Jaw crushers are usually preferred as primary crushers in small installations due to the inherent mechanical simplicity and ease of operation of these machines. additionally, jaw crushers wearing parts are relatively uncomplicated castings and tend to cost less per unit weight of metal than more complicated gyratory crusher castings.Oct 19, 2017 manufacturing of m-sand 6. primary crushing the raw mined material is brought to the crusher plant by rear-dump haulers or front-end loaders. primary crushing reduces this run of mine rock to a more manageable size. the two types of primary crushers are the compression jaw crushers and gyratory crushers. jaw crushers 7.Impact crushers may be used as primary, secondary, or tertiary crushers. despite having a somewhat higher operating cost than other crushers, they tend to produce a more uniform particle shape. impact crushers usually will benefit the aggregate better than compression crushers, and Impactors are often used as a cost effective alternative to jaw and cone combination plants as they have a good level of reduction and product shaping for many applications. powerscreen impact crushers are designed to excel as primary impactors, taking large feed May 06, 2021 net profit from m sand crusher per day . to estimate net profit in a day, we have to deduct the cost of raw material, rs 110000, and daily expense, rs 13269, from this total sale revenue. by this calculation, it is estimated that the net profit in day from m sand p sand crusher Crushed stone plants a crushed stone plant differs somewhat from a sand and gravel plant. raw material, of various sizes, is brought from a quarry, to a primary crusher, by haul units. some primary crushers are fed by wobblers, which are chain driven conveying systems, with eccentric rollers.
