Structure of coal ball mill machine

Coal ball mill machine is main equipment used in coal-fired power plant preparation system, also applies to the cement industry, metallurgical industry, chemical industry, sugar industry and other flour milling system, widely used in crushing coal of various hardness. Henan Zhengzhou Mining Machinery Co.,Ltd. to explain the structure of coal steel ball mill, to facilitate everyone on this device have a deeper understanding. Ball mill mainly by the hopper, bearing, transmission, main rotating parts and noise enclosures, motor reducer, rod pin coupling, basic components and other auxiliary components. Rotating barrel is the main part of the ball mill, which is welded by a certain thickness of the cylinder body and two end caps composition. There is a hollow shaft on the end cap, which is supported by a hollow shaft on the main bearing. Both the barrel section and the end cap are lined with wear-resistant steel. The liner of the barrel section is made up of a combination of corrugated linings (also known as linings) and the barrel liner is firmly pressed against the barrel by the transverse pressure created by the fixed wedge and the tightening wedge. Liner form a regular waveform, to enhance the steel ball and fuel, the steel ball regularly and uniform movement and hinder the glide. End liner by the two rows liner of internal and external composition, the outer liner with ribs. In order to allow the liner to expand freely under the impact of heat and the impact of the steel balls and fuel, some clearance is left between the liner. Asbestos sheets are laid between the liner and the large jar, and some are also covered with a soundproof felt, and the outer surface of the large jar is covered with a protective cover. In order to avoid liner bolt hole air leakage and leakage, asbestos rope wrapped around the slot. A maintenance hole is opened on the cylinder body, and the main bearing, large gear wheel, driving cone, motor, reducer and lubrication system support and drive the turning of the large ball mill pot.
