Size and weight
In terms of size and weight, plate compactors are always heavier than rammers. They are difficult to move and would require more storage space
Level of compaction
Tamping rammers are more powerful and compress deeper in clay soils, but they cannot be utilized in granular soils. Plate compactors are less powerful but may be used on wider areas and all soils.
Area of Coverage
The plate compactor is frequently the superior choice for compacting a broad area. The huge plate allows you to cover a considerably wider area in less time.
While a plate compactor is ideally suited to granular material, it can also be used on both cohesive and granular soil, therefore it makes little difference what soil type your huge task comprises. But, if you are compacting thick soil, you might consider compacting in layers or switching to a tamping rammer. Nevertheless, if you’re working with granular soil, the tamping rammer will produce a hole instead of properly compacting the earth, thus you’ll have to use the plate compactor one layer at a time.
Tamping rammers work well on clay soils and in limited areas. They compress the earth by impacting it. Plate compactors, which use vibration to crush gravel, sand, or silt, are best suited for bigger regions. When deciding between a tamping rammer and a plate compactor, consider the soil type and the size of the project.
