Product Description

Disa tumble belt shot blasting machine adopts high-strength wear-resistant rubber or manganese steel to load workpieces. The abrasives are blasted onto the workpieces in the chamber body through the blades which are rotated in a high speed to achieve a purpose of cleaning. The shot blasting strengthening process of this series of machines can realize surface burnt-on sand of various metal castings, surface derusting of ferrous metal parts, abating of the surfaces and burrs of the stamping parts, surface treatment of forgings as well as removing of the spring surface scales and refining of surfaces.
Tumble belt shot blasting machine mainly comprises a blasting chamber, a blast wheel assembly, an elevator, a separator, an electrical system and the like.
Working principal: when a specified amount of workpieces are added in the blasting chamber and the machine is started, the shots which are blasted by the blast wheels form projectile beam and are evenly attacked on the surfaces of the workpieces to achieve the purpose of cleaning and strengthening. The blasted abrasives and grits flow into the elevator and elevated to the separator through the elevator for separation. The dust is pumped into the dust collector through the fan for filtering and the clean air is discharged into atmosphere. The dust in the bags is mechanically shaken and fallen into the dust collecting box at the bottom of the dust collector. Users can regularly remove the waste grits and the waste grits are discharged from the waste grit pipes and can be recycled. The shot grit mixtures are collected in the chamber body through the recycling pipes. When the mixtures are separated in the separator, the clean projectiles flow into the blast wheels to blast workpieces.
Disa tumble belt shot blasting machine is specialized in batch operations. The tumble belt shot blasting machine can be integrated into the existing workshop by adopting a suitable loading and unloading device to form a continuous working process. Batch tumble belt shot blasting machine is applicable for mass and tumbling workpieces. The batch weight is 150 kg to 2500 kg, even can reach 5000 kg. 

Disa tumble belt shot blasting machine is designed to minimize the height of loading and unloading of parts to reduce damages to the sensitive parts. The range of products comprise the whole series of models used for cleaning and decoring of castings, forgings or derusting. The workpieces are continuously rotated during sand/shot blasting. Disa has unique and professional technique and can develop customized solutions, including automatic loading/unloading of workpieces and removing of the residual abrasives on the parts.
Loading device
The workpieces are fed into the slot type shot blasting chamber. The shot blasting chamber comprises continuous rubber conveyor belts or steel plate conveyor and an adjustable horizontal disc. The speed of the conveyor belts can be adjusted according to the tumbling status of the workpieces in order to make a single workpiece stay for enough time during shot blasting process.
If the conveyor belts are operated in the opposite direction, the workpieces are unloaded to the container or unloaded to the conveyor belts from the tumble belt shot blasting machine. Manual, mechanical or automatic loading enables the tumble belt shot blasting machine to be integrated into the continuous production process.
Applications:
Desanding and decoring of iron, bronze and light metal castings
Descaling of forged metal parts, and heat treated components
Deburring of metallic and non-metallic parts
Forced but gentle turning and tumbling of the parts for all-round shot impingement
Targeted high performance shot blasting for specific applications
Continuous and thorough shot removal
