Double roll crusher is composed of two separate drive roller, squeeze rolling mill shear force and rotation relative to the broken material, also called roll crusher. Double roll crusher, Shanghai crusher, crushing high hardness less ore, jaw crusher, rock and refractory materials. Double roll crusher in the refractory broken machinery more than excellent effect. Refractoriness is not lower than 1580 ℃ for a class of inorganic non-metallic materials. Refractory materials are widely used in industry metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., the largest amount in the metallurgical industry, accounting for 50% to 60% of total output. The physical properties of refractory materials include structural properties, thermal properties, mechanical properties, performance and job performance. Refractory structural properties include porosity, bulk density, water absorption, air permeability, pore size distribution. Refractory thermal properties include thermal conductivity, thermal expansion coefficient, specific heat, thermal capacity, thermal conductive coefficient, thermal emission rate. Mechanical properties of refractories include compressive strength, tensile strength, flexural strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength, elastic modulus. Performance refractories include refractoriness, load softening temperature, reheating linear change, thermal shock resistance, slag resistance, acid resistance, alkali resistance, water resistance, anti-CO erosion resistance, electrical conductivity, oxidation resistance Wait. Double roll crusher is very wearable, grinding rolls on its optional wear plates, wear plates using advanced wear-resistant materials, continuous service life of up to a year or more, severe wear, remove the cover that is can be replaced. After more than a hundred years of process improvement, modern jaw crusher and crusher of a century ago, and in a completely different composition not only crusher machine chamber into a moving jaw and static jaw, but also a full range of imitation the animal's jaws motion for crushing materials. Often used in large-scale ore crushing and materials, and energy-saving design jaw in the original one, a high efficiency crushing equipment also joined the important factor of environmental protection, and therefore have been widely used in construction, roads, railways, mining, and other industrial fields. Next we will see him in more important areas. It is precisely because it has manufactured crusher broken material easily, relatively simple structure, easy maintenance, and many other advantages, so even after a good many years, but is still not out of the market, can still be used as ore, materials, marble and other hard and on the roll crusher, or a softer texture ore and other materials. His versatility can be said it is still relatively high. For now, our crusher industry a good momentum of development, he walked all the way by virtue of the introduction of foreign advanced technology, combined with China now the stone situation, a lengthy independent research and development, roll crusher, now developed a variety of models and versatile multi-purpose jaw crusher, crusher industry in China jaw crusher regarded the development of more mature, and in the country's major industries, especially the construction industry has occupied an important Location.
