Gas vs pellets from biomass pellet mill

1.Gas vs pellets from biomass pellet mill

What is the difference between natural gas and rice husk pellets from the biomass pellet mill? We can comprehensively analyze and compare the differences between the two from many aspects.

（1）First of all, the combustion value of natural gas is 9000 calories, and the combustion value of rice husk pellet made by biomass pellet mill is 4200 calories. Natural gas is 3.6 yuan per cubic meter, and the combustion cost of one ton of pellets is about 900-1200 yuan.

Assuming that a ton boiler burns 600,000 calories in one hour, the natural gas and pellets that need to be burned are 66 cubic meters and 140 kilograms, respectively. Let’s calculate according to the previous: take China as example: the cost of natural gas is 237.6 yuan, and the cost of pellets made by biomass pellet mill machine is 126 yuan. Using natural gas costs twice as much as biomass pellets!

Rice husk pellets made by biomass pellet mill, as a new type of pellet fuel, not only have economic advantages but also have environmental protection benefits, and are more in line with the requirements of sustainable development. The shaped pellet fuel has a large specific gravity, a small volume, and is resistant to combustion, which is convenient for storage and transportation.

（2）Second, natural gas, like many fossil fuels, is a non-renewable resource. It’s gone when it’s used up. Biomass pellets are processed products of rice husks, straws and trees, crop straws and trees, and even bark palm pomace can be processed into pellets, which are renewable resources.

（3）Finally, the carbon dioxide released when biomass pellets made by biomass pellet mill are burned is equivalent to the carbon dioxide emissions released by plants during photosynthesis, which is almost negligible. Not to mention the pollution of the atmosphere. The combustion of natural gas has a great impact on the environment.

The above is the difference between natural gas and rice husk pellets from the biomass pellet mill.

2.Why the rice husk biomass pellet mill is not formed?

Summarize the reasons why the rice husk biomass pellet mill is not formed:

(1)The moisture content of raw materials.

To make straw pellets, the moisture content of the raw material is a very important indicator. The water content is generally required to be below 20%. Of course, this value is not absolute, and the requirements for different raw materials are different.

For our biomass pellet mill like pine, fir and eucalyptus, the moisture content is 13%~17%, and the rice husk moisture content is 10%-15%. For specific requirements, you can contact our staff for targeted answers.

(2)The raw material

Different raw materials such as straw and paper scraps have different properties, different fiber structures, and different degrees of difficulty in forming. Straw, rice husks, sawdust are all different.

(3)The ratio between the mixtures.

When pressing mixed pellets, the mixing ratio of various components also affects the molding rate.

Rice husk biomass pellet mill brings profit to customers. A few years ago, many regions have begun to pay great attention to biomass energy. Biomass energy is a clean and renewable energy source with high utilization rate and no air pollution. Species discarded by people are very popular now, because it is a kind of biomass energy material, which can be reused through rice husk biomass pellet mill, used for power generation and heating, and used for heating in winter, and has become the darling of heating.

Although the heat generated by crop stalks is lower than that of scattered coal, it is a clean substance with little pollution, and it is a treasure in the eyes of fuel sellers.

The emergence of the rice husk biomass pellet mill machine solves the problems of difficult rice husk processing and is suitable for the current development environment of our country.

3.How to control moisture in biomass pellet mill？

（1）The moisture requirements of the raw materials are relatively strict during the forming process of the rice husk biomass pellet mill. It is better to control the range value around 15%. If the moisture is too large or too small, the raw materials will not be formed, or even the molding will not be good.

（2）Compression ratio of abrasives of rice husk biomass pellet mill. The best solution for the abrasive compression ratio of the rice husk biomass pellet machine is to select the critical point for processing raw materials. But the control of this critical point requires personnel to tailor the mold compression ratio for you. Choosing different compression ratios of abrasives according to different raw materials is an important means to control the quality of biomass pellets.

4.Development of biomass pellet mill

What bottlenecks are encountered in the development of biomass fuel for biomass pellet mill?

