As we all know, the shot blasting machine is composed of many parts, such as a roller conveyor system, shot blasting system, abrasive reclaim system, dust collector, and others. Among them, the shot blasting system is the most important part of the machine. Now let QGMA introduce some points to explain how to choose different types of blads.
The importance of the blast turbines
The blast turbines are the core of the shot blasting machine, which has a great impact on the surface of the workpiece. The KT series of blast turbines, which Qinggong Machinery developed is distinguished by exceptional characteristics. It also has various component configurations and easy maintenance.
Types of the blades
The blades have two kinds of types. The one is the same as its name, straight blades. The other one is the curve. If viewed from the side, the blades have a certain angle.
Choice of the blades
Compared with the same size of the straight blades, the biggest advantage of the curved blades is the higher grinding speed. So the energy shock transferred to the workpiece is greater.
The curved blade can achieve abrasive exit speed, 27% to 30% higher than the straight blade. It is mainly used in the following situations:
- When more particle energy is required and distance is greater
- The workpiece with higher requirements for roughness
- Where scale needs to be removed
Under the same motor power, the straight blade can achieve a lower outlet speed but a higher mass flow rate. Therefore, the choice of the blade depends on the specific situation.
Replace the blades
If you first decide to use a straight blade and later find that you don’t get the right results and prefer to use a curved blade, this is not a problem because all parts are interchangeable. The KT series wheels can be fitted with straight or curved blades, as changing blade type and the material does not represent any additional cost or modification.
The KT series blast turbine has proven to be cost-effective and reliable as they are used by many customers in the foundry, metalworking, and automotive industries.
The KT series of high-performance turbines have spare parts for the shot blaster, including a shot blaster with eight projectile blades locked in the wheel twin discs. Double disc wheel has the following advantages:
Improved abrasive flow speeds up cleaning cycles
Directly mounted motors or spindles eliminate manual wheel positioning problems
The front of the housing provides easy access to the runner’s head
Optional replaceable, durable cast liner
Integrated dual labyrinth hub seals provide a superior abrasive seal
T-nut helps to replace the housing
Integrated U – shaped inlet fixture for improvement adjustment and assembly
Low speed and high-speed direct-drive motors
The directly-coupled spindle drive allows the reuse of existing motors
Fewer parts wear due to higher concentricity and more precise alignment
