RICHI Machinery Factory possesses superior intelligent and automated technologies, and thus our biomass pellets making machine productivity and product quality are at the forefront of the industry.
Introduction of Biomass Pellets Making Machine
Specifically developed for the utilization of renewable resources
A biomass pellets making machine is a mechanical device that uses physical compression to transform various agricultural and forestry waste materials which are originally loose, irregular, and difficult to store and transport into high-density, uniformly shaped solid fuel pellets. Therefore, it realizes clean energy production and enables the efficient recycling of resources.
Nearly all plant-based waste materials can serve as raw materials for biomass pellets making machines, including forestry residues such as wood chips, sawdust, branches, and bark, as well as agricultural residues like corn stalks, wheat straw, rice husks, cotton stalks, and sugarcane bagasse. These raw materials all require crushing and must be processed with the appropriate moisture content.
The biomass pellets produced are primarily used as a clean fuel to replace coal in industrial boilers, power stations, home fireplaces, and similar applications. They offer high combustion efficiency and burn cleaner than the raw materials themselves. Biomass pellets can also serve as feed for ruminants, which makes them easier for livestock to consume and reduces waste. Biomass pellets transform waste into clean energy or feed, offering both environmental and economic benefits.
How Does a Biomass Pellets Making Machine Work?
Biomass pellets making machine is a key type of biomass energy equipment. This machinery processes plant-based waste into uniform solid fuel pellets with high density and burning efficiency through mechanical compression molding. Let’s explore the primary working principle of RICHI Machinery’s MZLH series biomass pellets making machine.
Firstly, the raw materials for making biomass pellet fuel are put into the barrel of the feeder, because it is rotating, so it is easy to fling the raw materials to the inner wall under the action of centrifugal force, so as to form a uniform ring-shaped layer of materials.
And then, after the ring die and the pressure roller’s intense extrusion, the raw materials will be extruded out of the die holes with a cylindrical shape and the raw material will be extruded from the hole of the die in cylindrical shape and cut in to uniform pellets by the cutting device, that is, biomass pellets.

RICHI MACHINERY
Components of the Biomass Pellets Making Machine
We design each unit with high quality materials, such as stainless steel construction, Siemens motors, and SKF bearings, which ensures the biomass pellets making machine’s high efficiency, stability, and excellent results.
Feeder
Driven by a variable-frequency motor, it enables precise control of feed rates by adjusting rotational speed, which ensures stable production. It is responsible for uniformly, continuously feeding raw materials into the next stage.
Ring Die and Press Rollers
The material is compressed by the press rollers within the ring die and forced through the die holes to form cylindrical pellets. The press rollers operate in conjunction with the ring die. They do not rotate actively, but press the material into the die holes through the combined action of the material’s friction and the hydraulic system.
Drive system
The drive system provides power to the entire biomass pellets making machine. The main motor increases torque via a reduction gearbox, which drives the spindle to rotate at high speed. The spindle drives the ring die to rotate.
Siemens motors
Siemens motors are renowned for their high efficiency and stable performance, which ensures the biomass pellet machinery maintains consistent production efficiency for a long period.

Why Produce Biomass Pellets?
The production of biomass pellets is a process of transforming waste into valuable resources and upgrading energy sources in essence.
Clean Combustion
RICHI biomass pellet machinery employs high-efficiency combustion technology, and the emission of pollutants such as sulphur dioxide is significantly lower than that of coal, which is a relatively clean fuel. Processing agricultural and forestry waste into pellets can reduce smog and air pollution.
Reduce Energy Costs
For factories, farms, schools and other locations where heat or steam is required, using biomass pellets as an alternative to natural gas, diesel or electricity can significantly reduce energy costs.
Convenient For Storage and Transportation
Loose wood shavings, straw and other biomass materials possess low bulk density and substantial volume, so it results in prohibitively high transportation and storage costs. When compressed into pellets, their energy density increases significantly, which makes them easier for long-distance transport and large-scale storage.
Significant Economic Benefits
The raw material costs for biomass pellets are low, and their operational expenses as a fuel typically are much lower than those of oil, electricity, and natural gas. They are comparable to or even lower than coal, which provides users with an exceptionally cost-effective energy option.

How to Select a Suitable Biomass Pellets Making Machine?
1.Clarify Core Requirements
The selection of biomass pellet raw materials is crucial. Woody raw materials, particularly hardwoods, present greater compaction challenges and demand higher-quality machinery. Among agricultural straws, corn stalks and wheat straws possess distinct fibre structures, which are usually more difficult to form than wood chips, so they require greater pressure and suitable dies. Subsequently, based on your raw material supply and market demand, you should select a production capacity slightly exceeding current requirements to allow scope for future expansion. If you require to build a 1T/H biomass pellet plant, we recommend selecting either an MZLH420 or MZLH520 biomass pellets making machine.
2.Determining Biomass Pellets Maker Type
Biomass pellets making machines are typically categorized into two types: ring die pellet makers and flat die pellet makers. These two types exhibit numerous differences in design, operating principles, and production capacity. The biggest distinction is that the production capacity of ring die pellet makers far exceeds that of flat die pellet makers. Due to their high output and low energy consumption, many customers opt to purchase ring die biomass pellets makers for producing biomass pellets.
3.Examination of Core Components
The core lifespan and performance of a biomass pellets making machine depends on its key components.
Ring dies must be manufactured from high-quality alloy steel to ensure exceptional wear resistance. RICHI not only holds a practical novelty patent certificate for ring die pellet machines, but the materials and manufacturing processes for these dies have undergone extensive testing and experimentation. Motors are selected from national standards or renowned brands and have sufficient power. RICHI biomass pellets making machines all use Siemens motors, which ensures that the biomass fuel pellet machine maintains stable production efficiency for a long time.
