Basalt Crushing Upgrade Case Study: Romanian Plant Reaches 500 TPH with 2 sets DP440S Single-Cylinder Cone Crushers

Jan 21, 2026

Background: High-Capacity Basalt Crushing Demand in Romania

With the continuous development of infrastructure projects across Eastern Europe, the demand for high-quality basalt aggregates has increased significantly. Basalt, known for its high hardness and abrasiveness, places strict requirements on crushing equipment—especially in high-capacity production lines.

In Cluj-Napoca, Romania, a local aggregate producer operated a basalt crushing plant targeting a stable output of 500 tons per hour. However, limitations in the secondary crushing stage gradually became a bottleneck, restricting overall production efficiency and profitability.

To address this challenge, the plant owner, Mr. Alexandru, began evaluating alternative cone crusher solutions capable of handling hard basalt at high throughput with long-term operational stability.

Crushing Challenge: HP400 Cone Crusher Struggles with Basalt at 500 TPH

Mr. Alexandru has long been engaged in the aggregate production industry in Cluj-Napoca, a key industrial city in northwestern Romania. His crushing plant mainly processes basalt, a hard and abrasive rock that is widely used in highway construction, railway ballast, and concrete aggregate production. As the local infrastructure construction continues to boom, the demand for high-quality basalt aggregates has surged, requiring the plant to achieve a stable output of 500 tons per hour.

Previously, the secondary crushing stage of Mr. Alexandru’s plant was equipped with one HP400 multi-cylinder hydraulic cone crusher. However, after long-term operation, the equipment’s production capacity was barely satisfactory. “The HP400 has certain advantages in fine crushing, but it cannot keep up with our 500t/h production target when processing hard basalt in the secondary crushing stage,” Mr. Alexandru explained during his visit to UNIQUEMAC. “We have tried adjusting the feeding speed and crushing cavity settings, but the output still fails to meet the project requirements, which has become a bottleneck restricting the plant’s development.”

To solve this problem, Mr. Alexandru conducted in-depth research on global cone crusher manufacturers. After comparing product performance, after-sales service, and user reviews from multiple brands, he finally focused on UNIQUEMAC and its star product, the DP440S single-cylinder hydraulic cone crusher. The on-site inspection and test run during his visit further confirmed his confidence in UNIQUEMAC’s equipment.

DP440S Cone Crusher: The Ideal Solution for High-Capacity Basalt Crushing

The reason why Mr. Alexandru chose the DP440S single-cylinder hydraulic cone crusher to replace the original HP400 lies in its unique advantages in hard-rock crushing and high-capacity scenarios. As a professional manufacturer of mining machinery, UNIQUEMAC has optimized the DP440S based on years of experience in aggregate processing, making it perfectly suitable for secondary crushing of hard rocks such as basalt, granite, and diabase.

Compared with multi-cylinder cone crushers like the HP400, the DP440S single-cylinder hydraulic cone crusher has obvious advantages in medium crushing and large throughput. It adopts a high swing frequency, steep cone, and small eccentricity design, which effectively improves the crushing efficiency and material passing capacity. According to actual operation data, the DP440S can increase production capacity by 35%-60% compared with traditional cone crushers when processing hard rocks, which is exactly what Mr. Alexandru’s plant needs. The two DP440S units purchased this time will work together in the secondary crushing stage, ensuring that the entire plant stably reaches the 500-ton-per-hour production target.

In addition to high capacity, the DP440S also has the characteristics of simple structure, low failure rate, and easy maintenance. The single-cylinder hydraulic system simplifies the equipment structure, reduces the number of wearing parts, and lowers the maintenance cost and downtime for users. For mining enterprises, this means higher equipment availability and lower operating costs. Mr. Alexandru also emphasized that the convenient maintenance of the DP440S was one of the important factors for his decision: “In the mining industry, time is money. The simple maintenance of the DP440S can save us a lot of time and labor costs, which is very important for continuous production.”

The DP440S also has excellent overload protection and stable operation performance. Equipped with an advanced hydraulic protection system, the equipment can automatically adjust the discharge port when encountering unbreakable foreign objects (such as iron blocks) to avoid damage to the machine. After the foreign objects are discharged, the discharge port can be automatically reset, ensuring continuous and stable operation of the production line. This is particularly critical for hard-rock crushing scenarios where unexpected situations are likely to occur.

Long-Term Cooperation: Trust Based on Quality and Service

During his visit to UNIQUEMAC, Mr. Alexandru not only inspected the production workshop and product testing process but also had in-depth communication with the technical team and after-sales service team. He highly recognized UNIQUEMAC’s strict quality control system, professional technical support, and perfect after-sales service network. “What impresses me most is UNIQUEMAC’s customer-centric concept. They not only provide high-quality equipment but also tailor-made solutions according to our specific needs,” Mr. Alexandru said. “I am confident that the DP440S cone crushers will bring significant benefits to my plant, and I look forward to establishing a long-term and stable cooperative relationship with UNIQUEMAC.”
