A support, suspension, drive, traction and position control system comprised of mechanical, electrical, and hydraulic components integrated with computer controls for the rotation and maintenance of the operation of various types of rotary equipment including kilns, calciners, dryers, grinding mills, ball mills, and dissolvers. Further provided are methods for the use of the support, suspension, drive, traction and position control system and hydraulic components disclosed herein integrated with computer controls to rotate and maintain the operation of various types of rotary equipment.

The disclosure is directed to a sample preparation apparatus for grinding or homogenizing test samples. More specifically, the disclosure relates to grinding samples using rotational and linear motion. Grinding samples can be accomplished with an apparatus with a slider-crank mechanism that is attached to an oscillating connecting linkage. The amplitude of oscillatory motion can be greater than or equal to a length of a sample processing chamber.

Provided is a double-sided, axial flux gearless mill drive for a mill system that includes a radially-extending rotor assembly fixedly connectable to a mill drum of the mill system. A stator assembly of the gearless mill drive includes a first stator located axially adjacent a first annular surface of the rotor assembly and a second stator located axially adjacent a second, opposite, annular surface of the rotor assembly.

A method for starting a grinding tube with an assigned drive device, wherein during the operation of the grinding tube a grinding mode and a charge release mode can be set such that a particularly reliable monitoring of the state of charge located in the grinding tube is ensured, where the grinding tube is rotated and, at a first rotational angle, a first actual torque is detected, a setpoint torque is calculated for a second, relatively large rotational angle based on the first actual torque, an actually occurring, second actual torque is detected when the second rotational angle is reached, an investigation is performed to determine the difference of the second actual torque from the setpoint torque, and the charge release mode of the grinding tube is set when the second actual torque is within the threshold range, otherwise the grinding tube is operated in the grinding mode.

Grinder systems and methods for grinding a sample in a sample block are provided. One example grinder system includes a cylinder and a piston positioned in a bore of the cylinder and configured to move along a longitudinal axis of the cylinder. A first end portion of the cylinder is configured to couple to a sample block. A first air port is disposed adjacent the first end portion of the cylinder, and a second air port is disposed adjacent a second, opposite end portion of the cylinder. A controller is configured to control air pressure in the first and second end portions of the cylinder, via the first and second air ports, to thereby linearly move the cylinder in a first direction and the piston in a second, opposite direction to agitate a grinding device in the sample block to grind a corresponding sample therein.
