Feeder grizzly price for heavy overburden 158 tph in Indonesia

For mining and quarry operations in Indonesia – from the coal mines of East Kalimantan to the gold and copper sites in Papua and the nickel laterite operations in Sulawesi – heavy overburden removal is the first challenge. A vibrating grizzly feeder (VGF) designed for heavy overburden must handle large, abrasive, sometimes sticky material at 158 tph while protecting the primary crusher. Knowing the feeder grizzly price for heavy overburden 158 tph in Indonesia helps you budget for a robust unit that reduces crusher wear, improves throughput, and lowers operating costs. OCP Mechanical Company, a factory‑direct manufacturer with over 40 years of experience, supplies Type F‑HD (heavy duty) grizzly feeders engineered for Indonesian overburden conditions, backed by local support in Jakarta and 24/7 online assistance.

Why a heavy‑duty grizzly feeder is essential for overburden

Overburden in Indonesia can contain boulders up to 600‑800 mm, clay, moisture, and sharp fragments. A standard feeder may bend grizzly bars or suffer from accelerated pan wear. A heavy‑duty grizzly feeder for 158 tph incorporates thicker deck plates, reinforced sidewalls, and oversize exciter bearings. Its primary functions are to scalp out fines (typically below 100‑150 mm) and to feed the jaw crusher evenly, reducing crusher wear by 20‑30% and increasing net throughput by 15‑20%. Many Indonesian mining operations have switched to heavy‑duty feeders, reporting longer service life and reduced unscheduled downtime.

Key features that affect the price of a 158 tph heavy overburden feeder

The feeder grizzly price for heavy overburden 158 tph in Indonesia depends on several factors:

• Feeder size – Width of 1,500‑1,800 mm, length 5,000‑6,500 mm. Larger dimensions increase capacity and cost.

• Grizzly bar type – Bolt‑on, adjustable manganese or Hardox bars with tapered profiles (spacing 120‑200 mm). Heavy‑duty bars cost 20‑30% more than standard.

• Liner material – Hardox 500 or ceramic liners in the feed box and under the grizzly section add 15‑25% but last 2‑3 times longer than mild steel.

• Drive system – Two heavy‑duty unbalanced motors (15‑30 kW each) are standard. A variable frequency drive (VFD) adds $4,000‑$8,000 for speed control and soft start.

• Vibration isolation – Rubber coil springs (quieter, moderate cost) or steel springs (less expensive but noisier).

A Type F-HD feeder (1,600 x 6,000 mm) with Hardox liners and heavy‑duty motors ex‑works typically ranges from $35,000to$65,000 USD. Shipping to Jakarta or Surabaya (CIF) adds $6,000‑$12,000. A starter set of grizzly bars, vibrator motor bearings, and V‑belts adds $3,000‑$5,000. Total landed cost is approximately $45,000‑$85,000 USD.

How to select the right feeder for your overburden operation

To get an accurate feeder grizzly price for heavy overburden 158 tph in Indonesia, provide OCP’s engineers with your material characteristics: maximum lump size (e.g., 700 mm), clay content, moisture level, and required throughput (158 tph). For overburden with many boulders, grizzly bar spacing of 150‑200 mm is recommended. For material with high fines content, spacing of 100‑150 mm helps scalp more waste before the crusher. Choose a feeder width at least 1.2 times the jaw crusher width to ensure even distribution. A VFD is highly recommended – it allows soft start to reduce impact on the crusher and adjusts feed rate to match crusher load. OCP offers a free material test on your overburden sample to recommend the optimal grizzly bar spacing and liner configuration.

Installation and maintenance tips for Indonesian conditions

Indonesia’s tropical climate (high humidity, heavy rainfall) requires special attention. Install the feeder on a reinforced concrete foundation with vibration isolation springs to prevent settling in wet ground. Ensure the feeder is level and properly aligned with the crusher. For sticky overburden, a water spray system at the grizzly bars helps prevent clay buildup. Lubricate exciter bearings every 200 hours with high‑temperature grease (appropriate for 40°C+ ambient). Keep a spare set of grizzly bars, springs, and motor bearings on site – shipping from overseas can take 4‑6 weeks. Clean the grizzly bars with a water lance at the end of each shift to prevent dried material from caking. For extremely abrasive overburden, consider Hardox or ceramic liners to extend feeder pan life.
