EXPERIMENTAL STUDY AND ANALYSIS OF FLAT BELT CONVEYER SYSTEM WITH DIFFERENT WEIGHT CONDITION

A conveyor belt system essentially consists of an endless belt of elastic material connected between two flat pulleys and driven by the rotation of one of the pulleys by a direct current motor. Usually, the material is fed to the belt near the other end of the pulley. The moving belt that carries the material to the drive pulley tends to sag between the two end pulleys due to its own weight. Rubber conveyor belts are commonly used to transport items with uneven bottom surfaces, small items that fall between rolls, or product bags that sag between rolls.

Tests of Belt Linear Speed for Identification of Frictional Contact Phenomena

In the locations where driving forces are transmitted, the changing tensile forces cause rapid elastic deformations of the belt. The deformation changes the belt speed. Measurement of the belt speed on the friction contact sections is essential to identify elastic slippage. However, the scale of the phenomenon is small, so it is necessary to use precise measuring equipment. The article presents measurements of the linear belt speed with the use of various sensors and measuring devices. A measurement error was determined for each of the presented measurement methods. The method with the highest accuracy was used to identify the elastic slippage on the drive pulley.

Perhitungan Perencanaan Mesin Pengaduk Middle Waste Asbes Kapasitas 2500 Liter

In the company PT. Headquarters of Tunas Utama produces quite a lot of waste so that there needs to be a treatment to accelerate the waste processing. The problem is how to make the waste can be processed quickly so that it can be processed to be included in the production process so that there is no buildup of waste. Planning an agitator asbestos waste mixer machine, where the equipment or machine serves to accommodate the middle waste before entering into the mixing process and stirring continuously to avoid sedimentation. In this final project, the right type of agitator will be selected for the waste mixing process, then count the existing engine elements such as the type of mixer, motor, transmission, and shaft. So that it can produce the right mixer. From the results of the calculation of the mixer using a motor with a power of 0.5 HP with a reducer of 1:30, the transmission system uses a v-belt and a pulley with a drive pulley diameter of 129 mm and a driven pulley diameter of 200 mm, resulting in a rotation of 30 rpm. For the stirrer, using a paddle stirrer with a drive shaft diameter of 50 mm.Keyword : Machine element, Planning,Waste, Agitator Didalam perusahaan PT Djabes Tunas Utama menghasilkan waste yang cukup banyak sehingga perlu adanya penanganan untuk mempercepat proses pengolahan waste tersebut. Permasalahannya adalah bagaimana cara agar waste tersebut dapat diolah dengan cepat sehingga dapat diproses untuk dimasukkan pada proses produksi sehingga tidak terjadi penumpukan waste. Maka dari itu perlu adanya mesin pengaduk untuk mengaduk middle waste tadi agar tidak terjadi pengendapan. Dan mesin pengaduk tersebut banyak macamnya. Dan akan direncanakan sebuah mesin pengaduk waste asbes jenis agitator, dimana peralatan atau mesin ini berfungsi untuk menampung middle waste sebelum masuk ke proses mixing dan dilakukan pengadukan secara terus menerus untuk menghindari pengendapan. Pada tugas akhir ini akan dipilih jenis agitator yang tepat untuk proses pengadukan waste tersebut, kemudian menghitung elemen-elemen mesin yang ada seperti jenis pengaduk, motor, transmisi, dan poros. Sehingga dapat menghasilkan mesin pengaduk yang tepat. Dari hasil perhitungan mesin pengaduk tersebut menggunakan motor dengan daya sebesar 0,5 HP dengan reducer 1:30, sistem transmisi menggunakan v-belt dan pulley dengan ukuran diameter pulley penggerak sebesar 129 mm dan diameter pulley yang digerakkan sebesar 200 mm, sehingga menghasilkan putaran sebesar 30 rpm. Untuk pengaduknya menggunakan jenis pengaduk paddle dengan diameter poros penggerak sebesar 50 mm.Kata kunci : Elemen mesin, Perencanaan, Waste, Mesin pengaduk (agitator)

PENGARUH VARIASI DIAMETER PULLEY PADA MESIN PERAJANG BAWANG MERAH TERHADAP KAPASITAS RAJANGAN

This study of the influence of variations in pulley diameter driven on shallot chopper machines against the chaff yield capacity is motivated by the production and consumption of shallots in Indonesia is quite high, so it takes a red onion chopper machine to facilitate the handling and processing. The purpose of this study was to make a shallot chopper machine, to analyze the effect of variations in pulley diameter on the yield of onion chopping, and to analyze the results of onion chopping. In this study, the analyzed were chopper speed with variations in pulley diameter driven 6 inch, 7 inch, 8 inch and 1½ inch drive pulley diameter. The test method uses 200 grams of shallots per experiment with repetitions three times the experiment with variations of pulley driven 6 inches, 7 inches, and 8 inches. After testing, an analysis of the data obtained in the form of chaff yield capacity is completed. The best test results were obtained using variations in pulley diameter driven by 6 inches with a chopping yield capacity of 3.77 grams / second.
