120 Pin-type Rubber Extruder: Low Output and Poor Efficiency—Solutions
Reasonably increase the screw speed.
Pin‑type screw extruders exhibit strong shear‑mixing performance; by appropriately increasing the main unit’s rotational speed—without causing material scorching or compromising product quality—you can directly boost the discharge rate.
Optimized segmented temperature control
The barrel, cylinder, and die temperatures should be adjusted appropriately according to the type of rubber. If the temperature is too low, the compound exhibits poor flow and slow extrusion; at an optimal temperature, the compound’s plasticity improves, extrusion becomes smoother, and output increases.
Inspect and replace the adapter die.
A too‑small die outlet or an improperly designed flow channel can directly restrict flow. Replace it with a dedicated die that offers higher throughput and smooth flow paths to reduce discharge resistance and boost production capacity.
Ensure continuous and uniform feeding.
Eliminate material interruptions and uneven feeding; employ constant-speed, forced feeding to prevent the equipment from alternating between full and empty states, ensuring a stable extrusion rhythm and consistent compliance with production targets.
Clearing blockages and filter resistance
A filter screen that is too dense or clogged with debris will increase die pressure and slow down material discharge. Replace the screen with one of the appropriate mesh count as needed to reduce extrusion resistance.
Inspect the screw and barrel for wear.
Wear of the pin and excessive clearance in the screw can lead to reduced conveying thrust, slippage, and slow discharge; promptly inspect and repair wear‑prone components to restore the equipment’s extrusion pressure.
Traction Speed Matching Adjustment
An imbalance between extrusion speed and traction speed can cause material buildup and reduced production; when extrusion and traction parameters are properly synchronized, the production line operates at full speed with stable performance.
Pre-treatment of rubber compound
Excessive compound hardness, uneven mixing, and excessive cooling during storage can all increase extrusion load; preheating and ensuring uniform mixing reduce equipment load and improve extrusion efficiency.
