Reciprocating Feeder
-
High Head-Load Endurance: Engineered to withstand massive static weight and high-impact dumping directly beneath large storage silos.
-
Mechanical Adjustability: Easily customizable stroke length and frequency to achieve precise control over volumetric flow rates.
-
Clog-Free Material Delivery: Smooth, linear reciprocating motion ensures reliable transport of sticky, wet, or oversized bulk solids.
-
Low Civil Engineering Footprint: Low-profile, compact structural frame drastically reduces the required excavation and headroom depth beneath hoppers.
1. Product Overview
Reciprocating feeder is a classic trough-type feeding equipment for mine primary crushing system. Driven by crank-link mechanism, the trough moves back and forth in a straight line. It is generally installed between raw ore bins and jaw crushers to convey large lump ores. Featuring stable feeding and strong impact resistance, it is widely used in stone aggregate and mineral processing production lines under heavy-load and dusty working conditions.
2. Detailed Description
The motor drives the crank-link mechanism through the reducer to convert rotary motion into horizontal reciprocating movement of the trough. When the trough moves forward, it pushes materials ahead; when moving backward, materials stay in place by inertia, realizing continuous feeding. The output capacity can be adjusted by changing eccentric stroke and rotating speed.
3. Why Choose Us
-
Crank reciprocating pushing, continuous stable feeding without surging: The tank reciprocates horizontally to push materials evenly, stable discharge flow, perfectly match feeding demand of primary jaw crushers.
-
Strong load capacity to bear silo pressure, suitable for large lump raw ore: Thick steel tank and heavy frame can be installed under silos directly, conveying large lump ore and raw coal under heavy stock pressure.
-
Suitable for wet & dry lumpy materials, effectively prevent silo bridging: Reciprocating push-pull disturbs materials continuously, wet sticky ore and muddy coal hardly cake or block silos, low failure rate.
-
Simple mechanical transmission structure, durable and easy maintenance: Driven by crank connecting rod with few vulnerable parts; openable housing for quick liner replacement, less maintenance downtime.
-
Low power consumption & low running noise, support long-term continuous operation: Mechanical pushing without high-frequency impact, lower power consumption under same throughput, fit 24h non-stop mining production.
-
Standard equipment for mine primary crushing, widely matched in multiple industries: Widely used under silos of coal mines, metal mines and aggregate plants, matched with jaw crushers and belt conveyors for underground & open-pit working conditions.
