When talking about ring die pellet machines, vertical ring die pellet mills and horizontal ring die pellet mills are two common choices. They have unique advantages and application scenarios when processing wood pellets in biomass pellet production plants. Vertical ring die pellet mills shine in specific industrial applications with their high efficiency, while horizontal ring die pellet mills are favored for their stability and adaptability. This article will delve into the differences between vertical ring die pellet machines and horizontal ring die pellet machines, and provide you with honest advice on choosing and buying a ring die wood pellet mill to setup your own biomass pellet plant.
Vertical Ring Die Wood Pellet Machine & Horizontal Ring Die Wood Pellet Machine
Differences between Vertical and Horizontal Ring Die Pellet Machines
Although there are many differences between vertical ring die pellet mills and horizontal ring die pellet mills, they are the same in the basic composition of these two ring die pellet making machines.
- Drive System and Transmission System. The main parts are the electric motor, drive shaft, gear, or V-belt drive assembly.
- Molding System. The main parts are the raw material pretreatment bin, molding cylinder (molding cavity), and pressure roller (pressure roller).
- Feeding and Unloading Part.

Operational Principles Impact Pellet Making Methods of Ring Die Pellet Press
Vertical Ring Die Pellet Mill processes raw materials into pellets by pressure and friction inside the die, where the raw materials fall vertically and are extruded by the pellet mill die and rollers to form pellets.
Horizontal Ring Die Pellet Mills process raw materials into pellets by pressure and friction inside a die, where the pressure and cutting device inside the pellet mill ring die help to make the pellets into the desired size.
Ring Die Spindle Orientation Affects Raw Material Distribution
The names Vertical Ring Die Pellet Mill and Horizontal Ring Die Pellet Mill are derived from the positioning of the ring die spindle. In a vertical ring die machine, the spindle is placed vertically. The raw material, through the upper feed opening enters, falls straight down into the pre-pressurized bin directly by its own gravity. Inside the pre-pressurized bin, the rotor evenly distributes the raw materials to the molding chamber to ensure uniform distribution of raw materials.
In the horizontal ring die pellet machine, the main spindle is placed horizontally. Although the raw material is also fed into the pre-pressurized chamber from the upper feeding port, the raw material needs to enter the pre-pressurized chamber at a sideways inclination due to the rotation of the rotor in a vertical plane. This results in an uneven distribution of the material in the pre-compacted bin across the inner wall of the ring mold. In the pellet mill ring die below and the side of the ring die upward rotation, the distribution of raw materials is more; while in the pellet mill ring die above and the side of the ring mold downward rotation of the distribution of raw materials is less. This uneven distribution leads to uneven force and wear on the rollers.
Pressing Methods Influence Particle Formation Rates of Ring Die Pellet Machines
In the vertical ring die pellet maker machine, the press wheel is rotating while the mold remains stationary, so that the biomass pellets will not be affected by the secondary flinging. Therefore, the length of the pellets pressed out by the vertical ring die pellet machine is basically equal, and there is almost no pulverization, which makes the pellet forming effect reach 99%.
In the horizontal ring die wood pellet machine, the mold rotates while the press wheel is stationary, and the high-speed rotation causes the pellets to move along with the mold, which is easy to suffer from flinging crushing, and is prone to cause uneven length of the pellets or chalking phenomenon.
Differences in the nature of biomass pellet raw materials directly affect the operation of the wood pellet press machine. Density, humidity, particle size and other characteristics of different raw materials need to be fully considered in the purchase of biomass pellet making machines to ensure production stability and efficiency. We welcome free consultation and support to send raw material samples to our factory for trial production to find the most suitable pellet processing equipment solution for your raw material characteristics.
Applicable Scenarios Based on Production Efficiency of Ring Die Pellet Mills
Usually, the speed of the vertical ring die is 75rpm, while the speed of the horizontal ring die granulator is over 200rpm. Fast speed has low torque; slow speed has high torque. Therefore, the vertical ring die pelletizer machine is more suitable for processing materials that are difficult to bond and mold, such as rice husk, rice straw, and hardwood timber from South and Southeast Asia. On the other hand, thanks to its horizontal structure, horizontal ring die pelletizer machine is more suitable for processing wet, sticky materials, as it is better able to deal with poor material flow as well as easy cleaning.

Different Ring Die Pellet Machine Design Lead to Different Maintenance Costs
- Maintenance Methods for Ring Die Pellet Mill Templates:
The template of vertical ring die pellet machinery can be directly disassembled for cleaning and replacement, which makes maintenance easier. And vertical ring die is a double-layer die structure which makes it possible to replace only part of the mold instead of the whole mold when replacing the mold. In contrast, horizontal ring die pellet machinery, with single-layer die, needs to be disassembled to maintain the template, which increases the difficulty and cost of maintenance.
- Adjustment Methods for Rotor and Template Clearances:
The rotor and template gap of the vertical ring die pellet processing machine can be adjusted by adjusting the pressure wheel, so maintenance is relatively convenient. However, the horizontal ring die manufacturing pellet machine needs to replace the template or adjust the position of the cooler to adjust the gap, which increases the ring die wood pellet press machine maintenance cost.
Buying Ring Die Pellet Machines: Ultimate Biomass Pellet Plant Investment
Conducting a wood pellet business plan is a task that requires a lot of thought, especially when considering the operation of a pellet mill. As a ring die pellet mill supplier, I should tell you something about setting up a pellet production line equipped with ring die pellet processing machinery. The usual output of a ring die machine is in the range of 1 ~ 2.5 tons/h. This means that even in a large pellet plant, 2 or more large industrial ring die pellet mills are usually sufficient for large-scale pellet production. A small ring die pellet mill or a mini ring die pellet mill is also sufficient for a small wood pellet plant.
