How wood chipper works

Understanding how the wood chipper works GREENMECH will help us understand and easily use, adjust or troubleshoot the wood chipper that is facing.

A wood chipper is a combination of parts, including a hopper, collar, chopper, and often a collection bin. Typically powered by internal combustion engines (although electric versions are available), they have horsepower, depending on size and type. The way a wood chipper works is an interesting combination of processes.

All wood chippers contain the same basic pieces. A motor, whether electric or gas, powers a gearbox containing a v-belt and pulley, resulting in a knife or roller that cuts, slices or coats or grinds, depending on the size and nature of the wood it receives. Most have separate troughs for the resulting product: one for wood chips and one for coatings. The more powerful the machine, the more large branches can be handled.

Here are the different handling mechanisms for the wood chipper:

Drum Chopper: Drum chopper has a large motor-powered drum inside the machine. The drums can pull the material in before cutting it then directing it to the appropriate chute. Drum choppers are fast, but noisy and require careful handling. Users must feed carefully, to avoid clogging and paper jams.

Disc Chopper: Disc chopper contains a steel disc with edges cut into blades. Wheels (generally hydraulic) move chipped material towards the rotors. Discs come in a variety of sizes and horsepower.

High Torque Rollers: Torque rollers are a common feature of electric lawn mowers. Quieter in operation than gas-powered lawn mowers, electric models are often preferred by homeowners associations and good-natured neighbors. The rollers work by crushing the material, not shredding it.

Whole tree processors or recyclers can cut branches or stems up to 6 feet wide, while Tub Grinders processes stems or branches up to 8 feet wide. They process the wood through grinding rather than cutting, shredding or grinding. They are used by professional growers, in cleaning or pruning applications.

What is the noise level for the Wood Chipper?

The noise level of the wood chipper is high.

The suction, followed by the cutting and grinding action of the blades and ejecting the material, produces not only the sound but also the vibrations that the ear records. Normally, a gas powered wood chipper makes noise at 110 decibels, which is 5 decibels higher than a saw. While phone models are generally quieter than gas-powered models, which have an output of about 85 decibels, they are still considered noisy enough to warrant hearing protection. Prolonged use often happens to workers, or even homeowners who simply rent a machine for the day.

Continuous, frequent use without hearing protection can lead to gradual hearing damage. Therefore, operators are advised to use earmuffs or earplugs, preferably a custom fitted type.

Keep the wood chipper running smoothly

Taking care of your wood chipper after purchase is important to ensure you get years of use out of your equipment.

Brush chiller service technician at GREEN MECH, recommends that following these two valuable guidelines make a significant impact in promoting durable and powerful machine performance.

First of all, he recommends lubricating the cutter drum or disc bearings after use, when the machine is still warm. New grease should be applied until the old grease emerges. Performing this task removes debris that could potentially damage the machine and removes moisture that can corrode the bearings.

Second, it is imperative to inspect the knives after each use to confirm that they are not damaged. Look carefully for accumulated debris. The knives provide the machine’s most important cutting performance, so they must be carefully maintained to operate in top condition. If you delay until function is reduced, your productivity will decrease and the bearings will suffer. Also, be sure to periodically confirm that the torque on the tool mounting hardware is sufficient according to the operating instructions.

GREEN MECH also recommends that daily brush chiller owners/operators should pay regular attention to the engine bay and radiator.

With the rise of new emissions standards, higher engine operating temperatures are common, thus requiring larger radiators. Making sure that the radiator is not clogged is essential to avoid overheating the engine which could lead to shutdown. Blowing out the engine compartment helps reduce high temperatures and “fines” that can pass through the radiator.

Too much debris behind the feed roller will prevent full operation. To restore your machine to its pre-sludge standard, deploy an air compressor or leaf blower. The fact is that clean machines always run better. After the machine has been cleaned, you can easily confirm that all shields, switches, control bars and docking components are healthy.

Finally, take a walk around the machine before operating it. Note any aspect that can reduce productivity, such as loose hydraulic lines, clamps or fittings, worn hoses, or missing hardware. Then make the repair or arrange for it to be done professionally.

Taking care of the whole chopped tree is more involved. It is important to make sure all knives are aligned with a suitable adjustable anvil. Imperfect knife and anvil maintenance reduces fuel economy and production and causes machine wear due to increased vibration due to incorrect shaft placement. Therefore, every time the tool is sharpened or changed, the anvil must be readjusted to ensure the proper clearance.

How to fix a clogged chiller

How to fix a clogged chiller is a common concern of many machine owners. Severe cases of congestion may require a visit to your local service department, but there are steps you can take to clear the blockage independently.

1. The first step you must disconnect the spark plug to make sure the machine is off and will not restart while you work. Doing so will help you avoid serious injury.

2. Next, unlock and lift the exit chute guard to display the exit screen. When the screen is free from the bar, remove any and all material from the chute. Since the spark plug has been removed, you can use your hands to make larger pieces. For smaller pieces of material, long nose pliers will assist you in cleaning the area completely.

3. Once the metal screen protector is clean, you’ll want to test the chiller for full functionality. To do so, lower and lock the exit rail. Replace spark plugs only when you are sure that all material has been removed and your hands and clothing are safely away from the machine. After the spark plug is put back into service, you can try restarting the shredder.

If restarting is easy and the slide is clearly unusable, you can proceed to the next steps.

1. First, as always, remove the spark plugs again. Even when you’re feeling down, safety always pays off.

2. Unlock and lift the exit door again. Next, remove the metal screen. Usually it has two long bolts at the top and bottom that hold it in place. This step may require some effort; remember to pry gently rather than forcefully pulling the screen out once the screws have been removed.

3. Because the screen is not duplex and/or reversible, store it in a way that allows you to remember which side should face out.

4. You can now pull the starter cord to expose the hoses and hopefully get access to the rest of the blockage. Persevere to pull a few more inches, then stop, find more clogs. Reach out and knock out anything you can find.

Continue this process, taking special care to release your hands between pulls. Keep repeating the dragging and searching process until all the scaly areas are completely clear. Deleted sails will collide with each other as they react to a turn.

At times, shredders and shredders clog in a similar way to lawn mowers, when wet material accumulates inside the mower. When this happens, follow these steps:

Lower the exit chute and lock it in place. Keep screen saver during this time. Reconnect the ignition wire. Try to start the shredder. If it doesn’t start right away, be patient, as each start attempt forces the chiller/cutter to release more dry or lumpy material.

After the engine catches, let it run for a few minutes. Then, turn it off before reinstalling the exit guard and tightening the bolts. Finally, lower the exit chute and lock it in place.

If your machine is working, continue doing what it is doing, avoiding any previous material clogging up the chute. Wet bark can cause problems for choppers and shredders. Work may need to be deferred until the wood in question is dry, that is, when the bark is brittle and does not shed each wire.

If none of these attempts clear your machine, you may need to seek the assistance of the service team for your particular chiller brand. Not only can they repair or remove any remaining blockages, but they can also determine if your machine is malfunctioning due to another issue.
