Applications of Sawdust Briquette Press

Wood sawdust is a kind of common seen biomass. The furniture factory, woodworking factories and the like are main sawdust producers. The sawdust generated by these manufacturers usually irregular shape and size, and even contains small wood brick. But no matter what kind or shape it is, the main composition of sawdust is carbohydrate. The heat produced by burning 1kg sawdust equals to 5kwh electricity. Therefore, sawdust is a good source of fuel.

sawdust can be made into pellets or briquettes

Wood sawdust is a renewable natural material that can be made into solid biomass fuel like briquette or pellet. There is a kind of sawdust briquette press that can produce both sawdust briquettes and pellets. The briquette press machine can process loose sawdust into thick cylinder briquettes or thick stick shape pellets without adding any additive. The pellets can be used in home heating stove or industrial boiler, while briquettes are mainly used in industrial boiler.
 

Significance of sawdust briquette press:

1.The sawdust briquette press machine can be called GREEN energy equipment, since it contributes to environmental protection.
It makes full use of the waste sawdust, wood blocks and chips. The burning of briquettes does not pollute the environment. If fully combusted, it only releases CO2 rather than other harmful gases. Now in many countries, especially European countries, sawdust briquette presses are widely used.
2.From energy safety perspective, the sawdust briquette press can deal with the shortage of energy resources and even decreases the fuel cost.
For industries like power generation, central heating or metal smelting, the fuel plays an important role. Most factories use coal to create heat, but its price is increasing and it also harms the atmosphere. Besides, coal is a non-renewable energy source. However, sawdust briquette (or other briquettes) is a good replacement to coal since it cost much less but can produce almost the same amount of heat with the same quantity! And sawdust briquette is renewable!
Now the world pays much attention to environmental protection and sustainable development. But facing the large quantity of biomass waste produced every day, people are still distressed by how to deal with it.
 

Sawdust briquette press application

The sawdust briquette press can make the biomass with lower than 30% moisture content into briquettes without any binder. The raw material can also be crop stalk, bagasse, grass, straw, and so on. Under proper pressure, temperature and moisture, the biomass is extruded into briquettes with 8-70mm diameter and 3500-5500kcal/kg.

By the processing of sawdust briquette press machine, the briquettes have high density, high heat value, can be easily and conveniently used, stored or transported. The clean sawdust briquettes can replace fire wood, coal, natural gas, liquefied gas, etc. to be used in stove, boiler, drying stove, and so on for both industrial and home use.

Sawdust briquette machine is a screw-type extrusion press for making briquettes as fuel from biomass materials. It is one of the main machines in making bio-charcoal briquettes. It is also called a biomass briquette press or wood charcoal machine.

Advantages of sawdust briquettes

1. Wood sawdust briquettes can be used as fuel for burning directly. Compared with natural wood, it has a higher density and heating value.
2. The sawdust briquette machine can use residual wood and agro-waste to produce briquettes, and these wood briquettes can be carbonized into charcoal. It changes the traditional way of making charcoal from lump wood, helping reduce tree felling.
3. Compared with natural timber charcoal, sawdust briquette charcoal has a higher heating value and longer burning time.

Biomass Materials for making briquettes

Biomass materials for producing briquettes can be wood sawdust, rice husk, tree branches, coconut shell, coffee grounds, bagasse, peanut shell, bamboo, etc. One thing in common among these materials is that they all contain a certain amount of lignin. Lignin is an important ingredient for briquette forming, it can reform the shape in the condition of high pressure and high temperature.

Required size and humidity of sawdust for making briquettes

The size and moisture of materials are important for making high-quality wood briquettes. Regarding the size of the material, it needs to be less than 5mm, and the moisture content should be less than 12%. To make the materials meet these requirements, you can choose a wood crusher and sawdust dryer to process the raw materials.

How to make sawdust briquettes

First, set the temperature of the sawdust briquette machine to 280℃. After the temperature rises to 280℃, begin to feed materials into the sawdust briquette machine. Sawdust is pushed by the rotating screw forward to the end of the mold. Under high temperatures and high pressure, sawdust is forming into briquettes and is expelled from the mold. The briquette producer needs to adjust the temperature according to the quality of the briquettes until to get the ideal wood briquettes.

The shape and size of sawdust briquettes

The shape and size of briquettes are determined by the mold barrel. Diameter of briquettes is 50mm. All of the briquettes made by the sawdust briquette machine are hollow. 

Consumable parts of sawdust briquette machine

Spiral propeller

Driven by the pulley, the spiral propelling shaft continuously transports the material to the front outlet, and gradually increases the pressure on the material to extrude the material into shaped briquettes. Therefore, the front section of the propeller has the greatest friction with the material and is also the most susceptible to wear. Our screw propeller shaft is made of Cr40 steel, which has a good balance between the toughness and wear resistance of the propeller shaft. The front section of the spiral is overlayed with tungsten carbide electrodes to further increase wear resistance.

Heating elements

As mentioned earlier, sawdust is rich in lignin. Lignin is sticky under high-temperature conditions and helps to shape the sawdust. The heating temperature setting varies according to the material. If the raw material is wood sawdust, the temperature is generally set to 280° first and then adjusted to the optimal temperature according to the quality of the sawdust briquettes.

Molding sleeve

Molding sleeves are available in two shapes, square and hexagonal. The most popular size now is 4.8-5cm in diameter. Because after a large number of tests and production practices, it has been proved that the sawdust briquettes produced by 4.8-5cm molding sleeves have the best quality.
