    or the base material mineral is made into concentrate powder through splitting mining, rolling ball milling and air flotation;

    wherein, the tailing powder subjected to the winnowing flotation and tailing recovery processes is respectively returned to the burdening stirring process, and the stones with the particle size larger than 6cm separated in the crushing and screening processes are returned to the rolling ball milling process;

    the base material mineral is actinolite and tremolite;

    the polymer material is organic polymer or inorganic polymer material, or the two are mixed according to the proportion of 1;

    2-4 parts by mass of a composite;

    the rolling ball milling process is to use a rotary drum type ball mill to carry out joint processing of material body rolling and grinding on base material minerals with the grain diameter of 3-25cm, carry out stone powder transmission by using air flow or water flow, and discharge and classify the material body when base material blocks with the grain diameter of 20-25cm in each batch form base material pebbles;

    the tailing recycling process is to completely collect and sieve the tailing powder discharged in the winnowing flotation process into a plurality of mesh grades and then send the mesh grades back to the blending and stirring process to be used as fillers;

    the concrete process engineering of splitting mining, crushing and screening, material mixing and raw material forming, material mixing and thin plate forming, saw cutting and grinding is as follows;

    splitting exploitation;

    vertically drilling a plurality of deep holes which are 60-120cm deep and are arranged along a straight line on a tremolite body by using a rock drill, and then simultaneously performing hydraulic splitting by using 2-5 combined equipment of a hydraulic station and 5 splitters;

    crushing and screening;

    carrying out primary crushing on the base material with the particle size of more than 25cm after the splitting mining procedure by using a large jaw crusher, and then carrying out stone processing on the crushed stone with the particle size of less than 5cm by using a subsequent small crusher and screening equipment with 2-100 meshes, wherein the fixed jaw plate or the movable jaw plate of the large crusher is specially modified into a right-angle steel tooth with the tooth pitch of 25cm, and the stone with the particle size of more than 6cm is sent to a round-rolling ball-milling procedure;

    rolling and ball milling;

    the method is characterized in that conventionally used steel balls are completely eliminated, base material minerals with the grain diameter of 3-25cm are added into a rotary drum type ball mill, base material blocks with the grain diameter of 3-10cm are supplemented in the middle stage of the spheronization processing, water flow is used for carrying and conveying formed fine powder, pebbles with different grain diameters are completely discharged when the base material blocks with the grain diameter of 20-25cm are close to the form of pebbles, then a second batch of base material blocks are added for carrying out the comprehensive processing of pebble spheronization and stone powder, wherein the mass parts of fine powder and pebbles are 1;

    (1-3);

    winnowing flotation;

    the 600-1250-mesh fine mineral is obtained by using a single-groove flotation machine and a chemical auxiliary agent through rough concentration and sweeping processes;

    and (3) tailings recovery;

    calcite and tremolite with the mass of 25-40% separated section by section in the flotation are dried and then screened, and then are divided into 2-3 granularity grades with 400-1250 meshes and then are returned to the burdening and stirring procedure;

    material mixing and raw material forming;

    the method is characterized in that a zigzag linkage type gravel polymerization forming device of Chinese patent 2013100963870 is used for carrying out pebble waste material forming, pebbles with the grain size of 5-25cm are adopted as base materials in the material mixing and stirring, sand grains made of 20-80 meshes of base materials, 200-1250 meshes of tailing powder and unsaturated polyester resin liquid are adopted according to the weight ratio of 82;
