Q3110 Drum Type Shot Blasting Machine

Q3110 Drum Type Shot Blasting Machine

I. Application
The high-speed impeller throws the abrasive to the continuous tumbling castings or forgings in barrel, to remove the greensand or scales on the surface. It cleans evenly and its productivity is high, so it is suitable for cleaning the small work pieces whose weight are under 15g in medium or small-scale casting or forging workshops.
As the machine has individual dust-collecting device, the installation spot is not limited by the ventilation pipelines in workshops. The cleaning condition is fine. The machine is equipped with auto-stop device, so it is convenient to operate.  
II. Work process
Put the cleaning work piece into the barrel and close the end-cover, and then adjust the cleaning time. First, move the semi-nut needle to the desired position, and then start the machine in turn.
After the barrel rotating, the helical ribs on the protecting board tumble the castings continuously, to make each surface cleaned evenly. Through the hole, the abrasive flows into the middle-wall, then through the screw belt conveying to the box-shaped frame, via elevator carrying to the top of the separator. Screen such big core-sand and burrs, etc, the small sand, dust and abrasive are carried away by the airflow. The integrity shot flows into the blast wheels for continuous usage.

Features:
Compact design, simple operating principle
Forced but gentle turning and tumbling of the parts for all-round shot impingement
Targeted high performance shot blasting for specific applications
Continuous and thorough shot removal

Applications:
Descaling of forged or heat treated parts
Desanding of ferrous and non-ferrous metal castings
Deburring of metallic and non-metallic parts
Deflashing of die cast parts
Contaminant removal
The tumbling action of the belt conveyor ensures that components are continually exposed to the blast stream and completely cleaned. For easy unloading, the belt conveyor is reversed, delivering the components into the loading skip or stillage.

Optimized shot blast effect:
During shot blasting, the workpieces, regardless of size and shape, are evenly and continuously tumbled. This is necessary for the effective and uniform treatment of all surfaces. 
During tumbling, the workpieces continually undergo shot removal, enabling workpiece interiors and cavities to be perfectly cleaned
For the complete removal of all shot, the final tumbling time that follows the shot blast sequence can be regulated to suit the type of workpieces being blast cleaned
The tightly sealed, leak-proof blast chamber minimizes shot consumption.
Advantage：

This machine is a new product developed by domestic and foreign technology. It is a kind of cleaning equipment with good cleaning effect, compact structure, low noise and good complete set. It has the following characteristics:

1. the machine uses a cantilever centrifugal blast wheel, with long service life, simple structure, etc.

2. using BE type separator, with good separation effect and high productivity, Leaf life has a positive effect.

3. The machine uses bag dust collector, and the dust emission concentration is lower than the national standard, which improves the working environment of workers.

4. Wear-resistant rubber belt is used to reduce collision and damage to the workpiece and reduce machine noise.

5. After the workpiece is cleaned, it can be automatically discharged, which reduces the labor intensity of workers.

Equipment Features:
This machine consists of blasting cabinet, flapdoor, blast wheel, material feeding device, elevator, separator, dust collector and electric control system.
Its working principle is: In cleaning up the room with a prescribed number of workpiece, after startup of the machine, the workpiece is drives the roller, began to flip, and shot blasting machine, high-speed thrown projectile formed pill beam, uniform blow in the workpiece surface, so as to achieve the purpose of cleaning, strengthening. Projectiles thrown and sand through the hole in the rubber crawler, into ascension machine, by the elevator to the separator to separate. Dust by fan ceiling sent for dust filter, clean air is discharged into the atmosphere, the bag dust by mechanical vibration play fall into the bottom of dust collector dust box, the user can be cleared on a regular basis, sand, waste by waste pipe out, users can reuse. Pill sand mixture by using tube retracted into the body chamber, separator are to be separated and reused, clean the projectile by electromagnetic for pill gate shot into the projectile hit the job.
