PERANCANGAN VIBRATING SCREEN KAPASITAS 60 TON/JAM UNTUK KEBUTUHAN EKSPOR CANGKANG KELAPA SAWIT

---

This study aims to design and analyze the structure of a vibrating screen
machine with a capacity of 60 tons/hour, used for screening palm shells. The
machine has a screen dimension of 6 m x 2.8 m with a mesh size of 7 mm and a
slope of 15 degrees. The driving power of 30 HP from the motor, rotating at 3240
rpm, is transmitted through pulleys configured with 5 inches on the motor and 9
inches on the shaft, generating a shaft rotation of 1800 rpm with an amplitude of
10 mm from an unbalanced mass of 92 kg. The system uses a 100 mm diameter
shaft made of S30C-D material and SKF 22316EK spherical roller bearings with
an inner diameter of 80 mm. The compression spring used has an average
diameter of 100 mm, wire diameter of 16 mm, 7 coils, and a length of 400 mm.
Structural analysis was conducted manually on the shaft, vibrating screen frame,
and support leg frame. The analysis results show that the shaft experiences a
maximum moment of 318,320 N.mm at bearing position A, with a shear force of -
2,045 N at position (2,242 mm < x < 2,378 mm). The von Mises stress on the shaft
is 3 MPa with a safety factor of 200. On the vibrating screen frame, the maximum
moment is 34,750 N.mm with a shear force of 139 N, resulting in a von Mises
stress of 4.3 MPa with a safety factor of 84. Meanwhile, on the support leg frame
made of UNP 100x50x5 mm steel, the maximum moment is 52,650 N.mm with a
shear force of 3,511 N, resulting in a von Mises stress of 18 MPa with a safety
factor of 20. Based on the analysis results, the designed vibrating screen machine
structure has adequate strength with a high safety factor, making it safe and
efficient to operate for screening palm shells with a capacity of 60 tons/hour.
