Multi-cylinder cone crusher The crushing efficiency is the highest. lts short and thick main shaft and frame direct support design make the crushing force stronger, lt is suitable for processing high hardness and high abrasive materials, The crushing efficiency is the highest among the three types. Single cylinder cone crusher It is suitable for materials with medium to high hardness, such as granite, basalt, etc. Lts hydraulic system can adjust the discharge port according to the hardness of the material, thus adapting to materials of different hardness. Multi-cylinder cone crusher It is suitable for materials with high hardness and high abrasiveness. its powerful crushing force and frame design enable it to perform well in processing these materials. Single cylinder cone crusher The ratio of energy consumption to production capacity is low, and its hydraulic system can achieve precise adjustment of the discharge opening, thereby increasing production capacity. At the same time, the energy consumption is relatively low, which is suitable for occasions with high requirements on energy consumption and production capacity.

Our topic today is Comparative Analysis of Single-cylinder and Multi-cylinder cone crushers. 01-Overview of Equipment Cone crusher basic definition How it works Cone crusher squeezes and crushes materials into required particle size through the relative movement between the movable cone and the fixed cone. it is widely used in medium and fine crushing operations in mining, metallurgy, construction and other industries. Core components It mainly includes frame, transmission device, eccentric sleeve, movable cone, fixed cone, hydraulic system, etc. All components work together to achieve efficient crushing. Applicable materials Cone crusher is particularly suitable for processing medium-hard and hard ores,such as granite, basalt, iron ore, etc., and can achieve efficient and stable crushing effect. 02-Core Structure Differences Single cylinder/multi-cylinder structure classification standard Differences in hydraulic systems: Single-cylinder hydraulic cone crushers use a single-cylinder hydraulic system,...

1. Working principle of cone crusher Cone crushers crush materials through the swinging motion of the moving cone inside the fixed cone, subjecting materials to continuous extrusion, bending, and shearing. Classified by cavity type: standard (medium crushing), medium (medium-fine), and short head (fine crushing), suitable for medium and fine crushing of hard rocks. 2. Hydraulic system and intelligent control function Hydraulic systems of modern cone crushers have multiple functions: – Overload protection: Hydraulic cylinders retract automatically when encountering uncrushable materials – Auto chamber clearing: Raise the moving cone via hydraulics to remove jams quickly. – Auto discharge adjustment: PLC system adjusts hydraulic pressure in real-time based on feeding to stabilize output size. 3. Selection comparison and application scenarios Selection recommendations: – Jaw crusher: For primary crushing of large materials, low initial investment. – Impact crusher: For medium crushing and shaping, good product shape, suitable for construction stone. – Cone crusher: For fine crushing of hard rocks, long wear life, suitable for large mines with continuous operation. 4. Maintenance points – Regularly inspect the eccentric bushing wear of cone crusher, recommend disassembly every 500 hours. – Replace hydraulic oil every 3000 hours, cleaning the tank and filter when replacing. – Check...

1. Working principle and characteristics of impact crusher Impact crushers break materials by throwing them onto impact plates via a high-speed rotor (600-1000r/min). Materials repeatedly strike between the rotor and impact plates to form the desired particle size. It features good product shape and low flakiness, suitable for medium crushing and shaping, such as highway aggregate production. 2. Selection of core components and wear-resistant materials – Hammers: Recommend high-chromium cast iron (Cr20-Cr28), hardness HRC58-62, lasting about 300 hours in granite crushing. – Impact plates: Use Mn13 high-manganese steel, which hardens with impact to improve wear resistance. – Rotor assembly: Regularly check balance to avoid abnormal vibration due to wear. 3. Process parameter adjustment method – Rotor to impact plate gap: Usually 10-30mm—reducing from 20mm to 15mm increases 0-10mm particles by 12%. – Rotor linear speed: Optimal for PF1315 is 25-28m/s—too high increases powder, too low reduces efficiency. – Uniform feeding: Ensure materials enter the chamber evenly to avoid uneven wear. 4. Common faults and solutions – Abnormal hammer wear: Check for metal impurities in feed or excessive rotor speed. – Oversized output: May be due to large impact plate gap or severe hammer wear—adjust or replace promptly. – Increased vibration:...

The basic structure and working principle of jaw crusher Jaw crushers consist of a moving jaw, fixed jaw, eccentric shaft, toggle plate, and frame. During operation, the eccentric shaft drives the moving jaw in reciprocating motion, and the V-shaped crushing chamber formed with the fixed jaw crushes materials through extrusion and splitting. This equipment is suitable for ores with compressive strength below 300MPa, such as granite and limestone, mainly used in the primary crushing stage. Key parameters for choosing jaw crusher: – Feed opening size: Expressed as length × width, e.g., PE600×900 can accommodate materials up to 500mm; – Processing capacity: Varies by model, e.g., PE900×1200 jaw crusher processes 150-280 tons of granite per hour; – Discharge opening adjustment range: Typically 20-300mm—reducing it gives finer output but lowers efficiency. Key points of operation and maintenance of jaw crusher Operation and maintenance tips: – Liner replacement: Loosen tie rod bolts first, use hydraulic system to retract the moving jaw; install new liners in a staggered pattern. – Jam handling: Do not force-start the motor if jammed. Cut off feeding, check for oversized materials or metal, and use the hydraulic clearing system. – Lubrication: Regularly inspect the lubrication of eccentric shaft bearings;...

Ordinary jaw crushers and European jaw crushers have their own characteristics and are suitable for different scenarios. It is impossible to simply judge which one is better. The following is a main comparison between the two: 1. Structural design The structural design of ordinary jaw crushers is relatively traditional. The bearing seat and the frame are usually welded, and the overall stability is relatively weak. Under long-term high-intensity operation, problems such as cracking of the welding parts may occur, which will affect the service life of the equipment. The European version of the jaw crusher adopts a non-welded integrated frame and an integral cast steel structure, which can withstand greater impact and vibration, and has significantly enhanced stability and durability. At the same time, the larger eccentric shaft and higher-specification bearing design increase the load-bearing capacity of the equipment and extend its service life. 2. Feeding and crushing chamber Generally, the jaw crusher adopts a semi-V-shaped or oblique V-shaped crushing chamber. The width of the feeding port is relatively narrow, and the ability to handle large-sized raw materials is limited. The flow path of the material in the crushing chamber is not optimized, which is prone to blockage and affects...
