Crusher Feeder

Name: Feeder
Brand: Mohammadi Machine Industries

The Mohammadi crusher feeder receives bulk rock or mineral material and delivers it to the next machine at a controlled, uniform rate. Vibrating and grizzly configurations can stabilize crusher loading, reduce feed fluctuations and, where required, remove a portion of undersize material before primary crushing.

Technical Product Overview

What is a crusher feeder and why is it important?

The feeder is the controlled connection between the receiving hopper and the jaw crusher or another downstream machine. Instead of allowing the full hopper load to fall directly into the crusher, it meters the flow to keep the chamber consistently loaded and protect the line from sudden surges.

A grizzly feeder can also separate selected fines before crushing. This reduces unnecessary crusher load when the natural undersize does not need primary reduction. The correct design depends on maximum lump size, bulk density, moisture, clay, capacity, hopper geometry and downstream opening.

A feeder should be sized for both the largest lump and the required tonnes per hour. Capacity alone is not enough if the deck, hopper opening or grizzly spacing cannot handle the actual feed.

Primary Crusher FeedingDelivers a controlled flow to jaw, impact or other primary crushing equipment.

Hopper DischargeRegulates material leaving truck-fed or loader-fed receiving hoppers.

Pre-ScreeningA grizzly section can remove selected fines before the crusher.

Heavy Rock HandlingRobust configurations receive large, abrasive feed in quarry and mining lines.

Key Advantages

Main advantages of a crusher feeder

The feeder, hopper and crusher inlet must be designed together to obtain steady production and avoid bridging or overloading.

Regulated Flow

Controls the feed rate and reduces sudden load changes at the crusher.

Robust Deck

Structure and wear surfaces are selected for impact, lump size and abrasion.

Grizzly Option

Parallel bars can bypass selected undersize before primary crushing.

Process Matching

Dimensions, drive and discharge are coordinated with hopper and crusher capacity.

Operating Process

How does a vibrating or grizzly feeder work?

Material from the hopper rests on the feeder deck. The vibration system advances it toward the discharge at a controlled rate. In a grizzly configuration, particles smaller than the bar spacing pass through while larger rock continues to the crusher inlet.

Material ReceptionThe hopper delivers bulk feed onto the impact-resistant feeder deck.

Controlled MovementVibration advances material at a rate matched to downstream demand.

Optional Grizzly SeparationSelected fines pass between the bars before reaching the crusher.

Uniform DischargeRemaining material enters the crusher or conveyor in a controlled stream.

Project-Specific Configuration

Technical specifications and options for crusher feeders

Final dimensions and drive selection are based on hopper loading, maximum feed, material behavior, required capacity and downstream equipment.

Deck and Grizzly: Solid deck, lined section and optional bar spacing selected for the feed
Drive System: Vibration mechanism and motor sized for load and operating duty
Wear Protection: Replaceable liners or wear surfaces at high-impact locations
Installation and Control: Mounting, hopper interface and speed control arranged for the project

Selection and Purchase Guide

What should be specified before ordering a crusher feeder?

Hopper, feeder and crusher data should be submitted together so the entire loading system can operate without restriction.

Feed Characteristics

Define maximum lump, bulk density, moisture, clay and abrasiveness.

Required Rate

Provide normal, peak and minimum controllable feed rates.

Pre-Screening Need

State whether natural fines should bypass the primary crusher.

Hopper and Crusher

Provide opening sizes, elevations, loading method and interface dimensions.

Maintenance and Operation

How to maintain a crusher feeder

Regular inspection of the vibration system, wear liners, supports and grizzly bars helps preserve a uniform feed rate and prevents structural damage.

Inspect drive components, bearings and lubrication points

Check springs, mounts, fasteners and structural connections

Monitor deck liners and grizzly bars for wear or damage

Remove lodged rock safely and keep the discharge path clear

Verify feed-rate control and avoid prolonged hopper overloading

Frequently Asked Questions

Frequently Asked Questions About Crusher Feeder

Concise answers to important questions about selection, operation, maintenance and quotation.

It regulates material flow, reduces sudden load changes and helps keep the crusher operating within a stable feed range.

Both meter material by vibration, but a grizzly feeder also uses spaced bars to remove selected undersize before the crusher.

Capacity is matched to the downstream crusher while accounting for bulk density, maximum lump size, moisture, hopper pressure and controllable feed range.

A suitable control arrangement can be specified to regulate feed rate within the safe operating range of the selected feeder and process line.

Type, dimensions, capacity, maximum feed size, drive system, grizzly arrangement, wear liners, supports and controls determine the price.
