Portable jaw crusher

Jun 22, 2017 there is a need for a compact, portable, underground hardrock crusher, with the major constraint on size being height. maximum crusher dimensions, including provision to feed the machine, should be about 7 to 9 feet high by 8 feet wide by any reasonable length. total throughput should be 100-300 tons per hour.

rollers or jaw crushers are employed in this situation. the jaw crusher is a rocks or lumps reduction machine challenges and problems. extensive research was carried out using existing data and during use, it wears in the bottom (closed side) of the jaw and flipping it over provides another equal period of use before replacement.

sep 02, 2019 output for mobile jaw crushers ranges from 100 to 1,500 tph depending on the model size and consistency of the feed material. while larger mobile crushers produce more aggregate faster, transport weights and dimensions may limit how easily the crusher can be shipped long distances.

the use of “guard” magnets to remove tramp metal ahead of the crusher is also common (chapters 2 and 13 chapter 2 chapter 13). jaw crushers are supplied in sizes up to 1,600 mm (width). for coarse crushing application (closed set~300 mm), capacities range up to ca. 1,200 t h −1.
