To construct a higher strength raymond mill, to enhance the grinding ability is an essential. The primary structure parameters of traditional raymond mill, for example mill roll diameter and thickness, the grinding ring diameter, spindle speed is invariable, grew to become limited to traditional. In the principle of mill, raymond mill grinding curler device by hanging at plum rack driven through the rotating movement within the spindle, under the act of centrifugal pressure grinding roll to roll grinding ring, within the act of friction spinning motion. The roll grinding in grinding ring moving rotating the primary mechanism of developing mill.

This analysis to high strength, raymond mill grinding capability to create effective must:

(1) boost the pressure curler

(2) powder grinding section of rotation of 1 week (curler height * grinding ring diameter)

(3) increase the prospect of connection with the grinding curler ring

(4) growing spindle speed.

The present quantity of raymond mill manufacturer in enhancing the grinding pressure fluctuation kongfu, for example using the pressure spring and also the hydraulic cylinder pressure method, however this method You will find both pros and cons. Traditional raymond mill curler suspension device can swing freely, can instantly avoid some bigger challenging for a pulverized material in rotary milling process, both to safeguard the grinding roll device from damage, bouncing effects occur and favorable towards the crushing, therefore the benefits and drawbacks to gauge the result of yield improvement in the final fineness. High strength Raymond Mill take:

(1) boost the grinding and grinding ring diameter

(2) finishing curler surface, to ensure that the curler and also the grinding ring beginning grinding condition, good contact, put on uniform

(3) growing spindle speed 7%~8%, within the premise from the host energy under constant enhancing the grinding efficiency, especially enhance ale ultra-fine powder processing.

Additionally, high-strength raymond mill has got the unusual powder collecting system. raymond mill with traditional single cylinder of huge diameter and short cone cyclone dust collector to attain solid gas separation, recovery of residual gas in fine powder with small diameter of cyclone dust collector. The stubby cyclone dust collector for that recovery of proper powder efficiency in excess of 325 meshes is low, once the powder fine to 1250 mesh, powder collecting efficiency is just 50%~55%, which clearly can't meet the advantages of processing superfine powder. High strength raymond mill switches into combined type small diameter lengthy cone efficient cyclone dust collector, it on 1250 mesh ultra-fine powder recovery efficiency can achieve above 95%, and also the recovery of 325 mesh powder rate as high as 99%. Residual powder collection while using pulse bag dust collector, having a draught fan air flow system that's in an adverse pressure condition, steer clear of the superfine powder leakage.
