Uniform discharging device

Technical Field

The utility model relates to a grinding divides the material equipment technical field, especially relates to an even glassware down.

Background

Roller presses are crushing plants that have been developed internationally in the mid-eighties of the last century. The new extrusion grinding process has obvious energy saving effect and is a new technology for developing new grinding process due to the common attention of cement industry.

The roller press adopts the principle of high-pressure material layer crushing and adopts the working mode of single-particle grouping to achieve the effects of saving energy and increasing yield. The particle size of the brittle material is greatly reduced by high-pressure extrusion, the content of fine powder smaller than 0.08mm reaches 20-40%, the content of fine powder smaller than 2mm reaches 60-70%, and a large number of cracks exist in all the extruded materials, so that the required energy consumption is greatly reduced when the materials are ground in the next working procedure.

The semi-finished products produced by the roller press are fed into the V-shaped powder concentrator for scattering and sorting, so that the roller press can run stably, the system yield is improved, and the material granularity is divided into 2 or 3 types according to different processes. When the grinding process is a combined grinding system, the materials are sorted into 2 types: the fine powder is ground by ball milling, and the coarse particles are returned to the roller press to be extruded and ground again; when the grinding process is a semi-final grinding system, the materials are sorted into 3 types: the fine powder is put into a finished product, the medium coarse powder is subjected to ball milling and grinding, the coarse particles are returned to the roller press for secondary grinding, and a semi-final grinding system is used for sorting the finished product generated by the roller press instead of grinding in a ball mill, so that the over-grinding phenomenon of the ball mill can be effectively reduced, the energy consumption is saved, and the yield is improved.

The working process of the V-shaped powder concentrator is as follows: the material is fed from the upper feed inlet to form a material curtain, and the airflow entering the powder concentrator enters from the air inlet and passes through the material curtain to be contacted with the material. In the powder selecting area, materials are collided and dispersed for many times between the stepped scattering plates at the inlet side of the powder selecting machine, so that the effects of scattering material blocks, fully exposing fine powder and prolonging the retention time of a material curtain in the powder selecting area are achieved. The coarse material falls along the scattering plate and is discharged, and the material-carrying gas is discharged from an air outlet through a guide fan.

In a general grinding process, a nonstandard pipeline is usually adopted to convey extruded materials of a roller press lifted by a circulating bucket and feed the extruded materials into a V-shaped powder concentrator. In order to improve the dispersion effect of the materials, a one-to-three technology is adopted for a non-standard pipeline of a new production line, namely, one feeding pipeline is adopted, the pipeline is divided into three pipelines when the V selection is fast fed in, and the materials are fed into the V selection in three parts. The feeding uniformity by utilizing the 'one-to-three' technology is obviously improved compared with the uniformity of one feeding pipe, but the structure is not fundamentally changed, the material after being divided still has the condition of partial material deviation, the conditions of partial non-uniform V material selecting screen and short circuit by air are caused, the sorting airflow can not fully pass through the thick material screen, the qualified material is taken away in time, more fine powder enters the roller press again, the work of the roller press is influenced, the working current is low, and meanwhile, one strand of fine powder passes through the roller press, so that the current fluctuation of the roller press is large. Because the qualified materials can not be sorted in time, the machine-hour yield of the system is low.
