Operation And Feed Rates - SEM 250 Operation And Maintenance Manual

Operation and Feed Rates

Please read this section carefully. Most problems occur during the first hours of operation. Most
problems can be avoided and/or eliminated by a careful review of the operating, maintenance,
and recommended service period instructions.
A. The Model 250 has been shipped complete, tested, and is operational when received.
B.
The Model 250 requires a 20-amp dedicated electrical line, equipped with a 20-amp
receptacle and a separate 115V circuit receptacle for the vacuum unit.
C.
Once positioned, verify that the vacuum is connected, and that all access points are closed. Turn
the toggle switch to the "ON" position and the unit will start. Both the disintegrator and the
vacuum should come on together. In the event that the vacuum does not start, locate the power
button on top of the vacuum to start the vacuum.
D. The Model 250 was designed to destroy key tape, and optical media (CDs/DVDs/BDs) at a rate
shown below. As with any type of machinery, it can be overloaded or jammed if overfed. The
product destruction rate depends on the material type, material size, and desired deestroyed
particle size. When feeding, use the concept of "less is more". By feeding the unit with less
volume more often will result in steadier and better feed rates, resulting in reduced operating
costs.
The Model 250 is not a shredder, but a rotary knife mill, which dictates how the unit is fed and the rate
it can be fed. Again, the rule of thumb is "less is more" creating steady output without over feeding.
Looking at the top of the Model 250 you will notice that there are two feeding slots, the smaller feeding
slot is for key tape while the other is for optical media. Key tape media can be put on the spool
attachment on the top cover of the cutting chamber.
Maximum Feed Rates
•
Optical media with a 3/32" dia. screen: eight pieces per minute
•
Optical media with a 5/64" dia. screen: four pieces per minute
E. When destruction is complete, allow the Model 250 and vacuum to operate an additional 80
seconds after the last fed piece of material. This will prevent build up in the cutting chamber
area and evacuation line, ensuring proper operation for the next user.
F. The Model 250's waste collection bag must be periodically emptied for proper operation.
