The invention relates to a full-automatic multi-grinding head independently moving polishing machine, which comprises a controller, a main motor, a cleaning device and a conveyer belt. A grinding head and a stand are fixedly connected with an upright post respectively, the top of the upright post is fixedly connected with an upper beam, and the grinding head is connected with a main shaft of a main shaft box. The polishing machine is characterized in that the main motor drives the main shaft of the main shaft box through a first-level conveyer belt, the main shaft is connected with the grinding head, the main shaft box is respectively connected with an independent left moving mechanism and an independent right moving mechanism as well as a lifting mechanism, and the lifting mechanism comprises a mechanical lifting mechanism and a pneumatic lifting mechanism. The polishing machine has a compact and reasonable structure, a single grinding head can swing solely, and the single grinding head can solely grind an irregular plate with an unfilled corner, so that the polishing machine radically solves a fundamental problem for stabilizing yield and quality. The polishing machine adopts pneumatic and mechanical double-level lifting so as to increase lifting stroke, and is widely applied for machining stones, so that the polishing machine not only can grind the prior stones, but also can grind various boulder strips with different heights and specifications. The polishing machine has the advantages of high working efficiency and long service life.

The invention discloses a preparation method of a novel magnetic clay nanometer composite material. The preparation method is characterized in that carbon sources such as saccharose, clay and nickel nitrate are used as raw materials, nickel nitrate and clay are mixed in a mass ratio of 1: (10-30) at a room temperature and are subjected to ball milling, a solid mixture obtained after high-temperature calcination is mixed with the carbon sources in a mass ratio of 1: (5-20), and ball milling and calcination are carried out again so as to obtain the novel magnetic clay nanometer composite material. According to the magnetic composite material prepared by the method, the low-price clay is used as a raw material and is loaded with a magnetic material and a carbon material. The preparation method has the advantages that the preparation process is simple, and the raw materials are easily available and environmentally friendly and practical production requirements are met. The novel magnetic clay nanometer composite material can be widely applied to the purification of industrial raw materials, the treatment of wastewater and the advanced treatment of nanometer film materials, industrial wastewater and dyestuff. Meanwhile, the composite material also has magnetism and can be rapidly separated and recycled under the effect of an external magnetic film without causing secondary pollution.
