Need mobile crushing plant for gypsum 128 tph in Pakistan

For gypsum mining and processing in Pakistan’s major producing regions – including the districts of Dera Ghazi Khan, Sukkur, and Kohat – a 128 tph mobile crushing plant offers a flexible, cost‑effective solution to reduce run‑of‑mine gypsum to a manageable size for cement, plaster, and agricultural applications. Gypsum is soft (Mohs 2‑3) but can be abrasive when associated with clay or anhydrite. A mobile plant eliminates the need for permanent foundations and can be moved between mining faces, reducing haulage costs. When you need mobile crushing plant for gypsum 128 tph in Pakistan, a single‑stage impact crusher plant is a widely used choice. OCP Mechanical Company, a factory‑direct manufacturer with over 40 years of experience, supplies Type M‑G128 mobile crushing plants designed for soft industrial minerals, backed by 24/7 online support.

Why a mobile impact crusher is a practical choice for gypsum

Gypsum is soft and friable. An impact crusher (Type I-128) with a 160‑200 kW motor, two breaker curtains, and reversible blow bars can accept feed up to 400‑500 mm and produce 120‑140 tph of 0‑40 mm or 0‑20 mm product in a single pass. The high reduction ratio (up to 15:1) allows a single impact crusher to replace a jaw‑cone circuit, saving capital and maintenance costs. Many Pakistani gypsum mines have successfully used mobile impact crushers of this size, reporting consistent output and blow bar life of 500‑800 hours with Cr20% alloy due to the material’s low abrasiveness. For gypsum containing hard anhydrite or clay nodules, upgrading to Cr26% blow bars adds 30‑50% longer life.

Key features that lower your cost per ton of gypsum

When you evaluate a mobile crushing plant for gypsum, focus on features that directly reduce operating expenses:

• Reversible blow bars – Cr20% chrome iron is a widely used choice. Reversible bars can be flipped to use both edges, extending life by up to 30%.

• Hydraulic curtain adjustment – Allows product size changes in minutes without stopping the crusher, a valuable advantage for producing multiple grades.

• Variable frequency drive (VFD) – Saves 8‑12% on electricity by matching rotor speed to feed conditions. For gypsum, a rotor speed of 400‑500 rpm is typical.

• Heavy‑duty rotor – Ensures consistent crushing force even with variable feed.

• Dust suppression system – Gypsum dust can be fine; water sprays or a bag filter help meet local environmental standards.

• Magnetic separator (optional) – Removes tramp metal that may be present in gypsum from blasting.

A mobile impact crusher plant for 128 tph (wheeled chassis, without generator) ex‑works ranges from $130,000 to $200,000 USD. A track‑mounted version adds $30,000‑$50,000. A diesel generator (350 kVA) adds $20,000‑$35,000. Shipping to Karachi or Port Qasim (CIF) adds $10,000‑$18,000. Total landed cost is approximately $160,000‑$270,000 USD.

How to optimize the mobile plant for gypsum crushing in Pakistan

To get the most from your mobile crushing plant, follow these operational tips:

• Set curtain gaps – For a typical 0‑30 mm product (for cement plant feed), set the primary curtain gap to 20‑30 mm and the secondary curtain to 10‑15 mm. For a coarser product (0‑50 mm for road base), widen the gaps.

• Adjust rotor speed – Start at 450 rpm. If the product is too coarse, increase speed by 20 rpm; if too many fines, decrease speed.

• Remove fines before the crusher – Use the on‑board vibrating grizzly feeder to scalp out material below 10‑15 mm. This reduces blow bar wear and increases net throughput.

• Maintain choke‑fed condition – A full crushing chamber ensures even blow bar wear and consistent product shape.

• Rotate blow bars every 200‑250 hours – Even though wear is low, rotation extends life further.

Many Pakistani gypsum producers have achieved 128 tph consistently with blow bar life exceeding 600 hours.

Price range and return on investment in Pakistan

Operating costs: blow bars at $0.01‑$0.03 per ton, electricity at $0.06‑$0.08 per ton (or diesel at $0.10‑$0.15 per ton). At 128 tph for 2,500 hours/year (320,000 tons), annual operating cost is $10,000‑$20,000. Selling crushed gypsum for cement production at $5‑$10 per ton generates $1.6‑$3.2 million in annual revenue, providing a rapid payback often within 6‑12 months.
