In terms of concrete crusher, if the supply voltage instability, first of all affected is concrete crushing plant crushing power, not enough power, then the system feeding and nesting in the process, it will cause an oversupply of equipment. On the one hand, the feeding mouth minerals into quantity big or small; on the other hand, exports of discharge device, screen - diminished capacity, is likely to cause material clogging.
Concrete crusher of Henan Hongxing Mining Machinery Co., Ltd. is broadly employed to break a variety of concrete into smaller sized sizes. A finish concrete crushing production line is made up of the next elements: vibrating feeder, major crushing gear (jaw crusher machine ), hammer crusher, secondary crushing gear (Cone Crusher or Effect Crusher), vibrating screen and so on. These concrete crushing machines can effectively make improvements to the productivity. Besides independent crushers, concrete crushing plant are also extensively applied by quarry operators.
Concrete crushing machine voltage instability, is likely to cause the whole machine belt conveyor happened tight or loose,belt failure, which in turn drive bearing out of action, and ultimately cause the device material clogging. This requires our workshop staff, which in ordinary work anywhere, anytime to observe the drive belt tensioner efforts to rationalize and control.
Concrete crusher machine voltage instability, may also lead to the eccentric shaft bushing, loose or fall off, eventually causing the rack near the bearing, causing the eccentric shaft is firmly stuck, the eccentric shaft can not rotate properly equipment suddenly interrupted work. Therefore, to ensure the stability of the operating voltage and the need to re-tighten the eccentric shaft bushing securely installed, if eccentric shaft adapter bushing damage to replace the eccentric shaft adapter bushing structure.

Rotary kiln belongs to building material equipment, and it can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials. Lime kiln is used for baking active lime and dolomite in the steel factory and ferroalloy factory.
During lime rotary kiln drying, should allow sufficient time, especially when changing the brick kiln , kiln because less material, and no kiln skin, so the skin and other refractory kiln heat evenly and there is a certain the heat content . In general, there is material in the kiln and kiln leather case and a cold kiln heating needs eight hours,short-term stop the kiln, in accordance with the corresponding five- cylinder outlet temperature rotating kiln drying time, change the brick kiln, heating time is usually ten six hours. And before ignition, all devices should be stand-alone test and linkage test, especially commissioning and trial production stage, to avoid heating up and then back on refractories disadvantage, namely the costs of oil and increased costs.
When the ignition drying kiln, generally the first use of light diesel oil , coal feeding system startup kiln, kiln drying ignition and initial feeding,try to use high volatile, low ash smaller, less water and coal fineness easy powder to keep the complete combustion of pulverized coal as possible to avoid the process of pulverized coal drying kiln and preheater kiln deposited slopes. And drying kiln temperature curve to follow strictly, this process should not be able to pay attention to the rotary limestone kiln too exhaust, otherwise there will be an illusion, five- cylinder high temperature, and the temperature inside the rotary kiln equipment is not high, so firing with low temperatures, no sufficient heat content in the exhaust by feeding a pulverized coal will not burn, long black attempting severe kiln see the fire, the chimney ESP black smoke, so that it is possible to feed fail, and it is very dangerous and harmful. Generally in the heating process rotary kiln control oxygen content of about four to six percent most appropriate.
