产品介绍

主要用于冶金、煤炭、化工、建材等大中型露天矿爆破采场中向无水炮孔装填铵油炸药之用。 

工作前先在地面站装入柴油和多孔粒状硝酸铵。

装药车驶到作业现场,启动取力器,将输料螺旋对准炮孔,在计数器上输入炮孔的装药量,按下启动电钮,多孔粒状硝酸经箱底螺旋送到斜螺旋,再由斜螺旋提到侧螺旋搅拌器内,这时柴油泵也按比例将柴油泵入侧螺旋搅拌器内进行混合,混合均匀的炸药再由侧螺旋输送到炮孔内。当这一炮孔炸药量达到预定量时,控制装置发出命令停机,移位到下一个炮孔开始装药。 

输药效率先为200kg/min——450kg/min; 

计量误差≤2% 

目前4T、6T、8T、15T、25T等六个规格可供选择。

Mainly used for ammonium nitrate fuel oil mixture (ANFO) filling to no water blast hole for large/medium size open-pit blasting stopes, such as metallurgy, coal, chemicals, and building materials etc.

Before the operation, fill in diesel oil and porous granular ammonium nitrate in ground

station.

When explosive loading truck comes to job site, start PTO, get conveying screw and blast hole in focus input the charge of blast hole on counter, and press start button. 

Porous particulate nitrate is delivered to skewed helix through the screw on tank base, lifted in side helical stirrer by skewed helix. At this time, diesel oil is pumped into side helical stirrer to be mixed. The mixed detonator is transterred to blast hole by side helical stirrer. When the explosive charge of this blast hole reaches target volume, the control unit wil order to halt, followed by the next hole for charging.

Charging effectiveness 200kg/min——450kg/min at first;

Measurement error≤2%

Currently, 6 specifications such as 4T, 6T, 8T, 15T and 25T etc are alternative.
