Morbark introduces Vtection Vibration Detection System
October 6, 2021
Morbark recently introduced a new, patent-pending Vtection Vibration Detection System. The Vtection system monitors rotor vibration in their 6400X, 3400X, and 3000X series of horizontal grinders to reduce damage from contact with un-grindable objects or other causes of damaging vibration like an out-of-balance rotor, broken insert, or defective bearing. When coupled with Morbark’s Break-Away Torque Limiter, dual hammermill protection – both mechanical and electrical – is achieved.
To use the Vtection system, the operator sets an acceptable operating vibration level through the electronic controller. Since different feedstocks produce different vibration levels, the operator can quickly fine-tune the trip point to match the grinding application. Adjusting the trip point based on the feedstock can help avoid unnecessary stopping of the infeed from normal operating vibration.
Once the Vtection system is triggered, Morbark’s Integrated Control System (MICS) initiates several actions to remove the tramp material out of the rotor area. The sequence of these actions includes: reversing and stopping the infeed, bringing the engine speed to idle, disengaging the clutch, and a warning message is displayed on the MICS screen. At this time, the operator can inspect the grinder and remove the object that caused the trip before resuming operation.
With feedstocks ever-changing, the Vtection equipment modes allow the operator to have settings tailored to that day’s grinding application. The Vtection system will stay tied to those modes allowing the user to have various vibration profiles. The system cannot guarantee a machine is without a defect. Operators should always use caution after the system trips, and service work begins, as other components may have experienced damage.
Ship-out kits are available for in-field installations on preexisting 3000X, 3400X, and 6400X horizontal grinders. Please contact Morbark sales at 800.831.0042 or your local Morbark dealer (www.morbarkdealers.com) for additional information and pricing.
