REMco

In the past, the limits on impact crushers have been their high cost to operate when the material is hard and abrasive. Historically, hard rock such as granites, quartzite and other materials with high abrasives content have caused severe wear on the crushing members of vertical shaft impact crushers making them prohibitively expensive to operate. REMco VSI RockMax crushers are autogenous vertical shaft crushing machines designed to operate as third stage crushers in the processing of all types of rock, ores and minerals. RockMax crushers can be operated in either open or closed-circuit. Closed-circuit operation is recommended in order to achieve the lowest net operating cost, best particle shape and the highest production. RockMax crushers are intended for producing crushed products between 1 ½- to 3/8-in.

Williams Crusher

Roll crushers are simple in design and construction, long lasting, economical and versatile, according to Williams Crusher. Roll crushing surfaces operate at a fixed distance apart, as opposed to the continually changing distances in a jaw or cone crusher. Product size is much more consistent. Both oversized pieces and fined are minimized. Wet, sticky materials are more easily handled. The rolls act as flywheels, contributing to smooth operation and efficient use of power. Roll crushers are low in profile and relatively easy to install. They can be fed with a minimum of headroom, or even choke fed. Adjustments are simple. Internal parts are readily accessible. Typical feed materials include bauxite, cement clinker, chalk, cinders, clay, coal, glass, gypsum, limestone, burnt lime, rock salt, sandstone, shale, sulfur ore, sea shells and sewer sludge clinker. Single-roll crushers, sometimes called lump breakers, can also be used for breaking frozen or agglomerated materials.
