How much fineness does the power plant desulfurize limestone powder?

Slag is mainly composed of calcium oxide, silicon dioxide and aluminum oxide mineral composition, slag cement in many aspects better performance than the ordinary Portland cement, and can be preferably applied in water engineering, Lane sea and underground engineering. Preparation of slag crushed concrete The concrete prepared from slag gravel as aggregate has mechanical properties similar to ordinary concrete, and the heat preservation, heat insulation, impermeability, heat resistance and durability are better than ordinary concrete. Therefore, slag has great social and economic value and has important exploration value.

Vertical mill is the preferred equipment for slag to achieve value processing

Dawn Heavy Industry Technology LM Vertical Roller Mill is a high-efficiency and energy-saving mill equipment that combines mature vertical grinding technology, foreign successful experience and our company's technological innovation and upgrade.

Bearing rings: Dimension tolerance, geometric tolerances, and surface quality of bearing` s working surface will influent the operating noise. Naimei Bearing adopts precision CNC machining to dimension precision,  geometric tolerances, design drawing, mold making, grinding, cleaning,  assembly, testing, every link of strict checks, so as to ensure all our products are tested by our strict criteria.

Balls:  The balls evenly with by the cage, often make rolling movement between 2 rings. The shape, size and number will directly influent bearing`s load tolerance and operating capability. We use high precision, small vibration steel ball. It`s surface must be strengthened, no bumps scratches, lacerations, pitting and notch.

Cage: Enclose and move with all or part of the balls. It also be used to insulate the balls, guide the balls` movement and to improve lubrication performance inside the bearing., etc. Naimei Bearing`s cage is commonly made of cold rolling carbon steel. But in the corrosiveness environment, nonparallel or high-speed situation, stainless steel, engineering plastics cagecan be decided on request.

Seal: Naimei Bearing adopts different kind of seal material to meet the requirement of their operating in high temperature and being compatible with grease. Acrylonitrile-butadiene rubber is our standard material. but in high temperature environment ,often adopt fluorocarbons, silicone , PTFE shield.
