STONE CYLINDER THROUGH-FEED HYDRAULIC POLISHING MACHINES

open-end, with stone cylinder, with support cylinder with felt, complete with fittings, with low conveyor, with electric equipment, with safety device, with all electric motors, without Electro-exhauster.

Characteristics:

• Support structure, in welded steel, comprising boxed sides and connecting beams.
• Dynamically balanced polishing rolls, by means of adjustable counterweights on the flanges.
• Thermal expansion compensating device for the amber roll so as to ensure constant blocking on the shaft.
• Support cylinder covered with a high thickness wool sleeve and a rubber cushion which increases its elasticity and assures a safe transport and an uniform polishing.
• Hydraulic opening and closing with all components installed in protected positions, running on rolling bearings.
• Opening and closing pedal, with gradual control or two set positions.
• Hydraulically operated feed system with speed continually adjustable from 0 to 28 m./1'.
• Decimal regulation of thickness with read-off of value set.
• Device operating on both sides providing rapid adjustment by 3 tenths in either direction of the position of the support-roller in relation to the polishing roll.
• Automatic blending device both at beginning and at the end of each pass.
• Upper hide-retainer roller to ensure reliable feed with no effort from the operator.
• Total dust exhauster system with upper and lower suction intakes.
• Hide conveyor belt with option of hide offload to front or rear, hydraulically operated with speed automatically varied in relation to feed speed.
• Intrinsic operator safety devices throughout the processing zone with continual electronic monitoring of efficiency. The device opens the machine and stops the rollers by means of electro-magnetic disk brakes.
• Electric housed in sealed cabinet with auxiliary voltage 24 Volts, complying with international safety standards.
