Continuous Tumble Pass-Through Shot Blast Machine
Product Introduction

Mayflay tumble belt blasting machines are ideal for blast cleaning workpieces in batches. Optimum blast results are achieved on small delicate metallic or plastic parts, too large, heavy castings, partially covered with sand or scale. During the shot blast process the workpieces are constantly cascading over each other resulting in effective all-around blast coverage.

Application

Tumble belt blast machines of Mayflay range are ideal for descaling, de-burring, desanding or core sand removal for all types of castings, forgings and heat-treated workpieces.

Outstanding Advantages
  • Using Wear-resistant rubber track+manganese plate;
  • Using advanced wet dust collector system;
  • Using crushed shot secondary separation system;
  • Using high performance P series impeller head (die steel CNC machining + vacuum heat treatment);
  • Using steel shot flow automatic control system;
  • Optional: automatic loading and unloading system;
  • Optional: Magnetic sorting system + spiral pusher sorting + air separation sorting system;

Technological Process
During the shot blast process the workpieces are constantly cascading over each other resulting in effective all-around blast coverage. The continuous contact between the workpieces accelerates the deburring process and/or the loosening and discharge of sand cores from sand castings. Up to three high-performance blast wheels guarantee homogeneous blasting results in extremely blasting cycle times, the endless belt can consist of high quality perforated rubber, or respectively, a hardened steel or manganese steel slat. Workpieces specific mixing strips. Either bonded on the rubber or welded on the slats ensure an optimized cascade action in combination with a selected belt speed.
Quality Control
1Shot blaster

1. The blasting machine motor adopts ABB with excellent and controllable manufacturing process, good sealing, good dynamic balance and stable and reliable performance advantages.

2. The blasting machine outside shell is made of 10mm high-quality carbon steel plate by laser cutting and precision bending. The shell is welded by special fixture to ensure the parallelism of the two sides of the blasting machine shell and the concentricty of the hole.

3. The top guard plate is precision machined by die steel CNC, and the machining precision is ±0.01. After machining, low pressure vacuum heat treatment is adopted.

4. End guard plate is made of high wear-resistant manganese 13 steel plate by laser cutting.

5. The side guard plate is precision machined by die steel CNC, and the machining precision is ±0.01. After machining, low pressure vacuum heat treatment is adopted.

6. The Orientation sleeve is precision machined by die steel CNC, and the machining precision is ±0.01, with uniform wear and good balance. After machining, low pressure vacuum heat treatment is adopted.

7. The Pill wheel is precision machined by die steel CNC, and the machining precision is ±0.01, with uniform wear and good balance. After machining, low pressure vacuum heat treatment is adopted.

8. The blades is precision machined by die steel CNC, and the machining precision is ±0.01, with uniform wear and good balance. After machining, low pressure vacuum heat treatment is adopted.

9. The impeller is precisely machined with CNC die steel, and the machined precision is (+0.01). The surface hardness of the impeller can reach HRC58-62 by vacuum heat treatment under low pressure after machined.

10. The service life of the above vulnerable parts is more than three times as long as that of the casting products (shot material: less than S460 (1.5mm cast steel shot), hardness: HRC40-50).

2Flow valve

1. Semi-automatic flow control system, used to control the flow of shot into the shot blaster, the flow of steel shot is adjusted manually.

2. Fully sealed structure design, with lockable inspection openings and two bearings.

3. The upper end of each flow valve is equipped with a manual globe valve. If the flow valve needs to be repaired, it can be closed so that close the steel shot flowing from the silo for easy maintenance.

3Shot blasting room

1. The shot blasting chamber is welded with all manganese steel.

2. Several manganese steel protective plates are installed in the hot zone of shot blasting chamber, which are located in 3/4 of the direct shooting area of the shot blaster. They are fixed by suspension, simple to install and easy to be disassembled and replaced.

3. A three-layer sealing structure is installed at the top to prevent the steel shot leaking from the top during shot blasting operation.

4Hydraulic automatic loading system


1.Hydraulic system is an independent integrated power transmission device, which converts mechanical energy or electric energy into driving part of rotary force, and then converts rotary force into pump part of fluid energy.

2. Hydraulic system consists of motor, pump, electromagnetic reversing valve, oil-controlled one-way valve, throttle globe valve, oil tank, etc.

3. Various actions can be realized through the on-off of the electromagnet (the two electromagnets of the solenoid commutation valve can not be charged at the same time). The speed of the regulating valve or the action of closing the actuator are adjusted respectively by adjusting the regulating valve.

4. The system uses 46# antiwear hydraulic oil. The optimum working temperature of the whole hydraulic system is 30-55 C.

5. Main technical parameters of hydraulic system: tank volume: 80L; motor driving power: 4Kw; rated pressure: 12MPa; rated flow: 14.7L/min.

5Automatic unloading system

1. A set of automatic blanking mechanism. The workpiece is reversed from the shot blasting chamber and falls into the automatic blanking mechanism. Then the parts are conveyed to the feeding frame by the vibration device.

2. The blanking mechanism is equipped with a fall-proof rubber cushion, which can effectively prevent the impact between the parts and the shock and play a very good protective role.

6Electrical control cabinet

1. Using Siemens PLC and touch screen

2. Using Delta or BEST converters

3. Use CHINT or Schneider brand low-voltage electrical components

4. Using shot blasting time controller

5. Using ADE aerodynamic components

6. Flow detection ammeter

7. 1 lamp

8.1 set of special constant temperature air conditioning (optional)
