Page 3: Disintegrator Safety Rules
SAFETY GLASSES OR A FACE SHIELD MUST ALWAYS BE WORN when operating or servicing the machine. Although SEM machines are designed for the maximum in fly back control, caution must be used when operating near the area of the hopper feed opening in order to guard against unexpected material fly back. -
Page 4: Introduction
Evacuation General Description SEM disintegrators are designed to uniformly and consistently reduce the size of waste products through a user selected sizing screen. The rotor on which the cutting knives are mounted is a fabricated, steel unit supported by bearings mounted outside the cutting chamber. -
Page 5: Installation
All non-painted items subject to corrosion are coated with a quality rust preventative and the machine is then covered with heavy duty polyethylene to protect it from moisture and dirt. SEM Disintegrators are normally shipped completely assembled unless the size of the machine or an agreement for special shipping arrangements causes partial disassembly. - Page 6 SETUP Make certain the floor is clean, level, and free of obstructions before placing the machine into position. Open the machine by loosening the hex coupling nut(s) at the front of the machine enough to allow for rotation of the threaded swing bolts out of the clamp(s). Visually inspect the hopper in-feed opening to ensure that no stray packing material or debris is present.

Page 12: Changing Knives
Inspect knives weekly and sharpen after every 80-100 hours of use. Knives may be sent to SEM or a capable machine shop in your area for sharpening. When sharpened, the rotor knives must be sharpened as a set to maintain consistency in tolerances between the bed knives. If knives are badly nicked or damaged, they will function after sharpening if 75% of the cutting surface is effective. - Page 13 The general rule is to place a rotor knife and bed knife back to back as shown above and measure the total distance equal to dimension A above.