（1）Traditional granulation technology with high granulation cost

（2）The understanding of biomass granules is not deep enough. Most people do not know enough about the high energy, environmental protection and easy-to-use characteristics of biomass granules. Even many energy-consuming units do not know that there are biomass granules products.

（3）The service supporting measures cannot keep up. After the biomass energy pellet products are produced, the transportation, storage, supply and other service measures cannot keep up, and it is inconvenient for users to use. The above problems will still be encountered during the development of biomass fuels, but we will continue to overcome them and welcome a better tomorrow for biomass fuels.

2. The application prospect of cheap wood pellet mill

Wood processing enterprises such as woodware factories, board processing factories, and door factories produce a large amount of shavings every day. Many bosses treat the shavings as waste, which wastes a lot of resources. In fact, the existence of this situation is ultimately due to a lack of deeper understanding of leftovers such as wood shavings.

The remaining products of wood processing such as shavings and sawdust are biomass materials. The so-called biomass energy is actually a form of energy in which plants convert solar energy into plants and store them through photosynthesis. Biomass energy is a special kind of energy that exists globally. The reserves are huge and there is huge development and utilization space.

Biomass energy is also a renewable and environmentally friendly new energy. Now the country is vigorously promoting the development and utilization of biomass energy. At present, the utilization of new energies such as hydropower, wind power, and solar power has begun to appear on a scale.

However, these new energies cannot fully meet the current energy demand. Oil, coal and other energies still play an important role in energy supply. Research data shows that the total reserves of fossil energy can only maintain human energy demand for less than 200 years, which is not a long-term solution.

Therefore, during the 14th Five-Year Energy Plan, the National Energy Administration specifically emphasized the need to increase the promotion of biomass energy.

So how to realize the energy value of biomass energy such as wood shavings? This is about the cheap wood pellet mill. The cheap wood pellet mill can compress biomass energy such as shavings into biomass energy pellets to replace the original fossil energy. After the coal ban, there is a huge energy gap.

Now many regions across the country have begun to vigorously promote biomass energy pellets to make up for the energy gap after the coal ban. In this environment, the sawdust pellet machine has a place where it shines.

How does poultry feed manufacturing machine affect pellets length?

Feed Machine

With the vigorous development of modern aquaculture and feed industry, the requirements for feed quality are getting higher and higher. For pellet feed produced by poultry feed manufacturing machine, pellet length is a very important quality evaluation index.

Neat and consistent pellet feed not only meets the sales needs of feed manufacturers, but also meets the actual breeding needs of users. Pellets that are too long, too short or uneven are not conducive to animal feeding. In actual production, the length of the pellets produced by the poultry feed manufacturing machine is generally required to be 2 to 3 times the diameter of the pellets.

For example, granules with a diameter of 3 mm are generally produced with a length of 6 to 9 mm. Of course, according to actual user needs and different feed varieties, the length requirements are not necessarily within this range.

Therefore, in order to produce feed pellets that meet the requirements or as close as possible to the requirements, we will discuss some factors that affect the pellet length of the poultry feed pellet making machine and find the corresponding control methods to make it beneficial to the production needs, which is important for feed manufacturers significance.

Based on years of experience in poultry feed granulator design and field debugging, we will discuss this issue from the following aspects.

1.Parameters affecting the poultry feed manufacturing machine itself:

The output of the poultry feed manufacturing machine is Q (kg/h), the inner diameter of the ring die is D (mm), the effective width of the ring die is W (mm), the linear speed of the ring die is V (m/s), and the rotational speed of the ring die is n (r /min), the ring die aperture is d (mm), the ring die opening rate is m, the number of openings is n (pieces), and the granulation length is L (mm),

For the above formula, it is not difficult to analyze the factors affecting the pellet length L of the poultry feed manufacturing machine:

(1) The influence of the output of the poultry feed manufacturing machine.

