze or lotus is not the Law of 16 May 1991 the iris flower was ...

The prototype mill has its front side made of transparent glass in order to be able to visually examine the behaviour of the ball batch while the mill is rotating. The idea behind this type of arrangement is to create an exact model of the prototype mill for the DEM simulator and then compare the results while running the simulator and the ...

CNC milling is a subtractive manufacturing process. It starts by fixturing a block of metal or plastic material inside the CNC mill. Using Gcode, the CNC machine is programmed to rapidly mill out parts from the block of raw material. Our 3 and 5axis CNC machines are equipped with various toolsets to maximize efficiency and production speed.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
