The technical problem to be solved in the present invention is realized by following scheme: the present invention includes frame, frame is installed main frame and motor, main shaft is passed described main body and is connected with two end faces up and down of body by bearing, charging aperture is established in body upper end, discharging opening is established in lower end, cutterhead installed by main shaft, uniform pore openings in cutterhead card, be used for the vertical rod of grafting cutter, plug-in mounting cutting blade (quantity is according to the degree of grinding increase and decrease that will reach) in cutter vertical rod, steel pipe socket interval is used between blade and between blade and cutterhead, ensure that fly cutter can not collide when running up, circular hole is all opened in described blade two ends, exchange to facilitate two and use, in body, impeller is installed in lower end, impeller is connected with main shaft, impeller together operates with main shaft when machine operation, by the material that crushes by impeller fan-out, solve material stock problem in casing, simultaneously, rotation because of impeller makes to form negative pressure in machine chamber, the material entering feed hopper is sucked, the speed of vane rotary and the size of blade, quantity determines speed and the amount of charging and discharging, main frame inwall installs replaceable dentation steel-casting, after material enters pulverizer, enter from top to bottom to be broken up after between fly cutter with steel-casting and tear into fritter, finally be ground into Powdered, pulverizer is taken out of through impeller.Because material enters pulverizer from above, go out from down, and described pulverizer does not install screen cloth, solve the problem that pulverizer pulverizes wet feed charging, putty and discharging difficulty.Meanwhile, the body of pulverizer is opened the detection window that about 1/6th justifies size, and detection window external welding one detecting gate, opens an aperture in the upper surface cutter vertical rod lengthwise position of pulverizer, facilitates cutter vertical rod from upper extraction more allowing blade replacement.It is from upper feeding that this structure has broken conventional size reduction machine, from the left or right discharging, and as from left discharging, understand material stock on the right side of in machine chamber, right side sieve screen apertures can even block in bridging, and vice versa; Because of in machine chamber, there is putty, material stock problem in screen cloth, input and output material is also smooth, so conventional size reduction machine output does not just increase.

The present invention is a kind of vertical structure pulverizer, main shaft and fly cutter rotate in vertical direction, namely rotate around Y-axis, break the problem of conventional size reduction machine around the easy putty of X-axis rotary work, described pulverizer material upper entering and lower leaving, crushing process is incremental from top to bottom, complete equipment continuous productive process, one integrated mass.

Impeller of the present invention is arranged in machine chamber, is connected with main shaft, has simultaneously and solves pulverizer discharging and feed problems.

Screen cloth is not installed in machine chamber of the present invention, degree of crushing be by the quantity of fly cutter and air quantity size also namely input and output material number control.The present invention is because of without screen cloth, and the rotation of impeller controls input and output material, so not putty, also just directly can pulverize wet stock; In machine chamber not material stock, there is not screen cloth putty, there is no the not bridging of screen cloth sieve screen apertures, not stifled sieve screen apertures one is said, input and output material is smooth and easy, pulverizer does not flog a dead horse, thus output is high, low in energy consumption, high efficiency, energy-conservation.

Described access panel is the window of one about 1/6th circle size that body is opened, and has installed door, and close this door, whole machine chamber is still integrated, and access door is convenient for changing blade and repair apparatus.

Advantage of the present invention is: described pulverizer has structurally done significant improvement, innovation, the convenience changed the performance of machine, output, power consumption, continuous operation, maintenance maintenance, spare and accessory parts, has had important breakthrough to the fastidious property of raw material, crushing effect aspect.Operation process is putty, not material stock not, and employment is few, equipment fault is low, production cost is low, high financial profit, is beneficial to popularization, is applicable to integrated mill's equalization.
