Sandblasting nozzle classification and use

Using high-pressure air as a power source to drive abrasive particles to hit objects within a certain range will produce a great impact. The function of the sandblasting nozzle is to spray abrasive particles on the object evenly and efficiently.

Sandblasting nozzles can be divided into: straight hole sandblasting nozzle, Venturi sandblasting nozzle, double Venturi sandblasting nozzle, angle sandblasting nozzle

Straight hole nozzle: There are only contraction section and straight section inside, the structure is simple and easy to manufacture. This kind of nozzle cannot overcome the vortex phenomenon existing at the inlet end, and the pressure loss is large; the abrasive velocity at the outlet is less than 100m/s under the pressure of 0.7MPa.

Maintenance and storage method of vibrating screen motor and common troubleshooting

The service life of the vibration motor determines the operating life of the entire screen. Therefore, in the normal production, we must always pay attention to whether the working state of the vibrating screen equipment is normal, whether the vibrating motor is in good working condition, timely check and solve some small abnormalities and faults, and do a good job of cleaning and maintenance, because this can greatly increase the vibration screening. Machine and vibration motor life. dewatering screens supplier Maintenance storage precautions during vibrating screen motor operation The equipment can not be completely dust-free, but also has a harsh environment and dusty conditions. The vibration motor is airless and heat-cooled. It relies on natural cooling, so it must be specially maintained. The following is the maintenance content. 1. It is necessary to pay attention to whether the vibration is abnormal during the use process; 2. Always check if the bolts used in the m

300t per hr chalcopyrite washing equipment

Chalcopyrite is a copper-iron sulfide mineral. It often contains trace amounts of gold and silver. Crystals are relatively rare and are tetrahedral-shaped, mostly irregular granular and dense massive aggregates, as well as kidney-shaped and grape-shaped aggregates. Copper yellow, often dark yellow or mottled. The streaks are black with a greenish tint. Chalcopyrite is a relatively common copper mineral, which can be formed in different environments, but it is mainly the product of hydrothermal action and contact metasomatism, and it can often form deposits of a certain scale. The origin is all over the world. In industry, it is the main raw material for copper smelting. In the field of gemology, it is rarely used alone, occasionally as a substitute for pyrite. In addition, it often participates in the composition of some colored stones, inkstones and jade. The high-efficiency spiral chalcopyrite washing machine is mainly used in the washing, grading, impurity removal, and the washing o
