What is the working efficiency of the low temperature pulverizer?

Low temperature pulverizer The system takes liquid nitrogen as the cold source, the crushed materials are brittle and easy to be crushed by cooling at low temperature, and then enter the chamber of the mechanical crusher through the high-speed rotation of the impeller The materials and blades, toothed discs, materials and materials are repeatedly impacted, collided, sheared and rubbed with each other to achieve the crushing effect: the crushed materials are classified by the air flow screen classifier And collect Materials that do not meet the fineness requirements will be returned to the bin for further grinding, and most of the air-conditioner will be returned to the bin for recycling The selection and replacement of low-temperature grinding oil, the selection of fuel oil, the wax formation of diesel oil at low temperature, the increase of viscosity, the poor fluidity, the poor atomization, make the combustion process worse, reduce the power and economy of diesel engine In order to make the diesel engine work soft and reduce fuel consumption, the diesel engine with lower freezing point should be selected The general selection principle is: the condensation point of diesel oil is about 5 ℃ lower than the ambient mixing degree During winter maintenance, clean the fuel system of rotary dryer Thoroughly clean all filter screens, replace the fuel filter element, drain the sewage from the oil-water separator and clean it Colleagues check the operation of the oil transfer pump to eliminate the hidden trouble Smashing active cells: at present, we know that cell cryopreservation technology can guarantee the activity of cells Similarly, it is advisable for us to smash drugs with cryopreservation technology The low-temperature pulverizer is to freeze and store the drugs at low temperature first, and freeze the drugs that need to be crushed by liquid nitrogen freezing method, cool the drugs directly to the cell dormancy state, and then crush them by the low-temperature pulverizer, However, it is necessary to avoid the local high-temperature activated cells generated in the grinding process The low-temperature oil with low viscosity should be selected for the replacement of the oil of the low-temperature grinder Try to choose high-performance engine oil This kind of engine oil is not easy to oxidize under high temperature, and will not leave deposits in the precise parts of the diesel engine, which can greatly extend the life of the diesel engine Multi grade engine oil can work in a wide temperature range of slime dryer, and the viscosity grade is generally selected as multi-grade engine oil Replace or clean the oil filter when changing the oil Change the lubricating oil and grease of the low-temperature pulverizer When changing the season for maintenance, change the gear oil in the transmission, transfer case, differential and steering gear into the gear oil used in winter Pay attention to cleaning when changing the oil.
