Green Sand Cooling System in Brazil
In its ongoing commitment to innovation and foundry process improvement, JML Industrie has installed its latest green sand cooling system at a leading foundry in Brazil. Equipped with a moisture management and control system, the TVR model will significantly enhance our client’s production quality and demonstrates JML Industrie’s technical expertise and commitment to providing cutting-edge solutions. Innovation at the Heart of the Process The TVR model green sand cooler represents the pinnacle of JML Industrie’s technology. Designed to integrate after an existing MU type premixer, this advanced system utilizes a precise mechanism to dose and mix water with sand before entering the fluidized bed cooler. The key to its operation lies in the optimal transfer of calories needed for water evaporation, a critical process to achieve the desired sand quality. The air flow, essential for evaporation, is meticulously managed through a longitudinal chamber beneath the fluidized bed, divided into several compartments equipped with adjustable butterfly valves. This ensures even air distribution and effective evaporation, while maintaining sand integrity through micro-perforated stainless steel sheet panels, thus ensuring increased longevity and system performance. A Highly Advanced Management System At the heart of the TVR cooler lies a sophisticated management system, designed to automatically adjust air and water volumes based on the specific characteristics of the sand, such as weight, temperature, and moisture. This ability to dynamically adapt ensures a consistent output sand quality, meeting the strictest standards required by our client. Exceptional Results The technical data speaks volumes. With a processing capacity of 120 tons per hour and an ambient temperature of 34°C, the system significantly reduces sand temperature from an input of 80-120°C to an output of 34-38°C, while achieving an optimal moisture level of 2.00% ± 0.15. These results attest to JML Industrie’s capability to tackle technical challenges and provide solutions that not only meet but exceed client expectations.

From Flame to Forge : A Journey Through the History of Foundry
The origins of foundry date back to prehistoric times when our ancestors discovered the potential of fire to shape metals. The earliest foundries were rudimentary: pits dug in the ground, fueled by charcoal, where metals were melted and molded. This technique then refined over millennia, with the introduction of clay furnaces and the use of stone, and then metal molds. 🪙The Bronze and Iron Age The Bronze Age (around 3000 BC) marks a key step, with the alloy of copper and tin to produce bronze, a more resistant and versatile material. Later, the Iron Age introduced an even stronger material, paving the way for new applications and technologies. 💥The Industrial Revolution: A Major Turning Point The 18th century Industrial Revolution was a catalyst for the foundry industry. The invention of the steam engine and the development of mass production techniques allowed the production of metal parts in large quantities and with increased precision. Foundries transformed into industrial facilities, with high-performance furnaces and sophisticated molding techniques. 🌐Today: The Era of Technology and Environment Today, foundries are at the forefront of technology.

Maximizing your foundry’s productivity: installing a runner breaker.
The foundry industry is based on complex processes where every step counts. Our clients, aware of the importance of innovation in improving productivity, quality and profitability, are always on the lookout for innovative solutions. With this in mind, we recently worked with one of our long-standing client to improve its production process with the installation of a high-performance runner breaker. Our solution: a tailor-made runner breaker for optimum results. One of the most common challenges in foundry operations is the management of casting jets, which often require size adjustment. After a careful analysis of our client’s needs and installation, our team of experts designed a custom runner breaker to precisely meet the foundry’s requirements, taking into account the size of the parts to be ground, the required throughput and the quality of the final production. A simple process for impeccable results. The operation of our runner breaker is simple and efficient: castings are transported by a conveyor belt from a vibrating screen to the runner breaker. Inside, the runner breaker performs a precise, controlled size reduction. The advantages of our foundry runner breaker: Benefit#1: Precise, efficient size reduction Our runner breaker offers precise size reduction, a crucial element in ensuring that castings are ready for the next phase of the process, without wasting material. This improvement has a positive impact on the quality of finished products, while generating significant savings in time and costs. Benefit #2: Optimum residue management Below the crusher, a second vibrating screen collects the crushed jets, separating fine sand from other materials thanks to a perforated grid. This function acts like a screen, ensuring that only the necessary elements progress to the skips, reducing waste while optimizing material utilization. Benefit #3: Quick and easy skip changeover Another innovative aspect of our solution is the ease with which the skips can be changed. Mounted on a turntable, skips can be changed quickly and efficiently using a cart, eliminating any loss of time. Benefit #4: Increased profitability At our client’s site, the installation of our foundry runner breaker has led to tangible improvements. Production has become smoother, waste has been reduced and the quality of finished products has risen. These results have had a positive impact on the company’s profitability, strengthening its market position. The installation of a runner breaker at our client’s site is an example of our commitment to working with them to overcome industrial challenges. At JML, we are determined to continue innovating and providing tailor-made solutions to meet the needs of the ever-changing foundry industry.

Client project : Suction and moisture control of sand
Final phase – Delivery and acceptance of equipment A few months ago, we told you about our latest achievement: the installation of a cooling drum for one of our customers in eastern France. This installation incorporates two specific technology, with the use of a burner within the suction network, the use of a burner within the suction network, aiming to control the suction process and the implementation of our sand moisture management system in the cooling barrel, an essential element of the process molding. Why is sand moisture a major issue in foundry operations? The sand used for molding contain 3% of moisture. When this sand is drawn into the pipes of the suction system, particularly at the level of shake-out, dust loaded with clay associated with humid air can cause blockages and clogging. This reduces suction process efficiency, increases production downtime, and generates unnecessary maintenance costs. Eliminate the moisture with a suction burner To fix this issue, we integrate a burner into the suction network of our client’s sandshop. The main goal is to dry out the air in the suction lines, preventing moisture from disrupting the system’s operations. The burner operates by evaporating excess moisture from the intake air, allowing the dust to circulate more efficiently. Our solution: an automated moisture management system inside the drum We have also set up a device designed by our teams within the cooling drum to manage sand moisture. This system relies on an optimal temperature measurement at the drum inlet, depending on the volume of water initially used. At the outlet of the de-bottlenecking drum, moisture and temperature values are continuously monitored as the sand is transported on the conveyor belt. If necessary, additional water is added in real time to maintain the programmed moisture level. The whole process is fully automated by our teams, which means it requires little maintenance, apart from a periodic check of the moisture sensor to ensure it is properly calibrated. Quality and Economy: Optimize the molding process Implementing a moisture management system as well as the installation of a burner in the dust suctions has many advantages for our client. It optimizes the efficiency of the suction process by reducing obstructions in the pipes, which translates into a significant reduction in production costs. In addition, automatic adjustment of sand moisture ensures consistent molding quality, improving the overall quality of products. If you have any questions or require further information about our moisture management equipment, please do not hesitate to contact us.
