How efficient is the low temperature mill?

The low-temperature mill system uses liquid nitrogen as a cold source. After the pulverized material is cooled and frigorized at a low temperature, it enters the mechanical pulverizer cavity and rotates through the impeller at high speed. Materials and blades, toothed discs, materials and materials Under the combined effects of repeated impact, collision, shearing, and friction, the pulverization effect is achieved: the pulverized material is classified by an airflow sieve classifier and collected. The material that has not reached the fineness requirement returns to the silo and continues to be crushed, and most of the cold air is returned to the silo for recycling.

Selection and replacement of low-temperature mill oil, fuel oil selection, diesel wax is easy to wax at low temperature, viscosity increases, fluidity is poor, atomization is bad, the combustion process is deteriorated, and the power and economy of the diesel engine are reduced. In order to soften the diesel engine and reduce fuel consumption, diesel with a lower freezing point should be used. The general selection principle is: the condensation point of diesel is about 5 °C lower than the environmental mixing. The drum dryer fuel system should be cleaned during winter maintenance. Thoroughly clean all the filters, replace the fuel filter, discharge the sewage from the oil-water separator and clean it. Colleagues check the operation of the oil pump to eliminate the hidden troubles. Smashing active cells: At present, we know that cell cryopreservation technology can ensure the activity of cells. It is also desirable to use chilling technology to pulverize drugs. The low-temperature mill firstly freezes the drug, and freezes the drug we need to pulverize by liquid nitrogen freezing method. The drug is directly cooled to the dormant state of the cell, and then pulverized by a low-temperature pulverizer, but it is necessary to avoid smashing. The local high temperature generated during the process wakes up the active cells.

For the replacement of low-temperature mill oil, low-temperature oil with low viscosity should be used. Try to use high-performance engine oil. This kind of oil is not easy to oxidize at high temperature, and it will not leave any deposits in the precision 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 dryers. Generally, the viscosity grade is multi-grade oil. Replace or clean the oil filter while changing the oil. The low-temperature mill replaces the lubricating oil and grease. When changing the season, the gear oil in the transmission, the transfer case, the differential, and the steering gear is replaced with the gear oil for winter. Pay attention to the cleaning when changing the oil.
