Gear type screening crusher

British MMD Mining Machinery Development Group Co., Ltd. (hereinafter referred to as MMD Mining Machine) is a professional company specializing in the research and development of material crushing technology and equipment. In 1978, it developed the world-class MMD gear type screening crusher . This MMD type screening crusher with high efficiency, compact structure, environmental protection and energy saving can meet the requirements of crushing different rock minerals. It has been widely used in energy, mining and construction industries in more than 90 countries and regions. The technical parameters are shown in the table.
        The characteristics of MMD screening crusher are: 1 new principle: crushing materials by shear force and tension; 2 new design: double action of screening and crushing; 3 new materials: high strength, high wear resistance; 4 new structure: Low height, small size and light weight; 5 can be moved, semi-mobile or fixed installation; 6 low operating cost; 7 short time for crushing station; 8 treatment of dry ore, wet ore, non-blocking.

PVC RESIN SG5

In terms of building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, and fibers, PVC was the world`s largest production of general-purpose plastics, and its applications are very widely. Widely used in all aspects.

PVC is a white powder with an amorphous structure. The degree of branching is relatively small. The relative density is about 1.4. The glass transition temperature is 77~90°C. It begins to decompose at about 170°C. It has poor stability to light and heat. After prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, causing discoloration, and the physical and mechanical properties also rapidly decline. In actual applications, stabilizers must be added to improve the stability of heat and light.

the Degree of polymerization of SG5 is 1000. usually we also call PVC Resin S1000. Its K-value is K67.
