Spray water has obvious temperature reduction effect, but it also has side effect: it may cause the adhesion of raw materials. In this case, operators should pay attention to the water quantity.

This kind of crushing line features high crushing ratio, large capacity, easy to be adjustment, uniform production, simple structure, reliable function, easy maintenance, economical working, low energy consumption etc.

According to a fourth aspect of the invention, a method is implemented for increasing crushing capacity of mineral material in a jaw crusher or in a crushing plant, which jaw crusher or crushing plant comprises a crushing chamber and a pitman arranged in the crushing chamber, which pitman comprises an upper part comprising an upper supporting point for supporting the pitman in the body of the jaw crusher, and a lower part comprising a lower supporting point for supporting the pitman in the body of the jaw crusher through a toggle plate, and in the method, in a crushing event the pitman is moved, the lower part of which pitman comprises sidewalls and a honeycomb structure open to the crushing direction, which structure comprises one or more cross-sectional supports reaching from the first sidewall to the second sidewall for dividing the space between the sidewalls horizontally in parts.

Hummingbird Guinea Mining Corporation is a joint venture co-owned by the oil company Okapi Energy Group. The company approached to help them develop a quarry system with full mechanical and electrical engineering supervision.

A slight dissolution of calcites, suggested by a pH increase in the pore water of sediments treated with PCC and GCC (Figure 7b), did not result in P release, which may be attributed to Ca-PO4 compounds formation, as previously discussed. Lower pH observed in the pore water after incubation (Figure 7 b), as compared to initial conditions, (Table 2) could result from decomposition of organic matter in sediments. Dissolution of calcite is to be expected when the solution is undersaturated, whereas at the end of the experiment pore water was in the equilibrium state with respect to this mineral (Table 5), contrary to initial oversaturation recorded in the fresh pore water (Table 2). Lower saturation index after incubation was probably due to mixing of the sediments with lake water during resuspension, which limited availability of Ca2+ and HCO3- in the pore water, as lake water was characterized with much lower concentration of these ions (Table 2). Under equilibrium conditions, which were present in the pore water after incubation, dissolution of calcite (as well as crystallization) is possible [100]. Stronger dissolution of PCC as compared to GCC, indicated by higher pore water pH in treated sediments (Figure 7 b), is most likely related to smaller grain size of PCC [39].

The Mg# (Mg/(Mg + Fe2+)) was highest in the chromite found in the massive ore and decreased in the chromite found the disseminated ores (see Figure 4). The general trend is a decrease in the Cr#(Cr/(Cr +Al)) from chromite found in the massive ore to the disseminated ore types in the direction of the arrow in Figure 4.e., MCHR) versus that found in the disseminated type (PCMZ_MG and PCMZ_HG).The chromite chemistry was determined by analyzing chromite grains in thin sections using a CAMECA SX 100 electron microprobe. Variation in composition occurs between the chromite found in the massive type ores (i.
