How a portable crusher changes your crushing operation?
Portable crusher vs mobile crusher
This article helps you understand what changes when choosing a portable crusher. There is no better or worse type machine but the right tool for your application.
The most noticeable difference between a portable crusher and a mobile crusher is mobility. A portable crusher is mounted on a chassis with wheels and can be moved with a tractor from job to job. In many cases it requires multiple loads to move also additional discharge and transfer conveyors and portable screening plants. Once a portable crushing plant is setup on the job it hardly leaves its spot which requires you to be able to bring material to the crusher. Mobile crushers are track-mounted machines that are self-propelled that can be moved anywhere, anytime without the need of any support equipment. Mobile crushers are moved with a lowboy trailer and can be setup quickly. Larger track mobile crushing plants break down for transport and require more moves. Compact mobile crushers can be moved with a single load.
Even onsite a mobile crusher can track quickly to a new location (e.g. back up closer to the material or move to a different material pile).
Without mobility, you...
The burden associated with moving portable equipment results in higher indirect spending associated with trucking, labor, and setup. These additional costs must be absorbed before profits are generated. Therefore, you need more tonnage to compensate for additional costs. Hence, you will find portable equipment in quarries processing the same material in a high-volume day in and day out, where moving is not necessary.
Without the ability to do also smaller jobs, you ...
Some portable crushers require additional portable screening plants and transfer and discharge conveyors. This takes up more space on the job and makes it difficult to setup on certain jobsites. While this doesn't matter in a wide-open quarry it can be a burden on a tight jobsite. Mobile crushers are more compact because they need to fit on a lowboy trailer. The relatively small footprint makes it easier to place a machine on the jobsite.
Without a compact operation you...
Mobile crushing equipment is designed so that everything fits in between 2 tracks that fit onto a lowboy trailer whereas a portable crusher is a trailer. As a result, you can design a portable crusher with wide openings and more clearances for better accessibility and material flow. The compact nature of a mobile crushing plant puts components much closer to each other which makes it harder to get access to certain components. However, manufacturers have put a lot of effort in finding ways to make access easier. Components lower and fold hydrulically for better access, or they might swing out or open up to improve accessibility.
Portable crushers feature larger feeders, wider conveyors, and large on-board screening plants with 2 or 3 screen decks allowing multiple products to be produced simultaneously. This translates to a large throughput capacity.
Without a large and open design, you...
When operating a portable crushing plant you need to make sure that new feed material is brought continuously to the machine which can result in long loader round-trips. Also walking around the plant for daily maintenance and repairs become longer and you find yourself climbing ladders all the time. Access is generous but high up.
Without short paths, you...
Nathan Henrich with Flatrate Inc runs a concrete pumping and crushing business out of Big Stone, SD. He initially started with a large portable crushing plant. He realized that he was held back crushing concrete because the piles were not stockpiled in convenient places such as a large open pit. Therefore, he switched to the RM 120X Mobile Impactor to gain the freedom to do more jobs and bring the crusher to the material vs. the material to the crusher.
