A stirred ball mill including a grinding container, in which an agitator shaft having grinding elements is arranged, whereby a grinding chamber is formed between the grinding container and the agitator shaft, into which chamber the grinding elements extend and into which at least one inlet duct for grinding material opens and in which a dynamic separation device for grinding bodies is provided, the separation device having recesses for feeding back the grinding bodies, and in which the agitator shaft has at least one recess, which widens the separation device and extends in the axial direction into the grinding chamber for improved distribution of the grinding bodies in the grinding chamber.

An agitator ball mill with a fluid circuit, which includes a grinding container and a casing container disposed around the latter uniformly spaced apart axially with a cavity formed between the containers. The fluid circuit is led at at least one flange through at least one flange lead-through introduced there, wherein a first opening of the at least one flange lead-through is constituted in a side wall of the corresponding flange lying orthogonal to the outer surface of the casing container.

A grinding circuit comprises a grinding mill having a shaft in a grinding chamber, a cyclone for receiving circuit feed material and for feeding said circuit feed material further in the grinding circuit, and monitoring devices. The grinding mill process comprises pumping circuit feed material from a feed tank to the cyclone upstream of the mill, and pumping the circuit feed material forming slurry into the grinding mill for grinding the slurry into finer particles. The method of controlling the grinding mill process comprises monitoring at least one operational parameter, and controlling particle fineness online by adjusting at least one of the following operational parameters: flow rate of the circuit feed material, density of the circuit feed material, shaft speed, filling rate in the grinding mill, milling density and retention time.

Disclosed herein are devices, apparatuses, and methods for grinding of samples. A method includes securing a sample vial in a holder attached to a connecting linkage, the sample vial having a grinding media in the sample vial. The method includes rotating a crank that is operatively coupled to a proximal end of the connecting linkage at a proximal pivot point so that the proximal pivot point undergoes rotational motion. The method includes restricting a distal pivot point of the connecting linkage to a linear path, the distal pivot point near a distal end of the connecting linkage. A result being that the sample vial undergoes a combination of rotational and linear motion.

A grinding mill for pulverizing material includes a platform having an upper surface and defining a recess having a floor, the recess configured to seat a dish in which the material is disposed, and a movable securing frame that is movably connected with the platform, the frame including a lift support having an upper surface that is movable along a path from a first location that is beneath the floor of the recess, through the recess, to a second location that is coplanar with the upper surface of the platform. A motor configured to cause oscillation of the platform and the movable securing frame can be used. A method of using the grinding mill can include placing a dish above a recess defined by an upper surface of a platform, and lowering the frame with respect to the platform, thereby seating the dish within the recess.
