Blasting chamber system
a.6mm-10mm thickness steel plates well welded in one piece and a line of thick Mn 13 steel protective boards at exposed area to the blasting shots stream guarantee excellent wear resistance of the blasting machine. These protective boards are not bolted on but hung with a special way and easy to assemble and replace. 3-6 blast wheels are installed at both sides of the chamber to guarantee that the work pieces can be cleaned thoroughly.
b.Both sides of the blasting chamber are equipped with doors.
c.A unique special multi-layer sealing system is developed and installed. It combines with brush seals and rubber segments to make the machine sealing effect excellently when the hooks and cross bar are adapted to the sealing system and it prevents accidents of shot spillage.
Screw conveyor system
a.2 or more screw conveyor systems are installed at the bottom of the blasting chamber and driven by the gear motor of the bucket elevator. During working, the screw conveyor transits the shots to the bottom of the bucket elevator and the shots are lifted by the buckets to the upper part of the elevator and put into the shot separator.
b.1 or more screw conveyor system is installed at the top side of the bucket elevator to both push shots to the shots separator and separating partial dust and small broken shots through the roller filter.
Bucket elevator system
a.The dismountable elevator is is driven by 1 gear motor at the top of the elevator and built with steel plates by accurate soldering technique and It includes 2pcs high-quality wheel hubs, 1 elevator body, 1 high-performance and durable belt and several alloy buckets.
b.It collects and lifts the shots recycled by the screw conveyor onto the separator and storage cabinet.
c.An access port is designed on the elevator for easy maintenance and examination.
Separator system
a.The air-flow separator is used to separate good shots and broken shots and dust. It is built and soldered with steel plates and different chambers are designed inside to lead the air flow and multi-level steel plates are installed to adjust and balance the sliding shots flow amount.
b.The air comes in from the inlet. The shots & dust mixture is transported from the screw conveyor and go downward on a sliding steel board and get into the way of the air flow. Good
shots are heavy and not driven to move by the air flow but broken shots are much lighter to be lead to the other slide board that connected with a broken shot collector/bucket. Dust directly flows in the air flow direction and is taken to the air outlet to be dealt with by the dust collector.
c.Magnetic separator is available for powerful sand separating of sand-casted parts.
Semi-automatic flow valve
a.Fully sealed semi-automatic flow valves are designed and equipped with lockable examination window and 2 bearing to control the flow amount of the shots into the blast wheels
b.At the upper part of each flow valve, a manual stop valve is installed to stop the shots flow under the circumstance of examination or maintenance.
Casting & CNC machined blast wheel system
a.Mayflay specially-designed casting & CNC machined blast wheels, combination of our own industrial advantages and features, ensure excellent performance of dynamic balance and perfect shots output efficiency and great convenience for maintenance. It is combined with a highly hard-wearing impeller, 8pcs extremely hard and durable plug-pull type blades, a control cage and a shot distributor to control the blasting direction and pre-accelerate.
b.Mayflay P series power system is used in this blast wheel: specially-designed and manufactured ABB motor, die steel CNC machined + low-pressure & vacuum heat treatment vulnerable parts inside. These special vulnerable parts have 58-62HRC surface hardness that is extremely durable and has super long lifespan. The most outstanding feature is the no-load current is only 6 Amps.
c.Variable frequency speed control technology to control and adjust the power of the blasting.
Dust Collector System
a.It includes cyclone separator and the cartridge filter. The cyclone separator separates most of heavy dust and the cartridge filter blocks and filters the escaped air & dust mixture.
b.Electromagnetic pulse technology is applied in the cartridge filter to shock and separate the dust from the filter. Dust goes down to the collect storage cabinet due to its gravity. Silencer and secondary filter ensure that noise emission is lower than 85DB and dust emission is lower than 50mg/m³
c.Wet dust collector is optional, a high performance dedusting system with Venturi theory, especially for flammable and explosive media, automatically recycle dust.
