In the fields of mining, construction aggregates and solid waste resource utilization, the particle shape uniformity, production efficiency and equipment adaptability of material crushing have become core competitive indicators. Traditional cone crushers are difficult to meet the dynamic needs of multiple scenarios due to problems such as fixed cavity type and limited particle size adjustment range. In response to this challenge, the CS series multi-cavity high-efficiency cone crusher has redefined the flexibility of medium and fine crushing processes through modular cavity design and intelligent particle size control technology, becoming an innovative benchmark in the field of crushing equipment.
1. Design concept and technological breakthrough of multi-cavity CS high-efficiency cone crusher
The multi-cavity design of the CS series is based on the concept of "one machine for multiple uses" and realizes rapid replacement of the cavity through standardized interfaces. Its core components include:
Removable liner group: Provides three basic cavity types (C1/C2/C3) of coarse, medium and fine, and users can flexibly choose according to material hardness (Praeter coefficient f=6-16) and target particle size (12-45mm).
Dynamic adjustment mechanism: The hydraulically driven eccentric sleeve works in conjunction with the main shaft assembly to allow fine-tuning of the crushing ratio within the range of ±15%, and can adapt to material changes without stopping.
Intelligent compensation system: Real-time monitoring of liner wear, automatic compensation of the discharge port gap through the hydraulic cylinder, and ensuring that the discharge stability error is ≤3%.
To achieve precise particle size management, the CS series integrates three innovative technologies:
Laminated crushing optimization algorithm
Through finite element analysis (FEA) to simulate the movement trajectory of the material in the cavity, optimize the swing frequency (280-350 rpm) and stroke (40-60 mm) of the moving cone, and reduce the proportion of needle-like particles to <10% (about 15-20% for traditional equipment).
Hydraulic-sensing collaborative system
Equipped with a pressure sensor and a PLC controller, when an overload or foreign object intrusion is detected, the hydraulic system can automatically lift the moving cone within 0.5 seconds to discharge unbreakable objects, reducing the failure rate by 60%.
Multi-stage screening feedback mechanism
Linked with the downstream vibrating screen, the discharge port is dynamically adjusted according to the proportion of the screened material to form a closed-loop control to ensure that the qualified rate of finished products is ≥95%.
2. Practical application scenarios and benefit analysis of multi-cavity configuration
Mine crushing: efficient adaptation from granite to iron ore
Take a large granite aggregate project as an example (capacity requirement: 250 t/h, finished product specification 0-25mm):
Coarse crushing stage: Select C1 cavity type (feed port size 190mm), with large eccentricity, to crush the raw ore (particle size ≤500mm) to 80-120mm.
Fine crushing stage: Switch to C3 cavity type (discharge port preset 12mm), combined with high swing frequency mode, to produce rounded 5-25mm aggregate, with a needle-like content of only 8.3%.
Economic benefits: Compared with fixed cavity equipment, the energy consumption per ton is reduced by 18%, and the liner life is extended to 8000 hours (conventional 6000 hours).
Construction waste resource utilization: flexible response to complex components
In a construction waste recycling project (including concrete blocks, bricks, tiles, steel bars and other impurities):
Pre-screening stage: electromagnetic iron remover is used to separate metals, and large pieces of concrete enter the CS crusher.
Multi-chamber strategy:
The primary crushing uses C2 chamber type (discharge port 35mm) to quickly process large pieces of materials;
The secondary crushing switches to C3 chamber type (discharge port 15mm), and the hydraulic chamber cleaning function is used to prevent steel bar entanglement.
Result indicators: The crushing value of recycled aggregate is ≤12%, and the impurity rate is <1%, which fully complies with the GB/T 25177-2010 standard.
3.Equipment operation and maintenance and sustainable design
Improved maintenance convenience
Modular disassembly and assembly: The core components such as the moving cone assembly and eccentric sleeve are connected by flanges, and the replacement time is shortened to 4 hours (traditional models require 8-12 hours).
Online monitoring platform: Through sensors such as vibration, temperature, and oil particle size, fault warning and life prediction are achieved, and maintenance costs are reduced by 30%.
Green production and energy consumption optimization
Energy-saving design: The power of the main motor matches the crushing load, and the power consumption in standby mode decreases by 40%;
Dust control: Labyrinth seal + positive pressure dust prevention system, dust concentration in the working area ≤5mg/m³ (national standard requirement ≤10mg/m³);
Resource recycling: The liner is made of high-chromium cast iron (Cr content 26-28%), which can be recycled after wear, and the material utilization rate reaches 90%.
The multi-cavity CS high-efficiency cone crusher breaks through the rigid limitations of traditional equipment through structural innovation and technological integration, and provides a more efficient and economical solution for sand and gravel aggregates, metal mines and solid waste recycling. Its "flexible particle size control" is not only a technical parameter, but also a deep response to the core needs of users, marking that crushing equipment has officially entered the era of intelligence and customization.
