yaccurately to a length from shoulder to shoulder,and also in diameter. The turned staffs andpivots are then hardened, and after hardening,are ground and finished on the wig-wag ma-chine. The form of upright drill which is mostlycalled into use in the manufacture of the severalparts of watches and clocks is that shown in Fig.3. The spring action of the drill stock makes itspecially serviceable for this fine work, and in the drilling of plates, bridges, etc. Fig. 4shows a screw-cutting machine of the Gesswein Co.s make, largely used in watch manu-facture. A wire is fed forward through the chuck, which projects between two movable cut-ting heads, and the tail stock has a horizontal screwed rod which acts as an adjustable stopfor the end of the wire, in determining the length of screw to be cut. One of the slide restsor heads carries the thread-cutting tool, and the other, the cutting-off tool. This figurealso shows a detached view of a tail stock for the same machine, with multiple stop

The attachment is manufactured by the same kind ofmachinery and in the same manner as stem-winding watches, and when properly fitted, thewatch is to all external appearances, and to all intents and purposes, the same as if madeoriginally as a stem-winder. Fig. 5 shows the attachment itself, and Fig. 6 presents it combined with a Waltham movement. The pendant of the watch is usually removed, and one suitable for the new winding stem and crown substituted. The stem projects with-in the case, and carries on its end a small beveled winding pinion, which meshes with a crown wheel pivoted between two plates, one called the main plate and the other the yoke ; the upper or yoke plate is of an elongated shape, and mounted so that it may be rocked upon a pivot. On either side of the central screw or pivot the yoke carries pinions or gear wheels, both meshing with the crown wheel, one (called the inter-mediate winding w

In line with marble dust powder production, the units consists of grinding China mill, powder classifying machine, cyclone collector, retarder, blower, hammer mill and elevator, power and control cabinet. Crushing plant is widely used marble to produce ground calcium carbonate (marble dust, marble dust in sizes from 20 to 200 mesh or gravel) as filler in concrete and paving materials.Hongxing Machinery marble dust powder production plant is widely used in Iran marble processing plant powder.
The mill is the best choice for customers to produce powder of different sizes from 2mm - 5 microns. Line gypsum powder processing making use of advanced processing equipment such as ball type mill, grinder, etc. The grinding China machine gypsum has the advantages of compact size, simple structure, high productivity, low power consumption, stable physical performance, ease of use and low operating cost. Today, our production of gypsum powder is well received in the United States, Canada, France, Germany, England, Spain, Iran, Pakistan, Thailand, Australia, Thailand, Uzbekistan, Colombia, Mexico, etc. Hongxing Machinery can produce gypsum powder production line with an output ranging from 0.3 to 100 TPH TPH. China mainly uses talcum powder dry machining China process, the equipment used to Raymond, mechanical impact mill, jet mill types of main plant and other plants use less. The basic technology used in Hongxing Machinery German production plant spray is widely used. Hongxing Machinery has now proven technology and its ability to produce talc-45μm 5 microns or finer.
The activation technology, change and granulation is gradually promoting the use of nano-talc products have been developed in the common institutions of higher education with Hongxing Machinery. In production line of talcum powder, talc ground is ground to a powder with 200 mesh and 325 mesh, used for papermaking. Talcum powder fine is less than 5 microns, and mainly used in coatings, paints, pharmaceuticals, cosmetics, plastics and other industries. Mill is the major powder making machine to produce calcium carbonate from marble rocks. Hongxing Machinery is a professional manufacturer of grinding China mill and exporter, we can design and manufacture ball type mill, Raymond mill, trapezium mill, trapezium mill European type, coarse powder mill, super thin grinding China mill and so on. Ball mill has many types. Accordin to the working type, it is decided into wet ball mill and dry ball mill.
Energy-saving ball mill has made a great improvement in the structure compared to the traditional ones. Its cylinder and supporting fame compose an integral system, thus, when it is being fixed, Energy-saving ball mill will be hung on the foundation once. Equipped with double-tiered centripetal roller bearing, its power consumption will be reduced by 30%. The intrinsic grill pattern forcing discharge is replaced by overall pattern controlling discharge, which enhances the fineness of final product, and meanwhile increase the capacity by 15-20%.
Ball mill another application is used as cement grinder. Cement China manufacturing mill is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores .Cement mill is not only suitable for over-flow grinding China, but also applicable for cyclic close-flow grinding China together with powder collector.
