The R-type Raymond Mill is an equipment used in the powder industry for non-metallic ore grinding. Raymond mill is a high-efficiency closed-circuit pulverizing equipment. Compared with Ball Mills, it has the advantages of high efficiency, low power consumption, small footprint, small capital investment and no environmental pollution.
Scope of application of raymond mill
It is widely used in the grinding and processing of mineral products in the fields of metallurgy, building materials, chemical industry, mining, etc. It is suitable for processing various non-flammable and explosive minerals with Mohs hardness below 7 and humidity below 6%, such as gypsum, talc, Calcite, limestone, marble, potassium feldspar, barite, dolomite, granite, kaolin, bentonite, medical stone, bauxite, red iron oxide, iron ore, etc.
Raymond mill configuration
The complete set of Raymond mill equipment includes: main engine, analyzer, blower, finished product cyclone separator, piping device, motor, etc. The auxiliary equipment includes Raymond mill, bucket elevator, electromagnetic vibrating feeder, electric control cabinet, etc. , users can choose flexibly according to the situation on site.
The grinding roller is tightly pressed on the grinding ring under the action of centrifugal force, so when the grinding roller and the grinding ring are worn to a certain thickness, the output and fineness of the finished product will not be affected. The replacement cycle of the grinding roller and the grinding ring is long, which eliminates the shortcoming of the replacement cycle of the wearing parts of the centrifugal pulverizer. The air flow of this machine is circulated in the fan-grinding shell-cyclone separator-fan, so it has less dust than the high-speed centrifugal pulverizer, the operation workshop is clean, and the environmental pollution is small.
The working principle of raymond mill
After the Raymond mill crushes the bulk raw materials to the required feeding particle size, the material is transported to the storage bin by the bucket elevator, and then evenly sent to the grinding cavity of the main machine by the electromagnetic vibrating feeder, and then enters the grinding chamber of the main machine. The material in the grinding chamber is ground between the grinding roller and the grinding ring. The ground powder is brought to the analyzer by the fan airflow for classification. The fine powder that meets the fineness requirement enters the large cyclone collector through the pipeline with the airflow, and is separated and collected. , and then discharged through the unloader to be the finished product. During the working process of the main engine, the blade system plays a very important role. It is located at the lower end of the grinding roller. During the co-rotation of the shovel blade and the grinding roller, the material is shoveled and thrown into between the grinding roller rings to form a padding layer. Grinding to achieve the purpose of milling.
Selection process:
After the material is ground, the fan blows the wind into the main casing to blow up the powder, and the analyzer placed above the grinding chamber is used for sorting. It enters the cyclone collector with the wind flow, and is discharged through the powder outlet after collection, which is the finished product. The air flow is returned to the fan through the return air pipe at the upper end of the large cyclone collector. The air path is circulating and flows under negative pressure. The increased air volume of the circulating air path is discharged through the exhaust pipe between the fan and the main engine, and enters the small cyclone collection. device for purification.
Raymond mill structure features
- 1. The whole machine is a vertical structure, with a small footprint and strong systemicity. It can be an independent production system from rough processing of raw materials to transportation to milling and final packaging.
- 2. Compared with other grinding equipment, the sieving rate is as high as 99%.
- 3. The main transmission device of Raymond mill adopts closed gear box and pulley, which has stable transmission and reliable operation.
- 4. The important parts of the Raymond mill are made of high-quality castings and profiles. The fine craftsmanship and rigorous process ensure the durability of the entire set of equipment.
- 5. The electrical system adopts centralized control, the grinding workshop can basically realize unmanned operation, and the maintenance is convenient.
Raymond mill maintenance and maintenance
- 1. During the use of the Raymond mill, there should be fixed personnel to take care of it, and the operator must have a certain technical level. Before the mill is installed, the operator must have the necessary technical training, so that they can understand the principle and performance of the mill and be familiar with the operating procedures.
- 2. In order to make the Raymond mill normal, a "safety operation system for equipment maintenance" should be formulated to ensure the long-term safe operation of the mill. At the same time, there must be necessary maintenance tools, grease and corresponding accessories.
- 3. After the Raymond mill has been used for a period of time, it should be overhauled, and at the same time, the wearing parts such as the grinding roller, grinding ring, shovel, etc. should be repaired and replaced. The connecting bolts and nuts of the grinding roller device should be carefully checked before and after use to see if If there is looseness, check whether the lubricating oil has been added enough.
- 4. When the grinding roller device is used for more than 500 hours or so to replace the grinding roller, the rolling bearings in the roller sleeve must be cleaned, and the damaged parts should be replaced in time.
Raymond Mill Price
The price of Raymond mill usually ranges from a few dollars to tens of thousands of dollars. Due to the different performance of different models of Raymond mills, the fineness of finished materials, motor power and output are also slightly different, so the equipment quotation is also Different.
