MUST SEE EXHIBITS AT AGG1 2019 GRIZZLYDRIVE For the past 35 years VAN DER GRAAF has been designing and manufacturing drum motors for an array of industries such as food processing courier postal parcel airline baggage handling pharmaceutical automotive and other applications that utilize belt conveyors to move or process products Among the most demanding conveyor operating environments are aggregate and mining applications Conveyor drives required to perform under abrasive dusty and high vibratory conditions can shorten the life of electric motors gear reducers bearings sprockets chains and V belts The mining and aggregate harsh and demanding operating environments and high production demands pose many challenges among which is motor and gear failure Failure is mainly due to abrasive dust in coal mines fine powdery dust in limestone quarries abrasive steel particles in iron ore mines as well as extreme belt tension Although the drum motor has been used extensively to drive conveyor belts it has not been used to a great extent in those industries because the standard design did not address the operational conditions that exist in mines and quarries The engineers at Van der Graaf have completed extensive research and development in the last 5 years to produce the all new GrizzlyDrive design drum motor which addresses these industry specific operating challenges The GrizzlyDrive is a different kind of drum motor It has been designed to reliably perform and operate in very harsh environments and demanding conditions Currently GrizzlyDrives operate from the extreme cold temperatures of Labrador to the extreme hot temperatures of San Antonio All components of the drum motor are protected inside the drum The robust mechanical seals are designed to prevent abrasive dust and water to penetrate the unit The massive end flanges on the GrizzlyDrive are engineered to deflect debris and rock overspill and inhibits accumulation to occur between the drum motor and conveyor frame The heavy duty bearings have been designed for high static and dynamic rating to absorb heavy shock loads and high belt tension The planetary and coaxial gear configuration design can absorb the high starting torque 240 produced by the high torque design C electric motor that is able to start the conveyor under full load conditions The electric motor windings are manufactured with heavy duty magnet wire and encapsulated via the vacuum pressure impregnation VPI process to withstand vibration and shock loads The patented IronGrip high performance lagging is engineered for harsh and vibratory applications It has sections of metal bars either straight or chevron pattern located between the vulcanized rubber segments with or without ceramic tiles to absorb the shear loads produced by the belt which increases durability and lifespan The GrizzlyDrive drum motor is built like no other designed exclusively for mining and aggregate applications are available from 85 diameter 5 hp to 42 diameter 500 hp Van der Graaf BOOTH 39002 VAN DER GRAAF 13771 Cavaliere Drive Shelby Township Michigan 48315 PHONE 888 326 1476 EMAIL info@ vandergraaf com WEBSITE www vandergraaf com FACEBOOK VanderGraafdrummotors INSTAGRAM _ vandergraaf GOOGLE u 0 VanderGraaf LINKEDIN company VanderGraaf TWITTER _ VanderGraaf YOUTUBE c VanderGraafInc S28 PIT QUARRY February 2019 pitandquarry com ALL IMAGES VAN DER GRAAF
