Raymond mill
- Product Introduction: A Raymond mill that is highly complete and can independently form a production system.
- Capacity: 3-22T/h
- Applications: Huston Raymond Mill can grind various non-flammable and explosive mineral materials with Mohs hardness below 9.3 and humidity below 6%; such as cement (uncooked clinker), talc, feldspar, quartz, slag, mica, calcite, limestone, barite, potassium sulfate, bentonite, and more than a thousand kinds of materials.
- Product Improvements: The unique air self-circulation system, coupled with a mature dust collector, implements the environmental protection concept to the end. The grinding roller assembly is connected through a tie rod and a high-pressure spring, and the force generated avoids the loss of equipment by large pieces of material. The elastic connection between the host machine and the powder separator reduces vibration and noise and increases the service life of the equipment.
Advantages and Features
- The grinding roller assembly is connected through a tie rod and a high-pressure spring, and the force generated avoids the loss of equipment by large pieces of material. The elastic connection between the host machine and the powder separator reduces vibration and noise and increases the service life of the equipment
- The grinding mill integrates crushing, drying, grinding, and graded transportation into one, so it has a simple system and a compact layout, covering an area of about 50% of the ball mill system, and can be arranged in the open air, so it can significantly reduce investment costs
- The grinding roller device adopts an overlapping multi-stage seal with good sealing performance
- a unique air self-circulation system, coupled with a mature dust collector, implements the environmental protection concept to the end
- The high-density and high-precision impeller device increases the output of finished products by more than 50% under the same power. The efficient and energy-saving centrifugal induced draft fan greatly improves the efficiency of the induced draft fan. The convenient and fast impeller adjustment device improves the accuracy of the finished product.
Working Principle
After the large pieces of material are crushed to the required particle size by the jaw crusher, the materials are sent to the storage hopper of the Raymond mill by the elevator, and then the materials are evenly and quantitatively continuously sent into the main milling chamber for grinding through the electromagnetic vibrating feeder. The ground materials are sent into the powder separator by the air flow of the fan for classification. Under the action of the impeller of the powder separator, the materials that do not meet the fineness requirements fall into the grinding chamber for re-grinding. The materials that meet the fineness requirements follow the air flow through the pipe and enter the cyclone powder collector for separation and collection. The finished powder is discharged through the discharge device. The separated airflow enters the fan through the return air duct at the upper end of the cyclone powder collector.

Case Study
In a certain dry grinding process, the autogenous grinding mill selected by the ore concentrator suffered from serious equipment wear, low efficiency, and the discharged particle size was larger than the expected particle size. In this case, the ore concentrator chose a Raymond mill. Raymond mill is an ideal equipment for dry grinding. It is more efficient than ball mills, consumes less power, has less wear and tear, and discharges materials uniformly. The most important thing is that it integrates crushing, grinding, and classification. It has a simple system, an impeller device, and a small discharge particle size. It improves production capacity while also reducing investment costs, and customer satisfaction is high.
