1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your project margins? In aggregate production, mining, and C&D recycling, inefficient crushing and screening is a primary bottleneck. Common challenges include:
Excessive Downtime: Unplanned stops for liner changes, blockages, and mechanical issues halt your entire production line.
High Operating Costs: Rising energy consumption, premature wear part replacement, and high recirculating loads directly impact your cost per ton.
Inconsistent Product Quality: Offspec material leads to product rejection, wasted loads, and dissatisfied customers.
Rigid Plant Configuration: Fixed systems struggle to adapt to changing feed material or required product specifications, limiting operational flexibility.
Safety & Maintenance Complexity: Hazardous manual interventions and lengthy service procedures increase risk and labor costs.

Is your current crushing and screening equipment configured to maximize throughput while minimizing cost per ton? The solution lies in selecting machinery engineered to address these specific operational and financial pressures.

2. PRODUCT OVERVIEW

Modern mobile crushing and screening equipment represents a significant evolution from traditional fixedplant setups. These integrated systems typically combine a primary crusher (e.g., jaw or impactor), a secondary/tertiary crusher (e.g., cone or impactor), and a multideck vibrating screen onto tracked or wheeled chassis.

The operational workflow is streamlined:
1. Primary Reduction: Feed material is sized by the initial crusher.
2. PreScreening & Recirculation: A screen deck separates correctly sized product from material requiring further processing, efficiently managing crusher load.
3. Secondary/Tertiary Crushing: Oversize material is routed to a subsequent crusher for final reduction.
4. Final Product Sorting: Multiple screen decks sort crushed material into precise, saleable fractions (e.g., base course, chips, sand).
5. Stockpiling: Conveyors stack finished products.

This equipment is optimal for quarrying, contract crushing, recycling (concrete, asphalt), and mining applications requiring mobility between sites or within a large pit. Its primary limitation is the maximum feed size capacity compared to the largest stationary primary crushers.

3. CORE FEATURES

Direct Drive Crushers | Technical Basis: Elimination of Vbelts & tensioners via direct coupling of hydraulic motor to crusher | Operational Benefit: Reduced maintenance time by up to 50%, higher power transmission efficiency | ROI Impact: Lower labor costs for drive maintenance and up to 10% improved fuel efficiency per ton crushed.

Advanced Prescreen & Bypass System | Technical Basis: Independent grizzly feeder with reject conveyor before the crusher | Operational Benefit: Removes fines and natural contaminants prior to crushing, reducing wear and increasing capacity | ROI Impact: Extends wear part life by 1530% and reduces uncrushable materialrelated damage.

PLCBased Intelligent Control System | Technical Basis: Centralized automation with realtime monitoring of critical parameters (pressure, temperature, power draw) | Operational Benefit: Allows operators to optimize settings remotely; provides diagnostic alerts to prevent failures | ROI Impact: Minimizes unscheduled downtime; enables less experienced operators to achieve peak efficiency.

Hydraulic Setting Adjustment (HSA) | Technical Basis: Hydraulic cylinders adjust crusher closedside setting (CSS) in seconds versus manual shims | Operational Benefit: Enables quick product size changes without stopping the machine; enhances safety by keeping personnel clear of the chamber | ROI Impact: Increases plant flexibility for different contracts; reduces nonproductive time during changeovers.

HeavyDuty Feeder & Hopper Design | Technical Basis: Reinforced hopper with optimal geometry; stepped grizzly bars on feeder | Operational Benefit: Minimizes bridging and blockages; ensures consistent feed rate to the crusher cavity | ROI Impact: Maintains steady throughput targets; eliminates costly downtime from manual clearing operations.

6. APPLICATION SCENARIOS

Granite Quarry Production Expansion

Challenge: A quarry needed higher throughput without expanding its fixed plant footprint or increasing truck haul distances from the face.
Solution: Deployment of a trackmounted primary jaw crushing and screening plant at the blast face, feeding directly into the existing fixed secondary circuit via long conveyors.
Results: Reduced truck cycle time by eliminating haul from face to primary crusher, increasing overall site throughput by 22% while lowering fuel and tire costs associated with haul trucks.

Construction & Demolition Waste Recycling

Challenge: A recycling yard faced high contamination in final aggregate products and frequent jamming from unremoved rebar/wire in concrete feed.
Solution: Implementation of a mobile impact crushing and screening plant equipped with an aggressive prescreen grizzly and an overhead crossbelt magnet system.
