In the shot blasting process, uneven surface cleaning results—such as localized over-cleaning, residual mill scale, or significant variations in surface roughness—are common quality issues. These are typically caused by a combination of factors, including equipment condition, process parameters, and workpiece fixturing. The following is a systematic analysis based on engineering practice.

In industries such as steel structure fabrication, bridge manufacturing, and shipbuilding, surface cleaning of steel plates and structural steel is an essential step prior to coating. Efficiently and uniformly removing mill scale and rust from steel surfaces is a key concern for many production managers. Puhua Heavy Industry’s roller conveyor shot blasting machine is designed to meet this need; this article introduces the equipment by covering its working principle, applicable workpieces, technical features, and key selection criteria.

During operation, shot blasting machines generate a significant amount of dust; the dust collection system is a critical component for ensuring the equipment meets environmental standards and maintaining a clean workshop environment. However, in practical use, dust collection systems frequently encounter various issues. This article compiles the most common fault phenomena and troubleshooting methods for shot blasting machine dust collection systems, serving as a reference for equipment maintenance personnel.

Recently, a through-type shot blasting machine customized by our company for a domestic steel pipe manufacturing enterprise was successfully installed and commissioned at the customer's site and officially put into production. This equipment is mainly used for rust removal and oxide scale removal on the exterior walls of steel pipes. After commissioning, the customer reported excellent cleaning results and a significant increase in production efficiency.

Hook-type shot blasting machines are a common type of surface treatment equipment, widely used in industries such as automobile manufacturing, construction machinery, and casting and forging. This article introduces the machine from aspects such as working principle, equipment structure, applicable workpieces, technical parameters, selection points, and maintenance.

In the field of surface treatment, shot blasting machines are among the most widely used equipment. However, many users are confused when selecting a machine due to the variety of types, such as crawler, hook, roller, and mesh belt machines. Choosing the wrong machine not only affects production efficiency but may also damage the workpiece. This article provides a systematic selection approach from three dimensions: workpiece characteristics, production needs, and equipment features.
