Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] Such as figure 1 As shown, a Portland cement production line includes a storage tower 1, a stirring device 2, a powder conveyor 3, a grinding device 4 and a cement silo 5 arranged in sequence. Among them, an aggregate conveyor 6 and an air chute conveyor 7 are arranged between the storage tower 1 and the stirring device 2 , and the milling device 4 includes a roller press 41 and a ball mill 42 arranged continuously.

[0037]When using the above-mentioned production line, first use the hoist (not shown in the figure) to transport the raw materials to the storage tower 1, and then weigh the raw materials in the storage tower 1, then use the aggregate conveyor 6 and the air inclined The trough conveyor 7 transports the granular raw material and the powdery raw material into the stirring device 2 .

[0038] Then use the stirring device 2 to fully stir th...

Abstract

The invention discloses a Portland cement production line, and relates to the field of cement production. The Portland cement production line comprises a storage tower, a stirring device, a powder conveyor, a grinding device and a cement bin; the stirring device comprises a stirring box and a box cover, and a rotating shaft is rotatably connected to the middle of the lower end face of the box cover; a plurality of sliding holes are formed in the box cover in a penetrating mode, the sliding holes surround the rotating shaft, wherein sliding rods are vertically connected into the sliding holes in a sliding mode; an impact rod used for abutting against the bottom wall of the stirring box is vertically arranged on the lower end face of the sliding rod, and a driving mechanism used for drivingthe sliding rod to reciprocate up and down is arranged on the rotating shaft. The cement stirring device has the following advantages and effects that raw materials in the stirring box are stirred byarranging the efficient stirring paddle, meanwhile, the sliding rod is controlled to drive the impacting rod to reciprocate up and down, the impacting rod is used for mashing the raw materials, thorough mixing and uniform mixing of the raw materials are achieved, and then the product quality of cement is improved.

Description

technical field [0001] The invention relates to the field of cement production, in particular to a Portland cement production line. Background technique [0002] Portland cement is a Portland cement clinker mainly composed of calcium silicate. It is a hydraulic cementitious material made of less than 5% limestone or granulated blast furnace slag and an appropriate amount of gypsum. [0003] Chinese patent CN105753346A discloses a dry cement production line, which includes a feeder, a No. 1 bucket elevator adjacent to the outlet of the feeder, and a raw material adjacent to the outlet of the No. 1 bucket elevator. silo, the dryer adjacent to the outlet of the raw material bin, the No. 2 bucket elevator adjacent to the outlet of the dryer, the homogenization bin adjacent to the outlet of the No. 2 bucket elevator, The mill system adjacent to the outlet of the homogenization bin, the No. 3 bucket elevator adjacent to the outlet of the mill system, and the powder classifier adj...
