Description
27S Electric Drop Feed Hog

Overview

The Peterson 27S Electric Drop Feed Hog is a wood waste processing machine, designed for applications that need a small footprint, excellent productivity, and easy maintenance.

Based on Peterson’s proven 2700-series rotor and grate design, the 27S Electric Drop Feed Hog is a simple and robust design that is ideal for sizing odd shaped materials.

The 27S Drop Feed Hog uses a 150 to 400 hp (112–300 kW) electrical motor that can be powered by a VFD or soft start controls. The 27S is a drop feed design, where material is gravity fed into the hopper, and is reduced against an anvil and sized through four grates which can be easily changed to match your product specification.

The 27S is available with either a pinned or drum rotor. The mill assembly is protected with a variety of shear pins, designed to break away under a heavy impact of trapped material, protecting your investment. The sides of the grinding chamber are made from thick, abrasion resistant steel, to protect the rotor, and facilitate a long wear life.

The 27S Electric Drop Feed Hog is easily serviced by large access doors on the front and rear the machine, allowing easy bit and grate service, minimizing maintenance and machine inspection time.

4800F Chain Flail Debarker

Overview

Continuing Peterson’s long history of innovation, the 4800F Chain Flail Debarker is the 6th generation design and has all the features that clean chip operations demand.

The Peterson 4800F Chain Flail Debarker multiple log delimber/debarker is designed to be used in tandem with whole tree chippers to produce high quality pulp chips. Capable of processing multiple logs from 2 to 23 inches (5–58 cm) in diameter, the 4800F increases productivity while reducing bark content, product handling time, and fiber loss.

Powered by a 350 HP (261 kW) CAT C9 Tier III or Tier IV engine, the 4800F meets all US, Canadian, and European Union emission regulations.  Equipped with a dedicated 135 gallon (511 l) hydraulic oil tank, and a 175 gallon (662 l) fuel tank to allow the 4800F to run an entire shift without fill-up.

The 4800F Chain Flail Debarker features upper and lower flails, direct drive lower in-feed and out-feed rolls, and a floating direct drive upper feed roll. The high capacity bark pusher has been redesigned and is now 5 feet (1.5 m) wide.

With a retractable gooseneck, the highway legal 4800F is easily moved between jobs. The four fixed landing gear (with floating pads) allow for adjustable operating height. The 4800F links wirelessly with the 5900E disc chipper for singular control of feed functions.

Since 1981, Peterson has specialized in the developing of delivery and processing equipment that turns low-grade organic materials into high value products.

W70 Windsifter

Overview

The W70 Windsifter is designed for cleaning light impurities, such as plastic, out of screened compost and biomass materials. The W70 Windsifter has a dedicated infeed hopper with an integrated metering roller, allowing operation independently of a trommel screen. The W70 can be loaded via a wheel loader, or used in tandem with a trommel or star screen for superior material separation.

The machine is fed using a wide, flat belt conveyor at the bottom of the hopper, into a chamber (via a metering bar) where a strong air stream aerates the material. Light material (such as plastic) is pulled out of the material stream, and sorted material is then dropped onto two discharge conveyors. The first conveyor has a stone separator to remove light weight stones from the material and the final discharge conveyor has a magnetic head pulley to remove any ferrous materials from the compost or biomass. The waste material is collected into a separate waste collection bin.

The W70 is powered by a fuel-efficient (108 hp) 81kW JCB diesel engine, and is easily moved with its built in pintle hitch system.  The highly efficient W70 system is  capable of throughput rates of up to 105 yd³ per hour.

Peterson is the “go-to” Master Distributor for Terra Select products in the US and Canada. Peterson is recognized as a leader in the quality manufacturing of horizontal grinders, chippers, flails, and blower trucks and trailers, and has been the Master Distributor for Terra Select products in the United States and Canada since 2012.

4710D Horizontal Grinder

Overview

The 4710D Horizontal Grinder is a track mounted horizontal grinder designed for high-volume producers with very demanding end-product specifications. Boasting 18 inches (46 cm) of ground clearance—this model is particularly suited for land clearing operations or other applications where mobility and frequent moving is desired. Track mounting also reduces material handling costs in conventional recycling yards as well.

The 4710D Horizontal Grinder is powered by a Tier IV Caterpillar C18 engine rated at 755 horsepower (563 kW). A Tier II (export only), 765 horsepower (570 kW) engine is also available. It features Peterson’s Adaptive Control System, which controls all components of the feed system to optimize output. This system senses variations in the engine load and adapts the operating parameters to produce the maximum amount of material at all times.

Peterson’s three-stage grinding process with an up-turning rotor and large grate area enables the 4710D Horizontal Grinder to produce materials to exact specifications. Quick-change multiple grate system makes it easy to customize grate configurations to produce a wide variety of finished materials. Grates are removed through an access door on the side wall.

The IQAN control system provides the operator with complete engine and system parameters to simplify set up to efficiently operate the unit.
