RMBC, RMBD and SMB Tumble Belt Shot Blasting Machines – Efficient and Controlled Blasting for Small Parts
The RMBC, RMBD and SMB models are tumble belt shot blasting machines designed for efficient and controlled surface treatment of small parts and bulk materials. In these systems, workpieces are processed on a continuously moving belt, combining the strong mixing effect of a drum system with more controlled and gentle handling.
Tumble belt technology is especially suitable for applications where consistent results, high productivity, and reliable part handling are required.
How Does a Tumble Belt Machine Work?
In a tumble belt machine, parts are placed on a belt-type conveyor that forms a “pocket.” As the belt moves continuously, it causes the parts to:
- move
- mix
- tumble in a controlled manner
At the same time, the parts are exposed to blasting media from multiple directions.
This enables:
- uniform treatment of all surfaces
- efficient cleaning and finishing
- better part control compared to traditional drum machines
Continuous movement ensures consistent and repeatable results
Available Tumble Belt Models
RMBC – Batch-Type Tumble Belt Machine for Versatile Use
The RMBC is a batch-type tumble belt machine where parts are processed in a controlled and uniform manner within the belt system.
Features:
- rubber or steel belt depending on application
- efficient part mixing
- uniform surface treatment
Suitable for:
- small to medium-sized parts
- castings, forged parts, machined components
Suitable for both delicate and more robust parts depending on belt material
RMBD – Continuous Tumble Belt Machine for High-Volume Production
The RMBD is a continuous tumble belt machine where parts pass through the machine automatically without batch cycles.
Features:
- continuous through-feed operation
- automated part handling
- high productivity
Suitable for:
- large production volumes
- automated production lines
- complex parts
Continuous processing enables maximum throughput and efficiency
SMB – Compact and Gentle Solution for Small Parts
The SMB is a compact tumble belt machine designed specifically for small and delicate components.
Features:
- gentle processing
- compact design
- easy integration into production
Suitable for:
- small and lightweight parts
- precision components
- applications where part damage must be minimized
Ideal when both consistency and gentle handling are required
