RICHI MACHINERY

Overview

Bamboo is a renewable resource with the advantages of light weight, durability and easy processing. In recent years, it has been widely used in building materials, home decoration, food packaging and other fields. However, the application of bamboo is not limited to this. With the improvement of people’s awareness of environmental protection, the application prospects of bamboo processing into pellets are becoming more and more broad.

The 5t/h bamboo pellet production line in Malaysia project covers an area of 4333m2 and the total investment in equipment is 310,000 US dollars. The project is mainly engaged in the production and sales of biomass pellets, with a designed annual production capacity of 30,000 tons of biomass pellets. The construction content mainly includes the installation of biomass pellet production equipment and supporting ancillary facilities.

The bamboo fuel pellet plant project has a labor quota of 6 people, and no board and lodging in the factory. The annual working days are 300 days, 2 shifts per day, and each shift works 10 hours.

Raw and auxiliary materials and energy consumption

This 5t/h bamboo pellet production line in Malaysia project mainly collects waste bamboo chips, sawdust, wood scraps, etc. generated by the local bamboo and wood industry for the manufacture of biomass pellets. The raw materials do not contain debris such as mud and sand, and no sorting is required.

Serial number	Name	Annual consumption	Maximum storage capacity	Source
1	Waste bamboo chips, sawdust, wood scraps	35000t/a	500t/a	Waste bamboo, sawdust (particle size less than 15mm), wood scraps generated by bamboo and wood industry in surrounding areas, with a moisture content of about 30%
2	Biological	300t/a	100t/a	The products produced by the project are used as fuel for the hot blast furnace of the project
3	Lubricating oil	0.05t/a	0.05t/a	Equipment repair and maintenance
4	Electricity	50,000KWh/a	/	/

• The raw materials of this Malaysia bamboo pellet plant project are prohibited from coming from home decoration and demolition waste, and must not contain toxic and harmful substances such as paint and glue.
• The construction scale of this biomass pellet production line project produces 30,000 tons of material particles per year. According to production experience, it is necessary to use about 35,000 tons of waste bamboo chips and sawdust per year. Due to various factors such as rain and the dryness and wetness of the raw materials, there is about 30% moisture, which will evaporate during the drying process, thereby reducing the moisture content of the product.

Design of 5T/H bamboo pellet production process

The main production process of this 5t/h bamboo pellet production line in Malaysia project is as follows:

The purchased raw materials are transported to the raw material warehouse in the factory by car. During production and processing, the raw materials are shoveled to the crushing workshop by a forklift, and the height is controlled at about 1.5m. Since the raw materials are mainly bamboo chips, wood chips, and wood scraps, the moisture content is high and the dust generation is small.

In order to ensure that there is no visible dust escape during the unloading and transfer of raw materials, the raw material unloading must be carried out in the raw material warehouse, and the material shall not be unloaded in the open air. It is strictly forbidden for the material to exceed the bucket box plate.

In windy weather, the raw materials shall be stopped from being shoveled to the crushing workshop or the bucket shall be covered with tarpaulin to prevent dust from escaping. At the same time, the transfer route and the dust on the ground in the workshop shall be cleaned regularly to keep the ground clean.

Since the purchased raw materials contain large-diameter raw materials such as scraps, they need to be crushed into smaller block materials by a crusher. First, the raw materials are poured into the hopper with a forklift, and the height is controlled at about 1.5m.

The crushed raw materials are conveyed to the hammer mill crusher through a closed conveyor belt for closed crushing. The crushed raw materials are screened by a screening machine to make the particle size less than 8mm. The raw materials that do not meet the requirements of granulation are returned for crushing, and those that meet the requirements enter the drying process.

The qualified raw materials after crushing are conveyed to the drying furnace through a closed conveyor belt for drying. The drying heat source is provided by the biomass hot air furnace. The hot air furnace of this project is a direct hot air furnace (the hot air of biomass directly contacts and heats the material).

The drying temperature is about 95~110℃ and the drying time is about 10min. The dried raw materials are conveyed to the semi-finished product silo through a closed conveyor belt for temporary storage and cooling at the same time. The fuel used for drying is self-produced molded biomass fuel bamboo pellets.

The raw materials after cooling in the semi-finished product silo are conveyed to the bamboo pellet machine through a closed conveyor belt and extruded into finished products.

The pelletizing process is a physical process, without adding any adhesives, no chemical reaction, and no heating is required during the granulation process. The molded biomass pellets are temporarily stored in the finished product warehouse through a belt conveyor.

The pressed bamboo pellets are bagged and ready for sale.

General layout

The 5t/h bamboo pellet production line in Malaysia project covers an area of 4333m2, mainly with two north-south workshops and office and living areas. The raw material stacking area is located in the north workshop of the project, and the main production area is located in the south workshop of the project. The production workshop on the south side is divided into crushing, pulverizing and screening area, drying area, granulation area, and product stacking area from east to west.

An exhaust pipe is set up in the production area, which is a certain distance from the project living area. The general layout of the bamboo biomass pellet plant project has clear functional areas. Under the premise of meeting production requirements and safety, it ensures smooth process flow, short material transportation, non-interference and mutual connection. The project layout is reasonable and feasible.
