Firstgrade recognise that the key to efficient waste processing is a uniform feed rate, to achieve this we can offer from a large range of feed hoppers, using either a positive drive system with chain and slats below a belt offering a powerfull non-slip drive that requires no belt tracking or tensioning and can be run at very low speeds, to our virtually indestructable vibrating feeders built with 1/2inch thick steel to take the abuse that can come with the waste industry. Friction drive hoppers are also available.
