300-400 tons of river gravel production line during investment

When investing in a river gravel production line with a capacity of 300-400 tons per hour, it is important to consider several factors, including the type of equipment required, the layout of the production line, and the estimated investment cost. Here is a general overview of the production line and the investment required:

1. Crushing equipment: You will need a primary crushing machine to process the river gravel. A jaw crusher or an impact crusher would be suitable for this purpose. The crushing capacity of these machines ranges from 100-600 tons per hour, depending on the model and specifications. The cost of a jaw crusher can range from $?100,000 to $?300,000, while an impact crusher can cost between $?150,000 and $?500,000.

2. Screening equipment: You will also need a screening machine to separate the crushed gravel into different size fractions. A vibrating screen or a trommel screen can be used for this purpose. The cost of a vibrating screen can range from $?50,000 to $?150,000, while a trommel screen can cost between $?100,000 and $?300,000.

3. Conveyor belts: Conveyor belts will be required to transport the river gravel between the crushing and screening machines. The cost of conveyor belts can vary depending on the length, width, and material, but they generally cost between $?10,000 and $?50,000.

4. Control system: A control system is essential for monitoring and adjusting the operation of the production line. This can include a control panel, sensors, and software. The cost of a basic control system can range from $?10,000 to $?30,000, while a more advanced system can cost up to $?100,000.

5. Other costs: Additional costs to consider include the foundation and infrastructure for the production line, electrical and mechanical installation, and transportation and installation of the equipment. These costs can vary depending on the location and conditions of the site.

Based on these factors, the estimated investment cost for a river gravel production line with a capacity of 300-400 tons per hour can range from $?400,000 to $?1.5 million, not including the land, infrastructure, and labor costs. It is essential to consult with experienced professionals and equipment suppliers to get a more accurate estimate for your specific project.
