摘要： PURPOSE:To have stable operation by sensing the amount of exhaust grit exhausted from a roller mill and fed back through the outside, controlling so as to make constant the sum of the amount of fed-back exhaust grit and the amount of the new supplied object to be crushed, and thereby avoiding abrupt change in the load and preventing vibrations of the mill. CONSTITUTION:An adjust gauge 6 controls constant-amount supplying machines 2, 12 so as to make constant the sum of the amount of fed-back exhaust grit W2 and the amount of objects to be crushed W1 supplied anew to a roller mill 1 by reference to the pre-specified total supply amount W3 for said roller mill 1. At this time, the adjust gauge 6 determines the ratio of the new supplied amount W1 to the fed-back amount of exhaust grit W2 so that the level L1 of a grit exhaust tank 13 is kept constant. This is because an increase in the new supplied amount following lowering of the level L1 of the tank 13 will increase the share of new crushed objects in the mill 1 only gradually, which should prevent abrupt change in the overall crushing characteristics. This will prevent vibrations of the mill 1 to lead to provision of stable operations.

摘要： PURPOSE:To provide an excellent fire protecting performance by mixing a polymerized monomer with an inorganic material consisting of natural crushed stone and aluminum hydroxide, and by forming and hardening it to form a noncombustible artifical marble. CONSTITUTION:The mean grain diameters of an inorganic material are devided into four grain diameter groups: coarse grains A of 50 to 300mm, intermediate grains B of 2 to 6mm, fine grains C of 0.04 to 0.10mm, and minute grains D of 0.005 to 0.015wt.%. These grain diameter groups are mixed in the mixing ratio of the coarse grains A 50 to 70wt.%, intermediate grains B 20 to 30wt.%, fine grains C 5 to 15wt.%, and minute grains D 1 to 10wt.%. Further, the polymerized monomer with regard to the total weight 100 parts by weight of the inorganic material is mixed as much 0.5 to 10 parts by weight than the target value of 2 to 5 parts by weight. Then, in order to closely compact the filled material after filling it into a form, the vacuum suction of -10 to -30mmHg, vibration of 60 to 120Hz and 0.5 to 2mm amplitude, and pressurization of 10 to 100kgf/cm are applied to the material so as to be formed. Thus, the manufacturing cost can be reduced.

摘要： PURPOSE:To produce the curved decorative plate having prescribed curvature at the point of time when a coating material cures by setting the curvature of the target curved surface by estimating the return quantity that a base material coated with the coating material for decoration shrinks after curing and curing the coating material while restraining a form. CONSTITUTION:The base material 4 coated with the coating material for decoration on the outer peripheral curved surface is first installed into the form consisting of a frame 1, a slide frame 2 sliding therein and hooks 3 respectively installed thereto at the time of production. The target chordal arc spacing of the curved decorative plate is A at this time but the expansion determined by the rigidity of the base material 4, the shrinkage rate on curing of the coating material and the shape retaining force of the cured coating material arises after curing of the coating material for decoration and, therefore, the form is restrained by applying load on the hooks 3 in such a manner as to attain the curvature chordal arc of A plus (x) added with the return quantity (x). The coating material for decoration is cured while the spacing (w) between the opposite end sides of the curved surface direction is held narrow. As a result, the spacing (w) is widened at the point of time when the curved decorative plate is taken out of the form, by which the prescribed spacing A is obtd. for the radius of the curvature chordal arc.
