WORKING PRINCIPLE OF HANGER TYPE SHOT BLASTING MACHINE
1) Two nos. 12½” size blast wheels are mounted on the sides of the hanger type shot blasting machine. Depending upon the requirement and size of the job blast wheels can be more in number.
2) During the blasting operation used shots falls into the longitudinal screw conveyor provided below the blast cabinet. From there the shots are transferred into the boot of bucket elevator. The screw conveyor is fitted at the bottom of the cabinet in a Hanger shot blasting machine.
3) The bucket elevator lifts the media and pours into the media separator where continuous screening is done to remove the debris from the blasted media. The screened media falls into the air wash type media separation system where the media is air washed to remove the dust particles from the usable shots and finally they are collected in a storage tank of suitable capacity for recycling to the blast wheel. The debris from media separator and unusable media from media separation system is collected in a bin [Buyer to arrange bin.
4) A suitable size of ducting is connected between blast cabinet to dust collector. The dust and fines from blast cabinet is sucked and is carried into the fabric bag dust collector. The dust particles gets collected in the hopper and clean air is discharged into the atmosphere, keeping the environment clean and healthy and that’s the advantage of not only a hanger type shot blasting machine but in all type of airless shot blasting machines.
With over 20 years of experience in designing and manufacturing hanger shot blasting machines, MAAN GLOBAL INDUSTRIES has become one of the best manufacturer of hanger shot blasting machines due to the trust that we’ve earned from some of the most renowned companies in India.

Height : 4200 mm from floor level
The cabinet in the direct blast zone is lined with 8-6 mm Mn steel liners rest cabinet is lined with 6mm Rubber sheet.
2) Blast Wheel Assembly: This is the most important part of the shot blast system that propels abrasive media on to the components at adjusted speed and direction. Blast wheel is the main part of the machine that fulfills the main function of the hanger shot blasting machine. There-fore correct adjustment and maintenance is very important. The blast wheel assembly is mounted on a 12 mm thick plate. It consists of two numbers blast wheels of size 12½” x 2½”. Each wheel consists of fabricated steel casing, alloy steel liners, rotor, blades, control cage and feed spout. The rotor is made out of EN grade material duly hardened to the full depth. The rotor is made out of EN grade material on CNC & VMC machines to the finest accuracy duly hardened. Each blast wheel is coupled through self lubricated and self aligning pedestal bearings. The rotor is dy-namically balanced and the drive shaft of the blast wheel is made out of EN grade material and duly precision grinded.
The machined parts of each wheel are prepared on VMC (5 Axis) & CNC machines to get higher accuracy and smooth fitment. As a leading manufacturer of Hanger shot blasting machine in India we ensure that changing of blades and other components dismantling is very easy to maintain.
Working Principle Of Blast Wheel Assembly :
- Steel shots go into the impeller from feed spout. Impeller and blades continuously rotates at high speed by means of motor, cage does not turn. Steel shots in the impeller come out of cage and drop onto rotating blade. Blade throws steel shots with high speed from the opening located at the bottom of wheel. In order to assure a good operation, impeller, cage and blades should be correctly adjusted; Abrasions occur on the parts that are in contact with abrasive media that distributes the directional flow of shots in a hanger shot blasting machine.
- Abrasive Circulation System The rotor of blast wheel assembly unit fires abrasive down on the perforated belt. The spent abrasive from perforated belt top falls into hopper of the cabinet. The abrasive from hopper slides down to the screw conveyors, which trans-fers them to the boot of the bucket elevator. These shots are elevated to the desired height with the help of buckets mounted on rubber belt. The tensioning arrangement for elevator belt is provided at the top portion of the elevator, hence no spillage of belt. We ensure that highest quality and performance is delivered as a leading hanger shot blasting machine manufacturer in India.
- A media separator is housed within the separator. Oversize contaminants and the media mixture are discharged from the head section of the bucket elevator into the media separator by means of an upper screw conveyor. The trashes will be directed by the internal screw flight to a trash and the air currents remove the contaminants. The dust and useless fines will be air borne to an expansion chamber from where coarse material will drop into a refuse hopper and thereafter to the floor level through dribble valve control. The fine dust particles will be conveyed through vent piping to the dust collector.
a. Screw Conveyor :
One no. screw conveyor is provided for blast cabinet. The trough is fabricated from 6 mm thick steel sheet and provided with perforated sheet to avoid any damage to screw conveyor and provision to remove the broken parts. Spent shot falls into the screw conveyor hopper, which transfers the media into the boot of bucket elevator. The screw conveyor shall be fabricated from ‘C’ class pipe, with 6 mm thick screw flight. The bearing used shall be of (NTN/SKF/FAG/ZKL) to take maximum load and to provide smooth operation. Bearing shall be sealed against dust and lubricated for more life. Drive for Screw Conveyor : Attached with Bucket Elevator Boot
b. Bucket Elevator & Media Separator :
The abrasive conveyed by the screw conveyor is elevated by the bucket elevator to the top where it enters the media separation unit. The media separation unit consist media separator which continuously segregate usable abrasive from blasted media and debris. The media separation unit is air wash type separation system receives media and dust after media separator.
The separation unit consists of baffles which generate a curtain of abrasive & dust and an air current is passing through the curtain which air washes the media thereby removing dust from the blasted media. Contaminants are removed by the separation unit for disposal by user [Buyer to arrange bin] and are discharged through chute.
Reusable abrasive falls into the storage hopper for re-circulation. The storage hopper is provided at the bottom of bucket elevator. The abrasive from storage hopper are transferred into the blast wheels through feed funnel. The flow of shots to the blast wheel unit is regulated by the dribble valve which is actuated by pneumatic cylinder in a spinner hanger shot blasting machine.
The bucket elevator is fabricated from 5 mm thick steel sheet at boot, Top section is 2.0 mm thk. and trunk section is 3.0 mm.
Drive for B. Elevator & Screw Conveyor : 1 HP, 415V/3P/50 Hz Geared Motor
4) Fabric Bag Type Dust Collector:
The fine dust laden air sucked from the cabinet enters into the dust collector. It passes through filter bags where the dust particles deposit on the surface of bags and clean air discharges into the atmosphere.
The fabric bag dust collector is constructed from 2 mm thick MS sheet and suitably reinforced for strength and rigidity. The fine dust is trapped on the surface of bags inside the dust collector. The cleaning of bags is achieved by mechanical shaking which operates for duration after the exhaust fan motor is switched off. The dust dislodged in the hopper
and from there it is transferred through the gravity operated flap valve to the dust bin
