Ring And Roller Mill

1. In order to suit the mineralogical characteristics of wollastonites, vortes cutting and rolling methods are adopted as the main forces for mechanical grinding so as to protect the crystal formation of the wollastonites. The machine has a high length to diameter ratio (L/D=12-25:1).
2. The working gaps of the grinding accessories/devices are adjustable, so that needle-shaped wollastonite powder of different fineness can be produced (d97=13-220 m). When the grinding accessories/devices are worn, the correct working gaps can be mained by adjusting the relevant spacers so that mot only is the operational lift of the grinding accessories/devices extended, the quality of the product is also guaranteed.
3. The equipment has buit-in low-speed stage separation device(s), able to meet the required product fineness and to avoid over grinding of the product in the form of breakage of the "needles".
4. The use of electro-magnetic vibration feeding forms part of the automatic feed control system. This is responsive to the conditions of the grinding and blower motors, guaranteeing consistent feeding and best efficiency.

1. Our design idea is market-oriented and its goal is to increase customers satisfaction. Design according to the customers special requires. Achieve the perfect combination of rational investment and lower cost.
2. According to related national standard strictly, we guarantee stable and reliable product quality with superb technique and technology.

Vertical roller mill roller body wear
Reasons: 1. Subject to frictional pressure between roller, material reaction force, friction between material and roller liner
2. The mutual effect of the material grinding angle on the shear stress of the grinding roller, the hydraulic system pressure of the roller mill and the apparent compressive stress of the vertical mill
Fault: Once there is a matching clearance, impact collision will occur between the body and the lining, which will increase the wear between the body and the lining. In severe cases, the lining will crack or even break, causing the lining to fall off, the machine is damaged, especially the deceleration. Damage to the machine, causing a vicious incident.
Solution: Developed countries such as Europe and the United States use polymer composite materials for rapid repair of vertical roller wear, among which the Fushui Blue series is relatively mature. The material is satisfactorily solved with its excellent mechanical properties and good plasticity. It not only prolongs the service life of the equipment, improves the productivity, but also avoids the secondary possibility of the problem, and avoids the additional downtime of the shutdown, and escorts the safe and continuous production of the enterprise.
Vertical roller mill wear chamber wear
Reason: 1. There is a gap between the bearing and the bearing chamber
2. Bearing heating will lead to bearing sintering
Solution: 1. Traditional soldering brush plating method, there are certain drawbacks: repair welding will cause thermal stress, bearing material damage, severe deformation or even break; brush plating pollution is heavy, and coating thickness is limited, application Subject to greater restrictions.
2. The processing of polymer composite materials can ensure the matching of the repaired parts and the matching parts to the utmost extent, and avoid the secondary wear caused by the increase of the gap.

Product descriptions about YGM8314 Raymond Roller Mill:
Clirik YGM8314 Raymond grinding mill, Raymond mill is suitable for processing various non-flammable and non-explosive mineral materials with Mohs hardness less than 9.3 and humidity less than 6%, it is widely used in the fields of metallurgy, construction, chemical industry, mining, highway construction etc,. The granularity of the finished powder size can be adjusted between 50 and 325 mesh (315-45 micron). Examples of processing materials include quartz, feldspar, barite, calcite carbonate, limestone, talc, ceramic, iron ore, carborundum, bauxite, rock phosphate, coal and other materials, total about 400 kinds of materials.

Features of YGM8314 Raymond Roller Mill:
YGM8314 Raymond grinding mill, Raymond mill has the similar working principle as High pressure suspension grinding equipment, but its grinding device is fixed with 1000-1500kg pressure springs. When the machine works the grinding roller, which under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure is 1.2 times higher than that of High pressure suspension grinding equipment given an identical condition and its capacity increase 20% to 30%; When the grinding roller and grinding ring, stable capacity and fineness are guaranteed.

Operating Principle of YGM8314 Raymond Roller Mill:
Big materials are crushed by jaw crusher to the required particle sizes, and carried by bucket elevator to the storage hopper, and are fed evenly and continuously by vibrating feeder into the main unit for grinding. The grinded powder are carried by the airflow from the blower to the classifier to be classified, the particles which meet the fineness enter cyclone collector through pipe, and are separated and collected there. They are discharged at the discharging valve to become finished products; the airflow is sucked to the blower by return pipe on the top of cyclone collector. The whole airflow system is a sealed circulation, and is circulated under positive and negative air pressure.
