OSCILLATING SCREEN - DPO
Demuth oscillating screen is of an extremely sturdy construction and has an easy maintenance concept. Manufactured in laminated profiles with square section and structural quality plate, features welded diagonal crossbars that provide an excellent stability. The maintenance and cleaning services are made easier by the front opening covers, which also allow a quick change of the mesh.
An eccentric adjustable weight system installed on a vertical shaft on the screen center guarantees its exact oscillation which, combined with different revolution, frequency and amplitude, may adapt to any kind of chips. The screen meshes can be easily replaced in case of changing the selected chip sizes or for maintenance purposes
Suspended by steel cables (plus auxiliary safety cables), the screening is performed in an efficient, silent and precise way. The sturdy sustentation beams, supported by concrete columns, do not allow vibrations to be transfered from the screen to nearby facilities.
The screen meshes can be easily replaced in case of changing the selected chip sizes or for maintenance purposes.
Deflection monitoring system of cables. Turns off the screen in case of breaking and / or displacement of the main support cables.
The smaller chip than the first perforation of the mesh screen classification are recorded on the second and third screen to retain and discharge those with dimensions acceptable for the process. Have the oversized chips remaining in the first screen are removed by appropriate and picked out, to return to the initial process of selection.
The quality of the selected chips has a direct effect on the final pulp production. Therefore, the efficient and quick chip selection is essential for increasing the productivity.
The chips are thrown on the first mesh deck by a discharge control chute, optionally supplied with a flow-equalizing worm screw
