Oscillating Granulator

Whether it be a wet powder or a pack of dry block materials, the Oscillating Granulator will develop the material into fine and consistent granules. The machine comes with an elastically adjustable wire screen mesh that is easy to assemble and disassemble. The main elements of the granulation machine are composed of an enclosed steel plated body and a lubrication system that enables it to run smoothly without producing any unnecessary noise.

The Oscillating Granulation is a popular granulating machine used for size reduction or forming the required granule sizes from moist powder material or for crushing dried block stock, sensitive powders, and granules in the pharmaceutical, chemical and food industries. swing granulation make the quality of granules better by facilitating their flowability and handling.

Oscillating Granulator Introduction

YK series swing granulators is usually the key equipment of instant granule production line. The pellet production line includes the following equipment: CH tank mixer, YK series oscillating granulators, dryer (such as vibrating fluidized bed dryer, static fluidized bed dryer, vertical fluid bed dryer or hot air oven), screening machine. This production line can make dry powder into uniform and instant granules. If the customer wants to make the final pellets into a ball shape, the wet pellets will be sent to the QL pelletizer to obtain the wet pellets and dried by a dryer.

Hywell Machinery have the laboratory machinery for the factory or experimental agency product development stage, please pay attention to hywell company's laboratory swing granulator.

Oscillating Granulators Description

The Swing Oscillating Granulator has one rotor, which oscillates on a horizontal axis. There is one screen of your required mesh size mounted at the bottom of the rotor which can be removed and remounted easily; its tension is also adjustable. Product is loaded from the top through the infeed hopper, and material falls on the rotor blade. The particles are broken down by a set the oscillating rotors as it moves from side to side. The sharp edges on the rotor, the oscillating movement of the rotor, and subsequent pressure of the product against the screen allows the size reduction of the granular material to take place as the material gets pushed through the screen mesh. (multiple screens available of various mesh sizes).

The driving mechanism of swing granulator is totally enclosed in the machine body and its lubrication system improves the lifetime of the mechanical components. These granulators are constructed with quality stainless steel to meet the GMP standard. The YK Series machine are among the most affordable oscillating granulators in the industry.

     There are different models of swing granulators to meet different output; and it is double rotor and single rotor sway granulator. Hywell machinery company mainly has YK-160 double-head granulator that named as YK-160B. The single rotor rocking granulator is a one roller installed on the main machine. But the double rotor granulator is one main machine with the two rocking rollers. Therefore, under normal circumstances, the output of a double-head oscillating granulator is twice that of a single roller oscillating granulator.

Screen Granulators Construction Material

Hywell Machinery are able to offer our YK series screen granulators with contact part to be built in SS304, SS316L, Titanium, Duplex stainless steel, etc. For the control system of sieve granulators, Hywell machinery have choices on push button, PLC+HMI and so on, and For the main electrical components of the screen granulator, it can choices the famous brand that such as ABB , Siemens or Schneider or others.

How do the Sway Granulators Works

Hywell machinery YK series sway granulator is mainly composed of a hopper, a drum, a screen, etc. The rotating drum is installed under the hopper, and there are sealed end covers at the front and rear. The rotating drum can be removed and cleaned at any time, as long as the front adjusting screw and front cover are removed Remove the three screws from the front end cover, and then the roller can be taken out.

Hywell machinery YK series swing granulator uses mechanical transmission to make the cage drum rotor reciprocate to perform forced granulation or collision crushing of the material. The gap between the screen and the rotating cage is controlled and the granules are extruded. Its production capacity is as follows The moisture, type, viscosity and mesh of the material vary, and different particle sizes can be obtained by changing the aperture of different screens.

The structure of the hopper and the granulating device is designed according to the principle of easy installation, cleaning and use. The structural materials of swing oscillating granulator in contact with the material are all made of stainless steel and non-toxic nylon, which ensures the cleanliness of the product and no chemical reaction.

Extruder Pelletizer Advantages

Hywell machinery YK series pelletizer extruder had the following advantages over conventional solutions.

1. Design is GMP - Current Good Manufacturing Practices compliance

2. All Product contact parts AISI 316 & non contact parts AISI 304.

3. Uniformly granulation & fewer fines of wet material and dry materials.

4. Easy to operate; move, clean, convenient

5. Smooth running, reliable performance, easy operation.

6. Highly polished inner and outer surfaces of the machine, no dead comer, easy to clear, no cross contamination. Confining to the requirement of GMP.

7. The feeding system for this granulating machine can be by manual or screw feeder .

8. Low noise and good seal

9. For the electrical component of rotor granulator , it can use international brand such as ABB ,Siemens or Schneider.

10. Small cubage, easy to install, convenient to operate and maintain.

Extruder Granulation Application

The YK series pelletizing extruder is widely used in pharmaceutical, chemical, foodstuff and electronic industries.

The YK swing granulator can not only be used to make wet granules from wet materials (wet powder);and it also can be used to crush and screen dry large particles to obtain uniform small particles.
