Ball mill is the material being broken, and then to smash the key equipment.It is widely used in cement, Portland products, new building material, refractory material, fertilizer, 52555 black and non-ferrous metal ore dressing and glass ceramics production industry, of all kinds of ores and other materials may be grinding of dry or wet grinding.Ball mill is suitable for all kinds of ores and other materials, is widely used in mineral dressing, building materials and chemical and other industries, can be divided into dry type and wet type two kinds of grinding way.According to the row of ore in different ways, can be divided into grid type and overflow type two kinds. Cone crusher to use technology to serve the society, not every entrepreneur can do production, entrepreneurs need to production capability of independent innovation, with good product quality, performance, quality, real service for people.However, in the domestic with independent innovation of cone crusher production of entrepreneurs is not much, most entrepreneurs are still stay in imitation stage, not good use technology to change yourself.Great Wall heavy industry is one of the few production enterprises with independent innovation ability, especially on the cone crusher, not only has the ability of independent research and development, design, manufacturing, also has rich experience in market and practical, with international advanced technology, the cone crusher have made in the industry praise and favored by foreign customers.With the constant development of advanced technology at the same time, the Great Wall heavy industry cone crusher to keep pace with The Times, build a new machinery and equipment for the customer. Silver plate on the left bank power station Dong Gu ditch artificial ballast system design production capacity of 1450 t/h, actually most of the time everyday just 950 t/h production capacity can meet the requirements.System configuration a coarse crushing workshop NP1620 counterattack crusher, two P500 counterattack crusher, usually just a single NP1620 counterattack crusher boot operation can meet the production requirements, design production capacity of more than equipment processing capacity, after five years of use, because of its simple structure and reliable, low malfunction, convenient maintenance, equipment can still maintain good mechanical properties.Material sources under 1000 mm size requirements, discharging control the particle size of 200 mm below, by adjust the implementation gap between back plate and plate hammer, back plate and plate hammer gap adjustment by the hydraulic adjustment device, adjust the quick and easy, first counterattack plate and plate hammer gap adjustment for 310 mm to 320 mm, the secondary counterattack plate and plate hammer gap adjustment for 150 mm to 180 mm, effective control of discharging granularity, grain shape good, broken along the joint surface, produce most of the aggregate shape is a cube, but which produce 5 mm needle flake particle content is higher in the fine aggregate is around 12%, the analysis found the yard to the small material blocks through the rods gap directly into the crusher in the hopper feeder, without crushing, cannot reflect the crusher performance.Emit a lot of dust in the process of crushing, uncontrolled affect environmental protection and health, the crusher frame beam before installation, the upper frame beams in the crushing cavity opened multiple openings, in a place for a water pipe joint on the side of the frame for sprinkler, feeding device and crushing cavity in the right amount water obviously reduced the dust, equipped with sprinkler through production experiment broken after an aggregate quality had no obvious change of the service life of the plate hammer and counterattack plate are basically the same. Crusher is used widely, has a wide applicable scope of material hardness, such as all kinds of granite, basalt, limestone, concrete, asphalt, etc., and so on many occasions we can all see counterattack crusher work condition.For water and electricity construction, bridge building, high-speed road, wharf, airport construction, and other fields have a wide range of applications.
