Abstract

The utility model discloses a break up grader and use shell liner through processing of cold forging fluting, including lining plate body, impact sand grip, construction bolt hole, whole lining plate body use thick matter steel sheet through the cold hammer process shaping as the rectangle structure, the overall structure fastness is good, the lining plate body of rectangle structure transversely has two to assault sand grips through the processing of mechanical grooving formula, assaults the sand grip protrusion and on lining plate body, is equipped with two construction bolt holes on the lining plate body that two are assaulted between the sand grip, the construction bolt hole is designed for the countersunk head type. Impact sand grip through the processing of mechanical grooving formula forms because the grader during operation is being broken up in lining plate body to the protrusion, has strengthened and has thrown the striking effect that the effluvium comes the material to high speed centrifugation to plate lining plate body's abrasion resistance ability has also been changed to a certain extent.

Description

A kind of scattering grader shell liner through cold forging fluting processing

Technical field:

This utility model relates to building material machinery industry technology field, supporting more specifically to a kind of roll squeezer The shell liner processed through cold forging fluting of the scattering grader used.

Background technology:

Crush in cement industry, milling equipment is the key equipment in multiple working procedure, raw material system, raw coal system System, finished product system will relate to the broken of particulate material and grinding, and powder-grinding process is also whole manufacture of cement The operation consumed energy most in technique, therefore, is chasing after of each technical staff to improving the various measures of mill efficiency Ask, in order to reduce the granularity of mill feed material as far as possible, improve mill efficiency, a lot of enterprises often raw mill, Set up one fine crushing operation before finished product mill, and roll squeezer is to apply a more class in finished product powder-grinding process Squash type disintegrating apparatus.Granule materials is extruded by roll squeezer by one group of pressure roller of operating relatively, thus Make material squeeze under high roller pressure broken, some bulks can be bonded to owing under high pressure squeezing broken material Or pie, therefore also need to carry out scattering and grading from roll squeezer material out, by scattering grader at a high speed The peening hammer rotated is centrifuged throwing to material and hits, so that original block material cake is directly smashed or high speed Throwing and be scattered to collide on the liner plate of beater cylinder, therefore the wear liner rate of beater cylinder is higher, uses Although the liner plate plate body of pig iron cast type is with low cost, but using effect is undesirable, and therefore this utility model is sent out Understand a kind of shell liner using thick matter steel plate to process through cold forging fluting, solve liner plate plate body easily quilt The problem of high speed splash grinding abrasion.

Utility model content:

The purpose of this utility model is aiming at the deficiency of prior art, and provides a kind of and use thick matter steel plate warp The scattering grader shell liner that cold forging fluting processes.

Technology solution of the present utility model is as follows:

A kind of scattering grader with through cold forging fluting processing shell liner, including liner plate plate body, impact raised line, Installing bolt hole, the thick matter steel plate of described whole liner plate plate body is shaped to rectangle structure body through Cold Forging, The liner plate plate body of rectangle structure body is laterally machined with two road impact raised lines through mechanical slotting formula, and impact raised line is convex For on liner plate plate body, the liner plate plate body between two road impact raised lines is provided with two and installs bolt hole, installs Bolt hole is the design of countersunk head type.

The beneficial effects of the utility model are: this utility model uses thick matter steel plate to be shaped to through Cold Forging The liner plate plate body of rectangular body, therefore overall structure fastness is good, and the impact processed through mechanical slotting formula is convex Bar, owing to protruding from liner plate plate body, when scattering grader works, enhances and sheds high speed centrifugation throwing The impact effects of material, and change the abrasion resistance properties of plate liner plate plate body the most to a certain extent.

Accompanying drawing illustrates:

Below in conjunction with the accompanying drawings this utility model is described further:

Fig. 1 is the Facad structure schematic diagram of this utility model embodiment；

Fig. 2 is the lateral cross-sectional view of this utility model embodiment.

Detailed description of the invention:

Embodiment: such as Fig. 1, shown in 2, a kind of scattering grader described in the utility model is slotted with through cold forging The shell liner of processing, including liner plate plate body 1, impact raised line 3, installs bolt hole 2, described whole liner plate Plate body 1 is shaped to rectangle structure body with thick matter steel plate through Cold Forging, the liner plate plate body 1 of rectangle structure body The most laterally being machined with two roads impact raised lines 3 through mechanical slotting formula, impact raised line 3 protrudes from liner plate plate body 1, Liner plate plate body 1 between two road impact raised lines 3 is provided with two and installs bolt hole 2, and it is heavy for installing bolt hole 2 Head dummy designs.

Operation principle: when this utility model uses, the present embodiment can be by installing bolt hole 2 by liner plate plate body 1 It is arranged in order on the cylinder barrel being arranged on scattering grader, thus forms the scattering and grading whole circle of machine drum body barrel Protection effect, through the impact raised line 3 that mechanical slotting formula processes, protrudes from liner plate plate body 1, is breaing up During grader work, enhance the impact effects that high speed centrifugation is thrown the material that sheds, and also in certain journey The abrasion resistance properties of plate liner plate plate body is changed on degree.

Claims (2)

1. scattering grader with through cold forging fluting processing a shell liner, including liner plate plate body, impact convex Bar, installation bolt hole, it is characterised in that the thick matter steel plate of described whole liner plate plate body is through Cold Forging molding For rectangle structure body, the liner plate plate body of rectangle structure body is laterally machined with two road impacts through mechanical slotting formula Raised line, the liner plate plate body between two road impact raised lines is provided with two and installs bolt hole, and it is heavy for installing bolt hole Head dummy designs.

A kind of scattering grader the most according to claim 1 shell liner through cold forging fluting processing, It is characterized in that, described impact raised line protrudes from liner plate plate body.
