Sandblasting is a general term used to describe the act of propelling very fine bits of material at high-velocity to clean or etch a surface. Sand used to be the most commonly used material, but since the lung disease silicosis is caused by extended inhalation of the dust created by sand, other materials are now used in its place. Any small, relatively uniform particles will work, such as steel grit, copper slag, walnut shells, powdered abrasives, even bits of coconut shell. Due to the dangers of inhaling dust during the process, sandblasting is carefully controlled, using an alternate air supply, protective wear, and proper ventilation.

A sandblasting setup usually consists of three different parts: the abrasive itself, an air compressor, and a blaster nozzle. For etching and small object cleaning, a workstation to hold the piece of glass is also needed, as is some sort of collector to gather up excess dust. Sandblasting is primarily used for two somewhat different applications. The first of these is to clean a surface of anything that may be clinging to it. The second is to either etch or carve designs or words into glass or a similar material.
Shot blasting machine how to solve the common fault?
Shot blasting machine because it is easy to wear goods, daily use will be a variety of problems, the Mayflay Machinery (Huizhou)Co.,Ltd summary of the problems and their handling methods.
Cause Analysis and Measures of impeller head Bearing Failure:
Shot blasting machine in the production process of the main bearing failure are: the installation is not standardized, the lack of lubricants, fatigue wear, external damage. The corresponding measures: in strict accordance with the norms of installation and regular maintenance of bearings, filling lubricating oil, improve lubrication conditions. The original bearing body parts using high pressure gun to the oil way, 8 throwing the first time to fill the lubricating oil to be completed 3 hours to complete, neither safe nor a waste of time. Now use each of the bearing parts through the high-pressure steel wire hose connected by the high-pressure oil pump automatically refueling, 8 throwing the first time to lubricate oil only 10 minutes, safe and efficient. The choice of lubricating oil is appropriate will directly affect the life of the shot blasting machine and good machine, usually the bearing surface temperature is not easy to more than 60 °, the use of innovative sulfonated polymer 1615EN, the grease has a strong water resistance ; Corrosion resistance; high temperature (100 ° higher than ordinary lithium grease), long service life characteristics. Select the efficient axial fan to force the cooling, reduce the bearing ambient temperature; throwing body to increase the vent hole in order to automatically add lubricating oil. Regular maintenance of impeller, blades, guard and belts, etc., to eliminate the mechanical resonance generated by external forces.
Analysis of the Causes of Leaf Damage and Measures:
Shot blasting machine blades are thrown out of most of the projectile impact, so the blade is the most vulnerable parts of the blasting machine. Blade wear or cracking will make the impeller in the high-speed rotation when the vibration, check the blade appears deep groove or wear more than half of the time to be replaced. In addition, the blade casting defects will inevitably accelerate the wear of the blade, because there are casting defects in the leaves of the projectile in the course of the phenomenon of bounce, bounce the projectile in turn caused erosion of the leaves, aggravated blade wear. In order to ensure the stability of the operation of the shot blasting machine, the blade replacement must be carried out in pairs, that is, leaves corresponding to the undesirable blades must be replaced at the same time in order to obtain a good dynamic balance. If the blade of the shot blasting machine lead to the work is not normal, put all the leaves all replaced, there are casting defects of the leaves determined not to pay attention to the installation of leaves when a group of eight leaves the weight difference of not more than 5 grams.
Analysis of the causes of damage to the orientation sleeve and the measures taken:
Shot blasting machine set of fixed sets in the shot blasting machine shell, turn the steering sleeve can change the direction of throwing the projectile, when the directional sleeve inside the deep groove or directional sleeve nest was grinding about 10 mm should be replaced. Shot blasting machine directional nest and impeller center line offset angle determines the size of the projectile radial scattering angle, generally about 45 ° is appropriate.
Damage and replacement of the pellets:
The sub-ball wheel is fixed on the spindle and rotates together with the impeller. The sub-ball is a vulnerable part. When the sub-ball wheel wears more than 15 mm, it should be replaced in time. If it continues to use, the radial scattering angle of the projectile will increase the wear and tear Clean up the effect.
Impeller damage and replacement:
Shot blasting machine impeller through the eight bolts fixed on the combined disk, in order to ensure the stability of the operation, the impeller should be checked regularly with or without shaking, check the roundness and gravity of the wheel discs and found that serious wear and tear must be replaced, Wear will cause a greater shock damage to the blasting machine box and liner, the other impeller and the combination of disc surface is also prone to uneven vibration.
