Baichy Cone Crusher Plant in Indonesia: Crushing Andesite at 350tph

The Project Background

Indonesia's construction industry has been booming in recent years, leading to a high demand for aggregates. Andesite, a common volcanic rock, has proven to be an excellent source of aggregates due to its strength and durability. A local entrepreneur, with years of experience in the crushing business, recognized the potential of andesite and decided to set up a large - scale crushing plant. However, after using crushers from another supplier for a year, the capacity and performance did not meet expectations. This led to the decision to revamp the plant and increase the capacity to 350 tph while keeping the inherent layout intact. Baichy, a renowned name in the mining machinery industry, was approached to provide a solution.

Characteristics of Andesite and Crushing Challenges

Andesite is a fine - grained igneous rock with a relatively high hardness. It has a density ranging from 2.7 to 3.0 g/cm³ and a mohs hardness of around 6 - 7. These characteristics make it a challenging material to crush. When crushing andesite, the equipment needs to be robust enough to withstand the high impact and abrasion. The previous crushers used by the Indonesian client were unable to handle the andesite efficiently, resulting in low production rates and frequent breakdowns. Additionally, achieving a cubic - shaped final product, which is highly desirable in the market for its better strength and workability in construction, was a struggle with the existing setup.

Baichy's Equipment Solution

1.Primary Crushing

For the primary crushing stage, Baichy recommended a heavy - duty jaw crusher. The jaw crusher is known for its ability to handle large feed sizes and break them into smaller, more manageable pieces. It has a simple structure, high reliability, and a large crushing ratio. The selected jaw crusher can easily take in large chunks of andesite and reduce them to a size suitable for further processing in the secondary crushers.

2.Secondary and Tertiary Crushing

To meet the capacity of 350 tph and achieve the desired cubic - shaped output, Baichy introduced the HPC 220 cone crusher for tertiary crushing and replaced the existing secondary crusher with the CH440 cone crusher. The HPC 220 cone crusher is a high - performance machine that offers high crushing efficiency and excellent product shape. It features a hydraulic adjustment system that allows for easy and accurate setting of the discharge opening, ensuring consistent product size. The CH440 cone crusher, on the other hand, is designed to handle a large volume of material and provide a high reduction ratio. Its advanced crushing chamber design and optimized eccentric throw contribute to better performance when crushing andesite.

3.Screening and Conveying

A crucial part of the plant is the screening and conveying system. Baichy installed high - quality vibrating screens to separate the crushed andesite into different size fractions. The screens are designed to have a high screening efficiency, ensuring that only the desired sizes of aggregates are produced. The conveyors, carefully selected based on the layout and capacity requirements, transport the materials between different stages of the crushing process. Precise measurements were taken to ensure that the location of the motors, oil tanks, and belt conveyors was optimized, especially considering the limited land available at the site.

Advantages of Baichy's Solution

1.Increased Capacity: With the new equipment lineup, the plant has successfully achieved the target capacity of 350 tph. The combination of the S66 and HPC 220 cone crushers, along with the efficient primary jaw crusher, ensures a continuous and high - volume production flow.

2.Improved Product Quality: The cubic - shaped aggregates produced by the Baichy cone crushers are highly sought after in the market. This not only meets the quality requirements of the construction industry but also commands a better price, increasing the profitability of the client's business.

3.Layout Compatibility: Baichy's engineers carefully designed the plant to fit within the existing layout. By accurately measuring and positioning the equipment, they were able to make the most of the limited space available, minimizing the need for major infrastructure changes.

4.Reliability and Durability: Baichy's crushers are built with high - quality materials and advanced manufacturing techniques. This makes them highly reliable and durable, even when operating under the harsh conditions of crushing andesite. The reduced frequency of breakdowns means less down

Baichy Cone Crusher Plant in Indonesia is a testament to the company's ability to provide innovative and effective solutions for crushing challenging materials like andesite. By combining state - of - the - art equipment with careful planning and engineering, Baichy has helped the client achieve a significant increase in production capacity and product quality, meeting the growing demands of the Indonesian construction.
