Multifunctional Hammer Mill

Brief Introduction

TONY multifunctional hammer mill is a general-purpose crushing device with a high-speed rotating hammer as its core working component, pulverizing a variety of materials through impact, collision, and grinding. It integrates multiple crushing functions to meet the crushing needs of materials with different properties and particle size requirements, and is widely used in agriculture, industry, energy, and other fields.

With its wide material adaptability, flexible particle size control, and efficient crushing performance, the multifunctional hammer mill has become a key piece of equipment in material pre-processing across various industries, significantly improving the convenience and cost-effectiveness of material processing.

Working Principle

Impact Crushing: The multifunctional biomass hammer mill primarily operates based on the high-speed impact crushing principle. After biomass material enters the crushing chamber through the feed inlet, the hammers mounted on the rotor, driven by the high-speed rotation of the rotor, impact the material at an extremely high linear velocity, crushing any large biomass particles.

Sieving and Secondary Crushing: Centrifugal force propels the crushed particles toward the screen. Powders that meet the required particle size pass through the sieve apertures and become the finished product. Particles that do not meet the required particle size remain in the crushing chamber, where they are repeatedly struck and ground by the hammers until they reach the desired particle size and are discharged through the screen.

The Pellet Production Line

Wood is the most common raw material for wood pellet production.

So, how do you design a suitable wood pellet production line using wood as the raw material?

First, a drum wood chipper is used to shred the wood into 2.5-3.5 cm chips.

Then, a hammer mill is used to grind the chips into sawdust (6-12 mm).

Sometimes, a dryer is also required, as wood typically has a moisture content of approximately 30-50%. In this case, a dryer is necessary.

Then, a vertical ring die wood pellet machine is used to press the dried wood chips into high-quality wood pellets.

After cooling, the biomass pellets are packaged and stored to facilitate transport and sales.

The above outlines the basic process of wood pellet production. It is important to note that safety protocols must be observed during actual operations, and the relevant equipment requires regular maintenance to ensure production efficiency and product quality.
