Wheeled and tracked duo prove just the job for Makapa Corporation in the Philippines

Makapa Corporation (Makapa) is one of the leading construction companies in the Bicol Region of the Philippines. They are a duly registered contractor with the Department of Public Works and Highways (DPWH) and specialize in creating horizontal infrastructures aimed at improving the environment for the local population.

Some of their work has involved construction of flood control structures and drainage systems to protect lives and properties against major flooding in the area. One of their latest projects has been processing river bed gravel to produce sand and gravel for consumption at their construction sites.

It is for this project that the mobile equipment was required; a jaw crusher to reduce the size of the feed material down to a manageable size and a screener to separate into the desired sizes. Not requiring the need to frequently move the equipment around on site after delivery, the wheeled range of Sandvik crushing equipment was proposed and UJ300 jaw crusher chosen due to its size and required capacity.

Low cost operation with Wheeled UJ300

Sandvik UJ300 is a primary crushing unit fully assembled on a single trailer frame and mounted on a double-axle bogie. Electrically driven, it has been designed to offer simple and user-friendly operation aimed at high capacity production at a low cost-per-tonne. Suitable for use in a wide variety of applications, the simple, yet effective design includes many benefits for quick set-up and ease of maintenance, resulting in more uptime and higher productivity.

For Makapa’s Corporation, the UJ300 is ideally suited to their river gravel application. The grizzly feeder system, which has adjustable openings and a by-pass chute for greater flexibility, has a wire cloth screening element beneath which enables efficient removal of natural fines. The material is then fed into the Sandvik jaw crusher, single-toggle type, which possesses a deep, symmetrical crushing chamber for smooth material flow and high reduction efficiency, as well as hydraulic push button controls for simple operation. A soft starting crusher for trouble free operation and frequency inverter for feeder speed control are also fitted to optimize the feed and make the crushing process easier.

Double the processes in one plant

To size the products, Makapa selected the Sandvik QA335 Doublescreen. The QA335 is a highly productive unit that comes equipped with the world-class, heavy-duty Doublescreen system. This innovative technology features two high velocity, angle adjustable screens, where both the primary and secondary screening angles can be adjusted to optimize screening performance and accuracy. With two independent double deck screens, this machine is capable of performing two screening processes in just one plant.

With the type of products Makapa are producing, the Doublescreen system enables them to accurately size the sand and gravel to the required specifications. They are processing G1 ( 20-40 mm) and G2 gravel (40-80 mm) and sand, and are currently producing 30m³, 50m³ and 70m³ respectively, which altogether results in an average capacity of 150m³ per hour. As they are a construction company, they are processing the material for their own consumption and for delivery to their project sites.

Chief Engineer for their equipment and aggregates division, Winston Cipriano, comments “We are pleased with the performance and capacity of the Sandvik mobile plant. We have produced almost 100,000m³ in just 3-4 months with good fuel consumption”. He continues,

We chose Sandvik due to the high quality design and modern technology used on the equipment. We also received good recommendations from our peers in the industry.

Winning combination

This together with the local support from their distributor, Inframachineries Corporation, is a winning combination. Always on hand to support their customers and offer guidance in best operating practices, Winston says “Inframachineries are very accommodating. They often contact us from time to time and we know they are always available should we need them. We would not hesitate in buying Sandvik again in the future.”
