8. A grinding method of an intelligent vertical grinding device is characterized by comprising the following steps:
the start the motor drives the mill is rotatory, follows simultaneously behind the dog-house sends into the material, and the material falls the top cap of mushroom umbrella cover form earlier the mill drives material on the top cap is to peripheral dispersion under the centrifugal force effect, and the dispersed material rolls under the effect of grinding roller and mill, then sieves out the material via sieve mesh one, sieve mesh two and sieve mesh three, and the in-process of rolling still through opening pneumatic ball valve, let compressed gas to the radial slot of mill lets in, can let compressed air be pulse form and exhaust in proper order, strikes the material in the radial slot, makes the bed of material boil to in time overturn out and via the sieve mesh one, sieve mesh two or sieve mesh three send out with the granule that reaches the product requirement in the material.
9. The grinding method of the intelligent vertical grinding device according to claim 8, further comprising:
the controller controls other pneumatic ball valves to be closed and only opens the controller corresponding to the air supply of the groove airflow inlet so as to automatically concentrate airflow to strengthen impact and conduct the corresponding radial groove, and in addition, the pressure of each groove airflow inlet can be displayed on the liquid crystal screen;
can carry out two and three intelligent control of sieve mesh, this intelligent control includes: the controller is connected with the second hydraulic jack and the first hydraulic jack in advance in a control mode, the controller controls the piston rod of the second hydraulic jack to stretch and retract so as to automatically control the size of the combined sieve mesh, and the size of the combined sieve mesh at that time can be displayed on the liquid crystal display; the controller controls the piston rod of the first hydraulic jack to stretch and retract so as to automatically control the displacement of the static jaw plate, so that the distance between the static jaw plate and the movable jaw plate can be adjusted in real time, and in addition, the distance between the static jaw plate and the movable jaw plate can be displayed on a liquid crystal screen;
can carry out the intelligent control of total intake valve, this intelligent control includes: be equipped with the air inlet valve on the supply-air outlet in advance and be equipped with the admission valve on the air intake all be provided with pressure sensor and speedtransmitter in supply-air outlet and the air inlet, pressure sensor, speedtransmitter, air inlet valve and admission valve all with controller control connection, according to the product specification requirement of needs, the opening degree of controller automatic adjustment air inlet valve, control air inlet velocity of flow, LCD screen real-time display is by the wind pressure and the wind speed of each air intake that its pressure sensor and the speedtransmitter that correspond convey.
