SY Hydraulic Cone Crusher is an upgraded version of the S series cone crusher . ( A ) insurance, adjustment , locking and hydraulic clean cavity to achieve full control . Small size , such as SY90 (3 ') has cleared the chamber function , SY185 (4-1 / 4' reliability ) clear cavity system has been greatly improved, the large size of such SY280 (5-1 / 2 ' ) and SY400 (7'), clear chamber system is greatly simplified , easy operation and maintenance ; ( 2 ) whether the standard or short head , can packed with feeding, yield 15% higher than the S series is about , between the S -series and H series between the content of fine particles , smaller than the discharge mouth of broken products accounted for by percentage amount is approximately 70 to 75% ; ( 3 ) crushing cavity shape and more room for customers to choose big ; Hydraulic cylinder surface ( 4 ) of the hydraulic system by rolling processing, surface hard , good finish, high dimensional accuracy ; seals imported parts , durable ; ( 5 ) consumable parts , such as rolling acetabular wall , broken walls , the size of the gears, copper sets, bowl-shaped tile , thrust plate so you can swap in S series ; ( 6 ) PLC control system, crusher starts running, stopping the entire process chain to implement automatic control . Such as: the main motor and lubricating oil pressure , oil temperature between the chain of control , lubricating oil temperature of the low temperature heating and high temperature cooling automatic operation , the hydraulic system fluid pressure automatic control. Hydraulic control system can also be implemented manually ; ( 7 ) Dust agency uses dry oil seal. Seal ring with support hose support , compared with spring and spring sleeve structure , reliable , low failure rate , easy assembly and disassembly and repair ; ( 8 ) Built-in locking cylinder , disc when the crusher operation by spring force to adjust the locking sleeve and bearing sets , only when adjusting the port of discharge fluid pressure by compressing the disc spring , loosen the lock to achieve discharge mouth adjustment ; ( 9 ) the use of industrial air-conditioning chillers for cooling lubrication system , crusher applications from high ambient temperature and restricted areas of water shortage .