The inspection and replacement of the sealing material of the blasting machine:
Shot blasting machine and the side shield of the edge of the shield with a certain gap between, in order to ensure that the projectile is not spilled, shot blasting machine cover and the box has a rubber material seal, due to mechanical vibration Part of the projectile impact rubber pad often caused by a large number of gasket piercing overflow, there must be timely replacement of the gasket. Polyurethane plates are used instead of rubber sheets as gaskets. Polyurethane plate with high elasticity, strength, excellent wear resistance, oil resistance, a strong fatigue resistance and anti-vibration, the use of good results.
Inspection and replacement of end shield and side guards:
The end shield and side guards of the shot blasting machine are fixed on the inside of the shot blasting box to protect the shot blasting box. The end shield is connected by four trapezoidal bolts. If the trapezoidal bolt is deformed, it should be replaced promptly. The end shield wears cracks or obvious grooves and should be replaced in time. Side guards up and down the joint surface wear serious or crack, should be replaced; shot blasting machine side guards fastening bolts must be tightened in the outer groove, to prevent the side guards off.
Dust removal system problems and take measures:
Shot blasting machine with bag filter system. Shot blasting machine running process, the operator through the dust on the handle of the dust once a hour, each time shaking the handle more than 10 times. After the shot blasting machine stops running, the operator manually opens the bottom of the bag machine out of the gray mouth, remove the fouling. Bag dust collector in the course of the operation of the common faults and treatment methods are: dust from the shot room to escape 1) exhaust regulation due to vibration displacement caused by the lack of exhaust air volume, adjust the baffle; 2) dust filter bag dust 3) dust collector dust less than the internal fouling caused by insufficient air volume, should be timely; 4) dust removal equipment failure, should repair the equipment.
The dust collector is not dust or dust is not ideal:
1) dust collector fan wiring error, fan reversal, should be re-wiring;
2) dust bag inside the bag is not strong, damaged or lack of bags, should be adjusted;
3) Dust chamber or dust pipe seal is not strict, should ensure that the Department of sealing
4) Dust catcher and warrior mechanism is not enabled or enabled a small number of dust blocking bag, should be promptly cleaned attached to the dust on the bag.
Separator system problems and take measures:
The main role of the separator of the shot blasting machine is to separate dust, pellets and fine pellets. Separate air flow is too large or too small are not conducive to production. When the air volume is too large, it is easy to cause the separator in the waste pills containing coarse available pellets, when the air volume is likely to cause dust can not be properly discharged. When the air volume is too large, you should adjust the air volume control valve to reduce the amount of air supply. When the air volume is insufficient
(1) if the separation should be small particles, should check the separator, adjust the baffle to increase the separator air volume;
(2) the sliding slope of the separator position should be appropriate to adjust the ramp position to expand the air volume ;
(3) the total air volume of the precipitator is low, should adjust the total valve open air volume.
Shot blasting machine import and export problems and take measures：
According to the actual needs of the production, need to throw a certain number of floating plate, floating plate through the shot blasting machine can easily impact the front of the sealed room rubber curtain caused by the fabric screw plugged boring car production, is now used in the shot blasting machine entrance Before the design of a high limit device, when the floating plate hit the high limit device when the roller stop, the plate can not be room to throw. The steel plate after the shot on the surface of the rust is still left a projectile or dust, is now used in the shot blasting machine at the exit of the design of a free rise and fall with the thickness of the high-pressure hair dryer system, in time to sweep the steel surface of the projectile or dust, Surface treatment quality, played a good effect.

What’s The Difference Between Sand Blasting And Shot Blasting?
Both sand blasting and shot blasting are mechanical surface cleaning process. But the principle and application are different.
Sand blastingtakes compressed air as its power and shots the high speed abrasive sand stream to the surface of work piece. Due to the impacting and cutting effect of the abrasive sand, the work piece surface is completely cleaned, at the same time, the surface quality and mechanical performance is greatly improved. Processed work piece will have better fatigue resistance and adhesion force, which will help the coating have smooth level and last much longer.
Sand blasting machine application: All kinds of small and medium-sized castings forging hardware and other surface cleaning
Abrasive blasting machinefunction :surface the cleaning , deburring, To stick sand, Enhance the surface roughness
Shot blasting takes the centrifugal force of the high speed rotating disk to shot the steel shots to the work piece surface. After processing, the work piece will have finishing effect and generate pressure stress to improve fatigue strength. Compared with sand blasting, shot blasting do not generate silicon dust and have less pollution to the environment.
Shot blasting machinehave different type, application rage is very wind,such as small and medium-sized ,mold,forging,and casting,auto gear and shaft blasting reinforcement,gear shaft, stabilizer bar ,aluminium casting,irregular parts.
