River rock compositions varies by deposit, often containing a wide range of sizes from fine particles to large cobbles, along with silt or organic matter. Screening is essential to turn this raw material into clean, marketable products.

Scalping screens remove oversize rocks and heavy debris early in the process to protect downstream equipment. Finishing screens then separate the material into precise size fractions such as pea gravel, drain rock, or concrete aggregate, ensuring consistent gradation and quality for construction and landscaping applications.

River rock is composed primarily of quartz, granite, basalt, and other dense minerals that have been naturally rounded and smoothed by water over time. While the rounded shape makes them easier to handle, river rock is one of the toughest rock types to crush.

This abrasiveness makes crushing river rock more demanding on equipment compared to softer aggregates. Crusher selection depends on desired product size, wear tolerance, and throughput requirements, with special attention paid to liner materials and wear part maintenance due to the hardness of the feed.

Once river rock is screened or crushed to the desired size, conveyors move the material between stages with minimal handling, reducing the need for loaders and decreasing fuel use and labor.

Their ability to create large, well-organized stockpiles helps prevent material segregation and contamination, especially important when producing multiple size grades like pea gravel or drain rock. Mobile tracked units with adjustable discharge heights allow flexible placement and radial movement, making them ideal for dynamic operations where pile shape and position must adapt to changing volumes or site conditions.

Granite is a hard, abrasive igneous rock ideal for high-strength aggregate but challenging to crush. It requires heavy-duty equipment built for durability.

Jaw crushers handle primary reduction, while cone crushers provide consistent secondary and tertiary crushing. Due to granite’s toughness, wear parts must be high quality and well-maintained to ensure efficient, continuous operation and minimal downtime.

Screening granite typically involves two key stages: scalping and finishing. Scalping screens are placed before the crusher to remove fines and soil, which helps reduce wear on the crushing equipment and promotes more consistent flow.

After the material is crushed, double or triple deck finishing screens separate the rock into defined size fractions for use in construction or road base. Due to granite’s hardness and angularity, this process presents challenges such as accelerated wear on screen media and the risk of blinding, especially when handling finer materials under heavy throughput.

Whether you are moving granite, feeding into another machine, or stock piling. We have tracked conveyor and conveyor systems ready to move the material in an efficient and profitable way.

Choose from custom conveyor systems or tracked units for maximum adaptability on site.

Coal is a friable, stratified sedimentary rock with variable moisture and clay content, making screening both essential and occasionally challenging.

Frontline carries both scalping and finishing screeners from Keestrack and Sandvik. Scalping screeners are used to remove fines and separate any oversized material, increasing efficiency of downstream crushing. Finishing or incline screeners on the other hand use adjustable angles and multiple decks to accurately separate coal into specific sizes.

Coal’s fine particles and moisture can cause dust, carryback on belts, or buildup at transfer points. When feeding crushers or screeners, a steady flow is important to avoid surges or clogs, and feeder conveyors help keep things consistent.

For stockpiling, tracked stackers are a great option since they can build large piles without using loaders, which helps reduce compaction and keeps the material clean. Good belt design and dust control go a long way in keeping coal moving smoothly.
