This occurs at certain belt speeds, idler spacings, conveyor load and belt tensions. Helix delta-T6 can calculate whether there will be belt resonance like this on conveyor sections and if present then you can alter the design to ensure this bunching and severe structural vibration does not occur on your conveyor.

Belt Conveyors for Bulk Materials Practical Calculations

All conveyors require an additional belt tension in order to allow the pulley to drive forward an effective tension without slipping. In a case of a simple horizontal conveyor T1 is the sum of the effective tension Te and the slack side, the tension T2. T 1 = T e + T 2 =

 The belt widths are as follows: 18, 24, 30, 36, 42, 48, 54, 60, 72, 84, and 96 inches.  The width of the narrower belts may be governed by the size of lumps to be handled. Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt.

Idler spacing must be selected on the grounds of available belt tension, fatigue life of the idler bearings, and structural considerations. The upper spacing limit should be set at 2200mm. Account should be taken of four and five roll sets, but no significance can be attached to the claim that four and five roll idlers give better belt life.

Minimizing Spillage With Troughed Belt Conveyors

A belt tension that is too high pulls and stretches the conveyor belt, preventing it from troughing properly and therefore making it unable to contain material as well. If belt tension is too low, the belt will sag between idlers, allowing material to fall off the sides.
