Blasting operations must adhere to the following basic principles:
1. The blasting personnel must pass the assessment, and after obtaining the blasting power, the blasting operation and the processing of the relevant blasting materials can be carried out;
2. After the blasting materials are taken to the working surface, they must be placed in a special gunpowder or gunpowder warehouse for safekeeping;
3. When the number of blastholes on the working surface is more than 5 and simultaneous blasting, the next ignition must be used, and no single ignition is allowed;
4. If an ignition failure occurs due to a working surface water ambassador, an electrical detonation should be used to prevent the occurrence of a rifle or a personal accident;
5. When using electrical blasting, all power sources within the safety regulations must be removed before the charging connection is made to prevent stray currents from being generated;
6. A warning signal must be issued before the shot is fired; immediately after the shot is fired for a period of time, before the warning signal and other work can be removed.

Two-component Proportional Valve



Introduction:
RPV series proportional valves mix regrind and new materials in a proper proportion, and then send them back to the molding machine to achieve a proportional mixing and loading effect. It features directly mounted on loaders or mounted on the pipeline. Besides, it is applicable to Euro loaders and has to equip control box to perform when in other situations.


Features:
"European type" design, classy appearance, easy installation and operation.

Unique design of valve body, make material conveying more smoothly.

The performance of solenoid valve is so stable that the air cylinder acts accurately to ensure a proportional mixing of new and
regrind materials.

Instant recycling the regrind materials to reduce the production cost.

Control box is optionally available when performing in other situations.

Equipped with 1~4 levels working function selection, making material mixing more evenly.
