The invention discloses a pipeline transportation means for alumyte. First, placing a raw material crusher on the alumyte mine, alumyte, lime and water are feed in the raw material crusher proportional. The water cut of the aqueous size after grinding is 45-55%; Secondary, sending the aqueous size to the aluminum ore size box in the alumina manufacturer using the pump amd the pipe; and then press with a pressing filter. The water-content coefficient of the filter cake after press is lower than 20%, And then send the filter cake to the aluminum ore bunker stored and dry the water-content coefficient of the filter cake to lower than 10%. The invention can reduce program investments substantial, cost down transport cost and improve the work environment of the alumina manufacturer.

The invention discloses a water cutting geological rock sample machining device and method. The device is mainly formed by universal wheels, a lower box, an upper box, a three-axis linear sliding table, a water cutting system and an integrated control box, wherein an ultrahigh pressure water jetting generation system is arranged in the lower box, a water purification device, a water tank and a working rack are arranged in the upper box, the three-axis linear sliding table is located above the working rack, the water cutting system is located on the three-axis linear sliding table, and the ultrahigh pressure water jetting generation system is connected with the water cutting system. According to the water cutting geological rock sample machining device and method, during rock sample cutting machining, manual intervention and operation are not needed, the effects of heat, the size, stress concentration and the like existing in a traditional machining device and method can be better overcome when rock samples are machined, and a good foundation is provided for improving the accuracy of measurement results. The water cutting geological rock sample machining device is easy to operate, convenient to maintain, low in using cost and capable of being widely applied to the production and preparing process of the various rock samples for geotechnical engineering science.

The present invention relates to an application device of a high-pressure jet water cutting technique, which allows maximum improvement of the efficiency of the high-pressure jet water cutting operation and achievement of significant economical benefits in high efficiency. At present, all well-known high-pressure jet water cutting application devices operate in a single-cutting point movement pattern in low efficiency, and can only meet the requirements of some high-end users. In the present invention, an existing mature high-pressure jet water production device and a high-pressure water storage device are combined into a device for concentrated supply of high-pressure water that is further provided with cutting heads capable of operating movably and distributed in an array and corresponding automatic control valves thereof; under the control of a central controller, the operating pattern of each cutting head can be selectively controlled, such that multi-point simultaneous cutting is achieved to form an operating face; besides, mobile operation is allowed such that the operating face can be enlarged continuously.
