1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your aggregate production margins? For plant managers and engineering contractors, the core challenges in primary crushing often center on three critical areas: excessive wear part consumption driving up costperton, unplanned stoppages for maintenance that disrupt entire downstream processes, and inconsistent output gradation that fails to meet stringent project specifications. The financial impact is measurable: every hour of crusher downtime can result in thousands in lost production and labor costs, while premature liner changes add significant material expense. Are you currently evaluating how to achieve higher throughput without a proportional increase in energy consumption? Is reducing the frequency of highrisk, manual interventions in the crushing chamber a priority for your safety goals? The selection of your primary stone crusher machine is not merely an equipment purchase; it is a decisive factor in your site's longterm profitability and operational stability.

2. PRODUCT OVERVIEW

This document details our flagship Jaw Crusher, engineered as a heavyduty primary stone crusher machine for the initial reduction of hard, abrasive materials like granite, basalt, and river rock. Its operational workflow is designed for reliability: (1) Material is fed into the vibrating grizzly feeder, which bypasses fines to optimize chamber loading. (2) Oversize material enters the deep crushing chamber where a highstrength moving jaw compresses it against a fixed jaw. (3) The crushed material discharges at the bottom with a consistent, adjustable output size. (4) The hydraulic toggle system provides automatic overload protection. (5) The process repeats in a continuous cycle with reverse crushing action to minimize clogging.

Application Scope: Ideal for stationary quarry plants, largescale mining operations, and major infrastructure projects requiring primary crushing of materials with compressive strength up to 400 MPa.
Key Limitations: Not suitable for recycling mixed demolition waste with high rebar content without prescreening. For highly abrasive silicarich ores, specific liner metallurgy is recommended.

3. CORE FEATURES

Deep Crushing Chamber & Optimized Kinematics | Technical Basis: Enhanced nip angle and longer stroke profile | Operational Benefit: Increases capacity by up to 15% compared to conventional designs and produces a more uniform product shape | ROI Impact: Higher yield of inspec product reduces recirculation load, directly lowering costperton.

HeavyDuty Fabricated Frame | Technical Basis: Stressrelieved steel plate construction with reinforced ribs | Operational Benefit: Provides exceptional durability against shock loads and fatigue, extending structural life beyond 20 years in severe service | ROI Impact: Eliminates risk of catastrophic frame failure and associated production losses, protecting capital investment.

Hydraulic Toggle Adjustment System | Technical Basis: Replaceable hydraulic cylinder for setting adjustment and tramp iron release | Operational Benefit: Allows operators to adjust CSS quickly under load and automatically reset after an uncrushable event, reducing downtime from hours to minutes | ROI Impact: Minimizes nonproductive time and prevents damage to other components, ensuring higher plant availability.

Premium Bearing Assembly | Technical Basis: Spherical selfaligning roller bearings on both pitman and main frame | Operational Benefit: Supports higher load capacities and compensates for minor misalignments, running cooler than standard bushings | ROI Impact: Extends bearing service life by an average of 30%, reducing spare part inventory costs and associated maintenance labor.

Bolted & Wedged Liner Design | Technical Basis: Modular liner fastening system without traditional backing material | Operational Benefit: Enables faster, safer liner changes; individual segments can be replaced without removing entire jaw sets | ROI Impact: Reduces liner changeout time by approximately 40%, increasing crusher utilization rates.

Integrated Motor Base & Belt Guard | Technical Basis: Unified baseplate design with OSHAcompliant guarding | Operational Benefit: Simplifies installation alignment, enhances drive belt safety, and reduces footprint requirements | ROI Impact: Lowers installation costs by an estimated 15% and ensures compliance from commissioning.

6. APPLICATION SCENARIOS

Granite Quarry Expansion Project

Challenge A quarry operator needed to increase primary circuit throughput by 25% to fulfill a new highway contract but was constrained by space limitations preventing simple plant duplication.
Solution Two highcapacity JC1408 jaw crushers were installed in parallel with existing units but featured deeper chambers for higher volumetric throughput within a similar footprint.
Results Plant throughput increased by 32%. The improved energy efficiency resulted in a net power saving of 11% per ton crushed against projections. The contract was completed 18 days ahead of schedule due to consistent output gradation.

HighAbrasion Iron Ore Processing

Challenge An iron ore mine faced unsustainable wear costs on their primary crusher jaws due to highly abrasive silica content (58% improvement—directly reducing annual liner expenditure by over $120 ,000 USD while improving annual availability by approximately 180 hours.
