Working Principle of Hay Pellet Machine For Sale
The working principle of the hay pellet machine for sale involves the physical process of compressing loose hay powder through mechanical pressure, friction-generated heat, and the material’s inherent physical changes. This process forces the material through a specific die, which converts it into high-density pellets. The entire process is divided into four distinct stages.
Compression
The crushed hay powder is fed between the ring die and the press rollers. As the main shaft drives the ring die to rotate at high speed, the immense centrifugal force and the material’s own friction cause the press rollers to rotate in the opposite direction. During this process, the material undergoes dramatically increased compression.
Conditioning
The combined effect of the continuous injection of steam and mechanical friction causes the temperature of the material to rise sharply over a short period of time. Then this heat softens the lignin in hay meal, which melts at high temperatures and acts as a natural binder.
Forming
Under immense pressure, the softened and initially bonded material is forcibly extruded through the die holes in the ring die. This high-pressure extrusion process involves generating high temperatures through friction. This causes natural binders like lignin to undergo complete plasticisation, which forms dense cylindrical strands.
Cutting
Fixed blades installed externally on the ring die cut the continuously extruded hay strips into pellets of a predetermined length. This convert infinitely long strip materials into standardised granular products of uniform dimensions for convenient packaging and use.
Why Make Hay Pellets?
Although the modern feed industry is highly developed, hay remains an indispensable component of livestock feed as the most fundamental roughage. Additionally, hay pellets can be used not only as feed but also as a biomass fuel for combustion, which is an environmentally friendly energy source. The processed pellets have two primary applications:
1.As high-quality animal feed
- During the pelleting process, vitamins, minerals, protein supplements, and other ingredients can be uniformly added to produce nutritionally balanced feed, which ensures balanced nutrient intake.
- During the high-temperature and high-pressure pelleting process, the starch in the raw materials undergoes gelatinization, thus enhancing the digestibility and absorption rate of the livestock.
- The pelletized form prevents livestock from selectively eating only their favorite parts of the mixed feed, thereby avoiding nutritional waste.
- Low moisture content and high density of the pellets minimize surface area exposed to air, which solves the problem of mold growth during hay storage.
2. As clean energy source
- Hay pellet fuel offers stable calorific value and complete combustion, so it can replace coal for heating or industrial boilers. As a clean energy source, it enables the circular utilization of agricultural resources.
- By converting agricultural waste into energy, we can avoid the severe air pollution and loss of soil organic matter caused by direct field burning.
- Loose hay occupies a large volume, resulting in high transportation and storage costs. When compressed into pellets, its energy density increases significantly, and approaches that of coal, which makes it more convenient for long-distance transport and centralized storage.

Precautions for Producing Hay Pellets
Producing high-quality hay pellets is a systematic process where not only the machinery itself but also operational techniques and raw materials play crucial roles. As a manufacturer specializing in hay pellet machine sales, RICHI can share some secrets to successful production.
Raw Material Selection and Combination
- Avoid the use of a single feed ingredient for a long period: Mix different types of grasses (such as hay and forage) or straws (such as rice straw and wheat straw) as much as possible. This helps balance nutrition and improves pellet formation.
- Fiber content must be controlled: Because excessive fiber will cause excessive wear on dies and reduces the output of hay pellet mill.
- Ensure uniform pellet size as much as possible: Non-uniform particle size leads to loose structure and increased breakage. Excessively coarse particles result in rough surfaces, easy breakage and higher energy consumption of the hay pellet mill.
- Control moisture content: Adjusting the moisture content of raw materials to between 13% and 18% would be a safe range. The specific optimal value varies depending on the raw material and equipment, so it requires subsequent experimentation to determine.
Machine Commissioning and Operation
- Cold Start: Conduct test runs with oily materials such as bran mixed with grease to preheat the rollers and molds. This prevents damage to the dies and rollers and helps achieve optimal operating temperatures.
- Select the correct mold cavity compression ratio: Different raw materials require dies with varying compression ratios. Fibrous materials such as grass powder and straw typically demand higher compression ratios (e.g., 1:8 or greater) to generate sufficient pressure for proper molding.
- Moisture-proof Storage: While finished pellets are resistant to mold, they may still absorb moisture. So they should be stored in a dry and well-ventilated warehouse which is protected from rain. It is also recommended to use woven bags lined with plastic bags for sealed packaging.

