APPLY's automatic sack slitting machine enables hands- free cutting of sacks containing dry chemicals, and automatic feeding into a mud mixing hopper by a screw conveyor. Various models can be delivered with footprint and parallel or sequential operation.
The machine SSGD is equipped with a gravity drum and has a robust and well proven sack cutting principle which follows gravity force to feed the sacks over rotating saw blades, and a rotating drum to separate the dry chemical from the split wrappings of the sack.
This machine is a typical part of a mud additive plant, and includes a lifting table to align the sacks with the same level as the feeding table. Other machines in such a plant are a big bag slitter for sacks of 1m3, several mud hoppers based on venturi eductors, a dual liquid additive skid, and a couple of bulk surge tanks for dosing of bulk chemicals as barite and bentonite.
One model of the SSGD machines is equipped with a front loading system of the sacks, while another similar model is equipped with a side entry for feeding the sacks over its roller table. The drum itself has a length of 200cm .
