Blasting chamber system
a.6mm-10mm thickness Manganese 13 steel plates, accurately welded in one piece, and a line of 10mm Manganese 13 steel protective boards, installed at the area exposed to blasting shots stream, guarantee excellent wear resistance of the blasting chamber.
b.4-16 sets of blast wheels, equipped vertically and horizontally at both sides of the chamber, guarantees thorough cleaning of every work piece.
Multi-layer rubber sealing technique is used at the inlet chamber and outlet chamber to protect the side steel plates. Rubber segments sealing method make the machine sealing effect excellently and prevents accidents of shot spillage.
Roller conveyor system
a.Stepless speed regulation system is used for the whole transporting system for the work pieces to have stable and reliable operation and optimized blasting result on work piece.
b.The roller conveyor system is combined with three segments: inlet roller conveyor, blasting chamber roller conveyor and outlet roller conveyor.
High loading weight makes the roller conveyor system sustainable to heavy work piece and workload.
Screw conveyor system
a.2 or more screw conveyor systems, installed at the bottom of the blasting chamber and driven by the gear motor of the bucket elevator, consist of screw axle, blades and screw heads at both sides.
b.During working, the screw conveyor pushes the collected shots to the bottom of the bucket elevator and the shots are lifted by the buckets to the upper part of the elevator and pour into the shot separator.
1 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 rolling mesh sieve.
Bucket elevator system
a.The elevator system is built with steel plates by accurate soldering technique and driven by 1 gear motor at the top.
b.It includes, 2pcs high-quality wheel hubs, 1 elevator body, 1 high-performance and durable belt and several alloy buckets, providing the maximum transporting amount 130Ton/H. It collects and lifts those shots that are recycled by the screw conveyor, onto the separator and storage cabinet.
c.A window is designed on the elevator for easy maintenance and examination.
Separator system
a. Air-flow separator is used to separate good shots and broken shots and dust. It is built andsoldered with steel plates and different chambers are designed inside to lead the air flow.
b.Mixture of shots & dust is transported from the screw conveyor (if equipped) and goes 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 to be connected with collector/bucket. Dust directly sucked and taken to the air outlet to the dust collector.
Multi-level steel plates are installed to adjust and balance the sliding shots flow amount. Good shots are collected by the shots storage cabinet for recycling usage.
Semi-automatic flow valve
a.Semi-automatic flow valves, fully sealed with lockable examination window, are equipped to control the flow amount of shots into the blast wheels.
On the top of each flow valve, in case steel shots flow from the storage silo, a manual stop valve can be switched off under the circumstance of examination, repairing and maintenance.
Blast wheel system
a.Thanks to German technology, Mayflay casting and fully CNC machined blast wheels are designed and manufactured with highly hard-wearing materials and steel plates for easy replacement and maintenance.
b.Designed and manufactured in combination of our own industrial advantages and features to have excellent performance of dynamic balance and perfect shots output efficiency.
c.Highly hard-wearing materials and steel plates are installed inside for easy replacement and maintenance, working with variable-frequency speed control technology to control and adjust the power of the blasting.
d.Mayflay P series power system (available), 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.
Abrasive Romoval Unit ( For Steel Plate )
a. After the blasting process, the workpiece may still be covered in blast media, which must be cleaned off. This task is carried out by a rotating brush, which is fitted with securely attached brush segments, which are interchangeable.
b. To avoid blast media building up on long parts, the rotation brushes flick the spent abrasive from the work surface into a specially designed trough which has a screw conveyor taking the media back into circulation. To keep the position between the brushes and the screw conveyor constant when blasting different sized work pieces, both are built with the same adjustable framework. manual bursh height adjustment by press button. Finally remaining media on the surface of work pieces will be removed by the blow off station, which is mounted on the same framework and uses high pressure ventilators to blow off any media remaining.
Dedusting System: cartridge filter with secondary filter system
a.A typical dedusting system for shot blasting machine: cyclone separator and the cartridge filter. the cyclone separator separates and collects 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.
c.The built-in filter needs regular cleaning and replacement to prevent the spillage of dust from inside because of the blocked and malfunctioned filter.
d.This dedusting system works with silencer and secondary filter to ensure that noise emission is lower than 85DB and dust emission is lower than 50mg/m³
Wet dust collector is available. High performance dedusting system, with Venturi theory, is a great dust separator especially for flammable and explosive media. Wet dust is automatically recycled and the electromagnetic water valve automatically open to provide new water when the water level in the water box is low.
