Brief introduction: limestone is the main raw material for cement production. In order to reduce the cost, general manufacturers generally purchase unprocessed massive limestone directly, and then need to crush the limestone by a jaw crusher and then use a hammer crusher or a cone crusher for crushing. Medium-fine crushing is usually an essential process step in cement plants, even if the cost of raw materials is not considered. As limestone still has certain hardness, the crusher for medium and fine crushing is used for a long time, and the abrasion loss is larger. Wear part replacement is a major part of equipment maintenance. The difficulty of limestone crushing is reduced, the service life of equipment is prolonged, and the method is a necessary way for reducing the production cost of cement. Therefore, in the prior art, the tail gas of the rotary kiln is mostly adopted to carry out preheating treatment on the limestone so as to reduce the crushing difficulty of the limestone.

Preferably, the hot air pipe is arranged on the side wall of the preheating tower, the hot air pipe is communicated with the interior of the preheating tower, one end of the hot air pipe is provided with a wind shield sheet, the wind shield sheet is arranged in the preheating tower, and the wind shield sheet is arranged obliquely upwards.
Preferably, one end of each conveyor belt is close to the inner wall of the preheating tower, the conveyor belts are arranged in a staggered mode, and at least three conveyor belts are arranged.
And optimally, an air port is arranged above one side of the preheating tower, the negative pressure fan is connected with the air port, and a dust-proof filter screen is arranged on the air port.
The utility model discloses an it is whole beneficial effect: a cement raw meal crushing device is characterized in that a preheating tower is arranged above a crushing unit, a conveyor belt and a hot air inlet are arranged in the preheating tower, limestone entering the preheating tower stays in the preheating tower for a longer time and is in full contact with hot air, and a negative pressure fan is arranged above the preheating tower, so that the hot air naturally upwards and is in full contact with the limestone;
the effect of the synergistic effect of multiple technical characteristics: limestone is conveyed downwards by a conveying belt in the device, a negative pressure fan above the conveying belt enables the preheating tower to keep a negative pressure state, more hot air is conveyed upwards, and the limestone and the hot air are in more sufficient contact and have better preheating effect by combining the limestone and the hot air;
compared with the prior art, the difference technical effect is: the device improves through the structure to preheating tower inside, makes hot-blast and limestone contact more abundant, and the limestone obtains fully preheating, improves cement raw material breaker's crushing efficiency greatly.
