Q37 Hanger Type Shot Blasting Machine for Cleaning The Surface of Various Castings in Sand Casting

Q37 type shot blasting machine is hook type shot blasting equipment, with the following characteristics.
Adopt the cantilever (or direct link, i.e. motor directly embedded) centrifugal blast machine with large blast volume and high blast speed to improve the cleaning efficiency and obtain satisfactory cleaning quality.

When cleaning the workpiece, the hook lifts the workpiece into the blast room blast area, close the door, start the dust removal system, separator, hoist, screw conveyor, shot blasting machine and supply shot gate, etc., can be blast cleaning work, the workpiece can move back and forth while rotating, so as to thoroughly clean up the dead corner of the workpiece,cleaning is complete, lifting out of the cleaning room, unloading, on the pieces.
Simulated blast diagram and all drawings of the blast machine are drawn using computer-aided design (CAD), the selection and arrangement of the blast machine is more reasonable. Improve the utilization rate of the projectile and labor productivity, to ensure the cleaning effect and reduce the wear and tear on the chamber shield.The cleaning room adopts wear-resistant steel plate protection, and the dust removal method adopts bag dust removal, and the electric control system has manual and automatic operation.
No pit. Not only saves the construction time and cost of the pit foundation, but also solves the problem of rusting and caking of shot sand in the elevator due to water in the pit used by customers in southern China.
the series is divided into single hook type and double hook type, double hook type with Y-type track, shot blasting workpiece and loading and unloading workpiece can be carried out separately, use the double hook form, the hook has its own travel track, do not need to change track when working.


Hook-type shot blasting machine: Expert in surface treatment of castings and forgings - 100% coverage and industrial-grade solutions for intelligent dust removal
In the casting, forging and other industries, the surface treatment of multi-variety and small-batch workpieces often faces the pain points of many cleaning dead corners and low efficiency. The hook-type shot blasting machine has achieved a breakthrough progress of 99.8% single-time processing pass rate and 35% energy consumption reduction through 360° dead-angle shot blasting and intelligent projectile recovery system, becoming the preferred equipment for surface strengthening and cleaning of small and medium-sized castings and forgings (weight 50-2000kg). This article deeply analyzes the equipment technical parameters, process adaptation logic and 20+ industry application data, providing enterprises with a full-process guide from workpiece detection to process optimization.



1. Core technology breakthrough: 3D dynamic simulation and precise shot blasting control
The hook-type shot blasting machine reconstructs the surface treatment quality through shot blasting trajectory simulation and dual-mode dust removal system:
Intelligent shot blasting system (meets ISO 11124-3 standard):
3D shot flow field simulation:
Based on ANSYS Fluent software to simulate the shot incident angle (30-85° adjustable), the coverage rate is increased to 100%;
For shaft parts with a slenderness ratio of >8:1, a spiral blasting mode (speed 4-8rpm) is adopted, and the surface roughness is Ra2.5±0.3μm.
Multi-station collaborative operation:
Dual hooks alternate in and out (switching time <30 seconds), and the processing efficiency reaches 150 pieces/shift;
Special mode for thin-walled parts (thickness <3mm): the shot speed is reduced to 45m/s, and the deformation is <0.1mm.

2. Dust removal and purification system (in compliance with GB 16297-2023):
Second-stage dust removal configuration:
Pre-dust removal in the settling chamber (removes particles > 50μm, with an efficiency of 85%);
Pulse back-blowing bag dust removal (filtration accuracy 1μm, emission concentration <5mg/m³)
Typical project economic account (motor housing cleaning case)


3. Industry application scenarios and process adaptation solutions
Locomotive gearbox strengthening treatment:
Adopt steel shot (S550) + steel wire cut shot mixed abrasive (hardness HRC50-55);
Shot blasting intensity 0.25mmA, increasing fatigue life by 3 times (ISO 1143 standard).
Building steel structure weld cleaning:
Weld slag removal mode: shot speed 75m/s, coverage 100%;
Dust removal system air volume 12000m³/h, dust concentration real-time monitoring and linkage start and stop.
Precision processing of machine tool guide rails:
Special nylon abrasive (Mohs hardness 3.5), surface roughness Ra1.6;
Equipped with a visual inspection system (accuracy 0.01mm), automatically determine the cleaning effect

4. Enterprise selection needs to focus on evaluation:
Workpiece adaptability: Shaft parts with a slenderness ratio of >10:1 require customized special hangers;
Environmental protection requirements: Prioritize the secondary dust removal configuration with dust emission <5mg/m³;
Intelligence level: Equipment with automatic abrasive replenishment and fault diagnosis functions can reduce operation and maintenance costs by 30%
