A control system for use at a dump location having a plurality of dump sites is disclosed. The control system may have a control module associated with a mobile machine and a worksite controller. The worksite controller may be configured to receive a signal from the control module indicative of the mobile machine crossing a boundary at a dump location, and assign a travel route for the mobile machine based on the signal. The travel route may include a travel segment on a common entrance row, a first single-use path from the common entrance row to a particular one of the plurality of dump sites, a second single-use path from the particular one of the plurality of dump sites to a common exit row, and a travel segment on the common exit row. The worksite controller may be further configured to communicate the travel route to the control module as the mobile machine moves toward the dump location.

An improved absorbent composition based on the natural hydrocoUoid material treated with porous aluminum silicates quickly absorbs an aqueous liquid and retains the liquid even under external pressure. The improved composition has liquid absorption and retention properties comparable to conventional SAPs, e.g., rapid, simple hydration with stable viscosity maintenance and aqueous liquid retention over wide ranges of temperatures, externally applied pressures, and salinity concentrations. This composition naturally breaks down into simple sugar molecules within several months after hydration from normal use. The released simple sugar molecules provide a great carbon source for microbes, creating an environment that promotes the breakdown of other biodegradable materials in the disposed diaper and landfills. The absorbent composition improves the performance of many aqueous liquid absorption products, such as personal hygiene products, for the absorption of significant amounts of moisture, bodily fluids or other aqueous solutions, when the composition is used as an absorbent in the products

The invention discloses a beneficiation production system of lean magnetite, and belongs to the technical field of beneficiation. The beneficiation process comprises the steps of coarse crushing, middle crushing, magnetic separation and transfer; and a middle crushing device is arranged in front of an ore mining field, the coarse crushing, the middle crushing and the dry type magnetic separation work are directly carried out on the ore mining field, the purpose of early throwing and early discarding of the tailing waste rock is achieved, the grade of rough concentrate is improved, and the oretransportation amount is reduced, the ore transportation cost is reduced, the service life of a belt and a funnel lining plate of the magnetic separator is prolonged, so that the operation cost of a mine is effectively reduced. The production system comprises a coarse crusher, a screening machine, a middle crusher, a magnetic separator, an adhesive tape conveyor I and an adhesive tape conveyor IIwhich are sequentially arranged in an ore mining field according to a production line, wherein the adhesive tape conveyor I is used for transporting the tailing waste rock which is subject to the magnetic separation to a waste dump, and the adhesive tape conveyor II is used for conveying coarse concentrate which is subject to the magnetic separation to a subsequent process. The area of mining ironore is expanded, the system is especially worthy of popularization and application for our country mineral facts taking the lean iron ore as a main body.

The invention discloses a shield sludge cleansing / recycling / reusing system and method. The system comprises a slurry mixing pool (1), a mixer (2), a cyclone desander (3), a slurry storage tank (4), a mortar mixing station (5), a waste dump (6) and a pipeline. The shield sludge cleansing / recycling / reusing system and method have the advantages that the sludge generated in shield construction is cleansed and recycled so as to be reused as the raw material of shield synchronous grouting, so that the problems of large sludge waste amount and pollution on environment in the shield construction in the past and the problem of large consumption amount of raw materials such as shield synchronous grouting bentonite are solved, and therefore, the utilization amount of the bentonite is saved, the pollution on the environment caused by the waste sludge is reduced and the shield construction cost is also decreased. The system and the method provided by the invention further are characterized in that slurry prepared according to the slurry preparation ratio according to the invention is used for synchronous grouting in the mortar mixing station, the performance and the quality of grouting are the same with the performance and the quality of grouting by using the bentonite slurry, and the requirements of the shield construction can be met.
