Mining crushing plants that move with your operation

Our Primary Crushing Units give you the flexibility you want with the productivity you need.

Combining the high throughput of a common stationary crushing plant with the flexibility of a mobile crushing plant, Semi-Mobile Crushing Plants (SMCPs) are the ideal fit for In-Pit Crushing and Conveying (IPCC) operations and enable you to save money by moving your crusher rather than your materials. Both direct-fed and indirect-fed crushing operations are possible, giving you a complete crushing plant that is customised to your application, whether you’re working with soft, medium or hard rock. 

Our Semi-Mobile Crushing Plants are built on a steel base, rested on pontoon, that there’s no concrete between the crushing plant and the ground required – you can move it at any time using transport crawlers or self-propelled modular transporters (SPMT). This is a heavy-weight crushing station, with the agility of a mobile solution. 


Direct-fed Primary Crushing Units


Offering the highest throughput rates (up to 14,000 tph), our direct-fed Primary Crushing Plants with Gyratory Crushers provide proven, standardised in-pit crushing that can be adapted to any application. Though this is heavy-duty equipment, it has a modular design and comes largely pre-assembled, reducing installation time and cost to a minimum.

Feed material is dumped direct into the feed hopper above the crusher, with one to three tipping points for dump trucks. The Direct-fed Crushing Unit commonly uses one crusher module in combination with a large surge bin. 


Indirect-fed Primary Crushing Units 


Our indirect-fed Primary Crushing Plants are highly suitable for hard rock applications where IPCC systems are in place. Apron feeders are typically used to feed materials to the crusher as the first step in an In-Pit Crushing and Conveying operation. After the crusher, a discharge conveyor connects the Primary Crushing Unit to the following conveyor system. Whether you’re processing overburden, ore or waste rock, we can develop integrated solutions tailored to your application.

In this system, feed material is dumped into the receiving hopper, while the crusher is fed by means of an apron feeder or similar. There can be either one crusher/feeder module or two separate modules. The indirect-fed Crushing Unit does not need a huge surge bin, but instead has a small crusher discharge chute. This mining crushing station can use any primary crusher model, including Gyratory Crusher KB, Eccentric Roll Crusher ERC®, Jaw Crusher EB, RollSizer, Double Roll Crusher etc. 

Reduce emissions with a Semi-Mobile Crushing Station

For most mining operations, the core benefit of a SMCP is that it enables a reduction in transport across the mine site.

Moving materials from one area of the mine to another for crushing is not only time-consuming, it is expensive and polluting – and as mine operators look for ways to cut both costs and CO2 emissions, eliminating these journeys is an obvious first step.


The challenge is – how do you implement a mobile crushing solution without compromising on crushing performance?


With our semi-mobile crushing plants, you don’t have to. High throughputs are still possible, thanks to the sturdy design and advanced technologies.

Minimise material transport costs
Relocate the crusher, not the materials, and save significant sums on transport. 
Achieve high throughput rates
Our Semi-Mobile Crushing Plants can achieve throughputs as high as 14,000 tph because we won’t compromise on performance. 
Reduce emissions from trucking
Transport emissions from trucking account for a significant proportion of a mine’s carbon footprint. Utilising In-Pit Crushing & Conveying systems can cut those transport emissions right down, helping you achieve your environmental targets. 
Adapts to your application
Whatever you’re mining, we can create a Primary Crushing Unit that meets your needs. Our crushing plants can handle soft, medium and hard rock, direct and indirect feeding, and whatever setup works for your application. 

Reduced cost, reduced risk direct- and indirect-fed Primary Crushing Stations

The modularised steel sections of both direct-fed and indirect-fed plants can be widely pre-assembled, which reduces erection time and cost and mitigates risk. Because FLS Primary Crushing Units are widely standardised, costs are reduced.

Direct-fed SMCP key characteristics

  • Compatible with gyratory crushers from 75” to 130” 
  • Capacities up to 14,000 tph 
  • Total plant weight up to 2,500 t 
  • Discharge conveyors up to 3.2 m wide 
  • 1-3 tipping points with steel ramps 
  • Dump trucks up to Ultra Class 360 t 
  • On-board electro-hydraulic jib crane or as variation a bridge crane 
  • Off-board electric, all common standards like IEC, NEMA, etc. applied  
  • Seismic proof construction 

The plant requires no concrete foundations; the plant rests on large pontoons without anchoring on a compacted gravel bed. 


No apron discharge feeder is required. A semi-mobile, extra wide, heavy duty, low speed belt conveyor with VFD drive extracts the crusher product from the surge bin, which reduces the plant height by 3-4 m. 


The off-board installation of the electric equipment and control room including transformers, switchgear, CCTV, etc. are in enclosed compartments on semi-mobile steel substructures to protect the components from dust and vibrations. 

Indirect-fed SMCP key characteristics

  • Compatible with all kinds and sizes of primary crushers 
  • Capacities up to 14,000 tph 
  • Total plant weight up to 2,500 t 
  • Discharge conveyors up to 3.2 m wide 
  • 1-3 tipping points with steel ramps 
  • Dump trucks up to Ultra Class 360 t 
  • On-board electro-hydraulic jib crane or as variation a bridge crane 
  • Off-board electric, all common standards like IEC, NEMA, etc. applied 
  • Seismic proof construction, if required
