According to the construction design requirement, the powder content of artificial sandstone of sand making machine should be 12-18%. Normally, taking dry method screening, mixing cavity production, mixed production and powder recycle method to control powder content.
Ordinary belt conveyor comprises of belt, carrier roller, frame body, driving device, tension device, bend roller, brake device and cleaning device.
Impact crusher (sand making machine) is working in the serious condition for a long time, which quickens the rotor bearing abrasion. Rotor is irreplaceable in crusher work, and also easy to be damaged. How to take effective measures to improve the service life of impact crusher rotor bearing?
The main factors of affecting the hammer head abrasion of hammer crusher are: hammer head material, manufacturing quality, structure design, crusher technical parameter, feeding situation and the clearance among each part.
Lubrication is the main purpose of establishing liquid friction on the friction surface of mechanical parts, the liquid friction will greatly reduce the mechanical friction, lighten the mechanical wearing, improve the efficiency and extend the service life of machine.
The impact crusher spreads very fast. Until now, it is used for the medium and fine crushing in many industries such as cement, construction material, ore and chemistry etc. It can also be used in primary crushing.
The cone crusher is a commonly used crushing equipment and serves as the primary equipment in mining and construction material production. During the equipment's production process, there will be a variety of situations, how to deal with it?
The screening flow process of vibrating screen is an essential and crucial link in the production of crushing, sand making, and mineral processing. The screening efficiency and producing rate are the main economic index in screening.
Ball mill is an essential grinding equipment in mineral classifying process, which has been widely used to grind the mineral into powder by both dry and wet method.
The stone crusher is an essential crushing equipment in the aggregate crushing production line. The enhancement of crusher productivity is a primary concern for every user in the production process.
