There are 2 kinds of hammer mills: small hammer mill used with small pellet mill; large hammer mill used with large pellet mill.
It is almost the most indispensable part for biomass pellet making.
Small hammer mill
Small hammer mill is a basic part in small pellet plant.It can process corn, corn straw, peanut shell, bean straw, branches etc, materials with less than 14% moisture content.
Working Principle of Small Hammer Mill
When the materials go into the chamber of the hammer mill, they will be crushed by the high-speed of rotary hammers. The crushed materials are along the outer edge of the rotor under the function of centrifugal force and smashed by the squeezing, crashing, striking of the hammer, toothed plate and screen. The smashed materials are sent out of the hammer mill under the function of rotor and draught fan. The particles that don’t pass through the screen hole will be left in the hammer mill repeating the above steps until they are sent out of the hammer mill.
| Model | Power | Size(mm) | Net weight (kg) | Spindle Speed (r/min) | Screen | Capacity (kg/h) |
|---|---|---|---|---|---|---|

This kind of hammer mill can process crude fiber and large bulk materials, such as twigs, bark, plant roots, wood chips, garbage and chemical waste, etc.
Large Hammer Mill
In the complete pellet mill plant or complete briquette plant, hammer mill is an normal equipment because that there are few materials can be processed into pellets or briquettes directly. They usually need to be ground into proper size by the grinder that they can be processed into pellets or briquette machine.

SFSW Series Sieve-free Hammermills
The SFSW Series Sieve-free Hammermills combined with air separator or grading sieve can enhance the efficiency of crushing greatly. The SFSW Series Sieve-free Hammermills use 360° metal scaleboard, free of sieve. Even if there are impurities such as iron nails, bolts, the machine won't be damaged.
Our hammermill is very suitable to pulverize the material that easily blocks the sieve or very fine material.
Our hammermill save money and energy consumption.

Features of Hammermill:
- - are able to produce a wide range of particle sizes.
- - work with any friable material and fibre.
- - ease of use.
- - lower initial investment when compared with a roller mill.
- - minimal maintenance needed.
- - particles produced using a hammermill will generally be spherical, with a surface that appears polished.
