Squeeze crusher selection calculation First, determine the actual required throughput of the extruder, the calculation formula is summarized as follows: the operating rate of the knife extrusion pulverizer is generally less than the daily return volume of the extruder The percentage of the calculation is generally as follows: the kiln's table time output, the raw material consumption quota, and the raw material consumption of the kiln in the kiln. The hourly throughput of the extruder material required in the knife type meets the hourly consumption of limestone in the kiln calcination. It can be seen from the calculation that the passing ability of the extrusion pulverizer must be above to meet the minimum production requirements. According to the current extrusion machine applied to the raw material extrusion, the passing ability is one under the optimal operating condition. For the medium-grinding limestone, the high-grade extrusion machine should be selected. The extruder with this specification can be used to better realize its power saving advantages. Problems to be paid attention to in the process layout When the extruder is used for pre-grinding or squeezing limestone, an intermediate buffer tank must be provided to separate the extrusion from the grinding to solve the difficulty of production and control due to the imbalance of production capacity. Since the material size of the extruder is required to have a certain degree of non-uniformity to increase the compactness of the material to be extruded, the extruder should have a circulating amount of 20% to fully utilize the efficiency of the extruder. The circulating material of the extruder consists of the coarse powder return after being classified by the dispersing classifier and the partial cake return after the extrusion. The feeding bin used in the extruder should have a steady flow function, and the feeding bin should be placed directly above the inlet of the extruder to ensure that the feeding of the extruder has a certain material pressure, so that the extruder is at Good working conditions.原石å库å™çŸ³äºˆåº“å°¸ååˆ Limestone extrusion system process electromagnetic vibration feeder Belt Conveyor single bag dust collector bucket hoist iron separator steady flow weighing bar brake extruder electronic belt feeder Chain Conveyor dispersing classifier lock gas discharge valve nuclear scale person extrusion machine materials should be iron removal treatment, and extrusion system design, but also the ball mill system to prevent iron pieces from entering the roll gap.
