1 Doppstadt AK series high-speed grinders are engineered for precision performance across a wide range of material applications. The upswing hammermill design results in a consistent, higher-quality product that is well-suited for retail-type products or for applications that require accurate specifications. With the ease of sizing screen changes, and reliability of the scraper-floor feed system, AK grinders add value by allowing customers to accept a wide range of source material, and efficiently produce a menu of different end products. As a result, the investment return on such a versatile machine can be easily determined, especially on the low-cost, high-productivity AK 235 entry model. AK 235 AK 435 AK 535 AK 635 / AK 635 SA A perfect entry-level model, the 239hp AK 235 delivers affordable performance for any material handling operation. In the next step of grinding, the AK 435 provides 430hp of high throughput of many applications For a high-volume, workhorse grinder, the AK 535 provides 530hp of dependable material processing. The 610hp AK 635 satisfies even the most-demanding expectations of multi-application facilities.

A Broad Range of Effective Applications Our exclusive combination of performance-enhancing features result in a tremendously flexible range of effective applications.

By maintaining a consistent material feed to the tramp-tolerant swing hammermill, product quality can be maintained to even the most-precise specifications.

2 A Broad Range of Effective Applications Our exclusive combination of performance-enhancing features result in a tremendously flexible range of effective applications. Unlike other grinders, Doppstadt AK Series grinders allow for precise control over the machine s various functions. By maintaining a consistent material feed to the tramp-tolerant swing hammermill, product quality can be maintained to even the most-precise specifications. From standard processing of dimensional lumber and green waste, to the conversion of wood waste into high-quality mulch, to the production of high volumes of high moisture food waste, to precise production of RDF and biofuels, AK grinders safely deliver reliable performance, low fuel costs and a very consistent final product specification. This dependability and efficiency allow customers to generate positive cashflow from their operations upon delivery of the machine. pallet wood and dimensional lumber Often contaminated, pallet and dimensional lumber is frequently processed to a strict specification for fuel. AK grinders provide extra redundancy against contaminants, while always delivering a consistent product size. This material can also be blended with organics, colored and sold as mulch which is more erosion resistant than pure organic mulches. compost and green waste Make a better finished product with accurate control over final product size by choosing from a range of easily replaceable one-piece screens. Screens can be quickly changed in less than 15 minutes. AK grinders are designed with an upswing rotor to create a long grinding path, ensuring a very consistent product size even throughout a long material run. mulch and regrind High-speed grinders can be employed in mulch production in the primary or secondary stage of processing. Because of the upswing hammermill design on the AK machines, material is reduced to a consistent and standard product which allows for precise production of different types and sizes of mulch with a single machine. 4

3 biofuel Organic material can be very valuable as a source of power for generation of electricity. High-quality biofuel will consist of a mix of different products with differing characteristics, and the AK grinders can blend and size each ingredient to balance the BTU value. Again, the consistency of the AK hammermill is crucial for maintaining standard product size. refuse-derived fuel Refuse is fast becoming another valuable fuel for powering electricity generation. Refuse-derived fuel (RDF) also has the same strict requirements for consistency and accuracy in blending, which AK grinders can effectively accommodate. Source material is also frequently contaminated requiring failure protection that AK grinders provide. high-moisture food waste Food waste recycling and composting is growing in all sectors of the market and there are few machines that can effectively process high-moisture content. The AK grinder is fully capable and can be an invaluable addition to any operation with this challenge. shingles Asphalt shingles can be reprocessed into particles that can be remixed to a certain percentage when creating new hot-mix asphalt. AK grinders are effective in creating recycling asphalt shingle (RAS) material by allowing for consistent control over product size, and delivering a highly fuel efficient process for maintaining profitability. drywall Recycling drywall can be a profitable source for generating gypsum, which is a valuable commodity in agriculture fertilization. AK grinders are able to generate gypsum powder from drywall at purity levels higher than that which can be mined, and are protected from the dusty environment by the fully enclosed engine compartment. stationary grinders Shredding tools used in this series are identical to those used in the mobile series, therefore keeping the need for spare parts to a minimum. 5

The free-swinging flail holders with easily replaceable tips are resistant against contaminants. The tips can be chosen according to the material. Baffle plate The material first meets a baffle plate with teeth at the start of the grinding path. The baffle plate is adjustable to allow for greater control at the front of the grinding path. Grinding basket The grain size can be determined by choosing among grinding baskets with mesh sizes between 1 and 16. With the quick-changing system it takes only 15 minutes to change the baskets. Remote control All the functions of the machine can be operated with the 16-channel remote control*, e. g. by the wheel loader operator. Rear conveyor The material is discharged by the rear conveyor. It is also possible to separate iron by means of a magnetic pulley* or an overband magnet*. Explanations and illustrations by the example of the AK 635 7
