Sifter Machine-1

A sifter machine is designed in a way that it provides scaling, sorting, and scoring of materials that are processed in pharmaceutical, food processing, chemical of cement industry. Basically, a sifter machine separates all the grading material and each process is carried out in a single machine which makes it much economical. Principle of vibration takes places where gradients of higher mass are isolated from the remaining material.   

In a highly efficient manner, particles are more likely sent to a circular rotating frame and materials like solids are separated from solids and likewise solids from liquids are also separated depending upon material grading.

Uses of a Sifter Machine

A sifter machine provides highly versatile way to separate particles of different grading from the system. Some of the most common uses of a sifter machine are

Uses of a Sifter Machine

Sieving

As the name states, sieving is usually done at the initial stage of sorting. Here particles are sorted out from the system. The lumps or extra size materials which are resulted of extended storage are merely removed here.

Fine materials can be removed using the mesh in case of sieving. Examples are of particles like tags, strings present in flour can easily be removed using sifter machine and then the flour in pure form can be used for food purpose.

Screening or Grading

Another important use of a sifter machine is screening or grading. It simply states that unwanted particles are separated from its actual dimension. The processes where different particles are very close in dimensions but difficult to separate, sifter machine separates them according to their sizes. Highly efficient way of distinguishing materials is carried out in screening or grading process.

Scalping

The most important use of a sifter machine is scalping. In this phenomenon, lumps or unwanted objects are extracted on the scalping film in a sifter machine. Particles like tags, swings, twigs are commonly removed in this process. The opening of mesh is comparative large for scaling that the size of product which allows scalping of high material quantity to be done easily.

Shifting

Additionally, sifter machine also shifts particles of same type to their directed ways. Shifting basically means to make the particle travel on their actual paths. Like if a piece of stone is separated from floor. Both will be shifted in separate directions so that they might not get interacted again.

industries these sifter machines

Sifter machine due to its versatile ability of separating particles from materials is mostly used in pharmaceutical, food processing, chemical and cement industry. These industries commonly use sifter machines because their products contain unwanted particles that are mandatory to be separated. Pharmaceutical industry at one place has the greatest usage of sifter machines due to its high efficiency and compact design.  

industries these sifter machines-1

In a pharmaceutical it is always necessary to separated unwanted material because batch production is carried out and the size of medicines is too small. Product quality remains same in every production batch as no granular or unwanted particle enters the system.

Working Principle of a Sifter Machine

There is a simple process of sifter machines in which parts are separated from the whole material. The process of machine is as follows

Working Principle of a Sifter Machine

  • Initially all the components of a sifter machine like power supply, cleaning is checked and cover, screen structure, bottom frame are tightened with clamping rings to confirm smooth production flow.
  • After that the operator pours the complete material through the feeding hopper of a sifter machine and turns the power on. As the motor gets energized it enables the vibratory motion of frame and off-balances the weight assembly.
  • In the third step, the sieve operation starts vibrating and therefore the granules placed on the hopper moves around the sieve. It passes through that area and is specified in equal counting.
  • After sieving, the particles are separated from the unwanted ones and travel through a regulated path. The material completely gets rid of larger or unwanted particles only depending on the size of screen.

The process is repeated only if unwanted particles are left otherwise the pure material is collected at the bottom deck discharge of a sifter machine.

Types of Sifter Machine

Types of Sifter Machine

Based on Operation

Sifter machines were traditionally used at households or at small scale in which sorting was done manually. Nowadays, sifter machines available are mostly automatically operated. They can be round shaped or square shaped.

In automatic sifter machines, only the material is feed by the operator, rest all the separation process is done by the machine itself.

Based on Application

Other than this, sifter machines are only differentiated based on its applications or productivity. Single, double, and triple layer sifter machines are available depending on the production rate of any industry.

Components of a Sifter Machine

Some of the components of a sifter machine are

Components of a Sifter Machine

Motor

Motor

A motor is the main component of a sifter machine which powers the whole machine and allows the screens to vibrate. Electrical power is given to these motors which are further converted into energy or mechanical form. Once the moment gets smooth through proper rpm of motor, the material is feed in the hopper lid. Depending on the production capacity and volume, selection of motor rating holds significant importance.

Hopper Lid

Hopper Lid

This is the cover from where the material is poured in the sifter machine. It is present at the upper section of machine so that the machine can easily travel through each level. It is mostly made up of metallic material and due to that it prevents contamination of material. It is clamped in a way that no external particle enters the mesh and keeps the complete system safe.

Filter Screen

The most important part of a sifter machine is “Filter Screen”. It ensures smooth surface during processing of fabric. A wire mesh surface is there in a filter screen, and it helps the machine to perform the sieving process. In addition, any type of leakage of material is also prevented using this screen.

Wire mesh screen

Wire mesh screen

The wire mesh screen is embedded on the circular components with a special type of glue so that the mesh has an extended lifespan. It vibrates no matter what intensity of vibration is there or how much heavy the particles are.

Screen material outlet

Screen material outlet

A screen material outlet is the opening from where the screened, graded, or heavy sized material are gathered and taken out of the system so that they no longer be a part of process. Therefore, it is present at the lower section of filter screen.

Springs

Springs

The hydraulic movement is mainly enhanced using these springs. They are the one which holds the upper section of the sifter machine. It keeps the whole system intact that during vibration no part follows different path.

Free vibration in sifter machine is carried out because of these springs. The machine efficiency is also supported by these springs.

Control panel

Control panel

The operator or concern interact the system with this main control panel. Data and other protocols are entered through control panel. It consists of selectors and buttons that are used to set all machine parameters.
