Tumble Belt Blasting Machine, Automatic Sandblasting Machine

Automatic Tumble Belt Blast Machine

The tumble belt blasting machine is a type of automatic system that is suited for surface treatment of small and medium sized parts in batches, as well as relatively heavy, complex-shaped parts that would be hard to handle in a traditional blasting cabinet. 

The blast guns quanity can be tailored to the customers specifications to address all process constraints and for optimal results and productivity.

How does tumble belt sandblasting machine work?

Simply load parts on the rubber belt and set the timer, then return later to unload perfectly cleaned or finished parts. Parts tumble on a thick, perforated rubber belt, a group of blast guns uniformly blast medias to all exposed surfaces to deliver a consistent finish automatically. Nozzles are mounted on an oscillating blast gun to ensure maximum coverage of all parts.

Automatic Tumble Sandblasting Machine Features

Rubber Belt & Automatic Guns

1) Long life, wear-resistant rubber belt with a high loading capacity of 100kgs.

2) The endless rubber belt keeps parts gently tumbling as they are exposed to a group of oscillating blasting guns, which ensures abrasive flows cover all surfaces.

3) Each blasting gun is composed of boron carbide nozzles, which is the most durable material in the market.

4) The oscillating speed and amplitude can be adjusted for optimal finishing results.

Electric & Pneumatic

1) It is an easy system to control the working of each blast guns, as well as adjust belt tumbling speed, set blasting cycle time and start/stop dust collector at the side electric cabinet

2) The air pressure of each blast gun can be flexibly regulated by pressure valves at the front of the machine with clear gauges.

Sandblasting Dust Collector

1) Blast media is continuously separated from dust by a cyclone device, returning only pure blast media in good shape back to the blast nozzles for optimal results.

2) Configured a pulse filter cartridge for dust removal system, features high removal efficiency and requires easy installation and maintenance.

3) Closed cabin design with dust collector, always keeps your workshop clean.

4) Compact design and easy maintenance.

Tumble Belt Automatic Sandblasting Cabinet Applications

Tumble belt blasting machines are highly-efficient batch surface treatment equipment, which are best suited for small dimensional, regular-shaped metal workpieces that are not easily broken or tangled. These types of workpieces fully utilize the continuous, automatic, and batch processing advantages of the tumble sandblasting machines.

1. Small stamped parts, die-cast parts

Screws, nuts, bolts, washers, springs, small hardware, small automotive parts, electronic components, zinc/aluminum die-cast parts, etc.

Reasons: Small size, light weight, and able to tumble at the belt ensures that all surfaces are evenly blasted.

2. Regular-shaped parts that can tumble

Small or medium sized barrels, golf club heads, valve parts, gears, cutting tools (such as drill bits, milling cutters), etc.

Reason: The relatively regular shape, without deep holes or complex internal cavities, prevents them from jamming or snagging during tumbling, ensuring thorough sandblasting without blind spots.

3. Parts requiring removal of surface oxide scale, burrs, and rust

Heat-treated parts (oxide scale removal), machined parts (burr removal), forgings, and castings (rust removal).

Reason: Tumble sandblasting machines provide uniform impact force, efficiently cleaning these unwanted layers.
