M3040 Drive Heavy Duty Grinding Wheel Machine, Dual Station High-Speed Polisher, Casting Grinding Machine

The explosion-proof grinding wheel machine includes protective covers and other components, with the protective cover consisting of circumferential members and side members. Its characteristics are: protective devices are installed on the protective cover, which include adjustable barriers and a barrier position adjusting mechanism. The adjustable barrier's leading edge can be positioned tangentially close to or nearly tangential to the grinding wheel's rotating direction. The barrier, along with other parts of the protective cover, forms an almost closed barrier around the grinding wheel. During operation, the barrier position adjusting mechanism can make corresponding adjustments to the barrier position based on the wear condition of the grinding wheel to maintain the relative position of the barrier and the grinding wheel; the aforementioned tangential refers to: the effective working surface of the adjustable barrier being tangent to the outer circumference of the grinding wheel; the aforementioned nearly tangential refers to: being close to the outer circumference of the grinding wheel but nearly tangent, or the effective working surface of the adjustable barrier intersects with the outer circumference of the grinding wheel, with the corresponding central angle of the grinding wheel's outer circumference to the intersection chord.Alpha angle is less than 110 degrees; the proximity mentioned refers to: the distance between the two is less than one-seventh of the nominal diameter of the grinding wheel. The explosion-proof grinding wheel machine employs a double-layer protection device, which automatically opens the inner protective shield when the grinding wheel explodes unexpectedly or experiences significant vibration, to block the flying fragments of the grinding wheel and simultaneously cut off the power supply.
