What Are the Functions of Mobile Screening and Crushing Plants?
Mobile Crushing and Screening Plants: Efficient All-in-One Solutions
Mobile crushing and screening plants are one-stop plants that are specifically meant for quarrying, mining, and construction work. By making the change from crushing and screening on mobile plants, they are introducing efficiency, flexibility, and economy.
Mobile crushing and screening plants are required in operations where processing of raw material on site is to be ensured in order to save on transport cost and the overall efficiency of operations. Mobile plants have the advantage of portability from place to place, no halt in operation with more less downtime. They are specially useful in outlying areas remote from urban settlements where fixed plants would be time-consuming and costly to establish. Additionally, mobile plants help with the conformity to the environment as they minimize dust, noise, and emissions because of enclosures and high filtration units. Some of the plants are:
-
Feeder
The feeder controls material feed to the crusher to enable continuous processing as well as jamming prevention. By means of belt and apron vibrating plant such as scalper, it ensures maximum efficiency, prevents over/under-loading as well as maximizes equipment life. Design is highly dependent on the product to be fed to the installation.
It is necessary to have a consistent rate of production through a reliable feeder system because an incorrectly set feeder will lead to uneven material flow and crushing bottlenecks. Sophisticated feeder mechanisms, such as variable-speed drives and automated controls, help control the flow rate based on the nature of the material and the capacity of the crusher. Apart from that, modern feeders come equipped with self-cleaning mechanisms to reduce downtime and maintenance requirements, thus making the mobile plant more effective. The choice of feeder also considers the properties of the material such as moisture content, abrasiveness, and particle size distribution in order to enable smooth operation in varying conditions.
2. Grinders
Crushers are the backbone of mobile plants, which reduce stone and mineral to smaller sizes. Crushers differ to encompass jaw, cone, impact, and VSI crushers, which are selected based on the material type and final product. Jaw crushers utilize compressive force, cone crushers utilize a rotating mantle that shears the product, and impact crushers break rocks with a high-speed rotor. Proper selection of crusher decides capacity, efficiency, and end product quality.
The choice of crusher is an important decision that determines the quality of products and the efficiency of a mobile plant.
Jaw crushers are ideal for primary crushing since they can absorb high feed rates and hard rock, while cone crushers are optimally used in secondary and tertiary crushing and offer finer aggregates. Impact crushers, however, are usually used in high-speed operations where particle shaping is important. VSI crushers (Vertical Shaft Impact) are used to achieve a very cubical product, and therefore they are a best fit for concrete and asphalt production. Efficient crushers save energy usage, reduce wear and tear, and enhance the life of key components, which decrease the cost and enhance overall performance.
3. Screening Equipment
Screens classify crushed material by screening with wire mesh or perforated plates. Vibrating screens are normally inclined in mobile plants to offer product quality and to separate material for further treatment. They are simple to install and calibrate to facilitate rapid adjustment as per varying project requirements.
Screening is an important process in material handling and is the step that ensures the final product is of the required size.
High-frequency screens are employed for screening fine particles and heavy-duty screens are employed for heavy, large material.
Mobile plants may be pre-fitted with some multi-deck screening units so various sizes of material can be separated at one time. More recent screening machines are equipped with self-cleaning and anti-clog designs so there is no clogging and maximum efficiency is achieved. The ability to quickly shift between screens of different sizes enhances the flexibility of the plant so that it can easily meet changing project needs. Screening saves material loss and enhances the quality of aggregates used in construction, road construction, and other purposes.
