Grizzly Screeners

Need heavy-duty scalping and screening equipment for mined minerals, coals, and aggregates?

Robust design with a reinforced pan and slotted grizzly bars

Separate fines prior to them reaching downstream crushers

Efficiently remove undersized rocks and dirt to reduce load on a primary crusher

Carrier Grizzly Screener

Built for the toughest bulk material handling applications, Carrier grizzly screeners provide controlled feeding and efficient scalping of oversized material before crushing and further screening or processing. Designed for heavy-duty operation, these screeners separate fines from larger material while delivering a consistent feed rate to downstream equipment.

Carrier grizzly machiness are engineered for reliability in abrasive, high-impact environments and are custom designed to meet the specific demands of mining, aggregates, minerals, recycling and industrial processing operations.

Features & Benefits

Robust welded steel construction withstands high-impact loading and abrasive materials for long service life in demanding applications.

Self-relieving bars with reinforced, narrowing, hardened steel (bear claw design) prevents oversized products from wedging and blocking the flow.

Customizable grizzly openings allow operators to control material sizing and separation based on process requirements.

Grizzly sections remove fines and undersized material before primary crushing, improving crusher efficiency and reducing wear.

Supported or suspended using durable steel coil or soft rubber isolation springs to prevent harmful vibrations from transferring to surrounding structures.

Consistent scalping rates help optimize downstream equipment performance and maintain process stability.

Vibration promotes continuous material flow and helps minimize buildup, bridging and plugging with difficult materials.

Simple mechanical design with fewer moving parts provides dependable operation and easier maintenance access.

Equipment Options & Accessories

Isolation Arrangements

Carrier offers several isolation configurations using steel coil or soft rubber isolation springs to isolate vibration from surrounding structures.

Replaceable Wear-Liners

Protect feeder surfaces from abrasion and extend equipment life in severe-duty applications.

Adjustable Grizzly Bars

Modify spacing to accommodate changing product sizing or application requirements.

Bearings

Bearings are custom designed and specially engineered for heavy-duty workload.

Discharge

Customizable with side, end, intermediate, straight, or bias discharges to suit your specific plant layout.

Custom Engineered Designs

Available in multiple sizes, configurations and drive arrangements to suit unique material characteristics and plant layouts.

Applications

Crushed Stone

Scalps oversized rock from crushed stone using heavy-duty grizzly bars and controlled vibration. High-capacity screening removes fines while maintaining consistent material flow to downstream crushing and sizing equipment.

Limestone

As raw limestone is dumped onto the machine, the vibrations convey the rock forward while strategically spaced grizzly bars scalp off oversized boulders into the primary crusher, allowing smaller material to bypass the crusher entirely. Robust grizzly decks withstand heavy impact loads while vibration promotes consistent material stratification and throughput.

Granite

Handles abrasive, high-density granite with rugged grizzly bars engineered for demanding duty. Controlled vibration efficiently removes undersized material while directing oversized rock to downstream crushing equipment.

Bauxite

Scalps fines and separates oversized bauxite prior to crushing or material handling. Vibratory action maintains consistent feed distribution while heavy-duty grizzly construction withstands abrasive mineral processing conditions.

Coal

Removes fines and separates oversized coal before crushing, conveying, or further classification. Controlled vibration promotes material stratification and reliable throughput while reducing unnecessary loading on downstream equipment.

Sand & Aggregates

Provides high-capacity scalping of aggregate feed streams by removing fines and oversized material. Vibratory motion improves material distribution and separation efficiency before crushing, washing, or secondary screening.

Ores

Pre-screens mined ores to remove fines and control top-size material before crushing. Heavy-duty construction accommodates high-impact loads while vibration maintains consistent feed rates and efficient separation. Raw, run-of-mine (ROM) ore dumped from haul trucks impacts the feeder’s heavy-duty feed pan. The pan can be lined with impact-absorbing materials to prevent structural damage and handle massive headloads.

Recycled Concrete & Asphalt

Scalps oversized debris and fines from recycled concrete and asphalt streams. Rugged grizzly decks handle irregular material while maintaining controlled feed to crushers and downstream recycling equipment.

Scrap Metals

Separates oversized scrap and fines from mixed metal streams using robust grizzly decks. Controlled vibration promotes consistent material movement while handling heavy, irregular, and high-impact feed materials.

Glass Cullet

Screens glass cullet to remove oversized pieces and fines before further processing. Controlled vibratory action provides consistent material distribution while durable deck construction accommodates abrasive recycled glass.

Foundry Materials

Scalps sand, castings, and other foundry materials to separate fines and oversized fractions. Heavy-duty vibration supports consistent material flow while withstanding abrasive, high-temperature, and impact-intensive operating conditions.

Grizzly Screeners FAQs

What is the purpose of a grizzly screener?

A grizzly screener/scalper is designed to scalp bulk material at a controlled rate while simultaneously separating fines and undersized material before primary crushing or downstream processing equipment.

What types of materials can a Carrier grizzly screener handle?

Carrier grizzly screeners are built to handle abrasive and heavy bulk materials such as aggregates, coal, ores, slag, recycled concrete, minerals, wood waste and other coarse industrial materials.

Can grizzly bar spacing be customized?

Yes. Grizzly bar openings can be customized and adjusted to achieve the desired material separation and scalping performance for specific applications.

How does a grizzly screener improve crusher performance?

By removing fines before material reaches the crusher, the screener helps reduce unnecessary crushing loads, minimizes wear on crushing equipment and improves overall plant efficiency.

Are Carrier grizzly screeners designed for heavy-duty continuous operation?

Yes. Carrier grizzly screeners are engineered for rugged, continuous-duty operation in demanding processing environments with durable construction and reliable vibratory drive systems.
