Manufacturers and Suppliers of Laboratory and Light Industrial Mills & Crushing Machines
For de-lumping and pre-crushing prior to processing or finer grinding.
Features include:
This rugged, slow-running mill is equipped with either a single or double roller shafts fitted with crushing cams. The cams rotate between crushing and stripping combs. Different shaped crushing elements are available depending on material.
OPERATING PRINCIPLE /CONSTRUCTION The crushing cams of wear-resistant steel are mounted on the roller shaft in staggered positions, accurately spaced so that they pass between the crushing and stripping combs which are mounted laterally on opposite sides of the inner housing. Both sets of combs are identical in design but have different functions. The bearing plates at both ends of the housing accommodate the roller bearings, protected by radial seals, in which the shaft rotates. The shaft apertures in the end plates are protected by PTFE seals pressure-proofed to 0.5 bar, IP54. The second shaft of the Double Roll Crusher is driven by grease-lubricated gear wheels on the outside of the housing. The standard crushers are driven by a hollow shaft worm reduction unit with an integral torque limiter from a flange mounted motor. The torque limiter has the ability to stop rotation of the crusher shaft whenever the stall torque exceeds the calibrated value, thus safeguarding the transmission components if hard tramp material enters the crushing chamber. These units are ideal for fitting into process lines and are held on by the inlet and outlet flanges and therefore do not require any bulky support frames. The welded housing is box-shaped, accommodating either single, double roller shafts, the crushing cams, the crushing combs and the stripper combs. Standard models single and double are carbon steel.
Ideal for fitting into process lines or as a stand alone machine
