Jaw crusher model 1400

Product Name:Jaw crusher 1400
Model number explanation:"1400" refers to itsThe feed inlet width reaches 1400 mm.(e.g., 1400×1800mm and above), belonging to jaw crushersExtra-large, mining-grade specificationsThe original design intention was to handlePrimary ore with extremely high compressive strength。
Core positioning warning:In the context of a plastic crushing and washing line, a jaw crusher of type 1400 should be considered.It's almost an engineering paradoxIt may only exist inExtreme theoretical assumptionsorThere is a serious misunderstanding of material properties and process requirements.In the scene.

I. Hypothetical Functions and Almost Non-existent Application Scenarios

In the reality of plastic recycling, there are almost no economic or technical reasons to justify the use of this equipment. Its hypothetical function is based on the forced conversion of mining equipment:

1. The ultimate attempt at "indestructible" materials:Assume it existsSuperpolymer composites with a single volume exceeding 1 cubic meter and a texture close to that of rock.(Such as giant polymer concrete components cast in one go), and all other methods of breaking them (blasting, hydraulic shears, giant shredders) have failed.

2. Undifferentiated primary volume reduction of bulk mixed waste:In the assumptionUltra-large-scale municipal solid waste (MSW) sorting and pretreatment lineIn the middle, it is used for unsortedWhole truck of garbageThe initial, roughly crushed process aims to release recyclable materials. However, this has long been superseded by more efficient and environmentally friendly methods.Rotary drum screen, bag crusher/unpacker, coarse crusherThese technologies have been phased out by combined processes.

3. Waste disposal for specific major national defense or scientific research projects:Such as processingLarge composite material equipment components for specific decommissioningThis scenario is highly specialized and confidential, and therefore has no industry reference value.

II. Main Structure and Working Principle (Mining-Grade Heavy Equipment)

1. Core structural components (mining grade):

• Giant segmented cast steel frame structure:Weighing hundreds of tons, the foundation is connected on-site with large bolts and must withstand dynamic loads of thousands of tons. The installation is a large-scale infrastructure project.

• Extra-large jaw plate and guard plate system:A single jaw plate can weigh several tons, usingTop-grade wear-resistant alloyThe replacement requires a heavy-duty crane and is time-consuming.

• Heavy-duty transmission system: Giant alloy steel eccentric shaftSupported byExtra-large double-row roller bearings or Babbitt alloy plain bearingsOn, equippedIndependent high-pressure lubrication station and circulating cooling system。

• Fully automated hydraulic control system:Achieve discharge portWireless remote control adjustment、Intelligent overload protection and resetand key componentsHydraulic locking and disassembly assistance。

• Large inertia flywheel and drive system:Usually byHigh-voltage motors (such as 6kV or 10kV)passHydraulic coupler or soft starterDriven to mitigate the impact of starting current on the power grid.

2. Working principle (rock mechanics principle):
Its design is entirely based on rock.compressive strengthandbrittle fractureCharacteristics. For plasticsToughness, elasticity, low densityCharacteristics, this principleSerious mismatchPlastic is more likely to be absorbed between jaw plates.Compact, stretch or slipRather than an effective fracture.

III. Core Product Features and Fatal Flaws in Plastic Recycling

• Theoretical advantages (in its design field):

  • Unparalleled absolute strength and structural rigidity.

  • The ultimate equipment for handling giant, hard materials.

• The fatal flaw in plastic recycling (a veto point in the decision):

  • The extreme "using a cannon to kill a mosquito" effect:It has extremely high energy consumption (the main motor power is usually above 250kW), with 99% of the energy consumed in the equipment's own inertial motion, friction, and heat generation, rather than in effectively breaking down plastic.The unit energy cost is unbearable。

  • Disastrous output quality:The output will beExtremely heterogeneous mixtureIt contains a lot of dust, huge pieces, and twisted metal (if mixed in).It is completely unable to proceed to any subsequent standard cleaning, sorting, or granulation processes.。

  • Unacceptable system engineering:needSpecially designed concrete foundation, heavy lifting equipment, independent substation, huge installation space, comprehensive dust collection and sound insulation systemThe investment is comparable to that of a small-scale mining and processing plant.

  • Safety and environmental disasters:High noise, high vibration, and high dust levels are extremely unfriendly to operators and the environment.

  • The Nightmare of Maintenance:Replacing a set of jaw plates may require several days of downtime, and the cost of spare parts is staggering.

IV. Technical Parameters (Examples) and Quantification of Inapplicability

• model:PE-1400×1800

• Inlet size: 1400×1800 mm

• Maximum feed particle size: ≤ 1200 mm

• Discharge port adjustment range: 200-400 mm

• Theoretical processing capacity (based on ore): 600-1200 t/h

• Main motor power:250-315 kW or higher

• Equipment weight:100-150 tons or more

Inapplicability Quantitative Analysis:
Assuming it's used for crushing plastics with a density of approximately 0.5 t/m³, the effective cavity filling rate may be less than 30%, and the actual production capacity may only be 10%-15% of the nominal capacity, or approximately 60-180 t/h. However, this requires significant investment:

• Hundreds of kilowatt-hours of electricity consumption per hour.

• This generates tens of tons of mixed crushed material that cannot be used directly and requires secondary or even tertiary processing.

• A large initial investment and operating team.

V. Correct Process Alternatives

If your material is indeed so large that you need to consider a 1400-type jaw crusher.The correct approach is to redesign the entire front-end processing workflow.,For example:

1. Disassembly/cutting at the source:useHydraulic shears, diamond wire saws, high-temperature cuttingMethods such as manual or semi-manual disassembly are used before feeding materials.

2. Specialized heavy-duty shredder:SelectHigh-torque, low-speed dual-shaft or quad-shaft shear shredderIt is specially designed to handle large and tangled items.

3. Multi-stage crushing system:use"Medium-sized jaw crusher or shear crusher + heavy-duty hammer crusher or shredder"The two-stage combination is far more efficient and economical than a single giant jaw crusher.

VI. Conclusions and Strong Recommendations

Conclusion: In waste plastic crushing and washing production lines, the jaw crusher 1400 is a theoretically possible but almost absolutely wrong option in practice.

Strongly recommended:

1. Immediately cease the selection and research for this model.

2. Re-examine and clarify the true physical properties (size, hardness, toughness, composition) of the material to be processed.

3. Consult a professional plastic recycling process engineer or a reputable equipment supplier to redesign the front-end crushing solution.
