Product introduction

Roll sand making machine, pebbles and sand making machine is suitable for compression strength less than 250Mpa, the solid material less than 35% moisture in the crushing and fine crushing operations, such as broken iron ore, quartz, potassium (sodium) feldspar, limestone, HeLuanShi, silicon metal, barite, Xuan Wuyan, granite, steel slag, cement clinker, construction garbage (concrete), shale, coal, coke, lime, clay, bentonite, chemical raw materials etc.. Can be widely used in mining, thermal power, cement, ceramics, metallurgy, chemical industry, building materials and other industries, with the use of low maintenance costs, low water requirements, reliable performance, low power consumption, less dust, low noise characteristics.

The roller pebble sand making machine, sand making machine equipped with two roller crusher, according to the size demanded by the user, the roll surface is divided into flat surface of roller and roller surface surfacing in two forms, flat roller surface model is applicable to the feed grain size is less than 80mm, 1- 10mm finished product size crushing operation. Welding roller surface model is applicable to the feed grain size is less than 150mm, 5-, 30mm in the finished size requirements of fine works.

If the material the compressive strength more than 250Mpa are recommended to choose such roller (grinding) machine, according to user requirements is divided into triangle belt and coupling transmission (hard link) in two ways, the device has no power in the mine situation can be changed into diesel or gasoline engine as power.

Working principle

The roller pebble sand making machine, sand making machine is a crushing roller with two high-strength wear-resistant alloy, high extrusion pressure to the relative rotation of the crushing material, the material into the two roll gap (type V, two by crushing cavity) crushing roller relative extrusion and shear force in rotation, rolling, shearing and meshing grinding, the material is crushed into the required size is discharged from the discharge opening.
