How Fast Does a Wood Hammer Mill Spin?

The speed at which a wood hammer mill machine will spin depends on the model you have. Well, expect the bigger ones to crush the wood faster than the small wood hammer mill.

Each wood hammer mill has knives or hammers. These knives rotate at speed starting from 2500 RPMs to even more than 60 000 RPMs. Remember, these knives or hammers move at high speed to make the materials very small and faster.

With these speeds, they can move clockwise or anticlockwise. It will depend on the motor’s size. Also, the electric wood hammer mill makes the pellets faster than the diesel ones.

Wood Hammer Mill’s Working Principle

It won’t matter the type or function of the wood hammer mill; they all work in the same way. But, it’s only the size and purpose of the wood hammer mill that can differ.

Remember, it’s simple with how the machine works. So, read on to see the hammer mill principle. You’ll know how it works even before you buy it.

Design of the Hammer Mill for Wood

Here, we’ll look at the parts that make this machine work. It doesn’t matter if it’s electric or uses diesel. Every wood hammer mill has five main features.

Remember, the size of each part won’t be the same on every wood hammer mill. But each piece plays a vital role in the machine.

The parts include the feeding plate, crushing area, delivery device, screens, and rotor. So, below is the info on the function of each piece.

1. Feeding Plate

Every hammer has a feeding area. It’s where you place the wood or biomass materials you want to crush.

How the feeding plate will work depends on the design. Some can use gravity to take in the materials. Others use the meter or electric power.

Most firms use electric wood hammer mills. So, the feeding plates have a meter to allow the materials to be uniform even as you crush them.

When you buy a small wood hammer machine, the feeding plate will use gravity to take in the materials. Don’t expect the wood materials to enter uniformly.

2. Crushing Room

After coming from the feeding plate, the wood cravings will go to the crushing part. Here, you’ll get hammers or crushing knives.

They move very fast. It’s from this movement that the machine crushes the wood into pellets.

These knives and hammers are on the horizontal shafts. As they crush, they can either move clockwise or anticlockwise.

The blades have high-quality steel. It makes them last for a long time and be free of wear. Also, the air blower works as a cooler.

The screens will determine the size of the particles that come from the crushing room. Remember, most wood hammer mills have many screens meshes.

All screens are in a given order. This arrangement helps in giving you fine pellets.

3. Delivery

This part receives the pellets or wood shavings after you crush them. At this point, you can make your wood cravings or pellets even finer.

Also, here will depend on the type of wood hammer mill you use. The electric ones will deliver better than the hammer mill for wood that uses a diesel engine.

4. Control Zone

This part of the wood hammer mill allows you to control how the machine works. It’s where you can power it on and off. Also, it’s from here that you’ll handle the speed at which the feeding plate takes in the materials.

5. Rotor

This part rotates as a shaft together with a motor. It’s the part that holds the blades or hammer.

Some wood hammer mills have belts. These belts help reduce cases of a shock to the crushing tools.

How the Wood Hammer Mill Works?

The diagram of how every wood hammer mill works varies with the size and purpose.  But here are basic things similar to every hammer mill for wood.

• You’ll first place the wood material through the feeding part. Remember, these materials should be in the correct sizes. Also, they should have the right looks that match what the machine can crush.
• After going through the feeding chamber, they’ll head to the crushing area. It’s here that the major work begins.
• Once again, the speed at which these materials move is by the help of gravity or electric power.
• At a very high speed, the blades or hammers will hit the wood items many times. This act will help reduce them into tiny particles within a short time.
• The speed at which the machine crushes these materials depends on the diameter of the materials. Also, if it’s an electric wood hammer mill, expect things to be a bit fast.
• Then, the materials will go through the screens. It’s where they become finer. The pellets or particles that aren’t fine go through the nets again.

Picking the Best Wood Hammer Mill for Pellet Making

If you want the best wood hammer mill to make pellets, it shouldn’t worry you. The process is easy. You’ll only have to look at the following things.

1. Hammer Mill’s Capacity Calculation

Make sure your machine can crush wood and make pellets.  Every wood chipper hammer mill has instructions on them. One of the things is the rated capacity under normal conditions.

Buy a wood hammer mill with a higher production level than the number of pellets you want to make. Things will still run well even if your machine gets to wear, which makes the process stop.

But sometimes, it can be hard to understand the miller capacity. Know that the larger the mill, the high its ability it will have. But here’s a table to help you calculate the capacity.

Wood Hammer Mill’s Capacity(ton/h)	Power in Kilowatts	Weight in Kgs	Size (mm)
1 to 3	22	860	1310 by 800 by 1070
2 to 4	37	1350	1380 by 800 by 1010
3 to 6	55	1520	1900 by 800 by 1100
5 to 8	90	1830	2100 by 1700 by 1500
3 to 10	160	2300	2100 by 1000 by 1100

2. Materials to Use

The materials you will process on your hammermill can also affect what you’ll pick on as your machine. Well, since wood is a rigid material, buy a wood hammer mill with a non-sieve grinder.

If you are going to mix the wood with small particles, use a special non-sieve grinder. You’ll make the best pellets.

3. The Power of the Machine

The power that a wood shavings hammer mill or a woodcutter hammer mill uses is vital. Remember, this power level will depend on the type of material you’ll use to make the pellets.

Look at the size of the screens. It will show you the power of the machine you want to pick.

4. Discharge Means of the Wood Hammer Mill

If a machine can put away the raw materials well, go for it. Most of the excellent wood hammer mills use the self-weight way. You’ll have an easy time as you make the pellets.

• As the machine starts to run, place the wood material in the feeder. It’s after you feed the materials into the feeder that the hammers will grind them. Inside the drum, the hammers can swing fast as the rotor spins.
• After the crushing, the materials will go into the screens. It’s where they’ll get finer.
• The screens will remove the fine ones. You’ll now collect the materials as you move on to the next step of making pellets.

Maintaining a Wood Hammer Mill
