Roller sand making machine sand making effect, core advantages: particle size control, finished product quality, production efficiency and adaptability. Roller sand making machine has become the preferred equipment for the production of mechanism sand by virtue of its precise particle size control, high efficiency and energy saving, and strong adaptability and other advantages. In actual application, it is necessary to adjust the parameters with the material characteristics and pay attention to maintenance to maximise its performance.
Roller sand making machine sand making effect
Roller sand making machine Uniformity and adjustability of particle size
Precise adjustment mechanism
Adjust the gap between the two rollers of the roller sand making machine (wedge device or increase or decrease shims) to control the particle size of the material, the range is usually between 1-20mm, to meet the different requirements of the material. For example, when processing river pebbles, the finished sand grains have high roundness and low needle flake content, which is in line with the construction standard.
Regular grain shape sand making effect
The shape of the finished sand particles is mostly cubic or almost spherical. With internal cracks formed due to high-pressure extrusion. Low energy consumption for subsequent grinding and conducive to improving the strength of concrete.
High-efficiency production and energy-saving features
High crushing efficiency
Roller sand making machine crushes materials with high pressure (up to 50-200MPa). The production efficiency is 30%-40% higher than that of hammer crusher, and the energy consumption is 20%-30% lower.
Low maintenance cost
Roller sand making machine roller surface with high wear-resistant materials, service life of more than one year. Low maintenance frequency, and simple structure, easy maintenance.
Material adaptability and environmental performance
Wide applicability: It can process medium and high hardness materials (such as granite, river pebbles, limestone, etc.). And it is suitable for both dry and wet materials. However, it should be noted that high humidity materials may cause sticky rollers, which need to be pre-treated. Environmental protection design
Equipped with dustproof board, closed conveyor and spray dust reduction system, the dust and noise control is better than traditional equipment. n line with environmental protection requirements.
Quality stability guarantee
Intelligent control of parameters: Through real-time monitoring of roll gap, speed and other parameters, combined with automated system adjustment, to ensure uniform particle size distribution. For example, by adjusting the gap, the stability of grading of sand and gravel in a certain production line has been significantly improved. Equipment Durability
High-strength bearings and wear-resistant roller body design, together with regular lubrication and maintenance, prolongs equipment life and reduces downtime.
Limitations and countermeasures
Wear and energy consumption: wear and tear of the roll surface may affect the grain shape after long-term use, and regular maintenance and replacement is required; high energy consumption when processing high hardness materials, and it is recommended to optimise the raw material pre-treatment process. Large material processing: front iron removal device is needed to prevent metal impurities from damaging the equipment, and to avoid accidental ejection of large ores.
