Raymond Mill

About Raymond Mill:

Raymond Mill Features & Benefit

• The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to grinding and packing is an independent production system.
• Compared with other milling plants, its passing ratio achieves 99%, this is what other mill can not reach.
• Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.
• The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.
• Firstly, most raymond mills are used for handling with some frivolous material, but with the deepening of understanding and the superiority of the crushing steel, all kinds of raymond grinding mills are developed quickly and used wider and wider. Even to the entire scrapped cars and household appliances, processed with appropriate conveyor and sorting equipment, the composition of scrap broken lines can be easily finished ,so it is no need to dismantle of scrapped cars and household appliances and it is easily to product and process automatically to get pure crushed steel, non-ferrous metals and non-metallic materials available.

Raymond Mill Working principle:

Firstly, raw material is crushed by jaw crusher to the size required, and then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind. After this, the ground stuff is carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The airflow system is closely sealed up and circulated under condition of negative and positive pressure.

High Pressure Suspension Mill VS Raymond Mill

Raymond mill is the earliest model of raymond mill series.

High pressure suspension grinding mill is the second generation of raymong mill series.Based on raymond mill ,pressure spring is added on high pressure suspension grinding mill .Thus it increases the grinding efficiency by enhancing the grinding pressure.

MTM trapezium mill VS Raymond mill

Raymond mill is the earliest model of raymond mill series.

MTM medium speed trapezium mill is the third generation of raymond mill series.Compared with raymond mill,MTM medium speed trapezium mill adopts the ladder-shaped rollers and ring which can improve crushing efficiency greatly.Also, the pressure springs have balancing and pressurized function,and the elastic connections reduce vibration and keep balance.If you take more understanding of MTM medium speed trapezium mill,you will find it more excellent than raymond mill.

MTW series european technology trapezium mill VS Raymond mill

Raymond mill is the earliest model of raymond mill series.

MTW SERIES EUROPEAN TECHNOLOGY TRAPEZIUM MILL--the latest grinding equipment, with its own knowledge patents, have reached modern advanced level in the world.It adopts much more latest patented technology ,such as bevel gear overall drive,inner automatic Thin-Oil lubricating system,arc air channel,cambered shovel with renewable edge,separated cyclone, no resistance snail shell,etc.This mill absorbing the European advanced technology and many engineers’ ripe experience, combining the actual requirement and proposal of our 9518 customers’, have been developed on the basis of our professional engineers’ hard researching.MTW SERIES EUROPEAN TECHNOLOGY TRAPEZIUM MILL is the latest improved product on the basis of MTM medium speed trapezium mill,so it will exceedthe latter in more factors.

The repair and maintenance of Raymond mill

1.During the application of the this grinding mill, some personnel shall be arranged to take responsibility of management. The operators must be qualified with the required technical knowledge. Before the installation of the grinding mill, the persons related to the operation should receive technical training and fully understand the operating principle, performance and regulations of it.
2.In order to guarantee the raymond mill in a normal working state, a Safety Operation System for the Maintenance of the equipment must be established. Only in this way can this grinding mill be guaranteed to have a long-term and safe operation. Meanwhile, it is necessary to have the required repairing tools, lubricant and grease, spare parts and accessories.
3.After some period of running, the raymond mill should receive an examination and repairing. The components vulnerable to worn out, such as grinding roller, grinding ring, relieving tool etc. should be repaired or replaced. Before and after the operation, a careful examination should be carried out for the connecting screws, bolts and nuts on the grinding rollers so as to find whether they are loose or sufficiently lubricated.
4.When their application time surpassing about 500 hours, all the rolling bearings in the roller sleeves must be cleaned, and the damaged parts should be replaced. The oiling tool can be either a manual oiling pump or grease gun.
