Known for its low investment cost, energy efficiency, high productivity, and simple maintenance, this machine is widely used in wood and charcoal processing plants.

Available with various screen sizes to meet different sawdust requirements, the hammer mill is a globally recognized solution, with installations in countries such as India, Brazil, Kenya, and Turkey. For more information and customization options, please contact us.

Applicable raw materials for charcoal crushing machine

Before diving into the specifics of the charcoal crushing machine, let’s first explore the raw materials it can process.

Charcoal crusher is used in a wide range of applications. Shuliy Machinery has summarized the following types of common raw materials based on the purchases of our customers in the past.

Wood

The raw materials generally include branches, logs, leftovers of wooden furniture, waste boards, bamboo, corn stalks, hay, coconut shells, peanut shells, etc.

However, for very large wood, it is generally first processed into wood chips by a drum chipper, and then crushed by a hammer mill. The final sawdust size is about 3mm.

Grains

The raw materials in this category are various grains, such as corn, oats, sorghum, etc.

Hammer crushing machine shreds them into fine powder about 1mm. These grain flours can be mixed and shaped to make animal feed. 

Charcoal

The hammer mill can also pulverize charcoal, coconut shell charcoal, and bamboo charcoal into charcoal powder of about 3 mm, which can be used to make hookah charcoal and barbecue charcoal.

With an understanding of the raw materials, we can now examine the key components that make up the charcoal crushing machine and their functions.

Main structures of charcoal crushing machine

The wood pulverizer mainly consists of feeding hopper, hammer, screen, fan, collecting drum, cyclone dust collector, machine stand, motor, and so on. The hammer, screen, and tooth plate are in the crushing chamber.

To accommodate varying sawdust size requirements, we offer a range of sieving screens based on customers’ specific needs. Standard sawdust size is 6mm, with the finest achievable size being 1mm.

The cyclone dust collector effectively handles dust removal. Additionally, we provide customization options to meet your unique requirements. Please feel free to contact us for further consultation.

How does a hammer crusher work?

• Material enters the crushing chamber evenly through the feed inlet.
• The wood pulverizer breaks the raw materials using a high-speed rotating hammer.
• Continuous airflow moves the broken materials along the outer edge of the rotor.
• Materials pass through the sieve holes of the screen.
• Broken materials are transported out of the machine.
• An optional storage bag or silo can be added for convenient collection.

What are the types of hammer mills?

Model	WD-HM60	WD-HM70	WD-HM80	WD-HM90	WD-HM1000	WD-HM1300
Power(kw)	22	30	37	55	75	90
Hammers(pcs)	30	40	50	50	105	105
Fan(kw)	/	/	7.5	7.5	11	22
Dust remover(pcs)	5	5	5	5	14	14
Cyclone diameter(m)	1	1	1	1	1	1
Capacity (t/h)	0.6-0.8	1-1.2	1.2-1.5	1.5-3	3-4	4-5

Hammer mill models are named according to the width of the machine’s shaft. For instance, the WD-HM60 model has a shaft width of 60 cm.

The WD-HM60 and WD-HM70 models are popular choices for small wood processing plants because of their suitable output and compact size. In contrast, large forest farms often opt for the WD-HM1300 due to its high output capacity.

Wood hammer mill advantages

Inside the wood pulverizer, raw materials are crushed by the high-speed operation of the hammer.

• The hammer operates at twice the speed of an ordinary mill.
• This results in higher work efficiency and stronger production capacity.

The cost of a charcoal crusher is low, with minimal energy consumption.

• Finished products can be continuously processed into other products.
• This significantly improves profit margins.

The hammer mill can be equipped with:

• A cyclone
• Dust bags

We offer a variety of sieving screens to meet different customer needs.

For handling hard materials or specific feeding port size requirements:

• We can provide an additional feeding port.
• We can enlarge the existing feeding port.

Operating tips of hammer mill machine

To maximize the advantages, proper operation is essential. Here are some practical tips for effectively using the hammer mill machine.

• Carefully read the manual before using the wood pulverizer.
• Remove sand, stone, metal, or other debris from the materials to avoid damaging the hammer mill crusher.
• Idle the machine for 2-3 minutes to clear any remaining material when stopping.
• The operator should stand to the side of the feeding mouth and avoid reaching into the machine.
• Ensure the screen and body are tightly fitted to prevent material leakage and maintain quality during operation.
• Do not open the cover while the charcoal crushing machine is running.
• Avoid starting the motor under load or operating it under overload conditions.
• It is forbidden to manually feed hard wooden sticks or iron bars when the feeding mouth is blocked.

Maintenance of hammer crusher for sawdust making

Proper maintenance ensures longevity and efficiency, so let’s review how to maintain the hammer crusher to keep it in optimal condition.

1. Regularly grease the bearings.
2. If the hammer crusher will be inactive for an extended period, clean it thoroughly inside and out and store it properly to prevent rust.
3. If unusual noise occurs during operation, stop the machine and check for ironstone, or any fallen or damaged components. 

Usages of final crushing products

With a well-maintained machine, you can make the most of its output. Explore the various uses of the final crushing products, such as in biomass briquettes, wood pellets, and more.

Biomass briquettes and charcoal production

• Sawdust can be pressed into sticks using a biomass briquette machine.
• These sticks can then be carbonized in a furnace to produce charcoal briquettes.

Wood pellets and board production

• Sawdust can be used to produce wood pellets.
• It is also suitable for manufacturing particleboard, sawdust board, and high-density board.

Livestock feed and fertilizers

• Corn cobs, stalks, and forages can be milled to create livestock feed.
• These materials can also be processed into fertilizers for land application.

Paper recycling

• Paper scraps can be recycled to make new paper.
• Waste paper scraps can be processed into recycled paper products.

Scenario application of hammer mill

Hammer crushers are often used in complete production lines in conjunction with other machines.

For example, in the charcoal briquettes production line, due to the relatively small size of the feeding port of the biomass briquette machine, the large wood is usually roughly broken by a drum chipper, and then finely broken by a hammer mill.
