Rubber Belt Conveyor Blast Cleaning Machine

The LuHuan LH-BB blast cleaning machine offers favorable, convincing solutions for blast cleaning of small and medium size workpieces, in batch quantities. The LH-BB series will accommodate batch weights of 180 kg to 1360 kg. The applications of these machines are especially variable:
1. Blast cleaning of iron castings, precision castings, and die castings
2. Descaling of forgings or heat-treated workpieces
3. Shot peening for surface compaction
4. Deburring of metallic (e. G. Stampings) and non-metallic workpieces
5. Surface finishing

LH-BB blast cleaning machines have been successful over several years and in thousands of applications, often in multishift operation. The LH-BBseries have proved to be economical for low production runs, as well, assuring reliable performance and optimum blast cleaning.
The LH-BB series offers the following advantages:
1. Attrative price/value ratio
2. Rugged, compact design
3. High blast cleaning performance
4. Quick and easy replacement of wear parts

Design and sequence of operations
Depending on the weight, size, volume, and flow rate of the castings to be cleaned, the machine can be loaded in a manual, mechanical, or automatic mode. The workpieces are then tumbled inside the blast cleaning chamber consisting of a continuous troughing rubber belt conveyor and lateral discs of highly wear-resistant material.
Especially designed carrier bars attached to the rubber belt conveyor assure gentle tumbling and full exposure of all surfaces of the workpieces. The abrasive containing burrs, scale, or sand drops through the perforations of the rubber belt and is then transported to the bucket elevator and the separator. After passing through the separator for removal of impurities, the abrasive returns to the storage hopper.

Hydraulic loaders are used for the machine types LH-BB170, LH-BB 340 and LH-BB 680 and, on special request, can also be provided for the smallest machine size LH-BB 85. The shot blast machines can receive the parts to be cleaned directly or using separate transport bins of the standard sizes 800*600mm or 1200*800mm. Other dimensions of transport bins can be accomodated.

Technical Specifications
1. Rugged welded structure fixed to the machine and to the floor
2. Separate hydraulic unit
3. Lifting movement of the tilting loader in two stages (one axis for lift and one for tilt) by means of lateral cylinders
4. Delivery of the transport bins to the front or to the side of the tilting loader
Other types of loading equipment (such as belt conveyors, etc. ) upon request.

LuHuan blast wheels are renowned for high capacity and maximum energy efficiency. These blast wheels come in various power ratings, giving a high degree of flexibility.
with modifications it is possible to reverse the blast wheel rotation thus allowing a greater range of applications. The amount of abrasive can be adjusted from the operator's panel. The abrasive is mechanically pre-accelerated and delivered to the blast wheel in a continuous stream. This ensures optimal utilization of the power from the drive motors. High wear-resistant material ensures maximum service life of the blast wheel. Unique design features allow for rapid and simple replacement of wear parts.
