Macam - Macam Conveyor

 Conveyor yg sering digunakan utk pengangkutan bahan baku ada beberapa seperti :

        1.  Belt Conveyor, bentuk seperti sabuk panjang yg berputar, bisa terbuat dari karet, plastik, kulit atau logam tergantung bahan yg diangkut, digunakan utk pengangkutan datar, miring ( < 15 – 20 ° ). Bisa digunakan utk mengangkut karung, pasir dll

Keuntungan :

• Fleksibel dalam penggunaan, bisa datar / miring
• Desain sederhana
• Tingkat kebisingan rendah
• Proses kontinyu
• Mampu membawa beban berkapasitas besar
• Daya yg dibutuhkan kecil
• Bisa diatur kecepatan sabuk shg didapatkan material yg dipindahkan per jamnya

Kelemahan :

• Kemiringan terbatas ( < 15 – 20 ° )
• Hanya bisa dipasang lurus
• Perawatan mahal
• Sabuk rentan rusak

Conveyor which is often used for the transport of raw material are :
      1.  Belt Conveyor, form like long belt that rotates, can be made from rubber, plastic, leather or metal depending on the material is carried, used for flat, sloping  ( < 15 – 20 ° ). Can be used for transport of sack, sand etc.

"Advantages :

• Flexibel in use (flate / slope)
• Simple design
  
• Low noisy
• Continuous process
• Ability bring large load capacity
• Small power
• Can be set velocity of belt so got material is transported per hours

Disadvantages :

• Limit slope  ( < 15 – 20 ° )
• Only flat use
• Expensive maintenance
• Belt vunerable to damage"

      2.  Bucket Elevator, bentuk seperti timba yg berputar dan mengambil material dari bawah ke atas oleh rantai.
Keuntungan :

• Bisa digunakana utk kemiringan curam / tegak lurus sampai 50 m
• Harga murah karena pemakaian energi kecil
• Tempat lebih sempit
• Dapat digunakan utk macam2 material (kering, lengket atau basah)

Kelemahan :

• Bahan yg diangkut bisa saja jatuh ke bawah
• Tidak bisa digunakan utk jalur berbelok
• Kebersihan bahan yg diangkut tdk terjaga
• Kecepatan rendah

      "2.  Bucket Elevator, shape such as bucket that rotates and take the material from below to above by chain.
Advantages :

• Can be used for steep slope / vertical until 50 m
• Cheap cost due to use small energy
• Place narrower
• Can be used for kind of material (dry, sticky or wet)

Disadvantages :

• Material is carried can falling down
• Can't be used for turn line
• Cleaning of material transported is not awake
• Low speed"

      3.  Screw Conveyor, bentuk seperti sekrup bisa tunggal / ganda yg berputar pada poros, sehingga material akan terangkut melewati celah sekrup dan dibawa ke ujung.

Keuntungan :

• Biaya sedikit
• Efisien tempat
• Fleksibel utk horizontal atau kemiringan (namun tdk tajam)
• Bisa digunakan utk material panas, berdebu dan lengket
• Memungkinkan pengeluaran bahan pada semua titik pada sekrup di casing
• Perawatan mudah
• Desain sederhana

Kelemahan :

• Timbul gesekan antara bahan dg sekrup shg konsumsi daya tinggi
• Kapasitas rendah
• Terbatas utk material curah

      "3.  Screw Conveyor, shape such as screw (single or double) which it rotates at shaft, so material is carried through screw gap and bring to the end

Advantages :

• Low cost
• Efficient of space
• Flexibel in horizontal or slope (but not steep)
• Can be used for hot material, dusty, and sticky
• Ability outlay material at all spot in the screw casing
• Easy maintenance
• Simple design

Disadvantages :

• Happen friction between material with screw so high energy consumption
• Low capacity
• Limit for bulk material"

      4.  Scrapper Conveyor
Keuntungan :

• Harga murah
• Dapat beroperasi pada kemiringan tdk boleh > 30 °

Kelemahan :

• Tenaga tdk konstan
• Jarak transport pendek
• Biaya perawatan besar

      "4.  Scrapper Conveyor
Advantages :

• Cheap cost
• Can be operated at slope can't  > 30 °

Disadvantages :

• Unconstant power
• Distance transport is short
  
• Large maintenance cost"

Scrapper Conveyor

      5.  Apron Conveyor
Keuntungan :

• Dapat digunakan utk material kasar dan berat
• Perawatan murah
• Dapat digunakan utk kemiringan 25 °

Kelemahan :

• Kapasitas pengangkutan kecil
• Bekerja searah saja
• Kecepatan rendah
• Pembuatan rumit
• Biaya tinggi

      "5.  Apron Conveyor
Advantages :

• Can be used for rough and tough material
• Low maintenance
• Can be used for slope 25 °

Disadvantages :

• Small capacity
• Working in the same direction
  
• Low speed
• Difficult making
• High cost"

      6.  Pneumatic Conveyor, prinsip kerja mengalirkan material dalam pipa dg bantuan udara bertekanan
Keuntungan :

• Perawatan kecil
• Digunakan utk material curah dan bongkaan kecil
• Fleksibilitas pengangkutan
• Pengoperasian murah

Kelemahan :

• Energi yg dibutuhkan besar utk pengangkutan sama

      "6.  Pneumatic Conveyor, working principle flowing material in pipe with pressure air
Advantages :

• Small maintenance
• Used for bulk material and small pieces
• Flexibel in transport
• Cheap operation

Disadvantage :

• Need the large energy for same transportation"