It can be seen from the formula that the pellet length L is proportional to the output Q. With other parameters constant, the higher the yield, the longer the pellet, otherwise the shorter the pellet. Therefore, adjusting the output of the poultry feed pelletizer to meet specific pellet length requirements is a possible option.

In actual feed production, feed manufacturers do the same, sometimes sacrificing large amounts of output to meet pellet length requirements. This issue will be mentioned in the following discussion.

(2) Influence of ring die line speed or rotational speed.

It can be seen from the formula that the pellet length L is inversely proportional to the ring die linear velocity V or the ring die linear velocity n. When the feeding speed, that is, the output Q, remains constant, the faster the ring die speed, the shorter the instantaneously extruded pellets, and vice versa. For different sizes of poultry feed pelletizers, the rotational speed of the ring die varies greatly.

Generally, the rotating speed of the small poultry feed making machine is high, and the rotating speed of the large poultry feed manufacturing machine is low, but the linear speed of the ring die is controlled within a suitable range, generally between 6m/s~9m/s, to meet the needs of granulation.

When the linear speed of the ring die is small, the quality of the pellets is high, but the pellets may be longer than required, and the line speed is too small, which will affect the output; when the linear speed of the ring die is high, although it is beneficial to improve the output, the pellets may be shorter than the requirements, and the quality of the pellets.

It will become worse, which requires the feed manufacturer to choose its own ring die line speed according to different feed varieties, and realize it by changing the transmission ratio of the poultry feed manufacturing machine transmission system.

(3) Influence of ring die aperture and porosity.

The ring die aperture D has no direct effect on the pellet length L, it has an effect on the length L together with the number of openings N, that is, the size of the ring die opening ratio, because the opening ratio and the square of the ring die diameter D and the number of openings N is proportional to the product of .

The larger the porosity of the ring die, the shorter the pellets, and vice versa, the longer the pellets. The aperture ratio of the ring die corresponds to different ring die apertures. For example, a ring die has an opening rate of about 25%, and a ring die has an opening rate of about 38%.

Generally speaking, the larger the pore size, the higher the open porosity. In actual production, especially when producing small-diameter pellets, such as 1.8mm shrimp, some users complain that the pellets are too long, which is caused by the relatively low opening rate of the ring die when the aperture is small.

One of the solutions is to sacrifice part of the yield, or to achieve by increasing the line speed of the ring die. In addition, adjusting the cutter is discussed below.

(4) Influence of ring die inner diameter, effective width and pellet density.

For the poultry feed manufacturing machine, the inner diameter D of the ring die and the effective width W of the ring die are fixed parameters, which generally do not change, and it is not easy for users to change them, so they will not be discussed here. The pellet density is related to the raw material for granulation and also to the compression ratio of the ring die.

The higher the compression ratio, the firmer and denser the pellets will be. However, for general products, the pellet density is not very different, so the pellet density is not the main influencing parameter, so it will not be discussed too much here. In short, for the same granulation raw material, the larger the pellet density, the shorter the pellet length.

2.How to solve the oil-free phenomenon in the production process of the poultry feed pellet making machine?

Poultry feed manufacturing machines are powered by electricity, but in many cases oil drive has become essential. As we all know, the equipment works fast and depends entirely on the power belt, and oil is particularly important as the power supply of the equipment.

Solve the problem of no oil in the poultry feed manufacturing machine:

(1) The manufacturer of the complete set of equipment with an output of 5 tons of concentrate recommends that you check the main shaft and rotor of the poultry feed pellet machine first to ensure that there is no material residue in the gap.

(2) The manufacturer of the small poultry feed manufacturing machine recommends that the user needs to carefully clean the filter screen in the oil filter.

(3) Remove the grease block of the poultry feed manufacturing machine. Usually, the tool of choice is: an effective hollow tube of a certain length, mainly used to clean the impurities stuffed into the oil hole.

(4) We often say that in addition to checking the above matters, we should also check whether there is oil leakage at the refueling part. If the oil leak is particularly serious, it will definitely lead to no oil supply. The solution to this problem is to add an oil liner.
