Vibrating Feeders

GNR Vibrating Grizzly Rock Feeder: 75-600 tph Primary Crusher Feeding

Vibrating Grizzly Feeder: Steady Primary Feeding with By-Pass Pre-Scalping

The GNR vibrating grizzly rock feeder delivers run-of-mine rock up to 1500 mm to the primary crusher at 75-600 tph in a steady flow. Its grizzly by-pass section removes fines and soil before they reach the crusher. Available with vibromotor or eccentric drive, the GNR 60/90/110/140 models keep the crusher mouth choke-fed.

Vibrating Sand Feeder (Bin Feeder) | General Makina

Vibrating Bin Feeder for Processed Sand and Aggregate

A vibrating sand feeder is a vibrating bin that stockpiles processed sand, chippings and aggregate off the ground in a 25-100 m³ hopper and feeds it to a conveyor, screen or truck at a steady, dosed rate. It accepts up to 200 mm feed and ensures uninterrupted flow at wash-and-screen outlets and concrete-plant aggregate lines.

Wobbler Feeder (Elliptical Shaft Feeder) | General Makina

Wobbler Feeder with Elliptical Shafts for Wet, Clayey Feed

The wobbler feeder uses synchronized rotating elliptical disc shafts to feed wet, clayey and sticky run-of-mine material to the crusher without blinding, while separating fine mud and soil. Driven by a geared motor (motor-gearbox-chain), it runs quiet and vibration-free. The GWB1136 model delivers 75-600 tph. A critical solution where grizzly feeders fail in wet conditions.

Vibrating feeders are the plant's inlet equipment, delivering ROM feed from the hopper to the primary crusher at a steady, choke-free, controlled rate. Correct feeding directly sets crusher efficiency and the tonnage of the whole line.

Feeder types

The grizzly rock feeder (75–600 tph) conveys coarse material while separating fines/soil through the grizzly bars, protecting the crusher from needless load — a pre-screening function. The sand bunker feeder gives a steady flow of fine material. The wobbler feeder (stepped elliptical shafts) pre-separates sticky, clayey, wet material while avoiding blockage.

Selection logic

For coarse, soily material use the grizzly; for a fine sand flow, the bunker feeder; for clayey-wet, sticky material, the wobbler. Sizing follows capacity, feed size and material character.

Full-plant bridge
