How to choose small wood pellet machine?

Small wood pellet machine is used to make pellets from agriculture and forestry wastes, such as straw, sawdust, rice husk and bark. Through pre-treatment and pelletizing, these bulky materials become high-density pellet fuel.

With the increasing demand of biomass fuel, small pellet machine has broad market prospect. To engage in biomass business and make profit, you need choose a good pellet machine supplier. In this passage, I’ll introduce the factors you should consider when choosing small pellet machines.

High quality small pellet machine have to meet the following standards.

High quality small wood pellet machine can be applied to various kinds of materials, whether they are individual or mixed together. The density of wood pellets should be 1.1-1.3g/m3. To make 1 ton of wood pellets, the power consumption should be between 35℃ and 80 ℃.

The roller and flat die are wear parts of small pellet machine. Their hardness determines the working life of pellet machine. You’d better choose those made of superior alloy steel, whose hardness should be no less than 50 HRC.

High quality small pellet machine allows you to feed dry materials to it and get dry pellets, which we call “dry in and dry out”. You don’t need to add any binders because the molten lignin can help form the pellets.

To ensure efficiency, the drive system should be bevel gear drive rather than belt drive or worm gear drive. It has higher efficiency and longer working life, and avoids the slippery of belt.

To ensure safety, the power system should conform to the CE standard. It is better to have an emergency button on electric control cabinet, so that operators can shut it down when something is wrong.

It is inevitable that you will encounter some problems and fault when using small pellet machine. So you need to take after-sale service into account. The warranty period should be at least 1 year. Suppliers are supposed to provide life-long after sale service and free reparation.

How can you choose a suitable small pellet machine?

You should be clear of your daily pellets production, and choose the pellet machine with suitable capacity. Take Gemco for example. The production capacity of our small pellet machine is from 50kg/h to 400kg/h. They are classified into multiple types.

Type	Model	Power	Capacity (kg/h)	Weight (nw/gw)	Packing size (mm)
Electric motor	ZLSP-D 150B	5.5kW	50-100	95/110	800x450x700
	ZLSP-D 200B	7.5 kW	80-120	200/230	1050x480x930
	ZLSP-D 230B	11 kW	120-200	290/320	1180x540x1000
	ZLSP-D 260B	15 kW	160-250	320/360	1240x540x950
	ZLSP-D 300B	22 kW	250-400	350/380	1300x560x1100
Diesel engine	ZLSP-D 150A	8HP	50-100	180/220	100x500x750
	ZLSP-D 200A	15 HP	80-120	210/240	1460x750x900
	ZLSP-D 230A	22 HP	120-200	280/310	1560x850x1100
	ZLSP-D 260A	30 HP	160-250	330/360	1200x500x1070
	ZLSP-D 300A	41 HP	250-400	410-450	1220x600x1000

After confirming your requirement, you need inspect the quality of pellet machine. The durability is more important than appearance. So pay more attention to the materials. The thicker the shell, the better.

I recommend you to take some of your materials to test the machine, and inspect the practical pelletizing effects. High quality pellets has smooth surface, high hardness and slight elecampane.

Common mistakes in choosing wood pellet machine

Mistake 1: Low power and high production

Some customers want to find a pellet machine with high capacity but low power consumption. But a pellet machine can’t achieve large production without high power. So don't be misled by the brag of sellers. You’d better inspect the manufacturers and test the machine in person.

Mistake 2: Price come first

As the saying goes, you get what you pay for. Reasonable price is the guarantee of reliable quality, after-sale service and superior materials. Low price can win customers for a while, but only high quality can maintain customers for long. You will benefit a lot from a wise investment.
