Abstract
Rollers and dies are essential components in pelletizer machines that often experience wear due to high friction forces. This issue not only affects production efficiency but also shortens the lifespan of the components. This study aims to analyze the effects of friction force and the addition of roller pressure on wear levels and the efficiency of wood pellet production. The research was conducted using roller pressure variations of 0 kg.m, 2 kg.m, and 3 kg.m. The collected data included friction force, wear rate, and production efficiency. The research methodology involved measuring centrifugal force, normal force, and friction force acting on the roller and die at different pressure levels. Subsequently, an analysis was conducted on component wear rates and pellet production efficiency in each test. The results showed that increasing the roller pressure from 0 kg.m, 2 kg.m, to 3 kg.m significantly reduced the friction force from 53.64 N, 43.53 N, and 39.52 N, respectively. At a roller pressure of 3 kg.m, production efficiency reached 88.83%, compared to 28.73% without pressure and 60.03% with 2 kg.m pressure. The roller wear also decreased from 0.15 mm (without pressure) and 0.1 mm (with 2 kg.m pressure) to 0.05 mm (with 3 kg.m pressure), while die wear was reduced from 0.2 mm (without pressure) and 0.15 mm (with 2 kg.m pressure) to 0.1 mm (with 3 kg.m pressure). The addition of roller pressure affects production efficiency and reduces the wear rate of the roller and die components. The optimal condition was achieved at a roller pressure of 3 kg.m, which resulted in the highest production efficiency and the lowest wear rate. Keyword: Frictional Force, Pelletizer Machine, Roller, Die, Pressure, Production Output, Wear, System Efficiency Roller dan die adalah komponen penting dalam mesin pelletizer yang sering mengalami keausan akibat gaya gesek tinggi. Masalah ini tidak hanya memengaruhi efisiensi produksi, tetapi juga memperpendek umur pakai komponen. Penelitian ini bertujuan untuk menganalisis pengaruh gaya gesek dan penambahan tekanan pada roller terhadap tingkat keausan serta efisiensi produksi pelet kayu. Penelitian dilakukan menggunakan variasi tekanan roller sebesar 0 kg.m, 2 kg.m, dan 3 kg.m. Data yang dikumpulkan meliputi gaya gesek, tingkat keausan, dan efisiensi produksi. Metodologi penelitian melibatkan pengukuran gaya sentrifugal, gaya normal dan gaya gesek yang terjadi pada roller dan die dengan berbagai tingkat tekanan. Selanjutnya, dilakukan analisis tingkat keausan komponen dan efisiensi produksi pelet pada setiap pengujian. Hasil menunjukkan bahwa peningkatan tekanan roller dari 0 kg.m, 2 kg.m, dan 3 kg.m dapat menurunkan gaya gesek secara signifikan, dari 53,64 N, 43,53, dan 39,52 N. Pada kondisi tekanan roller 3 kg.m, efisiensi produksi mencapai 88,83%, dibandingkan dengan tanpa tekanan 28,73% dan tekanan 2 kg.m 60,03%. Tingkat keausan roller juga menurun dari 0,15 mm (tanpa tekanan), 0,1 mm (tekanan 2 kg.m), menjadi 0,05 mm (tekanan 3 kg.m), sedangkan keausan die berkurang dari 0,2 mm (tanpa tekanan), 0,15 mm (tekanan 2 kg.m), menjadi 0,1 mm (Tekanan 3 kg.m). Penambahan tekanan roller mempengaruhi efisiensi produksi dan mengurangi tingkat keausan komponen roller dan die. Kondisi optimal tercapai pada tekanan rollersebesar 3 kg.m, yang menghasilkan efisiensi produksi tertinggi dan tingkat keausan terendah.
