The PS series pre-shredder is a versatile and robust machine with low management costs. Available with rotor dimensions from 600 to 1200 mm and powers from 11 to 55 kW. The pre-shredder PS is equipped with a classifier screen and a hydraulic drawer. It carries out primary shredding of plastic materials, metal materials, copper cables, aluminum profiles and metal scrap.


The CSR pre-shredder series is a superior machine for heavier duty jobs. This pre-shredder is also equipped with a classifier screen and hydraulic drawer. The CSR pre-shredder is available with 55 - 200 kW power and with rotor dimensions from 900 to 2000 mm. The CSR pre-shredders are equipped with electric or hydraulic drive on the larger models. These are robust machines with reversible knives mounted on holders for a simple and quick maintenance.

primary shredders

C-Series primary shredders. These are machines equipped with a hydraulic drive suitable for heavy-duty use. All C-Series pre-shredders are equipped with a classifier screen available in different sizes to get the desired size in one step. The production parameters can easily be changed and optimized by the PLC to improve to process. The management PLC can vary the rotation speed of the rotor and the response times of the hydraulic pusher. The C series pre-shredder is an extremely versatile machine that adapts to the processing of different and heterogeneous materials: end-of-life tires (ELTs), aluminum waste from collection, aluminum profiles, copper-aluminum radiators, electrical and electronic scrap, (WEEE), armored cables, municipal waste (MSW treatment) and industrial waste in general. The pre-shredders of the C series are available with outputs from 150 to over 400 kW and with rotor dimensions from 1600 to 2800 mm. The C-series shredders can be manufactured in different sizes and capacities according to the end user's specifications.

pre-shredder fast

The MFS pre-shredder is the only shredder in the series without the hydraulic drawer. The pre-shredder is equipped with a high-speed rotor, which enables fine shredding even with tough metal fractions. The MFS pre-shredder refiners are available in three versions with a power of up to 200 kW and a rotor length of up to 1800 mm. The MFS pre-shredder is particularly versatile and useful as a pre-shredder, it can be used in WEEE recycling plants, copper recycling plants, toner recycling plants, solar panel recycling plants, scrap and waste recycling plants.
