Condition: new, functionality: fully functional, power: 30 kW (40.79 HP), Year of construction: 2025, A double roller crusher for sand making, also known as a roller sand making machine, is a processing machine that utilizes two rollers to crush and reshape coarse-grained materials such as rock, stone, and ore into finer particles. This type of equipment is commonly used in the production of construction aggregates, artificial sand, and other materials used in various industries. Here are key features and aspects of a double roller crusher for sand making: 1. Double Roller Design: - The crusher has two parallel, counter-rotating rollers that exert pressure on the material. The gap between the rollers can be adjusted to control the size of the crushed particles. 2. Crushing Mechanism: - The material is fed between the two rollers, and as they rotate, the material is drawn into the crushing zone. The rollers compress and crush the material, reducing it to the desired size. 3. Material Feed and Discharge: - The material is typically fed into the top of the crusher and is crushed between the rollers. The crushed material exits at the bottom of the machine. 4. Adjustable Gap Settings: - The gap between the rollers is adjustable, allowing for control over the final size of the crushed material. This feature is essential for producing materials of different particle sizes. 5. Roller Surface Design: - The surface of the rollers may be smooth or have corrugations to enhance the gripping and crushing action. The choice of roller surface design depends on the characteristics of the material being processed. 6. High Efficiency: - Double roller crushers are known for their high efficiency in crushing and shaping materials. The dual roller design provides a more consistent and controlled process compared to single roller crushers. 7. Versatility: - These crushers are versatile and can be used for various materials, including hard and soft rocks, ores, and other aggregates. They are particularly suitable for producing artificial sand. Cgsdpfxjq Ngamj Ahvjw 8. Dust and Noise Control: - Some double roller crushers are equipped with features to control dust emissions and reduce noise during operation, improving the working environment. 9. Application in Sand Making: - Double roller crushers for sand making are commonly used to produce fine aggregates and artificial sand. They are employed in the production of high-quality sand for construction and other applications. 10. Maintenance and Safety: - Regular maintenance is essential for optimal performance. Safety features, such as emergency stops and safety guards, are often incorporated to ensure safe operation. 11. Motor and Drive System: - A powerful motor and a reliable drive system are essential components to drive the rotation of the rollers and ensure consistent and efficient crushing. The specific design and features of double roller crushers for sand making can vary among different models and manufacturers. When selecting or using this type of equipment, it's important to refer to the manufacturer's guidelines and specifications for proper operation and maintenance.
