You probably already know how expensive concrete grinder machines are if you’ve done any market research on surface preparation and concrete polishing. It’s crucial to ensure we obtain exactly what we need, receive the appropriate value, and purchase the best product, as with many other things. You can confidently purchase concrete floor grinders with the help of this article.

Planetary vs. Rotative: Which Is Better For You?

Choose between a rotative and a planetary machine as one of your first considerations. Planetary and Rotative are phrases used to describe how the discs move to perform their function. Every configuration has the capacity to execute a floor polish or grind to its own standards.

Planetary Grinders

Three smaller discs are stacked atop one main disc in a planetary grinder. The main disc, which can be compared to the sun, and the smaller planets or discs, which rotate on their own axes around the sun, provide a helpful analogy for planetary grinders (larger plates).

Since its only function is to rotate the smaller discs, the larger disc will never touch the ground. Compared to rotative machines, planetary concrete floor grinders are often lighter in weight, which might make it easier to handle and move around in some circumstances.

Concrete grinders can be gear- or belt-driven. Belt-driven planetary machine setups are frequently created.

Rotative Grinders

A rotary or rotative grinder can have more than one head since it rotates around a fixed axis. The width of the machine is the fundamental constraint of this type of grinder. While the 2 and 4-head configurations are the most popular, some rotative grinders have up to 8–10 heads.

A rotative grinder with many heads will almost certainly be a counter-rotating machine. It allows for easy operation by the operator and a straight path for the machine by the different heads, which rotate in opposite directions.

Planetary machines are lighter than planetary concrete blades for grinders, which are always gear-driven. They may therefore be a preferable option for removing heavy paint or adhesive.

Concrete Floor Grinder Power Options

There are several different power sources for a concrete grinder, including electric and gas. There are aspects of each of these choices that make them perfect for the kind of work you are performing.

Single-phase: The majority of residential homes use single-phase power circuits, which are two-wire AC power circuits. The best approach is a single phase if all your work is for residential clients. A single-phase machine’s key benefit is that it usually weighs less, is less expensive, and has more usable power.

Three-phase: A three-wire AC power circuit is known as a three-phase. The alternating current has a maximum voltage on each leg. It can become confusing, but you have more constant power that never decreases to zero to make it easier. They are big, strong machines that need a lot of power. Three-phase motors are more expensive, but they provide greater power.

You should make a few considerations before beginning to grind concrete or utilizing a concrete grinder. The products from U.S.SAWS are your finest option if you’re seeking the best concrete blade for grinder for both big and small projects. Always take your time when grinding the floor; rushing might lead to unevenness, which could be more balanced.
