A broad range of pellet stoves, central heating furnaces, and other heating appliances have been developed and marketed since the mid-1980s. In 1997 fully automatic wood pellet boilers with similar comfort level as oil and gas boilers became available in Austria.
With the surge in the price of fossil fuels since 2005, more and more families in Europe and many other places in the world, choose pellet stove for home heating. It is an environment-friendly method to keep warm and cook. Pellet stove uses less natural resources as its fuel is generated from waste or recycled materials, such as sawdust, corn stover, straw, rice husk, palm kernel shell and many other wastes into pellets. But, annual expenditure for the purchase of the wood pellet is not a small cost. How to save the cost of wood pellets? Many families choose to buy a small pellet mill. Can small pellet mill save money or not? Let me calculate together.
1. Price related items
First, we must figure out the cost of each of these two methods, purchase wood pellets and homemade wood pellets. In this article, not counting the human cost, equipment maintenance fees, maintenance fees, and the cost of replacement parts.
(1)The cost of purchase wood pellets: the quantity of wood pellets you need multiply by the unit price of wood pellets.
(2)The cost of homemade wood pellets yourself: the price of small pellet mill + electricity + cost of materials.
Queries through multiple channels, each project price are tentative as follows:
|
Small pellet mill (USD/SET)
|
Wood pellet(USD/KG)
|
Wood chip(USD/KG)
|
Electricity(USD/KW)

The model of the small pellet mill is AMSPLM120 and technical data as follows:

40-60(t/h)

2. Calculate
Assuming, the quantity of wood pellets of the family use in a period of time as X(kg). The capacity of the small pellet mill as 50kg/h. We draw the following functional relationship.
(1)The cost of purchase wood pellets=0.25X
(2)The cost of homemade wood pellets=890+0.1X+3×0.08×(X/50)
Based on the above two functions come under the graph.
3. Conclusion
Through calculated, when the quantity of wood pellets reached 6.138 tons, the homemade wood pellets costs and purchase costs equal. We call this point is the critical point. From the graph we draw the following conclusions:
(1)When the quantity of wood pellets you need is less than 6.138 tons, direct purchase more save money.
(2)When the quantity of wood pellets you need is equal to 6.138 tons, the same as the cost of buying and homemade.
(3)When the quantity of wood pellets you need is more than 6.138 tons, homemade wood pellets is more save money.
By function equation, when wood pellet market prices rise, cost of raw materials decline, or small pellet mill unit production increased, the amount of wood pellets reaches critical point will be reduced. That is, the wood pellet market price higher, the lower cost of raw materials, or the higher production of the small pellet mill, homemade wood pellets is very easy to achieve the effect of saving money.
4. Proposal
We can see from the above conclusion, the price of small pellet mill, the price of wood pellets, the price of raw material and other factors, which way more save money under what conditions.
You should choose according to your actual situation, if your need great amount, I suggest you buy a small pellet mill.
If you have own garden, farm or forest, I also suggest you buy a small pellet mill. Because, this electric flat die pellet mill is smaller in size, design and structure with capacity of Wood pellets 40-60 kg/h; Feed pellets 60-100 kg/h. Thanks to this salient features, it enjoys great popularity with small scale pellet biomass pellets and animal feed pellets production. You can use them to process a variety of agricultural and forest wastes, such as sawdust, corn stover, straw, rice husk, palm kernel shell and many other wastes into pellets.These material are free for you. Certainly, these must be sized to produce pellets. A lawn mower can handle some of this material, a chipper shredder can handle leaves and hay. Cleaning the material before putting it through the pellet mill may be needed to remove rocks lest you damage the die or roller. A winnow would be desirable if you are gathering leaves or grass in a rocky area.
If you can get the stove, pellet mill, shredder or hammer mill, and winnow for a fair price, and have the time to process a few tons of material, you can heat your home for the cost of running machinery. With the equipment, there is the opportunity to pelletize material for paying customers, or even rent the equipment if you dare.
If you can produce your own pellet fuel in sufficient quantity to supply all your own needs, there is a return on the investment in just a few years.
