BIOMASS HAMMER MILL FOR SALE
Hammer mill for biomass are commonly used biomass raw material pretreatment equipment in biomass pellet and briquetting production lines.
The biomass hammer mill, also known as the biomass crusher, reduces biomass and agricultural waste to a fine size (usually within 10 mm). The biomass hammer mill mainly consists of the feeding system, the hammer milling machine main part, the discharge system, and the dust collection system. It’s widely used in biomass pellet production lines, cement factories, power plants, wood processing, and agricultural waste recycling. Depending on the type of raw material, output size, and capacity, it can be available in various models to meet different scales and production needs. In most cases, a hammer mill for biomass is designed for crushing biomass raw materials to meet the requirements of pelleting or briquetting.
BIOMASS HAMMER MILLS TYPES AND SERIES
Small Hammer Mill
Small biomass hammer mill typically have a power output of less than 30 KW and a production capacity of less than 1,000 kilograms per hour. They are compact in structure, have low investment costs, and are designed and developed specifically for homeuse, small farms, various small factories, and some experimental projects.
Straw Hammer Mill
Straw hammer mill are commonly used in straw pelleting or briquetting projects and are widely used in markets such as India and Africa. Straw has low density and high toughness, resulting in a very low bulk density after crushing. To accommodate these characteristics, the feeding system, hammers, screens, and suction system of the straw crusher need to be specially designed.
Wood Chips Hammer Mill
From wood chips to sawdust, this is a highly efficient and professional specialized machine designed specifically for wood chips of varying hardness and moisture content. The sawdust with 15 mm in size and are typically sold to power plants or cement plants as fuel. Please note that the machine's output is directly related to the original size of the wood chips; therefore, we need to confirm the size, thickness, and moisture content before moving forward.
Wood Pellet Hammer Mill
The industrial hammer mill is designed specifically for industrial projects involving large-scale biomass pellets or briquettes. This machine features a heavy-duty rotor design and belt drive. Various screen shapes can be designed to suit different raw materials, resulting in a lower failure rate, robust structure, and 24-hour continuous operation. It is suitable for various medium to large-scale biomass fuel pellet production projects.
Wood Hammer Mill
From wood logs to sawdust directly, the wood log hammer mill combines chipping and crushing functions and can crush wood logs within 20cm in diameter to fine sawdust with a 10 mm size. Compared with using a wood chipper and a hammer mill as two sets of machines, this machine can save space and also save labor costs. It with chipper and crushern roller both.
Agricultural Hammer Mill
Many crops are not initially crushed and are quite long. To improve material feeding, this crusher has been equipped with a forced feeding device, which can accommodate straw or large leaves (such as palm leaves) up to 2 meters in length. This solves the problem of material blockage caused by uneven feeding and is especially suitable for larger materials.
HOW DOES A HAMMER MILL WORK?
The working principle of hammer mill is to use a high-speed rotating rotor to drive the hammers to crush the fed raw materials to the size specified by the screen. The complete biomass hammer milling system consists of an underground automatic feeder, the feeding belt conveyor, a hammer mill main unit, the discharge system, a control panel, and the dust collection system. These components work together under the automatic control system to achieve a complete processing flow from raw material conveying and crushing to discharging finished crushed raw material.
① Underground Automatic Feeder
The underground automatic feeder is the first part of the hammer mill system, which is mainly used for feeding raw material continuously and evenly. Compared with manual feeding, the automatic feeder can maintain a stable feeding speed; you only need to arrange a loader to push the raw material to the feeder. It can help avoid biomass hammer mill blockage or low output caused by uneven feeding, improving the milling machine efficiency. The feeding speed can be adjusted automatically by the control system, as it is equipped with an automatic start and stop sensing system.
② Biomass Feed Conveyor
The feed belt conveyor is used for continuously feeding raw materials from the automatic feeder to the biomass hammer mill main part, providing a stable material supply for the equipment. By adjusting the conveyor speed, the feed rate of the hammer mill can be effectively controlled, reducing clogging. For some very loose and light raw materials, the conveyor needs to be equipped with uniform rollers.
③ Biomass Hammer Mill Main Part
The hammer mill is the core equipment of the entire biomass crushing system. The hammer mill works on the principle of high-speed punching and crushing the raw material. When the biomass materials are fed into the crushing chamber, the high-speed rotating rotor drives the wear-resistant blades to crush large-sized material like wood chips, straw, and other biomass waste into smaller dust-sized material. Once the material reaches the required size ( sieve hole decides), it is discharged through the inner sieve to the discharging conveyors.
④ Dust Collection System -3
During the milling process, fine dust is very easily generated. Therefore, industrial-grade biomass crushers should be equipped with dust removal systems, mainly consisting of a cyclone system and bag dust collection system. The combined use of cyclone dust collectors and bag filters improves dust removal efficiency, making the equipment more suitable for continuous, environmentally friendly biomass processing production lines.
⑤ Discharge System
The crushed material is conveyed to the next production stage via a cyclone separator or a screw conveyor. Depending on the characteristics of different raw materials, the unloading system can be composed of a combination of a cyclone separator and an auger, or it can use only a cyclone separator. Cyclones are mainly suitable for light-density materials, while augers are more suitable for heavy -density materials.

HOW TO CHOOSE THE BEST BIOMASS HAMMER MILL?
Choosing a suitable biomass hammer mill is challenging for many beginners, as an unsuitable machine will lead to wasted time and money on adjustments. If you are selecting a hammer mill, we would like to provide some advice based on over 20 years of production experience.
1. Select a hammer mill based on your raw material moisture content and initial size
First, you should determine the type, moisture content, and feed size of the raw material you intend to use. Different raw materials, such as wood, wood chips, sawdust, straw, empty fruit bunches (EFB), and coconut shells, have different requirements for hammer mills. For wet materials with a moisture content of approximately 30%-40% or even higher, choose a hammer mill specifically designed for high-moisture materials to reduce the risk of inner sieve clogging. For large pieces of wood or wood chips, a mill with a large feed opening and a robust structure is required, and pretreatment may be necessary.
2. Select the biomass hammer mill based on the actual capacity you need
Meanwhile, the applicable scenarios, output, operating time, and degree of automation also need to be considered. Small farms or small-scale production can choose small crushers, while industrial production such as biomass power plants and wood pellet plants should choose heavy-duty equipment with high output and continuous production, and be equipped with automatic feeding, automatic start-up and shutdown, conveying and dust removal systems to improve production efficiency and operational stability.
The hammer mill is a key piece of equipment in a pellet production line, directly affecting the normal operation of the entire production line. If you require any technical support, please feel free to contact us. We are dedicated to helping you.
