PRE-SHREDDERS

M&J, formerly known as Metso, is crushingly reliable when it comes to the supply of stationary and mobile shredding equipment. M&J Shredders offer a unique, patented cutting-table and knife designs that has made the company a leading producer of primary shredders. Known for their pre-shredding, shredding, crushing and grinding abilities, these rugged units can be found in many plastic recycling and incineration plants, hazardous waste processing facilities, transfer stations, C&D recycling plants, landfills, RDF/SRF/PEF production facilities and many more processes. M&J Shredders can be found in over 500 installations around the globe.

M&J is expanding its waste recycling product range with the launch of the new M&J K-series pre shredder machines. The first two models will be M&J K160 and M&J K210. The new competitive models provide a low cost-per-ton with high reliability, ease of operation and great flexibility for various waste types and with a design optimized especially for sites with a 5-45 tons per hour production requirement.

The new shredders come with the wide variety of proven knives developed by M&J to accommodate clients’ specific needs. With the open cutting table design, operators do not need to pre-sort the waste being loaded into the shredder; this translates to higher capacity with less manpower and fewer breakdowns.

M&J K-series – Improved capacity with a longer lifetime and lower cost

• The unique bi-directional shredding system (both synchronous and asynchronous) with two shafts provides superior performance with all waste, resulting in unbeatable uptime
• The proven knives geometry reduces the risk of wrapping on the shafts, resulting in less bridging and fewer cleaning stops to improve capacity
• The modularity ensures that only relevant components need to be maintained, ensuring a longer lifetime with lower operating costs
• The M&J K-series pre-shredders have a robust and proven construction and are easy to access, making maintenance fast and service costs low

The M&J 2000S is a single-shaft stationary shredder that features PLC controlled automatic reversal and shredding in both directions. This innovative feature prevents material wrapping around the shaft, helping eliminate bridging issues and preventing breakdowns. This machine uses the same main components and shredding power as its big brother the 4000-S.

An open cutting table and a shredding zone that is both long and wide make this mid-size model ideal for processing inputs such as MSW, bulky waste, industrial waste, C&D waste, etc. Depending on the type of waste the cutting table specified and the feed set-up, throughputs of 5–70 tons/hour are within easy reach.

M&J Recycling has a long tradition of building world-class pre-shredders. The M&J P250 is no exception. It is based on thoroughly tested technologies and, at the same time, sets the course for the next generation of pre-shredders with its modular design that makes service and maintenance easier and cheaper than ever. With the M&J P250, you get a highly efficient pre-shredder that can be matched to your specific needs. And should your waste types change in the future, our service staff can quickly change the configuration. When we promise you unparalleled production uptime and hefty savings on your operating budget, we really mean it. All vital parts of the M&J P250 can be quickly disassembled. This provides significant time and cost savings when it comes to service and maintenance as well. The P250 is available with an E-drive or a hydraulic drive.

• Better welding access for hardfacing on cutting table
• No need to disconnect hydraulic system during maintenance
• Targeted replacement of the parts that are worn (and only those)
• No need to disconnect the high-pressure hoses
• Drive module is easily disconnected via nuts and bolts
• Easy to adapt the machine to future needs

The M&J P250 is the mid-sized model of the M&J PreShred stationary pre-shredder family. It can process various waste types such as bulky waste, commercial and industrial waste, municipal solid waste, construction and demolition waste, biomass, wood, as well as baled materials. The pre-shredder is generally used in refuse-derived fuel (RDF) production, biomass processing, waste-to-energy plants (WtE) and in mechanical biological treatment plants (MBT).

The M&J P250 features an open cutting table that allows stones and other hard particles like metals to fall through the cutting area. The open cutting table design and bi-directional shredding system increases safety and reduces the risk of malfunctions that may hinder operations.

All knives and parts exposed to wear on the M&J P250 are made from wear-resistant steel, ensuring continuous and long-lasting performance. Bolts and bearings are conveniently mounted away from the cutting area, allowing for easy access and maintenance to reduce costly downtime.

Go green with E-drive

For certain waste type you should consider the many benefits of choosing the E-drive solution for your M&J P250. E-drive handles the task of shredding MSW, light C&I and waste wood as efficiently as a hydraulic drive. Only, it has the added advantage that it is far more energy-efficient and thus provides you with even bigger savings on your operating budget.

E-drive consumes up to 50% less energy during operations compared to hydraulic drive and enables you to execute the green transformation.

E-drive makes significantly less noise than a hydraulic drive* and therefore results in a pronounced improvement of the working environment for your employees. This can help retain employees – and attract new ones.

The M&J 4000S stationary shredder is designed to meet the special needs of plants in which the incoming material is extremely varied in both size and composition, and may also contain unpredictable components. The combination of a large cutting table and a twin-shaft shedding system makes it possible to shred almost any kind of material and that there are no problems with bridging.

The two extremely powerful shafts run asynchronously and in both directions. The power is transmitted via a double hydrostatic transmission that makes sure the machine provides full power right from startup, and takes full advantage of all the power for shredding. Depending on the machine configuration capacities of 10-100 Tons/hours are achievable.

The M&J 6000S is one of the largest stationary shredders currently available in the world. This giant shredder is equipped with two 4 meter long shafts and an exceptionally large shredding zone that is approximately 7 m3 m in size. Together, these features make this top-size unit ideal for shredding unusually bulky or very heavy inputs in large volumes.

Depending on the machine configuration and the waste material capacities of 20-200 Tons/hours are achievable.

Say goodbye to manual labor and the risks involved in cutting baling wires in the Plastic Recycling Industry!

M&J Shredders are ideally suited as bale breakers for the PET and HDPE bottles recycling process.  Thanks to the unique cutting table design it is possible to load whole bales with wires attached.  The equipment breaks the bales, deliberates the bottles without the risk of cutting them into small pieces.  This ensures that the bales are well declumped allowing a continuous flow for the downstream equipment.

Meanwhile, the wires will be cut into smaller pieces and can be removed by magnets right after the bale breaking operation.

Technical Highlights:
• Load bales WITH wires attached – No need to cut wires before loading
• Deliberates bottles without the risk of cutting them into small pieces
• Continuous flow of materials for better downstream processing
• Manual labor and risk to workers reduced to a minimum

Applications:
• PET, HDPE bottles, Recycling, AG-film recycling
