Continuous Belt Shot Blasting Machine
Continuous Belt Type (Through Belt) Shot Blasting Machine: Core Advantages + Application Scenarios
Continuous Belt Shot Blasting Machine: The workpiece continuously feeds from one end, passes through the shot blasting chamber at a constant speed, and is continuously discharged from the other end. The feeding, shot blasting, and discharging processes are synchronized and uninterrupted, allowing for direct connection to an automated production line.
I. Core Advantages of the Continuous Belt Shot Blasting Machine
1. Continuous and uninterrupted production, significantly increased production capacity
No batch waiting, no need to close the door for unloading, capable of continuous operation 24 hours a day, with a processing capacity of 5–25 tons per hour, which is 40% higher than intermittent belt efficiency;
The belt speed can be adjusted by frequency, suitable for different cleaning difficulty workpieces, and the flow fluctuation can also stabilize the processing;
The feeding, shot blasting, and discharging processes are parallel, eliminating the downtime for loading and unloading, suitable for large-scale production line rhythms.
2. Highly automated, can be fully integrated
Can directly connect to casting molding lines, forging heat treatment lines, and stamping production lines. Castings are cooled and then automatically sent to the shot blasting machine, the entire process is unmanned transportation and no intermediate storage area;
Equipped with vibration feeding, magnetic sand separation, and automatic discharge conveyor belts, only one person is needed for inspection, significantly reducing labor costs;
Can be connected to PLC production control center, linked with the previous and subsequent processes, achieving full-process digital control.
3. Uniform and stable cleaning quality, good consistency
The workpiece passes through multiple sets of staggered-mounted shot blasting devices at a constant speed, providing full coverage of the upper, lower, and side surfaces with shot;
The belt slowly moves the material, causing slight flipping, without dead corners, and the roughness and rust removal grade of the same batch of workpieces are uniform;
Shot sand separation + multi-stage dust collection system, the broken shot, sand impurities are separated in real time, the shot purity is stable, and the cleaning effect does not deteriorate.
4. Compact in size, more flexible workshop layout
Straight-through structure, no need to reserve loading and unloading buffer zones, under the same production capacity, the floor area is much smaller than intermittent belt and hook-type shot blasting machines;
The loading and unloading ports can be connected to the front and rear conveying lines, arranged in a longitudinal series, saving workshop storage and transportation space.
5. Environmentally friendly and safe, excellent working environment
Fully enclosed chamber + pulse bag dust collection, dust is discharged in compliance with standards, no open-air sand blasting pollution;
Full automation, workers are away from the high-speed shot blasting operation area, reducing the risk of injury and dust-related occupational diseases;
Built-in sand material recycling device, casting sand, core sand can be recycled and reused, reducing solid waste emissions.
6. Lower overall operating costs
Significant reduction in labor, transportation, and storage costs;
High shot blasting cycle utilization rate, lower loss;
Continuous stable operation reduces frequent start-stop losses of equipment, longer machine lifespan, fewer fault shutdowns.
7. Stronger material compatibility
Two types of belts are available: rubber / metal;
Rubber belt: Small-sized castings, aluminum parts, standard parts, with slight impact;
Metal belt: High-temperature castings, heavy forgings, riser and runner materials for re-furnishing, resistant to high temperatures and wear.
II. Application Scenarios of the Continuous Belt Shot Blasting Machine
Suitable for small-sized, not afraid of slight impact, and large-batch metal workpieces, with a single-piece weight generally ≤ 65kg:
Cast steel / cast iron parts: Valve housings, motor housings, pump bodies, agricultural machinery small parts, casting risers and runner materials for re-furnishing;
Forging / heat treatment parts: Gears, connecting rods, springs, leaf springs, crankshafts blanks, various stamping and forging small parts;
Hardware standard parts: Screws, nuts, bearing blanks, motorcycle / electric vehicle components;
Non-ferrous metals: Aluminum die-cast parts, zinc alloy parts (select soft rubber belt to prevent scratching);
General hardware stamping parts: Stamping brackets, chassis small parts, welding small parts, rust removal and rust removal of welding slag.
Not applicable: Thin-walled easily deformed parts, precision polishing parts, slender easily tangled parts, large heavy single-piece.
III. Typical Industry Application Scenarios of the Continuous Belt Shot Blasting Machine
1. Automated molding production line in foundries (the most mainstream scenario) After the sand casting process is completed, the castings are directly sent into the continuous conveyor belt for the removal of surface sand, oxide scale, and gate burrs all at once. The sand can also be recycled simultaneously, achieving a complete integration of molding, cooling, sand removal, and shot blasting, replacing multiple intermittent conveyor belts and suitable for mass production lines of automotive castings and small components of construction machinery.
2. Batch production line for automotive components
Chassis small parts: connecting rods, balance blocks, gear blanks, brake components;
After heat treatment, the oxide scale is uniformly removed to enhance the adhesion of electroplating and spraying;
Automotive parts production line operates 24 hours continuously, matching the production rhythm of stamping and heat treatment.
3. Standard fasteners, spring manufacturing industry
Large quantities of rust removal and removal of rolled oxide scale for screws, springs, and gaskets, uniform surface roughness, enhancing the adhesion of electroplating / blackening; replacing roller shot blasting, with less workpiece impact and higher production capacity.
4. Valve, water pump, general machinery parts factory
Batch cleaning of small-sized cast iron / cast steel valve bodies and impellers, removing casting sand to ensure the subsequent machining accuracy; used independently by a single machine or connected to the pre-processing line of machining.
5. Forging heat treatment supporting workshop
Continuous removal of high-temperature oxide scale after quenching and tempering of forgings and die forgings, replacing the acid washing process, environmentally friendly without acid and alkali wastewater; suitable for mass production lines of agricultural machinery and hardware forging.
6. Recycled castings / re-forging material processing
Batch shot blasting and sand removal of risers and scrap castings, improving the purity of re-forging, suitable for automated recycling lines of casting waste.
