power transmission by belts and pulleys, straight blade, high wear-resisting protective plate inside
Some detailed feature of the blast wheel:
The double disk is made of special material and machined and thermal-treated after forging. It is machined with machining center, which can carry out the "coarse mill---precise mill---drill, reaming” at one go, guarantees the balance.
Performance simultaneously lowers the noise emission.
Specially made high chromium wear-resistant liner blades and protecting plate guarantees long life.
The initial acceleration of the abrasive gained inside the distributor rotating synchronously with the blast wheel guarantees the shockless transfer to the blades.
The replacement of the blades is convenient and smart.
The rolling bearings of the blast wheel is high speed ones, reliable and with life expectancy of 3 years.
To guarantee the safety, on the conjuncture of the lid and the hull of the blast wheel there is limit switch. During working, if the lid is opened, the PLC will immediately cut the power source.
Prompt mount and dismantling of the blades: Because the blades is inserted from the center of the impeller, and fastened, during the high-speed rotating, with the centrifugal force, so no fastening and clamping element is required. When dismantling the blades, only by lightly hitting the outer part of them, they can be detached. Dismantling 8 blades need only 5~10 minutes. Simultaneously, the wear conditions of distributor and control cage can be inspected.
