Abstract
The utility model pertains to a lining board used in mills, in particular to a mill reverse guiding material lining board. A cog body (3) of a certain height is arranged on the arc surface of an arc shaped plate (1); the front segment of the cog body (3) is vertical to the axle of the mill; the back segment of the cog body (3) and the axle of the mill form an angle of 45+-5 degrees. The cog body (3) combines with the arc shaped plate (1) into an integral part which is cast at a single time with metal wear resistant materials. The utility model is characterized in that during the operation of the mill, a grinding body and the materials to be ground makes the materials to produce a reverse component force and a forward resistant force under the comprehensive effect of self gravity, the guidance of the cog body (3), and the circular material dam so that circulating grinding is formed by part of the materials; consequently, the grinding route of the materials is prolonged, the grinding time is increased, and the grinding ability is enhanced. Thereby the content of micro powder in the product is increased, the amount of sieve residue is reduced, specific surface area is increased, and the particle grading is optimized, thus improving the early stage strength of cement, and providing technical guarantee for the quality, high yield, and energy save of the product.
Description
Technical field
The utility model belongs to the grinding technology field.In particular for short grinding machine improve mill efficiency realize high-quality, high yield, energy-conservation, adapt to cement quality and integrate with, and a kind of multi-functional reverse guide liner plate that designs with international standard.
Background technology
At present; what China's cement industry adopted grinds body, steel ball classification, accelerates material flow, strengthens the steel ball stirring action with protection; adding big steel ball hoisting depth etc. has for the lining board of grinder of purpose: wave mode liner plate, press strip liner plate, ladder lining board, classifying lining board, trench liner, angle, garden square liner plate etc.; these liner plates all do not have the effect that changes material direction of advance in the grinding machine, more do not have the function of reverse guide.Production practices show: closed circuit short mill and open circuit grinder system, and poor for grindability, advance the big material in abrasive particle footpath, short because of milling time and stroke, and make high-quality, high yield, energy-conservation being restricted of grinding engineering.
Summary of the invention
The design of the reverse guide liner plate of the utility model, purpose is: prolong material and grind stroke and increase milling time in mill, it is big because of advancing the grind materials particle diameter to solve closed circuit short mill and open circuit grinder system, grindability is poor, and the cement mill production capacity that causes descends, technical problems such as powder content is low in the product, and the specific area value is little, and early strength is low.
Technical solutions of the utility model are: be cast with bolt hole (2) and having the fin body (3) that is provided with certain altitude on the cambered surface of certain thickness arc (1).The leading portion of fin body (3) and grinding machine axis normal, back segment and grinding machine axis be at 45 ± 5 ° of angles, and fin body (3) and arc (1) connection adopt the metal wear resistant material one-step casting to form for whole.
The reverse guide liner plate of the utility model grinding machine is compared with the technical performance of the various arc liner plates that present grinding machine uses, have following property: the abrasive body in the mill running with by grinding material at self gravitation with tiltedly under the guide effect of fin body, produce reverse component, partial material is driven in the wrong direction, prolong the grinding stroke of material.The annular material blocking ring that straight fin body constitutes, the milling time of increase material.Two fin body comprehensive functions formed " grinding again " process, the grinding machine grainding capacity is increased substantially, produce the effect of " short mill lengthization ", thereby the powder content in the product is increased, screen over-size reduces, the specific area value increases, and grain composition is tending towards optimizing, and cement early strength improves, big for solving material particular diameter, the grindability difference improves grinding efficiency, realizes high-quality, high yield, the energy-conservation and enforcement ISO international standard of cement grinding, and the reliable technique assurance is provided.
Description of drawings Fig. 1 is a structural representation of the present utility model.Fig. 2 is that the A-A of the utility model Fig. 1 is to cut-away view.Fig. 3 is a perspective view of the present utility model.
The specific embodiment
According to Fig. 1, Fig. 2, shown in Figure 3, be cast with bolt hole (2) and having the fin body (3) that is provided with certain altitude on the cambered surface of certain thickness arc (1).The leading portion of fin body (3) and grinding machine axis normal, back segment and grinding machine axis be at 45 ± 5 ° of angles.Fin body (3) is integral body with arc (1) connection, adopts the metal wear resistant material one-step casting to form.Replace original liner plate that grinding machine grinds the storehouse end with this novel lining plate during application, replace length for grinding the 10-20% of storehouse axial length.
Claims (2)
- It is 1, a kind of that certain thickness grinding machine arc liner plate is innovated and development forms the reverse guide liner plate of grinding machine by having, it is characterized in that: the fin body (3) that on the cambered surface of arc (1), is provided with certain altitude, the leading portion of fin body (3) and grinding machine axis normal, back segment and grinding machine axis be at 45 ± 5 ° of angles, fin body (3) is integral body with arc (1) connection, constitutes the reverse guide liner plate of grinding machine.
- 2, according to the reverse guide liner plate of claims 1 described grinding machine, it is characterized in that: the leading portion of fin body (3) and grinding machine axis normal, back segment and grinding machine axis be at 45 ± 5 ° of angles.
