1. Introduction
1.1 The Introduction of Biomass Pellet
Biomass pellet is a kind of clean fuel which is made of various agro-waste and forestry residue such as stalks, sawdust, etc. Biomass pellet is an ideal substitute for traditional energy like coal, diesel and natural gas. The main processing procedure includes crushing, drying, mixing with additives and pressing.

1.2 Technical Parameter and Advantages of Bio-pellets
(1) Price advantage
Bio pellets have a price advantage over petro products. Here is a chart of the comparison of fuel cost of them.
Fuel Cost Ratio—- Biomass pellet: Heavy oil: Natural gas: Diesel=1:1.26:1.45:1.84
(2) Policy advantage
The development of biomass pellet fuel complies with requirement of energy policy.
(3)Technical advantage
Our company has technical expertise in biomass pellet mill equipment.
a. Sawdust rotary drum dryer, featured with large capacity, low energy consumption and low investment.
b. Wood pellet mill: various models; Driven by gear, so that the output is improved by about 20% when compared with that of belt drive.
c. Automatic biopellet packing machine: adopts highly intelligent control system,with stable performance and high precision.

1.3  Pellet Plant Project Size
The proper project size is to produce an annual output of 40,000 tons of biomass pellets. This biomass pellet production plant is composed with 4 production lines and each line has an annual production of 10,000 tons. The production time is 20 hours per day and 11 months per year; and the capacity is 120t/day.

1.4 The pellet mill equipment and workshop area
Each production line is equipped with a set of biomass pellet mill and other auxiliary equipment; the workshop area is about 3,000m2.

2. Processing Procedure
The whole biomass pellets processing includes crushing, grinding, draying, mixing, material transporting, extrusion forming, cooling, quality testing, packaging, warehousing of acceptable finished products and selling. Here is the schematic layout of a typical biomass pelleting plant.

The bio pellets production flow is as following:

4. Factory Layout
The factory area is about 5,000 m2 including the floor space of workshop area and other supporting building. The workshop area is about 3,000 m2.

5. Staffing
There should be 30 workers, 6 management person, 2 salesperson in the plant for the production and selling of biomass pellets.
The biomass pellets plant is running on two-shift or three-shift.

6. Investment Amount
The total investment amount is about USD0.73million, including the rent of factory, training cost and after-sale cost.
