Reasons for the low milling efficiency of Raymond mill

Frequently, customers will report that their Raymond mills are getting less and less efficient. Then the Raymond mill has a lower and lower rate of powder extraction. There are many reasons for this, but the main reasons are generally The factors of the process and the milling machinery have a great influence on the powder extraction rate of the milling machine. When the humidity of the material milled by the Raymond mill is large, that is, the moisture contained in the material is large, the material is easy to adhere in the mill, and is also easily blocked during the feeding process, resulting in a reduction in the milling ability.

Insufficient cleaning of Raymond mill, the number of process equipment for cleaning equipment is not enough (ie, there is no requirement for “three screens, two dozens, one stone, one wash material”), the materials are not clean, and the materials contain large amounts of impurities.

The technical conditions of the Raymond mill are not good. The technical conditions of the mill mainly refer to the grinding roller (the grinding head of the cone mill and the grinding disc of the steel mill). The use time is too long, the grinding teeth are blunt, so that the grinding The effect is greatly reduced. The quality of the tooth profile of the surface of the roller of the roller mill is not up to the requirements, and the inclination or the arrangement of the pitch of the roller is not installed. The tooth profile of the grinding roller is improperly selected.

The annual emissions of fly ash, in the hundreds of millions of tons, as industrial waste discharged from power plants, the treatment has become a big headache for many companies. After research, due to its special physical properties, it can be widely used in the environmental protection industry after being processed by the mill.

In the same way, industrial solid waste such as slag, water slag and steel slag has also been recycled reasonably. After the processing of Raymond Mill, these wastes have not only been treated in terms of environmental protection, but also have a more reasonable application in the comprehensive utilization of resources.

Raymond mill is widely used in the grinding of mineral materials in metallurgy, building materials, chemicals, mining and other fields. According to the fineness of the material to be milled and the fineness of the material to be discharged, the mill can be divided into Raymond mill, pendulum mill, high pressure suspension roller mill, high pressure micro powder mill, and overpressure trapezoidal mill. Machine, three-ring medium speed mill, six types of mills.

The grinding machine generally has a matching production line. The grinding production line is mainly composed of crushing equipment, lifting machine, silo, feeder and mill.

Raymond Mill production line process: After the bulk material is crushed to the required particle size by the jaw crusher, the material is sent to the silo by the hoist, and then uniformly fed into the main mill room by the vibrating feeder continuously for grinding. The grounded child is taken away by the fan airflow. After being classified by the analysis machine, the fine powder conforming to the fineness enters the large cyclone collector through the pipeline, and is separated and collected, and then discharged into the powder tube to be the finished powder. The airflow is then drawn into the blower by the return air duct at the upper end of the large cyclone collector. The whole airflow system of the machine is closed and circulating, and it circulates under positive and negative pressure conditions.

Operation sequence of the mill production line: start: hoist, crusher, analyzer, fan, main machine, feeder. That is to start the bucket elevator, start the jaw crusher, and store the materials in the warehouse, start the analysis machine, start the blower (empty load start, wait for the normal operation, then load, start the host, start the electromagnetic vibration immediately after starting the host Feeder. At this point the grinding work is the beginning.
