Continuous Screw Flight Rolling Spiral Blade Auger Knife

Auger Knife Features

1. The spiral forming speed is fast, the production efficiency is high, the material utilization rate is high, the rigidity is good, and the strength is high. ; 2. The welding assembly is convenient and quick, and the overall strength is good; 3. The thickness of the outer edge is about 1/2 of the thickness of the inner hole, but after hardening by rolling and cooling, the hardness of the outer edge is more than doubled, which correspondingly compensates for the wear resistance of the outer edge; 4. Heat treatment can be carried out according to requirements to improve the surface hardness of the blade and improve the wear resistance; 5. The forming size is limited; only the spiral blade of low carbon steel material with a thickness ≤ 8mm and the maximum radius difference (outer diameter/2-inner diameter/2) ≤ 165mm can be formed; 6. The one-time debugging before production consumes high materials, which is not suitable for a one-time small batch supply of one specification, and there is a minimum order quantity requirement. Product material: SPHC Product specifications: Within the scope of meeting the following table, customized production according to customer requirements.

Inner hole plate thickness (mm)	Minimum inner diameter (mm)	Maximum outer diameter (mm)	Maximum radius difference (mm)	Pitch outer diameter ratio	Outer diameter inner diameter ratio
3.0	20	500	165	0.6-1.3	4.0
3.5	20	500	165	0.6-1.3	4.0
4.5	28	500	165	0.75-1.3	4.0
5.0	28	500	165	0.8-1.3	4.0
6.0	40	500	165	0.8-1.2	4.0

Customized service of Auger Knife

1. If the inner diameter of the customized specification is required to be within the range of the minimum inner diameter + 5mm, the maximum outer diameter of the specification cannot exceed three times the inner diameter. 2. For orders whose plate thickness is not within the range of the above table due to material preparation reasons, the product weight for one order must be greater than 15 tons.

We can also supply all the parts for the feed mixer.
