In this video i was making Blet Grinder 2x72.
I was using drive wheel diameter 150mm , because i will use Belt grinder mostly for metal, that gives above-average speedof 22.7 m/s (79,2 km/h). This speed is great for metal dont burn tree as u can see in video.
If u want to reduce speed of belt or accelerate, u can do it by swaping your drive wheel (speed depends on drive wheel diameter).
This is formula with u can calculate speed:
(d*3.14*n):60000
d- diameter of drive wheel
n- number of revs of your engine
I was satisfyed but i will suggest to use fatter material.
I was using profile 35x35x2mm i 40x40x2mm but I would recommend you to use a profile with thicker steel (preferably 5 mm).
Engine that i used:
power: 1.5kw
speed: 2900rpm
weight: 23kg
single-phase
Wheel dimension:
60x80mm x2
80x80mm
150x80mm
I would suggest you that wheel should be from plastic, because plastic is most resistant to wear.
I used 32x12x10mm bearings. I suggest using high speed bearings so they can last longer (for 8000 rpm).
Dimension of belt: 70x2000mm.
