In May 2025, a Bulgarian customer signed an order to purchase mineral sizer processed ore. After more than six months of intensive production, the critical moment of delivery finally arrived. After a day of packing and boxing, all the equipment has been properly placed and loaded onto the vehicle, ready for transportation.

The client's current project involves crushing ore with a processing capacity of 2,000 tons per hour. The maximum feed size is 1300mm, and the required output size is no more than 300mm. With a large processing capacity and continuous crushing, coupled with the high hardness of the ore, the performance and stability requirements for the equipment are relatively high. When we were formulating the plan with the client, we fully considered these factors. To control the particle size of the crushed materials, a secondary crushing device, the crushing beam, is added.

The area between the teeth of the two crushing rollers is the primary crushing zone. Through the interlocking of the crushing roller teeth, primary crushing is achieved, mainly responsible for crushing large pieces of materials. The two triangular areas between the crushing roller and the crushing beam are the secondary crushing zones. Through the meshing of the teeth of the crushing roller and the crushing beam, the secondary crushing of the material is achieved. Through the two crushing processes, the crushing ratio is greatly improved, and the output particle size is uniform, which can well meet the customer's requirement that the output size is less than or equal to 300mm.

The hardness of the ore has a significant impact on the wear of the mineral sizer roller teeth. High wear-resistant materials are selected to manufacture the roller teeth. This material has excellent hardness and toughness, which can maintain a long service life in high-intensity crushing operations, effectively reducing the maintenance cost and downtime of the equipment. In response to the working requirements of large processing capacity and continuous crushing, the drive system of the equipment needs to keep up with the working pace. It adopts a combination of high-power and highly reliable motors and reducers to ensure that the mineral sizer has sufficient power and stable operation during long-term operation.

The intelligent control system's electrical control box can monitor the operating status of the equipment in real time, such as the rotational speed, current, and temperature of the crushing roller. Once an abnormal situation occurs, the system will immediately issue an alarm and automatically take corresponding protective measures, further ensuring the safety and stability of the mineral sizer.

During the production process of mineral sizer, customers visit in person. One reason is to come to the factory to inspect the goods, and the other is to come to check the shipping situation when the goods are about to be dispatched. They carefully inspected the appearance, structure and assembly quality of each component of the mineral sizer, and highly praised our production process and quality control system. During the inspection process, the customer also paid special attention to the ease of operation and maintenance of the equipment. We arranged technicians on site to demonstrate and explain. The customer gained a clear understanding of the operation process and maintenance points of the equipment and was full of confidence in the subsequent use and maintenance.
