Gong Yifu into the structure and design of mechanical plant material sealed feeder 
 Discharger of vertical material sealed by material sealing, automatic control and dust is composed of three parts, material sealed in part by the size of the population transition downpipe, the composition of the material sealed tube and choke. 
 Material sealing material sealed part of the main design quality directly affects a material effect. Material sealed tube diameter of the kiln clinker particle size decisions, including the percentage of the maximum size of the particle size and large content. Conditions of the plant equipment, raw materials of nature and the firing of the operating characteristics of the size composition of clinker are also different. Tower machine kiln and roller pendulum roller machine kiln kiln clinker particle size is small, the disc machine kiln and reciprocating machine kiln kiln clinker particle size. No eccentric or eccentric tower head unloader, prone to flake chunk. Clinker particle size and unloader wear, especially the roll, the swing roller machine kiln. The new kiln unloading machine, smaller particle size of clinker from the kiln, roller tooth wear, clinker particle size will increase. In addition, the flux of mineral excess, method of operation in the deep end of the fire, will be resorted to an increase in kiln cooked shaking chunks. 
 The throttle is the material seal discharger to control the feeding amount of the implementing agencies. Either manually operated or automatic control of the feeding amount of the shaft kiln should choke restraint. General feeder and conveying equipment, can be used as the material sealed choke feeder, this choke should have the condition: (1) be able to adapt to a uniform vertical kiln discharge requirements, ease of large pieces of clinker discharged, able to adapt and limit the leakage of small yellow powder material. ② production, suitable for machine Kiln Grate the actual maximum discharge requirements. (3) can withstand the shaft kiln out of the kiln, the clinker high temperature. (4) to facilitate automatic control. (5) Ease of collecting processing. 
 Conveyor throttling, can save a device to simplify processes, a high degree of conservation. 
 General feeder throttle, the electric vibrator. Meet the five requirements, the following four advantages: can ① The instantaneous continuous OFF, continuous amplitude modulation, to meet the control requirements. ③ start and stop fast, responsive, automatic control. ③ there is no friction, no lubrication. The ④ general shaft kiln cement plant can be made. The drawback is the poor adaptability of the yellow powder.
