Shanghai Four Tooth Roller Crusher Ensures The Particle SizeLast Update:2020-05-08 04:51:05
Roller crusher is a very old crushing equipment, its structure is simple, mainly used in cement, Portland and other industrial sectors of the ore medium and fine crushing operations. Crusher roll is the main working mechanism of crusher, which is composed of shaft, hub and roll skin. The wear degree of the roller skin has a great influence on the working efficiency of the roller crusher. Only when the roller skin is in a good state, the crusher can obtain a higher production capacity.
Roller crusher is divided into: roller crusher, four roller crusher, toothed roller crusher, which is divided according to specifications! Adjustment of discharge grain size: wedge or gasket adjustment device is installed between two roller wheels, and adjustment bolt is installed at the top of wedge device. When the adjustment bolt pulls up the wedge block, the wedge block pushes the movable roller wheel away from the fixed wheel, that is, the gap between the two roller wheels becomes larger and the discharge grain size becomes larger. When the wedge block is downward, the gap between the two roller wheels becomes smaller and the discharge grain size becomes smaller under the action of compression spring. The gasket device adjusts the size of the discharge particle size by increasing or decreasing the number or thickness of the gasket. When the gasket is increased, the gap between the two rollers becomes larger; when the gasket is reduced, the gap between the two rollers becomes smaller, and the discharge particle size becomes smaller.
The four tooth roller crusher is suitable for medium hardness and soft materials with compressive strength less than 200MPa and humidity less than 30%, and it is required to crush the fine and medium crushing operations with less and more particles. For example, coal, coke, fertilizer raw materials, petroleum coke, glass tube, chemical raw materials and other solid materials, the machine has the characteristics of low maintenance cost, large crushing ratio, reliable performance, less dust, low noise and so on.
1. Bearing bears all loads of the machine, so good lubrication has a great relationship with bearing life, which directly affects the service life and operation rate of the machine. Therefore, the lubricating oil required to be injected needs to be clean and well sealed. The main oil injection place of the machine (1) rotating bearing (2) roller bearing (3) all gears (4) movable bearing and sliding plane.
After long-term technical research and international exchanges, the quality and technical content of Caesar's products have reached the first-class level in the world, and have been widely recognized and praised in the international market; the products are exported to more than 160 countries, such as the United States, Russia, etcGet Price Now
