Rubble Master has new drive

Crushing Static & Mobile / November 2, 2019

Austrian compact mobile crusher manufacturer 6484 Rubble Master has chosen the VACON 100 X AC drive from Danfoss Drives to control its new RM V550GO! mobile crusher.

Until recently, Rubble Master had used a maximum 11kW custom-made drive to control the motors of the vibrating conveyor of their crushers. However, for its V550GO! mobile crusher design they needed a 15kW drive, capable of withstanding demanding environments.

Gerald Hanisch, chief executive officer of Rubble Master, said: “As our mobile crushers are used all around the world, we needed a robust drive which endures a wide range of operating temperatures and is able to withstand dust, moisture, humidity and vibrations. Additionally, the drive must tolerate high altitudes.”

The VACON 100 X drives in the new RM V550GO! provide parallel control of two unbalanced motors. The motors run a vibrating conveyor which transports the material to be crushed to the crushing section. A CAN bus (Controller Area Network) is used for communication with their internal control system.

Rubble Master is also considering replacing the customised solution used in their existing products with VACON AC drives. Additionally, they’re also planning to start using VACON AC drives to control other parts of their machines.

The VACON 100 X represents the concept of decentralised drives: products that can be mounted directly on the motor or machine or wherever the most convenient location for the drive is. Significant savings can be achieved in cabling costs, space and energy when the installation does not require the drives to be mounted in a separate electrical room or enclosure.

“We received all the service and support we needed during our testing and piloting phase, and we are very happy and satisfied with the solution,” said Hanisch.
