Linka® Twin Shredder system - type 120

Linka Energy’s shredding system (TWIN) is a well-proven straw shredder, originally designed, developed, and produced in the mid-1970s, based on the experience Linka has gained over many years of working with biomass.

Since then, in 2009, the TWIN technology has been refined and developed into the shredding system we have today, which we proudly consider one of the best straw shredders in the world.

The straw shredder’s power consumption is the lowest on the market, making it highly attractive to energy-conscious district heating plants, industry, and the biogas sector (for straw processing).

The LINKA TWIN 120 shredding system can handle a wide variety of straw types, such as seed grass, rapeseed, wheat, rye, oats, and similar.

The system can be combined with an automatic crane system to feed the straw line with bales and can be equipped with the LINKA string removal system, which automatically removes the strings that bind the bale together.

This makes the system a fully automated industrial straw handling solution, seamlessly delivering straw for the next stage of the process.

The shredding system effortlessly handles fuel with up to 25% moisture and easily processes both big bales (Heston) and midi-big bales (Krone).

The TWIN shredder features a low-speed drum system, which significantly reduces the risk of spark formation caused by foreign objects in the fuel and minimizes system wear.

Fuel is pulled upward, where it is shredded into smaller pieces before falling into the transverse auger.

The transverse auger then transports the shredded fuel to the inclined auger, which moves the fuel into the stoker and further into the boiler.

The TWIN shredder is controlled based on the boiler’s heat demand. If fuel production is too low, the drum speed increases.

The forward movement on the conveyor belt is accelerated, and the pressure on the shredder rollers is adjusted based on amp readings until the desired oxygen level percentage is reached. Similarly, the speed is reduced if the oxygen level is too low.

The shredding system can be equipped with conveyor belts of a desired length and can be combined into a fully automated straw handling system. This includes a crane system that adjusts the delivery of straw bales to match the capacity the shredder is set to deliver, as well as a LINKA string removal system for efficient removal of bale strings.

• The straw bales are placed on the straw conveyor and transported to the shredder. Here, the shredding drums will tear the straw bale into smaller pieces, which fall into the transverse auger.
• The transverse auger transports the shredded straw to the inclined auger, which leads the straw into the stoker and further into the boiler.
• A safety switch is installed on the rear doors of the shredder, stopping the shredder when the door is opened.
• The shredder is constructed from steel grade 37, which is surface-treated afterward. The shredding drum is equipped with blades. The shredder is fitted with three shredding drums.
• The shredder is equipped with an automatic fire extinguishing system that, in case of fire, sprays water over the shredder. Sensors are installed and fully activate at 94°C, opening the water supply to the nozzles.
