Rod Milling Type Equipment/Rod Mill / Bar Mill/Rod Mill Sand Making Machine

Function introduction for rod milling sand-maker

Rod milling sand-maker is one of sandstone equipments widely used in building sand industry, used for processing and crushing of feldspar, quartz and ore. Barrel rotating with a certain speed, grinding element is precipitated after rising to a certain height under the friction force and centrifugal force. The stuff is stroke and grinded to make sand.

Details for overflow type rod mill, rod mill



The construction of overflow type rod mill and ball mill is basically the same. The difference is that the curvature of the tapered end rod mill is small, and with a smooth lining at the inner side, while the cylinder liner on the general use is not smooth; Larger diameter hollow shaft of discharge. The goal is to bar the rules in the mill in motion, will not skew, and thus against each other in the fall will not change when the bending; Big port of discharge in order to facilitate the installation of larger diameter rod and into the maintenance and inspection, while reducing the level of the slurry so that the slurry can be quickly discharged. The speed of the rod mill is low, the general speed was 60% to 70%; And the medium filling rate is lower, about 35% to 40%; Ore particle size is generally 25 ~ 30mm. If it is too big, Ore particle will make the bars skewed, and even cause bars bend and break when the machine is running. Meanwhile, the ore block over the General Assembly to stick with the large gaps between the rods, not easy to grind to a fine, resulting in the decline of yields. Ore is crushed and grinded by the 'line contact' when bars are sliding. Before the big ore is grinded, the fine one is hardly impacted by the bars. So overly broken is rarely happened. The granularity of the product is uniform, 1-3 mm generally.

So rod mill is suited for being used for the crushing and coarse grinding of the ore during the first stage of open-circuit grinding, especially for the treatment of brittle materials.
