9 Different Types of Compactors

Different Types of Compactors

Compaction of soil can be done with a variety of machines. The different types of compactors have specific material and operating range that is most cost-effective.

By selecting the most appropriate device, the work will be completed more economically and efficiently, with fewer passes, less fuel consumption, and less time spent on the job.  

Compaction is a task that is frequently necessary for most construction projects. Compaction is removing any air bubbles in the soil to make it compacted.

However, this will increase the soil’s bearing capacity, allowing it to withstand higher loads without failure.

Well, some of the different types of compactors used are;

1. Rammers

Rammers are hand-steered, machine-powered tiny machines that tight small areas by causing an impact on the soil. They are lighter in weight so that a single person can wield them.

Additionally, the rammers’ bases are typically smaller, ranging from 15 x 15 cm2 to 20 x 20 cm2. Their weights usually range from 30 kg to 10 tons.  

These rammers can weigh up to two or three tons and can fall freely from heights of one or two meters to smash the rock underneath them in the case of rock compaction.

Furthermore, rammers are ideal for compacting cohesive soils such as clays in limited spaces such as ditches and building foundations. 

2. Smooth Drum Rollers

The Smooth drum rollers are one of the different types of compactors. They condense gravel, rocks, sand, and asphalt with static pressure, vibration, and impact.

They work best on granular materials ranging in particle size from giant pebbles to small sand.

Additionally, many road construction projects use smooth drum compactors to provide flat and smooth surfaces. They are one of the most commonly rented types of road rollers.  

Furthermore, smooth compactors can be equipped with optional Padfoot shell kits for enhanced adaptability, allowing soft drum rollers in Padfoot applications with limited performance.

Single drum rollers and double-drum rollers are the most common smooth roller variants. 

3. Cylindrical Rollers

A cylindrical roller is one sort of walk-behind roller. These are traditional because they are pretty light and are pushed by someone.

All other rollers on this list have walk-behind and ride-on versions, and engines are still used occasionally.  

Additionally, Cylindrical rollers are primarily used for modest, personal projects such as yard work. The diameter of cylindrical rollers is usually 1 meter, and they are composed of iron, stone, or concrete. 

4. Grid Rollers

The Grid Rollers are also one of the different types of compactors. These rollers are made up of steel grid cylindrical surfaces connected by a network of steel bars.

Square holes make up the grid. Additionally, the grid’s weight can be increased by putting ballast in the cylinder.  

With ballast, their weight typically ranges from 5.5 to 15 tons. Weathered rocks and thick soils are compacted with grid rollers. Clayey soils, silty soils, and uniform soils, on the other hand, are not suited.

However, they are primarily employed in constructing subbases for road projects. 

5. Sheepsfoot Compactors

A sheepsfoot pad is a cylindrical object that is typically 8 inches long. Padfoot compactor pads are oval or rectangular and tapered, whereas sheepsfoot pads are circular.  

Furthermore, the pad face of a sheepsfoot is smaller than the padded base, which is a significant distinction. Sheepsfoot drums have places that pierce the upper lift and condense the list below.  

When a pad is removed from the earth, it fluffs or kicks up the material. As a result, there is a loose layer of fabric on top of everything.

Additionally, the top lift will be fluffed as more fill is distributed, and the last layer will be compacted. A sheepsfoot compactor compacts material from the ground up. 

6. Pneumatic Tired Rollers

Pneumatic tired rollers are one of the different types of compactors. They are made up of a platform with two axles. Compared to the front axle, the rear axle features one more wheel.  

Furthermore, the total width of all the inflated tires is roughly equal to the width of the rollers by 80 percent. On soils, they are not often used. Instead, their ideal application is in areas where the surface to be rolled is not as rugged or steep as road asphalt. 

Additionally, the pneumatic tire roller is perfect for compacting soils with little or no cohesion. These soils are gravels, sands, clayey sands, silty sands, and even sandy clays.

They apply pressure distributed across a broader region, which prevents the ground from collapsing. 

7. Vibratory Rollers

Smooth wheel rollers (single and double drums) are nearly identical to vibratory rollers, except for one key difference: vibratory rollers have a specific vibrating component.  

Additionally, the roller will shake as it compacts and flattens the surface. Because earth, asphalt, and concrete all have natural empty spaces, they can cause a structure to bend and sink, causing structural damage.  

Furthermore, when it comes to construction projects, using a vibratory roller can help maintain the structural integrity of the building. Crushed rock or gravel are two more soil forms that vibratory rollers excel at compacting. 

8. Pad Foot/Slash Presser Rollers

The roller resembles that of a sheep’s foot roller. They do, however, have lugs on their cylinders that are larger than sheep foot rollers’ feet.

They’re also known as tamping rollers, and their static weight ranges from 15 to 40 tons.  

Additionally, they can condense to a higher degree than sheep foot rollers. Furthermore, they can also break down big chunks of soil and operate at rapid rates.

They’re great for compacting grounds that aren’t too loose. These are also one of the different types of Compactors. 

9. Plate Tampers

Plate compactors, also known as plate tampers, are used to compact sub-foundation and asphalt on driveways, parking lots, and rehabilitation projects.  

Furthermore, they can also be used in tight spaces where a larger roller would not reach. Plate compactors are divided into single plate compactors, reversible plate compactors, and high-performance/heavy-duty plate compactors.  

Additionally, Single plate compactors only compress in one direction and are the most common choice for smaller asphalt tasks. Reversible plates can be used in forward and reverse trends, and some even have a hover function.  

Reversible and high-performance/heavy-duty plate compactors are frequently employed for subbase or higher depth compaction.

However, the base plate’s design is occasionally considered, as a curved plate makes turning easier and prevents the plate from scraping the asphalt.  

Furthermore, An anti-vibration handle is a novel feature on some plate compactors. The anti-vibration handle reduces vibration transfer from the container to the operator, increasing operator comfort. 

Conclusively, try and get in touch with the correct specialists who will guide you effectively before purchasing the suitable compactor for your project.

Each machine has its own set of benefits and drawbacks, so it’s critical to make an informed decision.
