  • Small occupying space and great performance

    Raymond Mill can form an independent production system from raw material crushing, grinding to packing. And through screening rate can reach 99%.

  • Good stability and high reliability

    Host transmission device adopts enclosed gear boxes and pulleys, leading transmission smooth and operation reliable.

  • Durable and long service life

    Raymond Mill is made of high quality materials, adopts sophisticated technology and rigorous process to ensure the durability of the equipment.

  • High automation

    Electrical system adopts centralized control, so the milling workshop can achieve unmanned operation.

Load the stuff for grinding evenly and continuously into the grinding chamber of the main frame. Due to the centrifugal force in rotation, the roller swings go outward and presses closely upon the ring. The shovel carries the stuff to the space between the roller and ring. When the roller rolls, the stuff is thus grinded. After being grinded, the stuff is to be routed to the classifier along wind belt of the blower and the rough powder will be put back to the grinder for regrinding. The fine powder flows into the cyclone collector together with air flow and is expelled from the powder output pipe as product. In the grinding chamber, since the stuff contains moisture to some extent, the heat generated during grinding makes the moisture evaporate; since the pipeline joints are not airtight, the external air is sucked in and the circulation air mass increases. In order to enable the grinder to work in negative pressure, the increased air flow is guided to the deduster and sequentially to the atmosphere after purification.

 Traditional of ore grinding mechanical more for speed rotary of horizontal mill, material by into material device by into material hollow axis spiral uniform to burst into mill machine first warehouse, the warehouse internal has ladder lining Board or corrugated lining Board, within loaded mill mine media for different specifications steel ball, tube body turned produced centrifugal force and material and tube body between of friction, will steel ball with to must height Hou, is cast falls State falls, on material produced heavy hit and grinding role to completed ore of crushed, reached requirements grain degrees of pulp and no reached requirements grain degrees of mine grain cannot separation, So in the resistance during exercise, motor power required is very large, high energy consumption, waste a great deal of power, and

 
Low efficiency. Has the applicant disclosed patent number 200620023504.6 for a vertical ore roll grinding machine, grinding ore crushing and screening machinery combination cohesion, improve work efficiency. During the process of application, due to the grinding roller is easy to wear and affect ground clearance, the need for frequent downtime adjustments, effects of grinding machines for continuous operation.
 
This product aims to provide a vertical ore was BEng modified roller grinding machine, grinding rollers manual adjustment, improvement of hydraulic control, in order to improve efficiency, ensure the quality of grinding. The technical solution for this product is done: the improved vertical ore roll grinding machines, rack set into the hopper, outlet, comprising motor and hydraulic pump drive grinding roller and grinding
 
Mill on roll grading combination set Yu machine frame Shang, grinding on roll set is ladder distribution, its features is: grinding on roll clearance can adjustable, each level grinding on roll set a fixed roll and a mobile roll, from Shang down of clearance gradually reduction/", and, grinding machine set hydraulic Station respectively drive machine frame Shang set of multiple hydraulic cylinder adjustment more on grinding roll of work spacing.
 
Improved vertical ore roll mill mentioned, the hydraulic cylinder is arranged in the rack side mobile grinding roller bearing, housings are connected with a sliding rack.
 
Improved vertical ore roll mill mentioned, the bearing is arranged the roof converge with the hydraulic cylinder.
 
Improved vertical ore roll mill mentioned, the adjusting nut is arranged between the grinding rollers also.? change from a vertical ore mentioned on roller grinding machine, wherein the grinding rolls per level tilt settings in the lower part of the pulp sieve, spigot into the channel to reach the pulp outlet, oversize roller grinding on into the next level.
 
Improved vertical ore roll mills described, wherein the two mill grinding roller of roller speed, direction, two mill grinding roller roll speed ratio is 1:1.8.
 
Improved vertical ore roll mill mentioned, the grinding at each level to roll the upper setting spray cooling pipes, mineral loading screen set red material on pipes.
 
This products improved of vertical ore on roll grinding machine, set motor drive pump and the grinding roll turned to completed ore of chronology, in chronology of process in the for grading filter, makes reached grain degrees requirements of pulp through sieve was rushed to pulp out material mouth, sieve Shang pulp entered Xia level grinding on roll continues to grinding; while hydraulic station control hydraulic cylinder timely adjustment each a level grinding roll of clearance, guarantee grinding quality, so can greatly improve efficiency, structure simple using convenient, application prospects is broad.
