Optimizing Capacity in Portable Crushing Operations

Portable crushing plant provides a versatile mobile crushing solution for quarries, resource industries, recycling, and construction waste applications.

Portable crushing plants, also known as portable crushers, provide a versatile mobile crushing solution for quarries, resource industries, recycling, and construction waste applications. These mobile crushing machines utilize the same crushing equipment as stationary crushers but on a more compact design mounted on trailers or skids for high mobility.

Some key characteristics of portable crushing plant includes their ability to be rapidly deployed to a work site and moved from one location to another. This makes them well-suited for operations with short-term extractive phases or maintenance work on infrastructure projects. Modern portable crushers feature advanced automation, remote control capabilities, and improved fuel efficiencies over older mobile crushing equipment.

The typical components included in a portable crushing plant are a feed hopper, vibrating grizzly feeder, primary jaw crusher, engine or electric power pack, and conveyor belts for product stockpiling or transport. More advanced configurations may incorporate additional screens or secondary cone crushers to produce specified sized end products efficiently.

Portable crushing plants are versatile crushing machines that can be moved easily from one location to another. They consist of a robust crusher mounted on a mobile wheeled or tracked platform, along with associated equipment like feeders, conveyors and screens.

Small portable jaw crushers up to 150 tons per hour

Mid-sized plants from 150-300 tons per hour

Large plants exceeding 300 tons per hour, some at over 400 tons per hour

Some key advantages of portable crusher plant include their ability to be transported easily even to remote job sites, without the need for permanent foundations. This makes them well-suited for short-term construction and mining operations. Modern portable crushing plants are automated with features like remote control and monitoring capabilities.

Typical components of a portable crushing plant operation include a feeding hopper where material is fed into the plant. A vibrating grizzly feeder then controls the feed material size entering the primary crusher. Jaw crushers and cone crushers are commonly used primary crushing units in portable plants. Crushed product is transported from the crusher via conveyor belts for further processing or stockpiling.

More advanced portable crushing plants feature additional screens to separate material into specified size fractions. Some plants also incorporate a secondary cone crusher to produce finely sized end products efficiently. The whole crushing process is powered by on-board diesel engines or electric motors for full mobility.

The capacity and configuration of the crushing unit depends on the application and desired production levels. Here are some more details about portable crushing plant capacities:

Capacity can range widely depending on the specific model and configuration. Most portable crushers are designed to process 50-400 tons per hour.

Primary factors that influence capacity include the jaw or cone crusher size, presence of additional screens/conveyors, and material properties.

Larger jaw openings or cone crusher cavities allow higher throughput of material. Multiple crushers/screens also increase capacity.

Harder, more abrasive rock materials will achieve a lower capacity than soft, friable rocks with the same plant. Moisture content also impacts capacity.

Proper crusher settings to achieve the required product size in the fewest passes increases possible throughput.

Feed particle size and gradation delivered to the plant affects its capacity utilization. Pre-screening and scalping improves this.

Operational uptime with minimal downtime is crucial to achieve the nominal full capacity.

Manufacturers can provide estimated capacities based on typical material properties. But field tests are needed for measuring actual performance.

Portable plant capacity needs to match the daily production targets of the mining/construction application. Oversized plants are inefficient.

So in summary, portable crusher plants between 50-400 TPH are common, but actual achievable capacity depends on several job-specific factors. Proper sizing and setup is important.
