How to build a 3-3.5 t/h straw pelleting plant?

1. Raw materials

This is the first thing you need to consider. You have to know what your raw material is, whether it is in sufficient supply, and whether it can be made into pellets after testing.

For example, there are many fields around, and various straws, straws, and rice husks can be used; if the supply of straws is insufficient, other raw materials can be investigated and supplemented.

biomass straw materials and pellets

For example, is there a sawmill, furniture factory nearby? Sawdust and waste wood can be used to make pellets; there are many mountains around. According to the characteristics of the region, branches, bamboo, palm shells, etc. can be used as raw materials. After solving this step, you will have a good start.

2. Site selection for 3-3.5 t/h straw pelleting plant construction

There are many things you need to consider in this regard:

  • Area: The land area of the factory area should meet the requirements of production technology and transportation, and reserve land for expansion.
  • Water source: An environment with convenient water supply can ensure the efficiency of production.
  • Electricity: The small electric power can’t drive the machines with relatively large power consumption such as biomass pellet mill, pulverizer, straw dryer, pellet cooler, etc., so a transformer is needed to ensure the power supply.
  • Transportation: The factory site should be selected in a place with convenient transportation and abundant raw materials, which can not only facilitate production and transportation, but also reduce costs and facilitate transportation and sales.

3. Plant layout

First you need to determine your 3-3.5 t/h straw pelleting plant process. In addition, all kinds of equipment in the production line should be arranged reasonably and compactly according to the structure of the factory building, which is not only convenient for operation, maintenance and management, but also saves area.

The main straw pellet production equipment, such as pulverizers and straw pellet mills, should be placed as close to the window as possible to facilitate lighting and operation.

Why use straw to process biomass pellet energy?

Biomass energy is an important part of energy resources. Its development and utilization can alleviate my country’s energy shortage, provide clean and high-quality energy, and can partially replace coal, oil and natural gas. As biomass energy, it has the advantages of no public harm, renewable and beneficial to environmental protection.

Many countries are very rich in biomass energy. The development of biomass solid fuels and the implementation of coal substitution can significantly reduce carbon dioxide and sulfur dioxide emissions and produce huge environmental benefits.

Especially in recent years, the government and the public have paid more and more attention to the impact of agricultural residues residues on environmental pollution, and put forward higher requirements for the resource utilization and harmless treatment of agricultural residues. 

Therefore, investing in the establishment of a straw pelleting plant will be supported by the government.

Hazards of incineration of straw and other agricultural, rural and agricultural residues:

  • Pollution of the air environment, endangering human health. When burning straw, the three pollution indexes of sulfur dioxide, nitrogen dioxide, and inhalable particulate matter in the atmosphere reached their peaks, among which the concentration of sulfur dioxide was twice as high as usual, and the concentration of nitrogen dioxide and inhalable particulate matter was three times higher than usual.

    Equivalent to the fifth level of daily average concentration. When the concentration of inhalable particles reaches a certain level, it will greatly irritate the mucous membranes of the eyes, nose and throat, and cause coughing, chest tightness, and tears in mild cases, and may cause bronchitis in severe cases.
crop straw
  • Cause a fire, threatening the safety of people’s life and property. Straw burning is very easy to ignite the surrounding combustibles, especially near the mountains and forests. Once a fire is triggered, the consequences will be disastrous.
  • Cause traffic accidents, affecting road traffic and aviation safety. Since there is a large amount of farmland on both sides of most expressways, the smog formed by burning straw will cause air visibility to decrease, and the visible range will be reduced, which will easily lead to traffic accidents.
  • Destroy the soil structure and cause the quality of farmland to decline. The burning of straw causes the ground temperature to rise sharply, which can directly burn and scald the beneficial microorganisms in the soil, affect the full absorption of soil nutrients by crops, directly affect the yield and quality of farmland crops, and affect agricultural income.
