Patent No: 2008201591827

1.it is more advanced，more safe for YOVON brand chemical powder filling machine

it can contral the running speed and keep back the running attrition maximum. It is also more safe and energy saving.

2.it is more economical for YOVON brand chemical powder filling machine

It is output: 1500-1800cake/h for common firecrackers. The production cost is 0.03-0.04yuan/cake by machine lower than 0.1yuan by hands. so it will be disinvestment within 3months.because the machine is with more high quality and more energy saving, it is not only lower the waster rate, but also  lower the production cost. so it can improve the produce competitive power.

3.the scientific design and reasonable structure for YOVON brand chemical powder filling machine.  

The total machine length is 12M, the width is no more than 6M.there are 5parts:

a. the institution of auto filling crackers and filling mud(or chaff)

b. the institution of auto feeding empty cracker and mixing chemical powder.

c. the institution of auto filling the chemical powder

d. the institution of auto collecting the mud(or chaff)

e. the institution of collecting and filtering the chemical powder.

f. 1 set of PLC contral system

g. 2pcs patossium perchlorate mixing machine

the mixture ratio is:

patossium perchlorated and perlite powder:1:0.2

sulfur and aluminium powder: 1:1

then you can feed the difference cases.

It require the workshop with 18-20M length, 7-8M width. It require 3workers to complete the total operation.(1 worker for feeding the empty cracers,1 worker for callbacking the filled crackers, and 1 worker for feeding chemical powder in the cases and keeping watch contralor
