The utility model is intended to address the above problem, and a kind of vertical grinding machine is provided, and it is easy to use, has avoided existing equipment just can reach the problem of granularity requirements by iterative cycles, and efficiency is high, and discharging-material size is even, less energy consumption, and its technical scheme adopting is as follows:
A vertical grinding machine, is characterized in that, comprising:
Frame,
Motor, it is installed in frame;
Main driving wheel, it is connected with the rotating shaft of motor;
Driven pulley, it is driven by main driving wheel by transmission mechanism;
Main casing, itself and frame Joint, it has charging aperture and discharging opening;
Hollow spindle, it is connected with driven pulley by shaft coupling and is dynamically connected by bearing rotary with main casing, has mass transport cavity in described hollow spindle;
For the abrading cylinder of splendid attire material and mill ball, it surrounds the grinding chamber of sealing, and described grinding chamber is connected with charging aperture;
Abrasive disk, it is arranged on grinding chamber and its and has large groove;
Grading wheel, it is arranged in abrasive disk and only on it, has the little groove that can pass through for small particles material, described grading wheel and abrasive disk all with hollow spindle Joint;
Described conveying cavity top is connected with discharging opening, and bottom is connected with grinding chamber.
Optionally, described transmission mechanism is belt.
On technique scheme basis, also comprise the cooling water jecket for cooling abrading cylinder, it has cooling water outlet and inlet, and described cooling water jecket surrounds abrading cylinder.
On technique scheme basis, on described hollow spindle, there is the shaft seal that prevents material from leakage in grinding chamber.
On technique scheme basis, described main casing has can hold the discharge chamber that grinds rear material, and described discharge chamber is between the passage of carrying cavity top and discharging opening to be connected.
On technique scheme basis, in the circumferential exterior surface of described abrasive disk, be formed with the stirring projection that several are separated from each other.
The utlity model has following advantage: easy to use, avoided existing equipment just can reach the problem of granularity requirements by iterative cycles, efficiency is high, discharging-material size is even; By vertical ring-hammer grinding machine, carry out dry method coarse crushing and be less than after 100 orders to granularity, then mix slurry by agitator, be then pumped in this vertical grinding machine, discharging-material size can reach 2000 orders, than existing technique, can economize on electricity 50%, reduce energy consumption, efficiency improves 50%.
