NEO MAKİNA ve MÜHENDİSLİK A.Ş. designs and manufactures industrial crusher systems for size reduction of rock, ore, coal, limestone and industrial raw materials. Jaw crushers for primary crushing, impact and cone crushers for secondary and tertiary stages, hammer and roll crushers for fine crushing are delivered as complete lines with feeders, screens and conveyors for mining, aggregate, cement, lime, coal-preparation and recycling plants.
Crusher Types and Crushing Principles
Jaw Crushers: Primary Crushing
- Principle: Compression between fixed and moving jaws; reduction ratio 4:1 – 6:1.
- Application: Hard, abrasive rock such as granite, basalt, quartzite (compressive strength up to 300 MPa); feed size up to 1,000 mm.
- Construction: High-manganese (Mn 18) cast jaw plates, heavy-duty welded frame, hydraulic adjustment and overload protection.
- Capacity: 20 – 800 t/h.
Impact Crushers: Cubic Product
- Principle: High-speed rotor blow bars strike the material and throw it against breaker plates (aprons); reduction ratio 10:1 – 20:1.
- Application: Cubic aggregate from medium-hard materials such as limestone, dolomite, concrete and asphalt recycling.
- Types: Horizontal-shaft (HSI) secondary/tertiary; vertical-shaft (VSI) for sand production and shaping.
- Capacity: 30 – 600 t/h.
Cone Crushers: Secondary and Tertiary
- High-capacity secondary/tertiary crushing of hard, abrasive material; hydraulic setting, low wear cost; 50 – 1,000 t/h.
Hammer Crushers: Fine Crushing
- Principle: Freely swinging hammers strike at high speed; bottom grate discharges product below target size; reduction ratio up to 20:1.
- Application: Brittle and medium-hard materials such as coal, limestone, gypsum, salt, glass, clay; cement and lime kiln feed, coal preparation.
- Types: Single and double rotor; reversible rotor doubles hammer life.
- Capacity: 5 – 300 t/h.
Roll and Sinter Crushers
- Double-roll crushers give controlled sizing of coal, coke, clay and soft ores; toothed rolls run blockage-free on sticky material. Special versions for hot material (sinter, clinker).
Engineering and Selection Criteria
- Material analysis: Compressive strength, abrasion index (Ai), moisture, clay content, feed size and target product curve.
- Circuit design: Open or closed circuit, number of stages, screen integration and bypass; mass-balance and product-curve simulation.
- Wear management: Manganese steel, chrome cast and ceramic-reinforced wear parts; replaceable liners.
- Drive and control: High starting-torque motors, fluid coupling or variable-frequency drive; overload and tramp-metal protection, vibration and temperature monitoring.
- Dust and noise: Enclosed chutes, water spray or dust-collection filter (Dust Collection Systems); acoustic enclosures.
Typical Application Range
- Capacity: 5 – 1,000 t/h (by crusher type)
- Feed size: up to 1,000 mm; product: 0–5 mm to 0–150 mm
- Sectors: quarrying and aggregates, mining, cement and lime, coal preparation and power plants, fertiliser, glass, recycling (concrete, asphalt, slag)
- Standards: CE Machinery Directive, EN 1009 (mineral processing machinery safety)
Why NEO MAKİNA?
Crushers are engineered as part of the complete crushing-screening plant; feeder, screen, conveyor, dust collection and automation are installed from a single source. Capacity upgrades, crusher replacement and wear-part supply are provided for existing plants. For complete plants see Crushing and Screening Plants and Mineral Crushing and Screening Plants.
Frequently Asked Questions
Jaw or impact crusher?
Jaw for primary crushing of hard, abrasive rock; impact for cubic product and high reduction ratio on medium-hard material. Most plants use both in sequence.
How can wear-part cost be reduced?
Correct crusher type and reduction ratio, feed-size control, suitable wear materials (Mn, Cr, ceramic) and regular gap adjustment lower wear cost per tonne.
Which crusher for coal?
Double-roll or hammer crushers for coal preparation and boiler feed; a mill is used before pulverised firing. For firing systems see ML34 MULTIBURN™.
