Roll crushers
Two-roll toothed crushers are effective units for crushing ore and rocks.
Roll crushers are one of the most productive types of crushing equipment for coarse grinding of minerals and rocks. They are distinguished by high productivity, simple design and unpretentiousness in operation.
The principle of operation of crushers is based on crushing the raw material between two rolls with beveled teeth. The teeth of the rollers grab the pieces of material and crush them as they rotate.
Particles are subjected to compression, tension and fracture. Thus, there is a rough crushing of large pieces into smaller fractions.
The equipment is used at mining, mining and processing enterprises for primary grinding of ores and minerals, as well as building materials before further processing. Crushers to obtain the final size of the material fraction suitable for further finer grinding.
Double-roll gear crushersand are produced with smooth and corrugated rolls with a diameter of up to 1600 mm. The mass of crushed pieces can reach 1500 kg. The productivity of crushers varies from 30 to 3500 t/h depending on the size of the equipment and the physical and mechanical properties of the material being processed.
The use of crushers of this type is contraindicated for crushing hard-to-crush, radioactive and explosive materials. The crusher can be used as a stand-alone machine or as part of a plant or production line.Roll crushers are used to grind a wide range of materials: • Ferrous and non-ferrous ores (iron ore, copper ore, nickel ore etc.) • Coal, coke • Building materials (granite, limestone, sandstone, etc.) • Phosphates, apatites and other mineral fertilizers • Shale, clay, kaolin • Expanded clay, slag, concrete, glass • Wood, peat and other organic materials• Grain, oilseeds• Household and industrial waste• Any other hard and brittle materials with a compressive strength of not more than 80-100 MPaRoll crushers have a number of advantages compared to others types of crushing equipment: • Crushers of this type are able to provide very high productivity, up to 1000 m3/h. • Roll crushers have a fairly simple and reliable design without additional devices. This ensures ease of maintenance and repair. Due to the simplicity of the design, maintenance costs and consumables are minimal. • Double roller crushers are capable of crushing very large pieces of material, up to 1500 mm. • The efficiency of double roller crushers can reach 95%, which is higher than other types of equipment. • Crushers can be used for grinding almost any hard and brittle materials. • The service life of roller crushers is at least 10-15 years, subject to the rules of operation. Thus, roller crushers have a number of technological and economic advantages over similar equipment. href="https://tulmash.ru/katalog-oborudovaniya/drobilki-dvuhvalkovyie-zubchatyie/" rel="external noopener">selection of twin-shaft crushers of different power and productivity.
