Biomass Pellet Factory In Brazil

RICHI MACHINERY

overview

This is a biomass pellet factory in Brazil project. The client is a biomass energy company from Brazil. In April 2024, it invested 390,000 US dollars to build a high-purity biomass fuel pellet project with an annual output of 30,000 tons using the existing site of 3,868m2.

The project mainly produces biomass fuel pellets. The equipment purchased by the client includes 4 sets of biomass pellet mill equipment, 1 set of weighing scales, 1 slicer, 2 crushers, 2 biomass dryers, etc.

In order to ensure the high combustion value and non-coking characteristics of the project products and satisfy users, this project strictly controls the source of raw materials and ensures the quality of raw materials.

The biomass pellet factory in Brazil project only recycles waste wood generated by the rough processing of wood in various wood yards and furniture factories, waste wood damaged by various packaging companies and transportation companies, branches cleared from greening and trees (leaves have been cleared), and straw dried at the project site. Raw materials containing impurities such as spray paint, glue, metal, and cement are not recycled.

The annual electricity consumption of the project is 300,000 kWh, mainly for mechanical equipment and lighting, which is supplied by the local Power Supply Station to meet the power demand of the project.

The biomass pellet plant in Brazil project has a labor quota of 9 people, none of whom are accommodated in the factory area. The project production time adopts a one-shift work system, each shift works 8 hours, and the annual working time is 300 days.

	Drainage	Rainwater and sewage are separated; domestic sewage is treated in septic tanks (volume 10m3) and used to fertilize surrounding farmland, not discharged
	Power supply	Local power supply network
Environmental protection engineering	Waste gas treatment	Raw material loading and unloading dust: set up a fully enclosed warehouse, install hard doors at the warehouse entrance and exit, and close the door when there are no vehicles entering or leaving.
		Dust from the project’s feeding, crushing, screening, pulverizing, drying, granulating, and conveying processes: The belt conveyor is fully enclosed, the crusher is enclosed on three sides, and the crusher, crusher, dryer, and granulator are equipped with gas collection hoods at the feeding and unloading ports. The dust is collected by the gas collection hoods, treated by the membrane bag dust collector, and then discharged through a 15m high exhaust pipe.
		Hot blast furnace exhaust gas: Install a low-nitrogen combustion device + 15m high exhaust pipe for discharge.
	Wastewater treatment	Domestic sewage is treated in septic tanks (volume 10m3) and used to fertilize surrounding farmland without being discharged
	Noise control	Foundation vibration reduction, factory sound insulation, wall sound insulation
	Solid waste treatment	①Domestic waste: After being collected in garbage bins, it is regularly transported to the garbage transfer station for treatment; ②General solid waste: Waste packaging materials are collected and temporarily stored, and then sold; dust is collected by dust collectors and then reused in production.

Process design of Brazilian biomass pellet production line project

Brief description of the process flow of this biomass pellet factory in Brazil project:

① Loading

Buy bundled waste wood, branches, and briquetted straw, which are transported into the factory by car and stored in the warehouse; during production, the waste wood, branches, and straw are poured into the crusher hopper by a forklift.

② Crushing

The crusher is used to crush waste wood, branches, and straw into small pieces.

③ Screening

A screen is provided under the crusher. Fine materials with a particle size of less than 5mm pass through the screen and enter the closed belt conveyor. Materials with a particle size of more than 5mm continue to be crushed.

④ Crushing

The screened fine materials are transported to the crusher through a closed belt conveyor and crushed into fine materials with a size of less than 30 mesh.

⑤ Drying

The crushed material is sent to the biomass dryer for drying via a closed belt conveyor. The drying method of this biomass pellet manufacturing plant project is direct drying. The hot air generated by the natural gas hot air furnace enters the drying drum to dry the material.

The drying temperature is 90℃ and the drying time is 10min, so that the moisture content of the material is reduced to below 10%.

⑥ Granulation

The dried material is conveyed to the hopper of the biomass granulator by a closed belt conveyor. The material enters the granulator granule chamber through the hopper and is pressed by a mold to obtain biomass pellets that meet the length and density requirements.

⑦ Cooling

The granulated material is conveyed to the finished product silo by a closed belt conveyor for natural cooling to room temperature.

⑧ Packaging

The cooled material is conveyed to the packaging machine by a closed belt conveyor for packaging. The packaging specifications are 25kg/bag or 1 ton/bag and are stored for sale.
