PEZZOLATO ROTARY SCREENER L 4000

L 4000 is the Pezzolato rotary screener dedicated to the selection of wood chips. It is an essential professional machine, easy to use and maintain, with an excellent quality/price/performance ratio.
It is mounted on a particularly robust electro-welded frame, with the engine (electric or diesel) positioned at the front of the machine, together with all the hydraulic transmission parts.
The large hopper (2300 x 1200 x 600 mm) is equipped with a chain-link feeder belt and allows a large quantity of wood chips to be loaded in a single operation.
The power is transmitted by a chain, welded around the cylinder, and a gearbox with hydraulic motors. The screening cylinder, made of 5 mm thick sheet metal and with customisable holes size, can be easily changed by a single operator.
The rotation speed of the cylinder can be adjusted by the operator according to production requirements, allowing the machine to return between 15 and 35 cubic metres of screened material on an hourly basis.
The working length of the screening cylinder is 4000 mm and consists of two sections: a first part (length 1500 mm) with small-diameter holes to separate the dust, and a second part (length 2500 mm) with intermediate-diameter holes to separate the ‘screened’ part of the wood chips from the larger (oversized) elements that are ejected from the end of the cylinder.
Pezzolato screeners are widely used in the selection of wood chips to be burnt in automatic feed boilers: they separate, in a single passage, the fine parts or oversized flakes to obtain a product of homogeneous size.
In the stationary/electric version, the rotary screeners can be set up on feet or on a cement base; a mobile version, equipped with a trailer, will also be realised soon.
