    If your operation screens lighter, wetter materials – mulch, topsoil and compost – a trommel screener is the way to go. The constant tumbling action stirs up material over and over, fluffing it, adding air to lighten it, and keeping it in contact with the rotating mesh longer. This action allows more material through faster and easier
