Why is track mounted crushing plant at the pit rather than fixed plant?

A track-mounted crushing plant is often used at mining or construction sites instead of a fixed plant for several reasons. The decision to use one type of plant over the other depends on various factors, including the specific requirements of the project, the mobility needed, and the overall cost-effectiveness. Here are some reasons why a track-mounted crushing plant might be preferred in certain situations:

1. Mobility and Versatility: Track-mounted crushing plants are highly mobile and can be easily moved from one location to another. This mobility is essential in industries like mining and construction, where the source of raw material or the construction site may change frequently.
2. Cost-Effective: Setting up a fixed crushing plant with a foundation, conveyor systems, and infrastructure can be a significant investment. In contrast, a track-mounted plant can be relocated as needed without the same level of expense, making it a more cost-effective option for temporary or frequently changing sites.
3. Rapid Deployment: Track-mounted plants can be set up quickly, reducing downtime and increasing productivity. This is especially valuable in mining operations where time is of the essence in extracting and processing materials.
4. Environmental Considerations: Some sites have strict environmental regulations, and temporary, mobile crushing plants may be easier to permit and comply with these regulations. Additionally, track-mounted plants can minimize the environmental impact by reducing the need for permanent infrastructure.
5. Maximizing Resource Extraction: In mining operations, ore bodies can be large and extend over a vast area. Using a track-mounted plant allows mining companies to move the crushing operation closer to the active mining area, maximizing the efficiency of resource extraction.
6. Operational Flexibility: Track-mounted crushing plants offer flexibility in terms of crushing and screening processes. Different configurations of equipment can be easily adapted to meet specific project requirements, such as the type of material being processed or the desired end product.
7. Reduced Transportation Costs: When crushing and processing raw materials at or near the extraction point (e.g., at the pit), transportation costs are minimized, as there is less need to haul materials to a fixed processing plant located at a distance.

However, it's important to note that the choice between a track-mounted and fixed plant depends on the specific circumstances of each project. Fixed plants still have their advantages in terms of stability, long-term efficiency, and higher processing capacities. The decision is influenced by factors like the expected project duration, material type, site conditions, and budget constraints.

In summary, a track-mounted crushing plant at the pit is chosen when mobility, cost-effectiveness, and rapid deployment are critical for a specific project or operation.
