Small jaw crusher is the earlier crushing equipment. Because of its simple structure, reliable work, easy maintenance and overhaul cost, as well as low investment in production and construction, small jaw crusher is still widely used in metallurgy, chemical, building materials, electric power, transportation and other industrial sectors. Luoyang Dahua small jaw crusher production capacity is 7-200 t/h, Max. feed size is 210-770mm, the price is $10,000 – $110,000, which is used for the coarse, medium and fine crushing of various ores and rocks with compressive strength of 147 ~ 245MPa.
✤ Application Range
Small jaw crusher is applied for crushing ores and rocks with compression strength less than 300Mpa. It is mainly used in sand and stone field, mining, coal mining, mechanical sand production, concrete mixing station, dry mortar, power plant desulfurization, building sand, smelting, building materials, highway, railway, water conservancy and chemical industry.
✤ Working Principle
Electrical motor drives the belt wheel to make the swing jaw move following the specific track by eccentric shaft. After the materials enter into the crushing chamber, they are crushed between the two jaw plates by impacting, bending, and striking, and then discharged from the discharge opening.
