Recently, a QT37 series circular track through-type shot blasting machine, customized for an Australian client, was successfully installed, commissioned, and officially put into production. The successful delivery of this equipment marks a further expansion of our company in the Australian market and provides strong support for the client's large-scale continuous production.
This client is a well-known steel structure manufacturing company in Australia, primarily engaged in the production of building steel structures, bridge components, and heavy machinery parts. Their products are widely used in local infrastructure construction and mining equipment manufacturing. With the continuous expansion of their business, the client has placed higher demands on the efficiency and quality of surface cleaning of their workpieces.
Before introducing a specific case, let's briefly explain the applicable workpiece range of the QT37 series circular track through-type shot blasting machine to help understand why the client chose this model.
The circular track through-type shot blasting machine uses a combination of a suspended conveyor chain and a circular track. Workpieces travel continuously on the track, receiving shot from multiple shot blasters at different angles as they pass through the shot blasting chamber. This continuous conveyor system makes it particularly suitable for the following types of workpieces:
**Large-batch production of small to medium-sized workpieces:** Such as automotive parts, standard parts, hardware, castings, and forgings. The circular track allows for continuous transport, suitable for large-scale continuous production, with efficiency far exceeding that of single-machine operations.
**Workpieces with regular shapes suitable for suspension:** Such as wheel hubs, brake discs, gears, flanges, and pipe fittings. Workpieces are suspended on the conveyor chain, and all surfaces are evenly impacted as they pass through the shot blasting chamber, resulting in consistent cleaning.
**Workpieces requiring continuous flow processing:** Suitable for direct connection with upstream and downstream processes (such as cleaning, painting, and drying) to form automated production lines.
**Bulk production of castings and forgings:** Such as small castings, forgings, and die castings. The circular track shot blasting machine can suspend a large number of workpieces at once, achieving high batch processing efficiency.
The client's existing equipment was a single-machine hook-type shot blasting machine, which presented the following problems in actual use:
**Efficiency Insufficient to Meet Capacity Needs** Hook-type shot blasting machines require manual loading and unloading and operate in single batches, making continuous production impossible and becoming a bottleneck for the client's capacity improvement.
**Frequent Workpiece Loading and Unloading** In single-hook operation, waiting is required for each batch loading and unloading, resulting in long equipment downtime and high labor intensity for operators.
**Inconsistent Cleaning Results** Single-machine operation is greatly affected by operator skill, leading to variations in cleaning results between different batches.
The client desired new equipment that could achieve continuous and automated production, increasing capacity while ensuring consistent cleaning results.
Based on the client's workpiece characteristics and production needs, our technical team customized the QT37 series circular track through-type shot blasting machine, with the following main configuration:
**Circular Track Conveyor System** Utilizing a combination of a circular track and a suspended conveyor chain, workpieces continuously pass through the shot blasting chamber, enabling assembly line operation. The conveyor speed can be adjusted according to production capacity requirements, balancing cleaning effect and production efficiency.
**Multiple Shot Blasting Unit Layout** Multiple high-efficiency shot blasters are configured in different positions within the shot blasting chamber, projecting the workpiece from multiple angles to ensure uniform impact on all surfaces of various workpieces, achieving thorough cleaning without blind spots.
**Automatic Control System** The equipment is equipped with a PLC control system, allowing preset parameters such as conveyor speed and blasting time for continuous automatic operation. Operators only need to suspend and unload workpieces in the loading and unloading area.
**Intelligent Variable Frequency Control** The shot blasters use variable frequency speed regulation, allowing adjustment of blasting intensity according to workpiece type and cleaning requirements, ensuring cleaning effect while reducing energy consumption.
**High-Efficiency Dust Removal System** Equipped with a high-efficiency cartridge dust collector, the shot blasting chamber maintains a negative pressure state, ensuring dust emission concentrations meet local Australian environmental standards, resulting in a clean working environment.
After the equipment was put into operation, the customer's production efficiency significantly improved. Continuous conveying via the circular track enabled assembly line operation, significantly increasing production capacity compared to the previous equipment. Consistency in cleaning effect was guaranteed, and batch-to-batch variations were greatly reduced.
Operators reported that the hanging and unloading operation is simple and reduces labor intensity. Operators only need to continuously hang and retrieve parts in the loading and unloading area, without waiting for a single batch operation cycle.
The customer's production manager stated, "This QT37 circular track through-feed shot blasting machine helped us break through the bottleneck in the cleaning process and achieve continuous production. The equipment's operational stability and the consistency of cleaning results exceeded our expectations."
The QT37 series circular track through-feed shot blasting machine delivered this time, through its continuous circular track conveyor, multi-shot blaster layout, and PLC automatic control configuration, helped the customer upgrade from single-machine operation to a continuous production line, effectively improving capacity and the consistency of cleaning results.
This case also further verifies the advantages of the circular track through-feed shot blasting machine in the continuous cleaning of large batches of small and medium-sized workpieces. Our company will continue to monitor the equipment's operation and provide customers with timely technical support and after-sales guarantee.
A: The QT37 series circular track through-feed shot blasting machine is suitable for continuous cleaning of large batches of small to medium-sized workpieces, including automotive parts, standard parts, hardware parts, castings, forgings, wheel hubs, brake discs, gears, flanges, pipe fittings, etc. Workpieces are suspended on a conveyor chain and continuously pass through the shot blasting chamber, suitable for assembly line operations.
A: The hook-type shot blasting machine is a single-machine operation; the workpiece remains in the shot blasting chamber for cleaning, suitable for small to medium batch, multi-variety production. The circular track through-feed shot blasting machine is a continuous conveyor operation; the workpiece is cleaned while moving, suitable for large-scale continuous production, with higher efficiency.
A: Yes. The equipment is equipped with a variable frequency speed control system, and the conveyor speed can be adjusted according to the type of workpiece and cleaning requirements. Slower speeds result in more thorough cleaning, while faster speeds result in higher capacity; adjustments can be made flexibly according to actual needs.
A: After cleaning with the circular track through-feed shot blasting machine, the workpiece surface oxide scale and rust are completely removed, presenting a uniform metallic luster. The cleanliness level can reach Sa2.5 standard, providing a good adhesion base for subsequent coating.
