At todays demanding condition maintaining stable operation of rolling mill is becoming difficult. MSD is a hydraulic cylinder installed to mill housing window and press a roll chock against the opposite side with constant force. MSD eliminates gap between roll chocks and mill housing keep rolls in proper position and stabilize rolls.
Operation is similar to the Standard Cone Head however breakage is mostly by attrition rather than impact. Reduction ratio is around 81. Feed size is limited
Bitcoin mining is the process of adding transaction records to Bitcoins public ledger of past transactions or blockchain. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place.
