We are an ISO 9001:2000 certified company. Our primary jaw crushers are ideally suitable for crushing of bigger size hard granite stone, iron ore, black trap rock, river gravel, lime stone and coal. These are used to reduce the blasted stone, large boulders or recycled materials to a suitable size for conveying and further processing. They consist of feeders with hoppers to receive surge loads and give a regulated feed to the jaw crushers. The reduced size material is collected on conveyors and carried to convenient transfer points for further processing. These primary plants are also available on single unit structure of a portable plant with structural supports in place where permanent structures are not desirable. Portable plants are available in conventional or low profile models. Our horizontal shaft impactor (HSI) impact crushers are manufactured in several sizes. It is used where maximum reduction in one crushing stage is desired. The use of special alloy hammers such as hi-chrome, makes these impactors practical in hard stone as well as in low abrasion operations. Our impact crushers are used in both primary & secondary crushing applications of aggregate, and in recycle crushing of reinforced concrete, asphalt & other construction & demolition debris. Our road portable conveyors can be set up and torn down easily. These are available in 24" to 48" widths and up to 125' lengths. They are suitable for use in portable systems for concrete and asphalt recycling, aggregate crushing, sand & gravel, material processing, demolition operations, mining & other bulk handling operations.
