1.What Is A Sifter Machine?
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.
2.In Which Industries Are These Sifter Machines Mostly Used?
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.
In a pPharmaceutical 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.
Contaminants are removed from food process through these sifter machines. Large and medium scale industries are using these machines in their manufacturing processes to get rid of large, unwanted granules particles and other products.
3.What Are The 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
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.
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.
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.
4.What Are The 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
- 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.
5.What Are The Main Components Of A Sifter Machine?
Components of a Sifter Machine
Some of the components of a sifter machine are
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.
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.
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
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
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.
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.
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.
There may be other main components in different type of sifter machine, but these main parts are the most important ones that in the main types of this machine.
6.What Are The Types Of Sifter Machine?
The types of sifter machines are based on application and operation
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.
7.What Are The Differences Between Circular And Square Vibrating Sifter Machines?
Medical, food, cosmetic, chemical and pharmaceutical industries always show greater concern while selecting the vibrational motion of particles and its outcomes. For this there are two types machine depending upon motion of particle. The difference between both of them are
Circular Vibrating Sifter Machine
Circular motion vibrating sifter machines are ideally used in small and medium scale industries to segregated heavy particles from wet and dry materials. Machines are highly precise and gives accurate output to 99%. Pharmaceutical industries are the highest buyers of circular sifter machines.
Square Vibrating Sifter Machine
RectangulaSquare vibrating sifter machines are ideally used for segregation of huge particles in large scale industries. Sieving of PVS, PVC and laminated are the best application of a type of machines. A unique advantage of rectangular sifter machine over a circular sifter machine is that it does not produces sound at any level and requires less machine maintenance.
8.What Are The Advantages Of A Sifter Machine?
Some of the advantages of a sifter machine
The efficiency of a sifter machine can be judged in a way that it can separate particles even if they are of same size or dimension. It also guarantees high speed with minimal noise pollution.
These machines utilize less power and produce greater output. This makes them energy efficient and allows the manufacturer to earn a lot with less power consumption.
Ease of Maneuverability
This feature basically explains the ability of sifter machine to move from one place to another. It can be shifted wherever required without any hurdle or installation difficulties.
Sifter machines are highly productive with capability to remove any type of unwanted particle regardless of its size or dimension. Liquids as well as solids both are produced with higher output rate.
Ease Of Operation
The machine is designed in a way that no such expertise is required to understand the process. Also, the handling and maintenance cost of machine makes it very economical.
A sifter machine is made up of high-grade stainless steel which makes it rust repellant and helps it to last for long duration. The design is much compact that it can easily be moved from one place to another.
Parts used in a sifter machine are of high quality and do not easily require any change. Also, tools are not required for quick change. This makes the machine capable of having no downtime and process in a smooth manner.
9.How Can A Suitable Mesh Screen Be Chosen For A Sifter Machine?
The most important part of a sifter machine is its mesh screen. It requires greater concern that while selecting a sifter machine, few important considerations should be done. Those important points are
- The opening size of a mesh screen should be referred to the standards according to materials. Commonly the sizes of hole ranges between 0.5mm to 50mm.
- Another important consideration is that the fiber length in it should lie in between 2mm to 6mm.
- Thickness of a mesh screen present in sifter machine requires high level of sensitivity. The gauge of mesh screen between 1/16” to 1” is always a better option.
- The size of material should also be suitable for a sifter machine. As heavy material can easily damage the mesh so mesh size should be selected that is durable with the external material weight.
10.How Many Types Of Vibrating Screens Are There?
Vibrating screens are commonly rotatory in nature. The movement of particles are vibrated in circular rotation and then separated from heavy unwanted substances. In the modern world there are three types of vibrating screens based upon the chemical composition of mesh used in screens. The types are
Carbon Steel Vibrating Screen
The most commonly used vibrating screens in a sifter machine is carbon steel vibrating screen. No particular requirements are required in for material when it is screened under a carbon steel vibrating screen. Mostly capsule powders are applied on this type of screen to get rid of hard particles. Fine grinding of products can be achieved by these vibrating screens and this is why these are recommended by most of the industrial experts.
Anti-Corrosion Plastic Vibrating Screen
As the name states an anti-corrosive plastic vibrating screens are used to avoid contamination and corrosion caused by continuous direct contact of material with the machines surface. During an industrial process the material always remain in the sifter machine and has chemicals in it. This chemical after sometime shows chemical reaction with the metal screen and effects it a lot. Due to poor conditioned vibrating screen no ideal readings can be achieved too.
This is why non-metallic material parts are made for those screens that are in direct contact with the vibrating screen. By this the problem of chemical reaction is completely eliminated. Anti-corrosive plastic vibrating screens are suitable for industries in which filtration and screening of powdered products is carried out.
Stainless Steel Vibrating Screen
Stainless steel and all stainless steel are two types of material of which these vibrating screens are made up of. Equipment and materials those are always in direct contact require high level of protection. So, for prevention of contamination and other environmental effect it is suggested to use a completely stainless steel vibrating screens.
These vibrating screens are most suitable to be used in food and pharmaceutical industries where most chances of contamination are present due to chemical and medical materials. While using a stainless steel or all stainless steel, the cleaning process of machine becomes much easier and helps the operator to maintain the machine for longer productivity.
11.What Are The Common Faults That Are Faced In A Sifter Machine?
Some of the common problems that occur during the operation of a sifter machine are
|1||Quick Outflow of Material||Excessive inflow of material||Minimize the product inflow|
|2||Improper placement of motor vibrator||Proper adjustment of vibrator|
|3||Insufficient Efficiency||Clogged Screen||Clearing the screen will remove it.|
