1PERALATAN PENCAMPURAN (MIXING EQUIPMENT) Dr. Ir. Meika Syahbana Rusli, MSc
2Jenis agregat komponen dalam suatu campuran : Tujuan Pencampuran:Bergabungnya bahan menjadi suatu campuran yang sedapat mungkin memiliki kesamaan penyebaran yang sempurnaJenis agregat komponen dalam suatu campuran :Campuran gas ;Contoh : udaraCampuran bahan cair;Contoh : larutan, emulsiCampuran bahan padat-bahan cair;Contoh : suspensi, pastaCampuran bahan cair-gas;Contoh : minuman yang mengandung CO2
35. Campuran bahan padat;Contoh : pakan ternak, adukan semen pasir6. Campuran gas-bahan padat;Contoh : asapHomogenisasi campuran jenis 1 dan 6 dilakukan dengan bantuan aliran turbulen melalui pompaHomogenisasi campuran jenis 2 s/d 5 dilakukan melalui :A. pengadukanB. pencampuran bahan viskousC. pencampuran bahan padat
4Pengadukan bahan cair Tujuan : a. Mensuspensikan bahan/partikel padat b. Menggabungkan bahan-bahan cair yang dapat salingbercampurc. Mendispersikan gas dalam bentuk gelembung gas halusd. Mendispersikan bahan cair lain yang tidak dapate. Meningkatkan pindah panas antara bahan cair danpenukar panasDalam suatu proses pengadukan, beberapa tujuan tersebutdiatas dicapai secara sekaligus.Contoh : proses hidrogenasi katalitis minyak nabati
5Rancangan alat pengauk (agitators) Secara umum agitator terdiri dari :1. bejana (vessel)2. sumbu berputar (As)3. pengaduk (impeller)4. penggerak (motor)5. pemecah aliran (buffle)
6Lee AgitatorsAll Lee agitators feature a unique offset frame construction which brings the points of the scrapers to the centerline, thus insuring uniform scraping action throughout the entire processing cycle. Lee agitators also offer sanitary advantages and an opportunity to reduce operating costs as they do not have to be removed and broken down for cleaning. Lee agitators are available in various standard styles and sizes, also.
7Other features include: Exclusive centerline scraper assembly assures uniform scraping and complete mixing. Scrapers are hinged to the frame above and back of the center at a steep pitch, thus moving the heated film of the product continuously toward the center of the kettle.Option of fixed or variable speed, electric or hydraulic motors.Agitator drive mounted in a heavy stainless steel channel with special lip seal to prevent leakage into product.Choice of hydraulic cylinders for easy tilt-out of agitator.USDA approved scraper blades available in a choice of quality materials, including: molded nylon, nickel alloy castings, and Teflon.Fully-enclosed gear box with heavy-duty gears assures reliability and long life. Lee assembles, tests and runs all agitator assemblies before shipment.Standard agitator is supplied with a USDA approved bottom support bushing.All scraped-surface agitators can be installed at an incline in hemispherical bottom vessels.

15FEATURE FOR DISPERSION KNEADER: 1. It has an automatic temperature and time control system to provide a 100% mixing effect.2. Easy to clean chamber and changing colours.3. It mixes compounds in 6~10 minutes per batch equivalent to 2 units of mixing Roller.4. Pressurized and sealing mixing chamber to provide high mixing performance and prevented environmental pollution.5. Easy to installation, operation and maintenance to lower the running cost.
17Excellent for kneading and mixing of highly viscous materials like dough, putty, rubber solutions, adhesives, polymers etc. The mixing action is a combination of smearing, stretching, folding, dividing and recombining as the material is processed between the sigma blades and the container walls. Jacket arrangement is provided for heating or cooling application. In bigger models the container is tilted by a hydraulic cylinder to ensure complete discharge of mass.
20Pencampuran partikel padat Karakteristik proses pencampuranBahan padat datat mengalirPrinsip hampir sama dengan pencampuran bahan viskousMembutuhkan tenaga yang lebih ringan/kecil dari pada pencampuran bahan pastaTidak ada aliran bahan ke pengaduk dengan sendirinyaCara kerja : kocokan mekanik, angkat dan jatuhkan dan menggelindingkan bahan

52General This Mixer is applicable for mixing powdery or granular materials in pharmaceutical and other industries. It consists of two V-Type cylinders of different altitudes, and through mechanical transmission, the materials in these cylinders are made to move back and forth and turn over again and again, thereby achieving the goal of uniform mixing. This Mixer has the following distinguishing features, no blind angle in the cylinders, no accumulation of materials, high speed, and short mixing time. With the body made of stainless steel and both inner and outer walls polished, the cylinders have elegant appearance the charging of materials can be made either by manual operation or through vacuum suction. For discharging, rotating valves and rapid swivel heads are adopted.

56For mixing of foundry chemicals, pastes,moulding sand, foundry fluxes, food colours etc where an amount of binder or aggalomerate is to be blended into the material. Also used for densification of the mix. The pan is stationary inside which rotate heavy duty mullers / rollers . The heavy wide rollers ride over the material where intensive crushing, shearing and mixing action takes place. Scrappers and ploughs are provided for directing the mass into the path of the rollers.The machine is also available with granite rolls and pan.
