Tertiary crushers, also known as "sand machines" in mining and aggregate plants, are high-speed impact crushers designed to produce high-quality sand by reducing materials down to 0-5 mm sizes. Medium-hardness materials that pass through Primary and Secondary crushers or remain over the screen without reaching the desired fineness are fed into tertiary crushers, which represent the third crushing stage.
Thanks to their high-speed rotor structure, they enable an average of 40% to 60% 0-5 mm sand yield from the processed rock. At the same time, they keep the unwanted dust ratio to a minimum, offering high product cubicity and maximum profit margins for businesses.
Tertiary Crusher Manufacturing and Technical Features
Tertiary crusher manufacturing is carried out in different models with 160 kW to 250 kW motor power and 700 to 1000 rpm rotor speeds, depending on the required hourly capacity and crushing difficulty. Their technical advantages offering high performance and low operating costs include:
- Reversible Rotor Design: Thanks to the rotor's ability to rotate in both directions, both sides of the hammers are used symmetrically. This doubles the hammer lifespan and reduces wear costs.
- Easy Maintenance and Adjustment Mechanism: Body covers that open hydraulically or mechanically to both sides allow hammer replacement, periodic maintenance, and lubrication operations to be carried out extremely fast and safely.
- Wide Feed Size: It has the capability to handle feed sizes up to 80 mm for river stones and up to 150 mm for quarry stones.
- Application Areas: Widely preferred in ready-mix concrete plants, asphalt plants, and sand-gravel quarries that require highly cubic products and sand.
Factors Affecting Tertiary Crusher Prices
When evaluating tertiary crusher prices for an enterprise, the focus should not only be on the initial purchase cost, but also on the long-term performance and spare part durability of the plant. The main factors directly determining pricing are:
- Motor Power and Rotor Speed: The motor power and rotor weight used depending on the hourly tonnage capacity of the crusher.
- Wear-Resistant Parts: The quality of high-manganese and high-chromium alloys used in hammers and interior liner plates.
- Plant Structure: Positioning the crusher on a mobile chassis or a stationary steel structure.
- Service and Logistics: Transportation, ease of installation, uninterrupted spare parts supply, and post-sales technical support opportunities.
The Right Solution for High Sand Yield
Having a high-quality sand machine that will operate uninterruptedly for many years under heavy field conditions is the most effective way to reduce your production cost per ton.
