The crushing ratio in the production line should be reasonable, so as to maximize the efficiency of the crusher. 4. The spring pressure should not be too tight. If the pressure is too high, the shaft breakage will occur. If the pressure is too small, the spring will jump frequently which affecting the normal operation of the crusher.

Work mode, the process of ore breakage by high pressure rolls was tested on a pilot stand of the Thyssen Krupp labora-tory for the purpose of determining the mid- and fine-crushing area. Then, the ore is milled by fine crushers KMD-3000T2-DP (6 crushers). The oversize product of screens GPKT-72U installed ahead of the crush-.Technical Information. The SMC Test is the most widely-used comminution test in the world for AG SAG Mills, HPGRs and Crushers. The SMC Test was developed to provide a range of useful comminution parameters through highly controlled breakage of rock samples. Drill core, even quartered small diameter core is suitable.

Be determined by the breakage characteristics of the ore under high pressure conditions. A finer size distribution would require a higher press force or, in some cases, a higher moisture content. Most of the products of the HPGR are generally discharged in the form of a flake of compacted material, however of a very fragile consistency.The 48 by 42-inch jaw crusher and smaller sizes are force-fed by an automatic high-pressure lubricator to the swing jaw, pitman, and main bearings as illustrated in Figure 1. A motor-driven pump forces the lubricant through pressure buildup cylinders and out to distributors which dispense a precise amount to each of the points on the bearings.

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.1 that can apply high pressure in a controlled manner to the ore confined in a cylinder. A steel cylinder of 100mm inner diameter, shown in Figure 2, was selected such that the maximum applied pressure was 55 MPa, estimated to be similar to the working pressure on hard rock within the breakage zone of a continuous HPGR.
