Construction of gyratory crusher Nigeria
HST Series Hydraulic Cylinder stone mine machinery is a new and efficient crusher researched and designed autonomously on the base of our twenty years' experience in the crushing industry engaged in design, production, sales and service, combining with the development of modern industrial technology, and drawing advanced crusher technology from the United States, Germany and other countries. HST series hydraulic cylinder gyratory crusher collects mechanical, hydraulic, electrical, automation, intelligent control technology into one set, and represents the world's most advanced crushing technology. It has a number of unmatched advantages compared to traditional crushers, high crushing efficiency, low production costs and easy to maintain and adjust, broken products with excellent grain type, and can be widely used in the medium crushing, fine crushing and super fine crushing operations. HST series hydraulic cylinder cone crusher can be widely used in metal and nonmetal ores, cement, sand, metallurgy and other industries, suitable for the crushing various minerals and rocks whose Platt's hardness are less than 16, such as iron ore, nonferrous metal ore, granite, limestone , quartzite, sandstone, pebbles, etc.
Stone mine machinery Features
1. Large capacity and high efficiency;
2. Good cubical shape;
3. Easy to control and adjust accurately;
4. Stable operation and easy maintenance:
a. HST series Hydraulic Cylinder gyratory crusher adopts the structure of combining spindles floating and hydraulic lifting control system together, and takes discharge port adjustment and overload protect functions into one set , so that to ensure performance while simplifying the structure of the crusher. Compared to other types of cone crusher, it does not have to add complicated discharge opening adjusting device and overload protect system, so that its structure is more simple, and more reliable;
b. Uses positive pressure dustproof system to prevent dust from polluting oil, damaging bearings, thus to extend the life time of oil and equipment;
c. The hydraulic system is designed by high pressure to meet the needs of ordinary pressure, the equipment has higher margin pressure during normal operation, improving the reliability of the hydraulic system;
d. The transmission system uses spiral bevel gear, which is reliable, stable, low noise, and long life.
e. All maintenances are operated from the upper part, facilitating inspection and maintenance;
f. Flexible to replace eccentric and adjust the eccentric distance, to meet different requirements of crushing;
g. Each type of cavity has a different size, which is easy to replace and suitable to different requirements for nesting;
h. Simple operation, to minimize the complexity of the work, and can control in long-distance.
1. The principles and purpose of construction waste crusher
The use of force to overcome the cohesion between the particles of solid waste leaving split into small chunks of solid waste in the process .
The solid waste into a form suitable for further processing or can be processed economically shape and size .
2. The main methods of construction waste crushers are?
a. Solid waste according to the force used when broken , can be broken into mechanical energy and non- mechanical energy crusher crushing two kinds.
b. Mechanical energy broken: the fracturing tool and external force is applied to construction waste, crushed , usually including extrusion, impact, shear and friction , tearing , etc. .
c. Non- mechanical energy fragmentation : the use of electricity, heat and other non- mechanical way of solid waste can be broken, such as low temperature crushing, crushing heat , vacuum broken by sonication and so on.
Crushing equipment used for actual production are usually apply two or more of integrated crushing method in crushing of construction wastes, so better to achieve the good crushing effect .
3. Several types of construction waste crusher are?
① Shearing crusher : the fixed blade and the movable blade through the interaction between the solid waste cut or split into a suitable shape and size , suitable for a low silica content of the waste broken loose .
② Hammer crusher : This is a typical impact crusher is the most common industrial crushing equipment. The principle is the use of large motor driven rotor , the rotor hammer articulated above , the hinge axis of rotation, the weight of waste to the projectile after impact crusher impact when the role of the board , as well as the role of the hammer caused by the shearing of waste crushing . Mainly used for crushing medium intensity and less corrosive solid waste , such as mining wastes , hard plastic, scrap metal and other utensils .
③ Jaw crusher : It is a relatively old crushing equipment, mainly by means of the movable jaw periodically close to or away from the fixed jaw , so that the material being squeezed, splitting and bending and broken, has a simple structure , rugged, easy maintenance, working and reliable. Primarily for strength and toughness, corrosion of the waste .
④ Roll crusher : the use of the rotation of the roller , the roller will be made between the waste involved in crushing squeeze . Roll crusher is widely used in small and medium sized industrial and mining enterprises , the advantage of simple structure , reliable operation , low cost, downside is that productivity is relatively low , broken product particle size is not uniform , crushing ratio is not. Roll crusher is suitable for crushing brittle and ductile of the hard , soft, sticky wet materials , but not broken chunks or hard materials.
