High Quality Alloy Steel Fish Feed Machine Spare Parts

Spare parts are made of stainless steel alloyed material, that is resistant to elevated temperatures, excellent in hardness and good in abrasion resistance. The polished spiral surfaces allow the material to flow smoothly, and different shapes can meet user’s requirements by controlling the mould.

Fish feed extruder comprises of hopper, a barrel which houses, the screw conveyor, the cutting knife, the die, a heater etc.

Screw Shaft
Screw shaft is the main component of extruder. The parameters of screw structure include diameter, pitch, root diameter, helix angle and section structure. The ratio of length to diameter of the extruded parts and the clearance between the screw and the inner wall of the expansion chamber also have a great influence on the performance of the extruder. The screw is made of high quality alloy steel, has the advantages of high temperature resistance, wear resistance, corrosion resistance, etc.
Blade Carrier 
Screw Head
Discharge Die
Discharge die is the last part, it has a great influence on the product’s shape, texture, density, appearance, features, and the output of the extruder.
Pressure Ring
Single Screw Fish Feed Extruder: When using different sizes of pressure rings, from the inlet to the outlet, the size of the pressure ring is usually from small to large. Blades
They are stainless steel blades, have the advantages of wear resistance, high hardness and sharp edge. All of them are customized for drawing instead of inventory.
