Abstract

Screw feeder merupakan pesawat pemindah bahan khususnya material curah yang sangat penting dalam dunia industri untuk meningkatkan produktivitas kerja dan effisiensi waktu. Perumusan kapasitas screw feeder selama ini hanya memperhitungkan dimensi atau tipe screw saja dan tidak melibatkan sifat material curah, sehingga terjadi penyimpangan pada hasil perancangan dan konstruksi tidak efektif atau bahkan tidak bisa dioperasikan, sehingga diperlukan met ode analisa lain yang lebih baik. Pada tugas akhir ini, analisa dilakukan dengan pendekatan baru untuk merumuskan kapasitas screw feeder yaitu dengan menggunakan pemodelan matematis dari interaksi material curah dengan screw flight. Perumusan ini didasarkan pada arah gerak material di dalam screw yang ditentukan oleh besarnya sudut gesek material dan dimensi screw. Dari hasil analisa didapatkan bahwa perpindahan material curah dalam satu putaran screw, lebih kecil dari panjang pitch screw. Semakin panjang pitch screw menyebabkan perubahan kapasitas semakin sensitif terhadap perubahan sudut gesek material (rp), dimana dengan kenaikan rp semakin besar pitch screw menyebabkan penurunan kapasitasnya semakin besar. Untuk mendapatkan kapasitas pemindahan maksimum suatu material, harus digunakan screw feeder dengan perbandingan PID tertentu tergantung sudut gesek materialnya

Screw feeder is a material transfer device, especially bulk material, which is very important in the industrial world to increase work productivity and time efficiency. The formulation of screw feeder capacity so far only takes into account the dimensions or types of screws and does not involve the properties of bulk materials, resulting in deviations in the design results and ineffective construction or even inoperability, so that other, better analysis methods are needed. In this final project, the analysis is carried out with a new approach to formulate the screw feeder capacity, namely by using mathematical modeling of the interaction of bulk materials with screw flights. This formulation is based on the direction of material movement in the screw which is determined by the magnitude of the material friction angle and the screw dimensions. From the analysis results, it was found that the displacement of bulk material in one screw rotation is smaller than the length of the screw pitch. The longer the screw pitch causes changes in capacity to be more sensitive to changes in the material friction angle (rp), where with an increase in rp, the greater the screw pitch causes a greater decrease in capacity. To obtain the maximum transfer capacity of a material, a screw feeder with a certain PID ratio must be used depending on the friction angle of the material
