The application of slag grinding calls for a heavy duty type of machinery. Slag is usually on thicker parts that are cut by plasma or laser. This thermal slag is very tough to remove and with only one abrasive belt. Steelmaster utilizes multiple heads to remove the slag and possible secondary burr. It is even possible to get a rounded edge on these parts.
The typical slag grinder consists of four heads with abrasive belts and top- or barrel brushes. Depending on the contours and the warp of the parts, either barrel or top-brushes are advised.
The first step of getting rid of slag is cutting down the primary burr with two abrasive belts . The second belt is driven by a large diameter soft rubber contact drum to follow and adjust itself to the contours and warps of the parts.
Possible secondary burrs are removed with either barrel or top brushes. These types of brushes are easily exchangeable to configurate a machine for a spectrum of parts.
Steelmaster has two models that are specially configured for slag grinding.
These models are:
SMD RRTT Slag grinder with top brushes
This model has the advantage that it can co smaller parts and thinner parts than the RRBB. The top brushes follow all the contours of the part resulting in a constant quality.
SMD RRBB Slag grinder with barrel brushes
With the barrel brushes it is possible to get a nice round edge on the parts. The barrel brushes have the limitation that the can only be used with heavier or larger parts.
Below are two pictures illustrating the SMD RRTT The picture on the right shows the difference between the small hard contact drum and the larger softer contact drum.
