Qingdao Zhiling Machinery Equipment Co., Ltd. shipped a Q6912 roller conveyor shot blasting machine to the Middle East in April 2026. The machine passed production testing and was subsequently packed and shipped to the Middle East. The client is a local steel structure processing company, primarily supplying steel for the construction and bridge industries.
Prior to the formal contract signing, the client visited the Zhiling factory and brought samples of steel plates and sections to be processed. After on-site testing, the client expressed satisfaction with the cleaning effect and subsequently signed a purchase contract.
Q: What types of workpieces does the client primarily process?
A: The client is a steel structure processing company located in the Middle East, whose main business is supplying steel for construction and bridge projects. The workpieces requiring cleaning include steel plates and sections, ranging in length from 6 to 12 meters. The workpieces developed oxide scale and localized rust during rolling and storage, requiring thorough cleaning before painting.
Q: What are the client's specific requirements for the equipment?
A: The client raised several specific requirements. First, the equipment must be able to handle workpieces up to 12 meters long. Second, the cleaned steel plate surface must meet the Sa2.5 cleanliness standard to ensure coating adhesion. Third, the equipment must have continuous operation capability to match the client's existing production line rhythm. Fourth, the equipment must comply with local environmental protection requirements, and dust emissions must be controlled within standard limits.
Q: How did the client learn about Zhiling Company?
A: The client learned about Zhiling through word-of-mouth recommendations within the industry. After comparing several equipment suppliers, the client added Zhiling to their shortlist and arranged a factory visit.
Q: What aspects did the client focus on during the factory visit?
A: The client mainly focused on several aspects. First, the factory's production capacity and management level, including workshop layout, processing equipment, and quality inspection processes. Second, the actual operating status of the Q6912 equipment; they inspected the same model of equipment being debugged. Third, the stability of the cleaning effect; they requested an on-site trial run.
Q: How was the trial run conducted?
A: The customer mailed a batch of steel plates and structural steel samples to the factory in advance. On the day of the trial run, technicians set the shot blasting machine speed and conveyor speed according to the workpiece dimensions and cleaning requirements provided by the customer. The sample workpieces entered the shot blasting chamber via the roller conveyor system, were shot-blasted, and then exited from the other end. The entire process was continuous, and the customer observed it on-site.
Q: What were the trial run results?
A: After the trial run, technicians and the customer jointly inspected the cleaning effect. The oxide scale and rust on the sample surface were completely removed, revealing a uniform metallic luster, and the surface roughness met the customer's coating process requirements. The customer expressed satisfaction with the cleaning effect, believing it met their quality expectations.
Q: What are the main technical parameters of the Q6912 roller conveyor shot blasting machine?
A: The Q6912 shot blasting machine is equipped with multiple high-efficiency shot blasters with adjustable blasting speed. The roller conveyor speed is frequency-controlled and can be adjusted according to the workpiece type and cleaning requirements. It is equipped with a cartridge dust collector, and the dust emission concentration meets environmental protection standards. Q: What types of workpieces is this equipment suitable for cleaning?
A: The Q6912 is mainly used for cleaning long steel materials such as steel plates, H-beams, I-beams, channel steel, and angle steel. It is also suitable for the external surface treatment of welded structural parts and steel pipes. The equipment uses a roller conveyor system, allowing workpieces to pass through the shot blasting chamber at a uniform speed, making it suitable for large-scale continuous production.
Q: What effects does the equipment achieve after cleaning?
A: After shot blasting, the oxide scale and rust on the workpiece surface are effectively removed, exposing a uniform metal substrate. Simultaneously, the blasting process creates a uniform micro-rough structure on the surface, providing a good adhesion base for subsequent coating. The equipment can consistently achieve the customer's required Sa2.5 cleanliness standard.
Q: How does the equipment's dust removal system ensure environmental compliance?
A: The equipment is equipped with a high-efficiency cartridge dust collector. The shot blasting chamber maintains a negative pressure state during operation, preventing dust from escaping. The dust collector uses a pulse-jet cleaning method, resulting in a long service life for the filter cartridges. The dust concentration at the emission outlet can be controlled within the range required by local environmental protection standards.
Q: What is the delivery time for the equipment?
A: From signing the contract to completing production commissioning, the cycle is approximately 35 working days. This includes stages such as drawing confirmation, material procurement, processing and assembly, no-load trial run, and load testing. After the customer confirms the trial run effect, the equipment is disassembled, packaged, and shipped.
Q: How long after the trial run does the customer decide to sign the contract?
A: After the trial run is completed, the customer expresses approval of the cleaning effect and the operational stability of the equipment. After internal evaluation and confirmation of commercial terms, both parties sign a purchase contract within one week.
Q: What other issues does the customer care about when signing the contract?
A: In addition to the equipment itself, the customer is also concerned about several aspects. First, the cooperation method for installation and commissioning. Zhiling will provide detailed installation drawings and remote guidance, and can send engineers to the site for assistance when necessary. Second, the supply of vulnerable parts. Zhiling has a stock of commonly used vulnerable parts and can ship them quickly. Third, operation training. After the equipment is delivered, systematic training will be provided to the customer's operators. Q: What are the follow-up arrangements after the equipment is shipped?
A: The equipment has been packed and shipped according to customer requirements. Installation drawings, operation manuals, and a list of vulnerable parts are included with the shipment. After the equipment arrives at the customer's site, Zhiling will provide remote installation guidance. After the equipment is commissioned, operation training will be arranged to ensure the customer can operate and maintain it independently.
Q: What industries are suitable for the Q6912 shot blasting machine?
A: This equipment is widely used in steel structure processing, bridge manufacturing, shipbuilding and repair, and petrochemical pipeline pretreatment industries. Any manufacturing enterprise with batch rust removal and surface pretreatment needs for steel plates, profiles, and welded structural components can consider this type of equipment.
Q: What are the main components of the equipment's operating costs?
A: Operating costs mainly include electricity costs, abrasive consumption, replacement of vulnerable parts, and routine maintenance. Electricity costs depend on the shot blaster's power and operating time. Abrasive consumption is related to the number of workpieces being cleaned and the processing intensity. Wear parts include shot blasting blades, directional sleeves, and wear-resistant plates; the replacement cycle depends on the frequency of use.
Q: What conditions are required for equipment installation?
A: The Q6912 is a roller conveyor type equipment. A pit needs to be reserved for the roller conveyor system and shot recovery device during installation. The height and length of the plant must meet the overall layout requirements of the equipment. Zhiling will provide detailed installation drawings and foundation construction plans.
Q: What is the significance of this cooperation for Zhiling?
A: The successful shipment of this equipment to the Middle East is another step forward for Zhiling in expanding its overseas market. The customer's purchase decision after on-site inspection and trial operation demonstrates that Zhiling's product quality and service capabilities have been recognized by international customers.
Q: What advantages does Zhiling have in the shot blasting machine field?
