The main machine consists of frame, air inlet volute, scraper, grinding roller, grinding ring, cover and motor. Auxiliary equipment includes jaw crusher, elevator, electromagnetic vibrating feeder, electric control cabinet, etc., which can be flexibly selected according to the on-site situation. Let’s talk about the working principle of Raymond mill.

After the material is crushed to the required particle size, the elevator sends the material to the storage hopper, and then the vibrating feeder sends the material evenly and continuously into the grinding chamber of the Raymond mill main machine. Due to the centrifugal force during rotation, the grinding roller swings outward and presses against the grinding ring. The scraper scoops up the material and sends it between the grinding roller and the grinding ring. The grinding roller rolls to achieve the purpose of crushing.

The fine powder after grinding is brought into the analyzer for sorting with the circulating air of the blower. The material with too coarse fineness falls back to the re-grinding, and the qualified fine powder enters the finished product cyclone powder collector with the air flow and is discharged through the powder outlet pipe to become the finished product.

In the grinding chamber of the Raymond mill, there is a certain amount of moisture in the material to be ground, heat is generated during grinding, water vapor evaporates, and the interfaces of the pipelines of the whole machine are not tight, so the external gas is sucked in, which increases the circulating air pressure, ensuring that the mill works under negative pressure. The increased air flow is discharged into the dust collector through the residual air duct and discharged into the atmosphere after purification.

Advantages of Raymond Mill

The entire Raymond Mill is a vertical structure with a relatively small footprint and strong system. It can form an independent production system from the rough processing of raw materials to transportation to powder making and final packaging.

Compared with other grinding equipment, the Raymond Mill has a high screening rate of up to 99%, which is generally unattainable by other grinding equipment.

The main transmission device of the Raymond Mill adopts a closed gear box and pulley, with stable transmission and reliable operation.

The important parts of the Raymond Mill are made of high-quality castings and profiles, with fine craftsmanship and rigorous processes, which ensure the durability of the entire set of equipment.

The electrical system adopts centralized control, and the grinding workshop can basically realize unmanned operation, and maintenance.

During the use of the mill, there should be a fixed person responsible for supervision, and the operator needs to have a certain technical level. Before the installation of the mill, the operator needs to undergo necessary technical training to make him understand the principle and performance of the Raymond mill and be familiar with the operating procedures.

In order to make the mill normal, the “equipment maintenance and safety operation system” should be formulated to ensure the long-term safe operation of the mill, and necessary maintenance tools, grease and corresponding accessories should be available.

After the Raymond mill has been used for a period of time, it should be overhauled, and the grinding roller, grinding ring, scraper and other wearing parts should be overhauled and replaced. The connecting bolts and nuts of the grinding roller device should be carefully checked before and after use to see if there is any looseness and whether the lubricating grease is sufficient.

When the grinding roller device is used for more than 500 hours and the grinding roller is replaced again, the rolling bearings in the roller sleeve need to be cleaned, and the damaged parts should be replaced in time. The refueling tools can be manual refueling pumps and grease guns.

Fineness adjustment, according to the size, hardness, moisture content, specific gravity of the material, the processing fineness is also different, the upper analyzer can be adjusted, high speed, high fineness, low speed, low fineness. Increasing the fineness will reduce the output accordingly. If it still does not meet the requirements, the fan speed should be adjusted, and the user can flexibly control it.

The scrap limit of the grinding roller and grinding ring is not less than 10mm.

When the Raymond mill stops, stop feeding first, and the main machine continues to grind, so that the residual abrasive continues to grind. After about one minute, the main machine motor and analyzer motor can be turned off to stop the grinding work, and then the fan motor can be stopped to blow away the residual powder.

Pendulum mill processed materials

The pendulum mill is suitable for huge capacity production and is widely used in grinding non-flammable and non-explosive materials under 7(the Moh’s hardness), such as quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, especially for slag, cement clinker, zircon sand, fly ash, carborundum, coal, etc.

Raymond Mill’s Requirements on Materials

➤Moh’s hardness below Grade 7

➤Moisture below 8%

➤Non-combustible and non-explosive

➤Feed size ranging from 40 to 400meshes

Calcium carbonate crushing processing, gypsum crushing processing, power plant desulfurization, non-metallic ore pulverizing, and pulverized coal preparation.

Applications: Metallurgy, chemical engineering, building materials, mining, pharmacy, cosmetics and other fields

After jaw crushers break large bulky materials to smaller ones, elevators work to send materials to the hopper. Then, by electromagnetic vibrating feeders, broken materials are evenly and quantitatively sent to the grinding chamber of the Pendulum mill.

After grinding, materials are blown away by airflow to the powder concentrator for classifying. Under the action of the impeller of the powder selector, materials that fail to meet fineness would be sent back to the grinding chamber to get another grinding while qualified powders would be collected by a cyclone powder collector and discharged from the bottom as finished products. And, after that, the airflow would go into the fan along with the air return duct at the top of the cyclone power collector. This system adopts a closed circuit and runs under positive and negative pressure.

Because materials have a certain content of moisture, heat generated during grinding may lead to air evaporation or swell in the grinding chamber so that the amount of airflow increases sharply. Besides, if the feed port and joints of pipelines are not sealed well, external air may intrude the grinding mill and lead imbalance of airflow. So, SBM arranges exhaust valves at the air outlet of the fan to induce redundant air into the bag filter. After purifying, the redundant air is discharged. This arrangement can achieve both the balance of airflow and the eco-friendly production.

The jaw crusher is a large crusher installed and receives no-load testing in the manufacturer’s workshop. However, it is disassembled into components for transport.

Do a good job with daily maintenance of the Pendulum mill.

Correct operation of the Raymond Mill is a must. Improper operation may cause damage to the Pendulum mill and shorten its service life, which may cause considerable economic losses due to long-term shutdown.

Control the feed standard of the Pendulum Mill.
