2PGS Screening type Double Roll Crusher
Shanghai Jianshe Luqiao Machinery Co., Ltd. is a leading stone crushing machine and screening equipments manufacturer in China, provides stone crushing machine and screening equipments for various industries such as mining, building material, metallurgy, environmental protection, transportation, chemistry, energy and so on.
Operational principle: [Double Roll Crusher]
This Double Roll Crusher is to install toothed crown (toothed plate) on two main shafts which will rotate in opposite direction and then build up cutting and stretching force to break material. Main shafts pour out material directly into the whole top space of crusher by driving mechanism (single or double drive) and not restricted by crushing size. After crushing, the material will be discharged between two toothed plate and side wall comb teeth, screening and crushing are finished with shapely product granularity.
Applications: [Double Roll Crusher]
Double Roll Crusher suits for coarse and secondary crushing of various materials such as limestone, granite, iron ore, coal, etc. Its low and short main frame, rather compact and simple structure, make the weight of whole machine is lighter than other crusher by 1/2~1/3 with the same capacity. Therefore, it is preferred product for portable and semi-portable screening and crushing plants. We have three different length boxes of short case, standard case and long case for every serial to meet the needs of different capacities. And various gear teeth for every specification is available to fit different crushing and discharge the materials forcedly without jam, so it rather suits to those sticky and high water content material. This product has the properties of low power consumption and low noise, is environmental and energy conservative product.
