In traditional coal gangue brick manufacturing, the crushing fineness and uniformity of raw materials directly determine the compressive strength and yield of the final bricks. However, many older brick plants have long struggled with aging equipment, excessive over-crushing, and high energy consumption during the raw material processing stage. These issues not only increase production costs but also restrict product quality. Recently, a domestic brick plant took decisive action to upgrade its production line by completely removing its legacy 600×900 jaw crusher and feeder. In their place, they introduced the 1210 Fully Hydraulic Double Roller Sand Maker manufactured by Huashengming Heavy Industry, successfully unlocking the bottleneck in the refined processing of coal gangue.
Background: Legacy Equipment Hits a Bottleneck, Urgent Need for Brick-Making Process Upgrade
The plant’s original crushing system gradually exposed shortcomings such as unstable particle size control and uneven output when processing a mixture of coal gangue and shale. Due to the poor connection between the primary and secondary crushing stages, the materials entering the aging silo were inconsistent in size. This not only affected the stable operation of the subsequent extruder but also made it difficult for the final fired bricks to meet high standards in terms of density and appearance. To completely reverse this situation, the plant manager, after extensive research and comparison, selected the 1210 Fully Hydraulic Double Roller Sand Maker from Huashengming Heavy Industry as the core secondary crushing equipment.
On-Site Performance: The 1210 Fully Hydraulic Double Roller Machine Breaks Through with Precision
At the renovation site, the Huashengming 1210 double roller sand maker demonstrated exceptional adaptability to the working conditions. The equipment is primarily responsible for precisely crushing coal gangue and shale mixtures (with feed sizes up to 8 cm) down to under 8 mm. With the intelligent adjustment function of the fully hydraulic system, operators can make one-click micro-adjustments to the gap between the two rollers based on the characteristics of different batches of raw materials, ensuring that the output particle size always remains within the ideal range.
Compared to traditional impact crushers, the Huashengming double roller machine uses a pure physical extrusion principle. This not only significantly reduces the over-crushing rate but also produces coal gangue particles with a uniform cubic shape. After entering the aging silo, this high-quality fine material undergoes 2 to 3 days of sufficient aging, resulting in a more uniform moisture distribution and significantly enhanced plasticity, laying a perfect foundation for the subsequent automatic extrusion, cutting, and stacking processes.
Coal Gangue
Highlighted Benefits: Cost Reduction, Efficiency Gains, and Comprehensive Quality Leap
This equipment upgrade not only solved the pain points of raw material processing but also brought tangible economic benefits to the brick plant. On the one hand, the fully hydraulic double roller machine operates smoothly with low energy consumption. Its core roller skins are made of super wear-resistant materials, which significantly reduces the replacement frequency and maintenance costs of wearing parts. On the other hand, thanks to the precise control of crushing fineness, the plant’s qualified rate of finished bricks has significantly increased, while the scrap rate has dropped substantially.
The successful renovation of this brick plant clearly demonstrates that in the face of increasingly fierce market competition and strict environmental requirements, brick and tile enterprises must “take real action” in core processes by introducing efficient and intelligent crushing equipment to truly achieve cost reduction and efficiency gains. Relying on its mature double roller crushing technology and extensive on-site renovation experience, Huashengming Heavy Industry is helping an increasing number of traditional brick plants break through development bottlenecks and move forward more steadily on the path of coal gangue resource utilization.
