Like water pump Motor mower Small plow car
2. use compressed air and solvent 2.1
. Air compressed hydraulic system (Hydraulic press) will be approximately 20-25% oil and gasoline was down 25% in approximately 10-waste and waste oil in the hold for about 10-15%, but they're mixed
2.2 compressor system, compression machine screw (Screw press) will be approximately 25-30% oil and oil residues in sewage for about 5-10%
2.3 chemical extraction, petroleum ether is 35-38% oil seeds, Jatropha, oil will be 3-4 kg 1 liter
