PWM Powdermaster granular silage preservative applicator

The Powdermaster granular applicator is purpose built for applying granular additives to a range of different forages. The applicator consists of a rotor delivery unit mounted at the bottom of a high-density plastic hopper. The rotor delivery unit is controlled by Selmech’s basic controller to adjust the speed of the rotor, the additive is then applied to the forage via a gravity fed single 50mm diameter hose or three 25mm diameter PVC pipes. The Powdermaster is suitable for self-propelled and trailed forage harvesters, forage wagons and balers.

Blower attachment

In situations where gravity feeding of the additive is not possible or difficult to accommodate Selmech have designed a blower attachment option. This can be easily fitted to the Powdermaster applicator in place of the delivery hoses.

Hopper material

The hopper is manufactured from high density plastic to avoid problems associated with condensation and is available in 50kg capacity option or the lager 80kg capacity (typically 2x 20kg or 3x 20kg bags of additive respectively).

Output range (Output will depend on the volumetric weight of additive)

Basic PWM controller

The basic Powdermaster applicator is supplied with our own in cab variable speed controller that enables the operator to set the output of the applicator easily and make manual adjustments for varying crop densities. It has an LED fault indicator to warn of blown fuse or power supply issues. There is a boost button to run the pump at full speed for a short period if there is a temporary heavy crop density encountered. There is also an output for the addition of a thru beam crop detector. A guide calibration chart is provided to help set the required output with a range of different granular additives.

Features

Thru beam crop detector kit option

The Thru-beam crop sensor kit is an optional extra which is used to automatically pause the applicator when no crop is present. The kit consists of a sensor and emitter which are mounted facing each other on either side of the pickup. The emitter sends a red beam of light to the receiver on the opposite side, when this beam is intact it means there is no crop present so the applicator will not run. When the beam is broken by the presence of forage crop, the applicator will resume. This is particularly useful on round balers and baler/wrapper combos which have a lot of stopping and starting. It is of course possible to pause the applicator by pressing a button on the controller each time you want the pump to stop, but with the crop sensor fitted it is all done automatically which is one less thing to think about for the operator.
