45220 Straight Throwing Board Ejector for W150 W1000 Milling Drum

The throwing board (ejector) is bolted onto the milling drum tube. As the drum rotates, it scoops up milled asphalt or concrete material and propels it upward into the discharge conveyor. Worn ejectors reduce material transfer efficiency, causing buildup in the drum housing, increased conveyor wear, and lower loading capacity.

We offer express delivery (5-7 days), air freight (7-15 days), and sea freight (30-45 days). Bulk orders are packed in consolidated cartons to reduce shipping cost.

Our professional after-sales and technical team responds to all customer inquiries within 5 minutes during working hours. For any issue related to throwing board compatibility, installation guidance, bolt torque, or product quality, we commit to providing a complete solution within 48 hours, including technical documentation, video-guided support, rapid replacement, or refund assistance. We understand that milling machine downtime directly impacts your project schedule.

Replace the throwing boards when you observe any of these signs: the working edge is worn down significantly, the board is cracked or bent, bolt holes are elongated, material is falling back into the drum housing during operation, or loading capacity has noticeably decreased. We recommend inspecting ejectors every 100-150 operating hours and replacing the full set on the drum simultaneously for balanced performance. Typical service life is 800-1,200 hours depending on material type.

The MOQ is 1 piece. Throwing boards are typically in stock and ship within 5-7 working days after payment confirmation. We offer a 6-month warranty against manufacturing defects, including material flaws, improper heat treatment, and dimensional non-conformity. For bulk orders (20+ pieces), we provide discounted pricing. We recommend keeping a full drum set of spare ejectors per machine for routine maintenance.
