Blake type jaw crusher

Americans EW Blake (Black) designed and manufactured the world's first jaw crusher. Its structure in the form of dual-elbow-plate (simple oscillating type) jaw crusher.

The crushing machine is the modern steam engine and electrical power machinery, etc., after a gradual improvement and extension have created. Appeared in 1806 with the steam-driven roller crusher; in 1858, the United States, Blake invented the broken rock jaw crusher; in 1878, the United States has developed with continuous action cycles crusher broken, its production efficiency is higher than for intermittent Broken action jaw crusher; in 1895, the United States, William invented a low energy impact crusher.

These ideas were given concrete form in a new line of all-steel Blake type jaw crushers, with frames of welded design, and several interesting and important refinements in mechanical details, including an improved system of lubrication.

Fig. 4 shows a diagram of the crushing chamber in one of the new type crushers. This diagram covers a machine of the same receiving-open. ing size as the standard type on which the two preceding diagrams were based. A brief comparison will indicate why the new crusher has distinctive performance characteristics.

Mining Equipment In Brazil

Brazil mining equipment includes Brazil crushing equipments, Brazil grinding equipment, Brazil conveyor, Brazil screening and feeding equipments etc. According to our mining experience, mining equipments are used widely in ore processing plants, minerals mining industry. First, we need mining crushing equipments for crushing stage, and then, we use grinding machines for grinding crushed materials to get small size.

The minerals sector employs about 4% of the total workforce (approximately 650 000) of Brazil. This excludes the estimated 1 million “garimpeiros” or artisinal miners active in Brazil. Job losses continue to occur as a result of privatisation and joint venture activities.
