Specialty Motors for Cement & Aggregates

Specialty Motors for Cement & Aggregates

Reliable and Efficient Motors for Extreme Conditions in Cement Plants

Efficient Motors and Reduced Downtime

Louis Allis partners with cement plant owners, operators, and facility managers to ensure their motor equipment is operational and working as efficiently as possible. We understand the costs of running heavy machinery or taking a plant offline, especially with decreasing margins from production to market price.

Every Motor Application

We’ve been manufacturing motors for over 100 years. Our large, specialty motors are built-to-last and run as efficiently as possible. Today, we manufacture, repair, and maintain motors found in crushers, raw mills, kiln drivers, clinkers, ID fans, ball mills, and finishing mills. As part of the Worldwide Electric Corporation, we can also offer standard, off-the-shelf rock crusher motors for use on conveyors that move materials throughout a cement facility and motor controls, such as Variable Frequency Drives and Motor Soft Starters.

Heavy-Duty Motors for Cement and Aggregates

Crushing

The primary crusher breaks down base materials, such as limestone, shells, or clay. Once crushed, it is stored until needed. Additional materials, such as chalk, sand, fly ash, or iron ore, may be introduced and broken down. Plants often use two crushers, a primary that reduces the initial size and a secondary crusher that takes products down to 1” or smaller. Specialty motor applications include:

  • Feeder Motor | AC/DC
  • Reclaimer Motor | AC
  • Crusher Motor

 

Raw Mill

The Raw Mill takes dry materials and crushes them into a fine powder. Water is added to the mill if a wet slurry mix is required. Specialty motor applications include:

  • Feeder Motor | AC/DC
  • Air Separator ID Fan Motor | DC

 

Preheater and Kiln

Materials are fed into the preheater and kiln on conveyors or bucket elevators for pyroprocessing. Fuels are also delivered to the Kiln via conveyor. Specialty motor applications include:

  • Feeder Motor | DC
  • Preheater ID Fan Motor | AC/DC
  • Kiln Motor | DC

 

Clinker Cooler

“Clinker” from the Kiln needs to be cooled. It is moved on grates or conveyor belts to storage in silos or warehouses. The abrasive, hot clinker can build up and damage equipment. Specialty motor applications include:

  • Cooler Grate Motor | DC
  • Exhaust Fan Motor | AC/DC

 

Conveying and Feeding

A cement plant makes extensive use of belt and chain drive conveyors, rollers and bucket elevators to move materials from or feed materials into the process.

  • Heavy Duty Rock Crusher Motors
  • Gears and Reducers

 

Finish/Ball Mill

Clinker nodules are moved from storage to the finishing mill and ground into the final cement powder. Specialty motor applications include:

  • Roller Press Motor | AC/DC
  • Feeder Motor | AC/DC
  • Separator Motor | DC

 

Ventilation and Air Handling

Cement production uses ID fans driven by large motors to feed the preheater and kiln, removing hot and dusty gases from the process or for essential ventilation. Specialty motor applications include:

  • Clinker Cooler ID Fan Motor | DC
  • Clinker Compartment ID Fan Motor | AC/DC
  • Exhaust Gas ID Fan Motor | AC/DC
  • Pack House Vent Fan Motor | DC

 

Storage and Packing

The final cement product is moved pneumatically in pipes. Bagging operations in a “pack house” use conveyors to move and ship bags of cement.
