60 TPH Pellet Plantwith three 20 tph (nominal) pellet lines

Each plant consists of 20 TPH rated lines.

Each line is in effect a plant module.

For plants larger than 20 TPH, additional lines are For instance, a 60 TPH plant consists of [3] 20 TPH

For plants larger than 20 TPH, additional lines are For instance, a 60 TPH plant consists of [3] 20 TPH

The modular design with replicated parallel lines results in there being veryfew points in the process where any equipment failure can shut the entireplant down. In most other plants, a dryer outage would mean a totalplant shutdown. In a 60 TPH Astec plant, a dryer outage means the plantcontinues to operate at 40 TPH. In fact, there are very few reasons why theplant would ever be completely shut down. Even major maintenance cyclesmay be performed line-by-line while the plant continues to operate on theother lines. Redundant design reduces down time.

PROVEN COMPONENTS

The Astec pellet plants components, almost all of whichare built by Astec in our manufacturing facilities locatedin Chattanooga and other U.S. cities, consist largely oftried and true equipment that has been in productiveservice and perfected for decades under extremeconditions of service worldwide.

These proven fabrication designs have been upgradedwith the latest t echnology to provi de the best possiblewood pellet plant equipment in the world today.

Using proven equipment, with many possibleapplications, provides Astec wood pellet plant owners,investors, and lenders with a high level of productinvestment security.

Major components include: live bottom cold feed bins,a pre-dryer, 40M BTU convectec heater, 60M BTU burner,bio-mass tube dryer, waste screw, 4,000 gallon hot oilexpansion tank, wood fuel skid, screw conveyors, distributorscrews, wood fines conveying fans, pellet conveying fans,50,000 ACFM scavenge baghouse, long term conditioner,pellet cooler, pellet collecting conveyor, dust blower, bucketelevator, 5,000 cubic feet loadout silos.

QUICK START-UP

The Astec suspension wood dust burners allow quickplant startups and shutdowns. Unlike traditional burnersystems that typically take all day or more to get up tospeed, Astec plant startups can go from dead cold toproducing pellets within as little as two to three hours.

The Astec burner system is a multi-fuel burner that may befueled by wood dust simultaneously with natural gas, oil,or liquified petroleum gas (LPG).


5/7

ASTEC pellet plants are relativ elyquick and easy to set up andstart up due to ASTECs modulardesign concept. Most major plantcomponents are preassembled inour shops and shipped to your siteready to lift from the truck and setdirectly into operating position onan asphalt or concrete pad.

INNOVATIVE MODULAR DESIGN

SUPERIOR DRYING AND EMISSIONS

The Astec pellet plants superior drying and emissionscontrols technologies enhance safety, performanceand produce less emissions.

We do not use traditional air-swept rotary dryers w ithinherent direct hot gas exposure to highly flammable

wood dust and chips. All of the off-gases from thedrying process are conveyed to the combustionchamber of the hot oil heater where any volatileorganic compounds (VOCs) and fugitive wood dustare consumed, not released. This means that even verybig Astec pellet plants may be operated without RTOs.

SUPERIOR SAFETY

We use rotary hot oil tube dryers. Drying by thismethod keeps the drying chips in an almost oxygen-free environment. Very little oxygen means very littlechance of fire or explosion.
