What is Automatic Shot Blasting Machine with Hoist for Hot Rolled Bars Sa 2.5?

An Automatic Shot Blasting Machine with Hoist for Hot Rolled Bars Sa 2.5 is a specialized industrial device designed to clean and prepare the surfaces of hot-rolled bars to achieve a surface finish grade of Sa 2.5 according to ISO 8501 standards. This machine is particularly effective for removing rust, scale, and other contaminants from hot-rolled bars, ensuring they are ready for further processing such as painting or coating.

Key Features

l Hoist Conveyor System: The machine is equipped with a hoist conveyor system at both the inlet and outlet sides, allowing for efficient loading and unloading of hot-rolled bars.

l High-Efficiency Blast Wheels: It features high-speed blast wheels that propel abrasive media (such as steel shot) at the workpiece surface, effectively removing contaminants and achieving a surface finish grade of Sa 2.5.

l Abrasive Recycling System: The machine includes an abrasive circulation unit with a bucket elevator and a separation/cleaning system to recycle and clean the abrasive media, reducing waste and operational costs.

l Dust Collection System: An integrated dust collector with a cleaning mechanism ensures environmental compliance by capturing and filtering dust generated during the blasting process.

l PLC Control System: The machine is controlled by a PLC (Programmable Logic Controller) system, allowing for precise control over the blasting process, including conveyor speed and blast intensity.

Technical Specifications

l Workpiece Size: The machine can handle workpieces with dimensions up to W: 1300 mm × H: 1800 mm × L: 3000 mm.

l Loading Capacity: Maximum loading capacity is 5 tons.

l Blasting Speed: The blasting and pass speed can be adjusted between 0.5-2.5 m/min to achieve a surface finish grade of Sa 2.5.

l Surface Roughness: Achievable roughness of steel plate is Ra 25-65 µm (adjustable), depending on the diameter of the steel shot.

l Noise Level: ≤92 dB in the operating area.

l Dust Emission: Concentration of dust emission is ≤100 mg/m³.

l Total Power: 199 kW.

l Air Compressed Consumption: 1.2-1.5 m³/min with an air pressure of 0.5-0.7 MPa.

Applications

l Heavy Industry: Ideal for cleaning and preparing hot-rolled bars for further processing.

l Coating Preparation: Prepares the surface of hot-rolled bars for painting or coating by removing rust and scale.
