In May 26, 2017, SANDMINE machinery two sets of large scale JCH663 jaw crusher loaded and sent to Burma. This two large scake jaw cruhers, which are purchased by China Railway Group Limited, will be applied to the aggregates production line in Burma, for the stone aggregates primary crushing.

JCH series jaw crusher is a new generation product of SANDMINE, which based on years' expertise in designing and conception and absorbs top crushing technology and research fruit in the world. The maximum capacity of single machine can reach 1200 ton per hour, it is also the larggest equipment we exported.Assembled uses advanced modularization and non-welded frame structure design of high fatigue strength and high reliability. Meanwhile machine assembly design makes transportation and installation more convenient, especially suitable for installation in narrow and small places like undermine and high altitude mining. Symmetrical V formed design, toggle of large obliquity, long stroke, reasonable rotor speed, allow larger materiel block in feeding, higher productivity, homogeneous output granule, less attrition for jaw plate. The whole set of heavy movable jaw plate integrates forged heavy eccentric shaft, high quality bearing of heavy loading, the design of movable jaw plate optimized by finite element analysis. These features assure the stroke resistance and stability. Labyrinth seal and centralized lubricating system prevent the greese of bearing not to be contaminated, and assure the easy lubrication which results in longer function and more stability. The jaw crusher adopts mechanic or hydraulic device to adjust discharge opening. Compared with shim, adjustment by double block is simpler, saver, faster, and reduces downtime. Compared with the traditional jaw crusher, it is not only greatly enhance the stability of the equipment, the customer's return on investment, but also reduce energy consumption, save operating expenses for customers, praised by domestic and foreign customers.

SANDMINE Machinery by the German SK Group Holdings, is the sand aggregate production equipment core technology leader, professional crushing screening equipment suppliers. Since its creation, SANDMINE has always focused on research and innovation of the high performance green crushing and screening equipment of advanced technology, process improvement and lean manufacturing, and adhere to the demand and problem oriented, to implement the strategy of innovation of science and technology, through technology and product innovation to lead the development of the industry, carefully listen to the actual needs of customers, providing high performance sand aggregate production equipment for customers.
