Plate Surface Pretreatment Shot Blasting Machine
- 产品详情
The KEEJOO brand plate surface pretreatment shot blasting machine is a roller conveyor-type continuous shot blasting system designed for flat or elongated metal components—such as steel plates and structural steel—and is utilized for surface pretreatment prior to processes such as painting, spraying, or bonding. Its primary objective is to remove mill scale, rust, weld slag, and contaminants, thereby achieving a uniform surface roughness (anchor pattern) that provides a reliable substrate for subsequent coatings.
Working Principle
A variable-speed roller conveyor continuously feeds the metal plates into an enclosed chamber of the shot blasting machine. Multiple high-speed blast wheels densely project streams of shot from various angles, powerfully impacting the plate
surfaces to achieve descaling. After the spent abrasive is cleared by a blow-off device, the mixture of shot and dust is collected by a screw conveyor and transported via a bucket elevator to a separator; the cleaned shot is then recycled for reuse, while the dust is channeled into a dust collection system to ensure emissions meet regulatory standards.

1. Efficient Continuous Pretreatment
Operating automatically via a roller conveyor system, the equipment conveys workpieces at a uniform speed while simultaneously performing shot blasting, cleaning, and dust removal. This design is ideal for high-volume continuous production, significantly boosting throughput.
2. Powerful Rust and Scale Removal
Utilizing a combination of high-efficiency blast wheels, the steel plates are subjected to a dense and uniform impact of shot media, thoroughly removing rust, mill scale, weld slag, and impurities. This results in a uniform surface roughness that meets the standards for pre-painting surface treatment.
3. Wide Range of Applicable Sheet Materials
Capable of processing a wide variety of plate specifications—including ship plates, structural steel plates, container plates, engineering machinery plates, and general metal sheets—this versatile machine offers exceptional adaptability in terms of both thickness and width.
4. Stable and durable, with worry-free operation and maintenance.
The wear-resistant guard plate structure, high-strength blast wheel, and sealed body design reduce wear and dust overflow, ensuring stable operation, long service life, and lower maintenance costs.
5. Environmentally friendly, intelligent, safe and reliable
Equipped with a dust removal system, it purifies dust generated during shot blasting and improves the working environment. The electrical control system is easy to operate, enabling automatic feeding, speed adjustment, and fault alarming, ensuring both safety and efficiency.
