200-250tph Basalt Crushing Plant
This client already had a crushing plant and wanted to expand its capacity. We recommended a PE900X1200 jaw crusher, an HST250 coarse chamber cone crusher, and an HP300 cone crusher. The entire crushing line features an integral steel structure, facilitating on-site assembly and disassembly. Installation of the entire production line took 45 days, with full support from our MR engineers throughout the process. Final production was 240 to 260 TPH, exceeding the client’s expectations.

Concerns and Solutions
Concern 1:
You recommended using a combination of single-cylinder and multi-cylinder hydraulic cone crushers. Why didn’t you recommend two of the same cone crushers?
MR Solution 1:
We recommend two different cone crushers to ensure high throughput and a uniform cubic shape in the final product.
Due to the large size of the raw materials, if an HP300 crusher is used as a secondary crusher, some large pieces might have difficulty entering the cone crusher chamber or could become clogged due to the prolonged crushing time. Therefore, we suggest using a single-cylinder cone crusher with a coarse chamber as the secondary crushing stage. This is because it can not only crush larger materials but also ensures high throughput. The single-cylinder hydraulic cone crusher has a more inclined crushing chamber and faster material discharge, ensuring smooth stone entry into the tertiary crusher. A multi-cylinder hydraulic cone crusher can achieve layered crushing, ensuring the shape of the particles in the final product.
Question 1:
Is it necessary to frequently adjust the discharge port size of a multi-cylinder hydraulic cone crusher? How is it adjusted?
MR Solution 1:
A multi-cylinder hydraulic cone crusher requires adjusting the discharge port size in two situations:
1. When you want to modify the output size.
2. When the concave wears down and the discharge size increases, it is necessary to adjust it to reduce it and maintain the same output size. Adjusting the discharge port is very convenient and is easily done via the control panel’s touchscreen.

Equipment Delivery
When shipping the equipment for this project, there are a large number of machines, especially key equipment such as the jaw crusher, the multi-cylinder hydraulic cone crusher, and the single-cylinder hydraulic cone crusher.
Taking the jaw crusher as an example, before shipment, MR personnel again check the condition of the equipment, inspecting both the structure and the manufacturing of the components, as well as the condition of the external paint, to ensure that everything is in perfect working order. In addition, important components are packed to protect them from moisture and rust. Finally, MR personnel verify the quantity of goods, making sure that no wooden crates containing accessories are left behind.
After-sales service
We have a professional engineering team in South America that guarantees a 24-hour response. For all equipment supplied by MR, our engineers will travel to the customer’s facilities to provide comprehensive technical support throughout the entire process. This service includes: installation and commissioning supervision, staff training, and real-time monitoring and reporting to headquarters to ensure installation progress and quickly identify and resolve any technical issues.
Customer Comments
The client had previously used Metso equipment production lines, so their requirements for the machinery were very high, which posed a real challenge for MR. MR engineers traveled to the site and personally guided the client’s team throughout the entire assembly process, ensuring a smooth installation of the entire basalt crushing line. After more than a month of installation work, the production line quickly entered the production testing phase and subsequently began full operation. The end result was an output of 240-260 tons per hour, exceeding the client’s expectations. Furthermore, all the equipment performed flawlessly, leaving the client completely satisfied.
