The Balkan Bale Opener, besides having a superior opening and mixing performance, has also excellent cleaning properties for cotton with help of the adjustable grid system underneath each of the two openers. For synthetic fibers, there is only one opener, which executes the opening process without damaging the fibers. As there is not much need for cleaning with synthetics, the grid system has been omitted. The Bale openers, which can be manufactured in 1,000 and 1,200 mm widths, have a high capacity.

The material is placed onto the moving band in front of the Bale Opener. The band feeds the material to the storage chamber of the Bale Opener, which is controlled by a photo cell, until it is full. The second band beneath the storage chamber starts moving on request, and the spiked band opens the material and moves it to the opening cylinders. The feed rate of the material from the spiked band can be increased or decreased with the use of a frequency controlled motor.

In order to avoid metal particles that might be mixed up with the material, and to protect other machinery on the line from damage, it is advisable to place a BALKAN Seporamat (heavy particle retainer) or a magnet at the exit point of the Bale Opener.
If needed, the Bale Opener may be fed with a BALKAN Condenser, which is mounted on the Bale Opener, This enables pre-mixing with other kinds of fiber, prepared elsewhere.
Bale Openers can be manufactured with automatic waste collectors upon request.
· Capacity to gin over 2 bales per hour on American Pima and over 1 bales per hour on upland cotton.
· Improved feeder design allows intensive seed lock separation for highest ginning capacities. Inclined spiked cylinders rotate over grid screens inside the feeder.
· Standard 15" diameter 40" wide ginning roller.
· Easy adjustment to maintain uniform pressure.
· Heavy steel plate gin end heads.
· Optional Microprocessor-based control system to modulate seed cotton feed to produce a pre-selected load level on the rotary knife. A power transducer is used to measure the load on the rotary knife motor. The control system not only compensates for differences in the trash and moisture content, but also allows a higher ginning rate, and prevents gin stand choke-ups.
