MINE PRODUCTS
Industrial Dampers
AMD Co. supplies multiple products incorporating dampers or dampers as individual units. We offer the following products: Mine Door with Dampers, Damper Door, Industrial Dampers (single unit dampers).
Mine Door with Dampers:
- Dampers are installed into our traditional ventilation mine doors, so these doors can be operated like a traditional ventilation mine door (high cycles, high pressure, power actuation and automation).
- See “Mine Doors with Dampers” (link to mine door with dampers page).
Damper Door
- AMD Damper Doors are available in almost any size and can be configured in a single wing or dual wing design. Damper doors can be opened manually and will allow access where drop board regulators cannot.
- See “Damper Doors” here (link to damper door page already completed).
Industrial Dampers (single unit dampers)
Industrial dampers can be used for many different applications: damper walls, intake and exhaust fan dampers (at the raise), tunneling dampers etc..
- Offered in almost any size or configuration.
- Opposing blade or parallel blade designs.
- Manual or automatic.
Damper Actuation Options
- Manual.

Track Cleaners
At AMDr® our Model 75 is a rugged, heavy-duty Track Cleaner ready to remove iron, copper, coal, potash, and salt from your tracked mine. (This design was formerly called the Canton Track Cleaner.)
Designed to serve in a variety of underground mining environments, our Model 75 Track Cleaner operates while hitched to a locomotive. It cleans your mine track using two steps:
- Using the Forward Plows, the track cleaner scoops excess debris from the outside of the railway. Once set to the best position, the plows funnel the debris into the center area between the tracks.
- Between the rails is a Digger Plate traveling 1″ above the railroad ties when in digger position. The digger plate strips through any debris which has compacted along the tracks. Loosened material is funneled up the digger plate onto a gathering conveyor chain. The gathering chain conveys debris onto a boom conveyor and then into a receiving rail car being pulled by the Track Cleaner (coupled together).
Specifications on the AMD Model 75 Track Cleaner

Cable Molds
We design and machine in-house two different types of molds that are used in our CV machines. Molds are machined from 6061 aluminum using CNC machining equipment. All CV molds are fitted with hardened pins and bushings for alignment of the top and bottom halves of the mold.
Splicing molds are used to join two cables together or repair damaged wires within a multi-conductor cable.
These molds open up to a larger diameter in the center of the mold to accommodate the extra space required for the splice.
Repair molds are used to repair damaged outer jacket only. Repair molds have the same diameter of the cable being repaired all the way through the mold.