Hay Pellet Production Line Working Process For Large Capacity
RICHI Machinery not only offers hay pellet machines for sale but also provides complete straw pellet plant. This production line can also be used to manufacture hay pellets, straw pellets and specialized feed pellets for ruminants, which can meet diverse market demands. Below is a detailed explanation of the core process flow for the 8-12T/H hay pellet production line.
1
Raw Material Crushing—Hay Crusher
A specialized bale-breaking crusher is used to chop long-stemmed hay into 1-3 cm segments. This reduces material volume prepares it for subsequent fine grinding, and also ensures smooth feeding.
2
Drying Stage— Drum Type Dryer
Hay sections with high moisture content are fed into the drum type dryer. Inside the drum, the material comes into full contact with high-temperature hot air, which quickly evaporates excess moisture. So this process brings the material to a uniform and safe moisture content suitable for granulation.
3
Raw Material Crushing—Hammer Mill
After drying, the hay segments are fed into a hammer mill, where high-speed rotating hammers strike them into finer grass powder. The objective is to crush the raw material to a smaller particle size, which is crucial for subsequent conditioning and pelletizing. Therefore, this forms the foundation for ensuring pellet quality and production yield.
4
Pelletizing Process—Grass Pellet Mill
The tempered material is continuously and uniformly fed into the ring die chamber of the pellet mill. Under immense mechanical pressure, the material is forcibly squeezed through the die holes by the rollers, which forms dense cylindrical strands. These strands are then cut by external blades into pellets of a predetermined length.
5
Cooling System—Counter-flow Cooler
Pellets emerging from the Hay pellet mill are hot and soft, so they should be immediately fed into the counter-flow cooler. Cold air rapidly cools them to room temperature. This process sets the pellets’ shape, reduces moisture content, and hardens them for easier storage and transportation.
6
Screening Stage—Vibrating Screen
The cooled pellets contain a small amount of powder generated during transportation. They then enter the vibrating screen for separation. The vibrating screen separates qualified pellets and returns the screened fine powder to the conditioner for regranulation, which reduces material waste and improves yield.
7
Packaging Process—Weighing Machines and Automatic Packing Scales
Qualified straw pellets after screening are loaded into woven bags or bulk bags via an automated weighing system, and then sealed. Finally they are transported to the finished goods warehouse for storage.

FAQ Of Hay Pellet Machine For Sale
What is a hay pelletizer?
+
A hay pelletizer is a mechanical device that compresses crushed hay, straw, and other agricultural waste into high-density and cylindrical pellets through high-temperature and high-pressure extrusion. These pellets are convenient for storage and transportation, and can serve as high-quality feed or biomass fuel.
What is the primary purpose of producing hay pellets?
+
For feed: Enhance nutrient utilization, prevent selective feeding by livestock, reduce feed waste, and facilitate storage and automated feeding.
For fuel: Convert low-value waste into high-energy-density clean energy to replace coal.
What types of raw materials can RICHI hay pellet machine for sale typically process?
+
It can process various fibrous materials, such as alfalfa, timothy grass, Bermuda grass, rice straw, wheat straw, corn stalks, and certain agricultural byproducts.
What are the requirements for raw materials?
+
Particle size: Materials must be finely ground and usually need to pass through a 3-6mm screen. Uneven particle size affects molding efficiency and pellet quality.
Moisture Content: Typically, raw material moisture must be adjusted to between 13% and 18%. Excessively dry material is difficult to form, while excessively wet material results in soft and moldy pellets.
What is the compression ratio of a die? Why is it important?
+
The compression ratio refers to the ratio of the effective length to the diameter of the die bore.
Raw materials with high fiber content and high lignin levels (such as straw) require a higher compression ratio to generate sufficient pressure for proper molding. Selecting an incorrect compression ratio can result in low output, high energy consumption and poor pellet quality.
Is it necessary to add a binder during production?
+
Generally, there is no need. Lignin in the raw materials softens and melts under high temperature and pressure, which acts as a natural binder. However, for certain materials that are extremely difficult to form, a small amount (1-2%) of natural binders such as starch or molasses can be added to improve the forming effect.
