The iron ore processing for bulk materials

A continuous soft rock process starts with a bucket wheel excavator. The mined material, overburden or other material, such as lignite, is then transported from the pit on conveyors. Overburden material is typically dumped on the other side of the pit across from the mine face.

The bucket wheel excavator, through an installed conveyor system, discharges overburden into the receiving chute of a hopper car. To minimize distance and height issues, a beltwagon can work as a mobile link to the mobile hopper offering greater flexibility. A conveyor system, specially adapted to the topographic conditions mobile cone crusher plant, transfers the material around the pit to a crawler-mounted spreader which discharges the waste material in the dumping area.


Shanghai JOYAL Machinery sand production line has realized automatic control of production, and the production scale can be easily controlled to configure the best and most economical production line. The construction of buildings needs a large amount of sand, but their requirements for sand quality are not the same. The major difference between artificial sand and natural sand lies in the rough appearance and non-performing shape. Rough appearance and unrounded shape cause adverse effects for the mobility of concreting, which will result in voids into concrete. And it can be said that the sand maker directly impacts the quality of the project. Therefore, the quality of the artificial sand should be mainly decided by rough appearance and circularity of the sand. In addition, limitations of raw materials of artificial sand and other synthetic materials must be seriously faced by the manufacturing industry and construction enterprises.


The sand production line, also known as the sand and gravel production line, is mainly composed of mobile rock crushing plant, portable crushing plants for sale (Sand making machine), vibrating screen, sand washing machine, belt conveyor and other equipment. The Sand Maker is a kind of new type calcite crusher equipment with higher working efficiency and low running cost. It is successfully designed and developed by the principle —- the combination of “stone hits the stone” and “stone hits the iron”. Aiming at the situation that the natural sand is diminishing day by day, Shanghai JOYAL Mining Machinery Co., Ltd. successfully developed the sand production, which is dedicated to the production of artificial sand, with the refined grain shape, high efficiency, adjustable fineness modulus and low cost. The gold ore crushing plant is used for the secondary crushing, and then uses the sand maker to adjust the sand particle size, which solves the problem that only use the impact crusher, the final products is poor in the particle size.
