Description

Screening machine bypass online crushing and crushing device

Technical field:

The utility model relates to a screening device in the grinding technology, in particular to an on-line crushing and pulverizing device in a bypass of a screening machine.

Background technique:

Due to the requirements of the process, grinding, crushing, and calcination equipment often require materials that meet the specified particle size to be "eaten". Therefore, the materials must be screened for primary selection, and then screened and finely selected. However, for the screened materials, the fine materials are qualified materials, but the coarse materials with larger particle sizes are often troublesome to deal with.

In the traditional production line, after screening, the "qualified" particle size materials enter the next process. Unqualified materials are often discharged out of the frame through the bypass. After stacking to a certain material layer, it will be transported away by loader and dump truck for recycling and crushing again.

It is obvious that the traditional process is still blank for on-line bypass crushing, because screening and crushing are often treated as separate parts in traditional process design, and are not considered as a whole. As a result, the screening unit completes the screening function, and the coarse material after screening often does not have a suitable treatment process.

The coarse material released through the bypass cannot be rationally utilized, which instead causes the process line to be extended. In addition, the stockpiled coarse materials virtually reduce the utilization rate of the limited area of plant land. If the investment is too small, it is necessary to increase the number of mechanical manpower cycles, and if the site is large, a larger yard is required. Additional machinery (loaders, trucks) and manpower need to be invested, which increases additional costs and the on-site operating environment is harsh.

Utility model content:

The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art, to provide a screening machine bypass online crushing device with reasonable design, shortened process flow, reduced site occupation and improved work efficiency.

The technical scheme of the utility model is:

An on-line crushing and crushing device with a bypass of a screening machine, comprising a crusher, the feed port of the crusher communicates with the lower end of the bypass coarse material pipe, and the upper end of the bypass coarse material pipe communicates with the coarse material outlet of the screening machine , the discharge port of the crusher is connected to the upper end of the coarse material chute, the lower end of the coarse material chute corresponds to the conveyor belt conveyor, and the fine material outlet of the sieving machine communicates with the upper end of the fine material chute , the lower end of the fine material chute corresponds to the conveying belt conveyor.

The lower end of the bypass coarse material pipe is connected to the upper end of the tapered transition pipe section, the lower end of the tapered transition pipe section communicates with the feed inlet of the crusher, the coarse material chute is conical, and its upper end diameter is greater than the lower diameter.

The crusher includes a frame, the frame is provided with a motor and a rotating shaft, the two are connected through a transmission mechanism, and a breaking hammer is arranged at intervals on the rotating shaft, and the rotating shaft and the breaking hammer are set in the casing. The casing is fixed on the frame, and the casing is provided with the feeding port and the discharging port.

The breaking hammer adopts the structure of a hammer head and a hammer shaft, and the hammer shaft is fixed on the rotating shaft, and the lengths of the hammer shafts are different.

The beneficial effects of the utility model are:

1. The utility model effectively utilizes the original equipment (feeding belt, supply frame and other equipment) and the site, reduces the investment amount of the equipment and the quantity of the equipment, improves the process efficiency, shortens the supply route of the material, and is beneficial to the crushing process. Obvious economic effects and broad prospects.

2. The utility model realizes on-line crushing on the bypass, which changes the situation that after the separation of traditional bulk materials, it is difficult to cooperate with the production line for coarse materials that do not meet the requirements of the screening, and the circulation is more complicated. Through the rational use of the bypass, the Coarse material is directly crushed into a process modification that meets the particle size requirements.

3. The utility model makes reasonable use of space and technology, so that the routine process of bypassing and emptying unqualified materials is changed to an internal circulation process. The site occupied by coarse materials and secondary handling are canceled, making the process arrangement more compact and reasonable, saving energy and expenses. The screening and crushing processes are closely combined to meet the particle size requirements of the process and reduce environmental pollution and energy waste.

4. The crushed qualified materials of the utility model enter the vertical mill through the conveying belt conveyor, and are further pulverized to form a continuous process, which has high efficiency, saves labor and time.

5. The utility model has the advantages of reasonable design, shortened technological process, reduced site occupation and improved work efficiency. It has a wide range of applications, is easy to popularize and implement, and has obvious economic benefits.
