The SPR Bag Opener is a pre-shredder equipment developed, manufactured and marketed by SPR Group specifically designed to tear bags of all sizes without damaging their content and that reach both the Municipal Solid Waste (MSW) treatment plants and sorting plants for Light Packaging (LP).
Simplicity and efficiency are the main features of the SPR Bag Opener, whose main function is to facilitate the downstream phases of the material recovery process.
How the Bag Opener SPR works
The material falls onto a rotor that incorporates interchangeable blades that are arranged helically. The shaft is of slow rotation (with possibility of regulation from 5 to 8 rpm), specific to open and tear the material, which is led up to a static counter-blades installed in a damper.
This anti-blade damper of the machine is easily hydraulically adjusted for maintenance. The distance between the interchangeable blades and the counter-blade holder is adjustable in 5 positions (from 0 to 200 mm), in order to be able to adapt to the different types of waste to be treated according to the treatment plant where the SPR Bag Opener equipment is installed.
The interchangeable blades of the rotor and the counter-blade holder are manufactured with an extremely wear-resistant layer. In addition, they are arranged in such a way on the shaft that when the rotor is rotated at low revolutions all the bags are opened. After the opening of the bags, the material in the bags falls to the bottom of the equipment on top of a feeding belt that carries the residue to the next stage of the treatment process.
Waste and advantages of crushing equipment
The SPR Bag Opener is a pre-shredder equipment designed to open and empty bags of all sizes with high efficiency, which makes it an equipment trained for its application in Municipal Solid Waste (MSW) treatment plants, Light Packaging (LP), Refuse Derived Fuels (RDF), Municipal Organic Solid Waste (MOSW) and Medical Waste.
This pre-shredder equipment, in addition to having a certified efficiency of 98% in the opening of bags, is able to work offering a maximum performance of up to 40 tons per hour. Its low maintenance cost and easy execution, added to the high durability of the equipment thanks to the low speed of the rotor and the protection against dirt and leachate by means of the planetary reducer inside the rotor, make the SPR Bag Opener a highly reliable equipment. In addition, it has an automatic cleaning and anti-jam cycle and it is possible to manage the equipment and its maintenance by remote control via 3G modem. Its sturdy construction allows to dispense with anti-vibration or sound reduction measures.
