Chemical Industry


The Chemical Industry can be hazardous.  PER-FIL® designs and manufactures auger fillers for the Chemical Industry that take safety and regulation into consideration.  Dust-free filling protects workers from exposure to harmful products.  We offer a wide range of auger filler solutions that can handle inert and caustic products.  Flammable products require Explosion Proof Controls & Wiring.  XP construction available for Class I, Div II; Class II, Div II; or ATEX environments.  Fillers available with 304 and 316 stainless steel, or Armoloy coated contact parts, for caustic and abrasive products.


Case Study
Small neck opening, large fill size

Objective
To fill chemicals into fire extinguishers at high production rates and high accuracy.

Problem
Customer’s small neck opening and large fill size created a challenge when trying to fill fire extinguishers.  Customer’s existing vacuum fillers were inaccurate and required weekly replacement parts (filters) and down time.

Solution
A PER-FIL® packaging line – MF-1 auger filler consisting of two Vacuum Fillers for bulk filling of fire extinguishers and auger fillers to top off to meet desired fill weights. Load cells positioned at each fill station ensure that the NET product weight in each fire extinguisher is exact. The custom designed vacuum filler eliminated design flaws from customer’s previous equipment to minimize downtime and customer only replaces filters every 6 months!


Case Study
Filling wood dough

Objective
To fill wood dough and glazing compound into 1/2 pint, pint, quart and gallon containers.

Problem
Glazing Compound is extremely viscous (1,500,000 cps) and flammable. Multiple container sizes required changeover of filler, lid dropper and closer in less than 2 hours.

Solution
PER-FIL® supplied our Model PF-23H Single Head automatic Inline Auger Filler utilizing Hydraulic Drive Motor.  The equipment was manufactured to meet Class 1, Division 1 explosion proof specifications and featured “submarine” gauges on the control box.  Hand knobs and hand wheels were used to speed up product changeovers.


Case Study
Filling ceramic powder

Objective
FILL-BY-WEIGHT 5 and 10 kg of fine ceramic powder and heat seal into preformed plastic bags.

Problem
Highly abrasive ceramic powder presents excessive equipment wear and occupational dust exposure to operators.

Solution
Design and build an automatic filling and sealing bag line with an enclosed “FILL-BY-WEIGHT” dispensing head. The Built-In dust extraction removed dust from contaminating the work area and seal surfaces of the plastic bags. See the full line of PER-FIL Weigh Fillers.


Case Study
Turnkey Filling Packline

Objective
To supply a turnkey packline to fill plastic containers with wood flour and liquid for radiator stop leak product.

Problem
Production rates of 120 cpm on a 10 gram fill size of wood flour through a container neck opening of 1″ ID.

Solution
Working with the Inline Filling Systems and Hapman Conveyors, PER-FIL® supplied two dual spindle auger fillers to fill four bottles at a time. Ensuring accurate, dust free filling of wood flour at rates in excess of 120 containers per minute.


Case Study
Toxic and expensive product

Objective
To fill 50 lbs of Potassium Gold Cyanide into bag-in-a-box.

Problem
Product is extremely expensive (Gold) and extremely toxic (Cyanide!).  Customer required filling system with fill accuracy +/- 0.25% or better and a dust free fill.  Equipment also needed to meet Class II, Div II, Group F&G requirements.

Solution
PER-FIL® Model MF-1HCW Servo Driven High Capacity Weigh Filler utilizes a Mettler-Toledo Weigh Cell to ensure precise filling.  A pneumatic actuated product shut-off mechanism on the tooling ensures no drip after the dispense.  A pneumatic actuated lift mechanism raises the box during the fill cycle so that the entire top of the box is enclosed by a dust shroud, which is connected to a customer supplied dust collection system.
