Today, there are many types of wood pellet machine. According to the scale of application, wood pellet manufacturers usually use inverter-type ring die wood pellet mill press machine, and small granulators are used by families or farms. We usually call this granulator for flat die wood pellet machine, household wood pellet granulators,home use wood pellet machine, etc.The homemade pellet mill is a small flat die pellet machine used by small scale pellet producers such as household and farms ,etc to process biomass materials such straws, grass, peanuts, shells, wood wastes, such as branches, sawdust, shavings, and any other combustible materials available into energy pellets for the heating, cooking and other purposes. It must be properly selected to meet the requirements of the household. The following factors should be determined before selecting the mill: types of formulation, ingredients used, capacity requirement, horse power, pellet quality requirements—durability, product mix—both required pellet diameter and length.These factors are interdependent, so integrate consideration is necessary to buy a homemade pellet mill.
1.Pellet machine classification
Even though there are various designs of pellet mills in the markets, there are two types of pellet mills in terms of pellet formulation: the ring die pellet mills and flat die pellet mills. The ring die pellets mill is featured by large scale pellet production which is generally adopted by commercial pellet manufacturing. While the flat die pellet mill is featured by small space occupation, light weight, simple design and easy operation, which is usually the choice of small scale pellet producers and consumers. Because the homemade pellet producers are usually small scale pellet consumers so the flat die pellet mills are preferred by home users and therefore it is also called as homemade pellet mills.
The capacity defines the choice of homemade pellet mills. In the market, various pellet mills with the capacity ranging from 30-50kg/h to 2000-3000 kg/h are at choices. In front the various choices, how can you choose the capacity of your pellet mill? You can estimate the consumption volume of your pellets or you can calculate the energy you use daily and then you can get the capactiy requirment of your pellet mill. In the following forms are the comparison of heat values of different fuels for your reference to calculate and get the capacity you need for you home and also you can use the Heating Fuel Compariosn Calculator to compare residential heating fuel prices and costs to get the most cost-effective solution for your home.

3.Feedstock and Pellet durability
The feedstock and the quality of the pellet mills decides the production of pellets and the durability of the pellets. The durability of the pellet is closely related with the retention time of the raw materials which is influenced by the thickness of the die and drilling pattern of the die holes. Therefore, before starting to make your own pellets, it is necessary and import to know the properties of your feedstock and consult the pellet mill manufacturer about the die characteristics such as diameter and effective thickness, total thickness, counter-bore depth, inlet diameter and inlet angle.
The power required to form a pellet is determined by both the ingredients in the formula and the pellet quality needed. Higher pellet quality requires higher power input. And there are four different flat die pellet mills driving by different engines such as diesel engine, gasoline engine, electric motor, and PTO at your choice which can be chosen according to your power conditions and capacity requirements. After considering your own energy situation such as the availability of diesel oil and the supplying of electricity , you can decide which one you want to purchase.
