How to Choose a Feeder for Limestone 200 tph Quarry
For limestone quarries in Saudi Arabia and the UAE, selecting the right feeder for a 200 tph crushing line is critical to ensure even feed to the primary crusher, reduce maintenance downtime, and maximize throughput. A properly chosen feeder removes fines, protects the jaw crusher from oversized material, and maintains a choke‑fed condition. The question how to choose a feeder for limestone 200 tph quarry involves evaluating feeder type, size, and features. Below we explain the options and key selection criteria. OCP Mechanical Company supplies factory‑direct feeders for Gulf conditions, with local support and 24/7 online assistance.
Feeder Type: Vibrating Grizzly vs. Apron vs. Pan
The first decision in how to choose a feeder for limestone 200 tph quarry is the feeder type. For dry to moderately moist limestone, a vibrating grizzly feeder (Type F) is a widely used choice. It performs two functions: it meters material evenly and scalps out fines below the grizzly bar spacing (typically 80‑120 mm). Removing fines reduces jaw crusher wear and increases net capacity. For sticky or wet limestone (moisture >8%), a heavy‑duty apron feeder (Type A) with overlapping steel pans is a reliable option, though it has higher capital and operating costs. For most limestone quarries in the Gulf region, a vibrating grizzly feeder is the most economical and effective solution.

Many quarries in Riyadh and Dubai have increased jaw crusher throughput by 15‑25% after installing a vibrating grizzly feeder with proper bar spacing.
Sizing and Capacity Considerations
To correctly answer how to choose a feeder for limestone 200 tph quarry, you must size the feeder to match the crusher’s capacity and feed size. For a 200 tph limestone jaw crusher (e.g., Type J-900x1200), a feeder width of 1,000‑1,200 mm and length of 4,000‑5,000 mm is typical. The feeder’s capacity should be 10‑20% higher than the crusher’s rated capacity to account for surges. For limestone with bulk density of 1.6 t/m³, a feeder with a capacity of 220‑240 tph is recommended. The grizzly bar spacing should be set to 80‑100% of the jaw crusher’s CSS – this prevents oversize from entering the crusher and allows fines to bypass.

Key Features to Look For
When determining how to choose a feeder for limestone 200 tph quarry, focus on these practical features:
Grizzly bar material – Manganese or Hardox bars resist abrasion from limestone. Replaceable sections extend feeder life.
Drive system – Two unbalanced motors are standard; a variable frequency drive (VFD) allows speed adjustment to match crusher load, reducing energy use.
Liner plates – Hardox liners in the feed box protect against impact and abrasion.
Adjustable bar spacing – Allows you to change the scalping size if the crusher CSS changes later.
A feeder with a VFD can save 8‑12% on electricity while improving feeding consistency. Many operators in the UAE have adopted VFD‑equipped feeders for better control.
