Limestone is a non-metallic mineral resource, widely used in building materials, chemical industry, metallurgy and many other fields. Double roller crusher, also known as roll sand making machine, is suitable for crushing medium hardness and brittle materials, especially for limestone, such as medium hardness of brittle minerals, double roll sand making machine can show its unique advantages.
Double roller crusher is suitable for medium and fine crushing of solid materials with compressive strength less than 250mpa and moisture less than 35%, such as crushing iron ore, quartzite, potassium (sodium) feldspar, limestone, river pebbles, silicon metal, barite, basalt, granite, steel slag, cement clinker, construction waste (concrete), shale, quicklime, coal, coke, clay, bentonite, chemical raw materials and so on. Widely used in mining, thermoelectricity, cement ceramics, metallurgy, chemical industry, building materials industry crushing operations. With low maintenance costs. Low water requirements, reliable performance, low power consumption, low dust, low noise and other characteristics.
The double roll crusher is equipped with two crushing rolls. According to the granularity required by the user. The roll surface is divided into two forms: flat roll surface and welded roll surface. The flat roll surface model is suitable for fine crushing with the feed granularity less than 80mm and the finished product granularity of 1-10mm. Surfacing roller models are suitable for feeding size less than 150mm, the finished product size of 5-30mm fine crushing operations.
Double roller crusher Working Principle
Double-roll crusher is to use two high-strength wear-resistant alloy crushing rolls. Relative rotation of the high squeeze to crush the material. The material into the gap between the two rolls (v-type crushing chamber), by the relative rotation of the two crushing rolls of the squeeze and shear force. In the squeezing, shear and grinding, the material will be crushed into the required size from the discharge port discharge.
roller crusehr Working Principle
Huashengming heavy work as a large domestic sand crushing equipment manufacturers, with very mature crushing production technology and rich production experience. Its roller sand making machine, complete models, wide range of production capacity, according to the size of the model. The hourly capacity can range from dozens of tonnes to hundreds of tonnes. To meet the needs of different scales of limestone processing production line. In terms of sand output rate, its optimised crushing chamber and reasonable roll surface structure design can directly produce beautiful sand with high sand output rate, which can effectively help users to improve product quality and market competitiveness, coupled with its compact structural design, small footprint, suitable for a variety of site layouts, it is the ideal equipment to achieve efficient transformation of limestone resources.
