  • What is the difference of the sand blasting machine and shot blasting machine?
  • Why is spinner hanger type shot blaster so excellent?


    The spinner hanger type shot blaster is almost an all-around machine for many types of work pieces surface treatment.

    It is compact in design, does not require a pit(generally), and consists of units featuring single hook, double hooks, lifting and non-lifting style designed to blast/peen castings, structural components, non-ferrous alloy parts. Hanger type machines are the most flexible machine types, one batch of parts move in, starts rotating, gets blasted and moves out, are used for demanding and decoring of pieces susceptible to breakage or impact damage and also for descaling and reconditioning in the metalworking industry. This kind of machine includes a wide range of facilities whose main characteristic is the great variety of part sizes and loading configurations that are available.

    Treated objects are hanged individually or in a cluster on the revolving hook and transported to the shot blasting machine via I, Y or circular closed loop conveyor. Revolving of treated objects in a jet of abrasive provides efficient treatment of the parts surface.

    Spinner hanger shot blasting machine is typically designed to handle mixed loads of medium and large components, which often include fragile and sensitive parts that cannot be tumbled in bulk loads. Mayflay Spinner hanger shot blasting machines are ideal for heavy and complex shaped workpieces. Parts can weight from 1 kg to 3,000 kg or more, manufactured in smaller and medium series.

    The Mayflay spinner hanger shot blasting machines are highly flexible systems that can be applied in many applications such as de-scaling, de-sanding, rust removal, paint stripping all fields of surface blast cleaning in the fields of steel structure, tank product parts, perforated parts, vehicle stabilizer bar, gear parts, transmission shaft, gear ring, forgings and castings etc.

    It has its core advantages that make it excellent:

    1.    Blasting sealing: Special seals in the ceiling prevent blast materials spillage and reduce the noise level around the machine. A unique special multi-layer sealing system is developed and installed. It combines with brush seals and rubber segments to keep the machine nearly 100% tight when the hooks and cross bar are adapted to the sealing system and it prevents accidents of shot spillage.

    2.    Blasting machine body: 6mm thickness Manganese 13 steel plates welled welded in one piece and Manganese 13 steel protective boards, offering excellent wear resistance.

    3.    The basic separator is air-flow separator. 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 exit to be dealt with by the dust collector. Multi-level plates are installed to adjust and balance the sliding shot flow amount. Good shots are collected by the shots storage cabinet for recycling usage.

    4.    Magnetic separator is available for powerful sand separating.

    5.    Semi-automatic flow valves: control the flow amount of the shots into the blast wheels with manual operation of adjusting the shots flow.

    6.    Our quality-guaranteed casted blasting wheel or even higher level all-CNC-machined blasting wheel provides excellent blasting result in very short cycle time.

    7.    Ultimately compact and smart design and small floor space occupation.

    8.    Programmable Logic Control. Safe operation, easy maintenance.

    9.    Maintenance and examination windows: windows are set on each maintenance position for easy maintenance.

    10. Machine invisible appearance: all our machines are dealt with surface treatment with our shot blasting machine before they are painted. With our shot blasting machine treatment, the machine surface is excellent for painting. We use high-end vehicle oil paint for our machine to have high level of painting quality and you don’t need to worry about broken painting problem under extremely nasty working environment.


  • What is sand blasting machine?

    The blasting machine is a machine that uses compressed air as a power to form a high-speed jet beam to spray to the surface of the workpiece.The surface needs to be treated to improve the mechanical properties of the outer surface. Besides, the surface of the workpiece is given a certain degree of cleanliness and different roughness, thereby improving the fatigue resistance of the workpiece, prolongs the durability of the coating film, and also facilitates the leveling and decoration of the coating, removes impurities, mottling and oxide layers on the surface, and at the same time roughens the surface of the medium to cause residual stress on the surface of the substrate, and the effect of increasing the surface hardness of the substrate.

     

    Unlike other sand treatment equipment, the sand blasting machine can use abrasive materials to be sprayed onto the surface of the workpiece by power from compressed air. The sand blasting machine is suitable for cleaning the rough surface of forged castings, stamping parts and machined parts, for spraying, pre-treatment steps before plating, and strengthening the surface of polished parts. The sand blasting machine is especially suitable for small parts are produced in small batches.

     

    The applications of the sand blasting machine:

     

    1.Pretreatment: electroplating, painting, spraying, etc. all covered by sandblasting before processing, the surface is absolutely clean, and greatly improve the adhesion of the cover layer and corrosion resistance.

     

    2.Cleaning: metal parts such as castings, stampings, welded parts, heat-treated parts, descaling, residue, dirt; surface cleaning of non-metallic products, black spots on the surface of ceramic blanks and reduction of lacquer patterns.

     

    3.Renovation of old parts: refurbishment and cleaning of all moving parts such as automobiles, motorcycles and electromechanical equipment. At the same time eliminate fatigue stress and extend service life.

     

    4.The light decoration: all metal products and non-metal products surface marks are eliminated, matte matte treatment, so that the surface of the product is upgraded.

     

    5.Mold treatment: matte matte treatment on the surface of the mold, graphic production, and mold cleaning, without damaging the mold surface to ensure mold accuracy.

     

    6.Burr treatment: the micro-burr removal of the machined parts, the plastic parts of the injection parts are eliminated.

     

    7.Rework of defective products: removal of bad cover of the product, poor surface coloring and removal of printing.

     

    8.Strengthening: increase the surface hardness of metal parts, eliminate stress, such as aircraft blades, springs, machining tools and weapons and other surface treatment.

     

    9.Etching anti-skid processing: metal products, non-metal products surface etching patterns, text and anti-slip treatment, such as: marble, handle slip, seal, stone lettering.

  • Which shot blaster is the best for small castings, forgings & small aluminum alloys?

    The answer is: Mayflay unique tumble belt shot blasting machine. 

    It works perfectly in all fields of surface cleaning, rust removal, oxidation layer removal and surface strengthening for small forgings, castings, stamping parts, gears, springs etc., especially for work pieces that are suitable for tumbling with each other.

    (图1)

    Why is this shot blaster born for a compact solution of small castings & forgings and other small work pieces that are suitable for tumbling?

    Mayflay tumble belt shot blasting machine is a design of roller style with rubber belt or steel belt. Ultimately compact with smart design and small floor space occupation. Economic style solution with powerful capacity of cleaning thoroughly every side of work pieces that are suitable for tumbling. It is an ideal option for blasting and cleaning work pieces in batches to have optimum blasting results on small delicate metallic parts, heavy castings, partially covered with sand or scale. Work pieces are loaded into the blasting chamber manually or automatically with loading & unloading system. In the process of blasting, work pieces are continuously cascading and tumbling over each other, resulting in all-around blasting coverage with high efficiency. Work pieces touch and contact each other during the tumbling make it even easier for blasting process.

    Automatic loading and unloading system makes Mayflay tumble belt shot blasting machine a typical & optimized choice to have reliable quality, extremely long lifespan, high efficiency of blasting and save cost of labor.
