[0004] "A Limestone Powder Preparation Process" (Chinese Patent, Patent Application Publication No. CN 111871580A) discloses a limestone powder preparation process, which uses a limestone powder preparation device that introduces limestone into the The crushing unit crushes, grinds, and then sieves to obtain powder. The preparation of this method needs to meet the fineness requirements before it can be milled. Over-grinding is prone to occur, and the finely ground material is easy to form a cushion layer, which hinders coarse grinding. The material is further ground, which greatly reduces the grinding efficiency and increases power consumption

Embodiment
[0030] Such as Figure 1-2 A kind of limestone differential preparation method shown, adopts a kind of limestone powder Raymond mill powder processing equipment, limestone powder Raymond mill powder processing equipment includes feeding device 1, grinding and classifying device 2 and limestone powder collecting device 3, adopts above-mentioned When limestone powder Raymond mill milling processing equipment is milling, the specific steps are as follows:
[0031] S1. Preparatory work: the limestone block is sent into the mill through the feeding device;
[0032] S2. Fine powder grinding and classification: the limestone block is ground into powder in the mill, the fine powder and particles are classified, and the particles are returned to the mill;
[0033] S3. Fine powder collection: collect the fine powder separated in the grinding and classifying equipment 2 .
[0034] The feeding device 1 is installed and fixed above the side of the grinding and classifying device 2, and t...

The invention discloses a limestone differential preparation method, which adopts limestone powder Raymond mill powder processing equipment, and the limestone powder Raymond mill powder processing equipment comprises a feeding device, a grinding and grading device and a limestone powder collecting device. The method comprises the following specific steps: S1, preparation operation: feeding limestone blocks into a grinding machine through a feeding device; s2, fine powder grinding and grading: grinding the limestone blocks into powder in a grinding machine, grading the fine powder and particles, and leaving the particles back into the grinding machine; and S3, fine powder collection: fine powder separated from the grading equipment is collected, and the fine powder continuously passes through an air screen along with airflow and is sent to a cyclone powder collector for collection, so that the over-grinding phenomenon can be prevented; limestone powder which does not meet the granularity requirement is blocked in the classifier and falls back to the main machine of the Raymond mill to be finely ground again, repeated feeding can be avoided, and the grinding process is shortened.
Description
Technical field: [0001] The invention belongs to the technical field of limestone powder preparation technology, in particular to a limestone differential preparation method. Background technique: [0002] Limestone powder is a powdery material that is made of limestone of a certain purity and processed to a specified fineness after grinding. In my country, limestone has the advantages of wide distribution and low price, and is widely used in cement, lime and other industries. Among them, the fine grinding of limestone and reaching a suitable particle size can be used in the construction industry or other industries. Therefore, the fine grinding process is the core factor of its use. [0003] "A Limestone Dry Grinding Processing Technology" (Chinese Patent, Patent Application Publication No. CN111450942A) discloses a limestone dry grinding processing technology, which uses a limestone dry grinding processing equipment. Preliminary crushing of large pieces of limestone, and...
