Liquid Loss in weight feeder

Company Profile

Nanjing Pege Techno Machine Co., Ltd has been working with bulk ingredients feeding, weighing for more than 10 years. We have gained knowledge and have become a reliable feeder supplier for various customers.

Whether for use in the plastics, chemical, pharmaceutical, food, pet food, detergent, ceramics, glass or construction material industries – the customer and his requirements are most important. Before we submit a quotation, we analyze your ingredient and work with you to determine your needs. Continuing this with our 10 years of experience we select the best device from our extensive product line which can feed any conceivable ingredient. All our machines can be further modified to fit the individual needs of our customers.

Besides extensive process advice we have many services such as feeding trials in our test labs, start-ups and operator training on site or at our training center.

We also offer maintenance, customized screws, spare parts and repairs as parts of our comprehensive after-sales services at reasonable prices.

Principle
In loss-in-weight feeding, the entire feeder, hopper and material are continuously weighed. As the feeder discharges material, the rate of decline in system weight is computed, and feeder speed is adjusted to maintain the desired (set) rate.

Applications Material

Liquid Additive DCP Silane Maleic Anhydride

Features

1. Cantilever type weighing frame ensure lower gravity(barycenter) center, weaker

vibration and anti-interference performance of the whole feeder.

1. Stainless Steel bellow sensor has the feature of only slight deformation after long time use, and high precision with less signal drift, and is durable for bad environment use.
2. 485 Digital transmission of weighing data has the feature of no attenuation and anti- interference during the period of data transmission.
3. Hydraulic Diaphragm Pump, Plunger Pump, Gear Pump are selectable.
4. Equipped with complete isolated SUS304 bellow spring damping type spray gun, has the feature of keeping pressure stable within 48 hours.
5. Explosion proof, heat preservation by water or electricity are selectable

FAQs

1. How does loss in weight feeder works?

Gravimetric loss in weight feeder is an instrument that is important to control and measure the speed of a substance in an instrument system. This equipment can handle the bulk solids. It allows the solid to discharge at a constant weight per unit time. The unit of measurement is kg/min or Kg/hour. The signal about the weight is used as a system of feedback control. It controls and monitors the feed rate that enters a instrument. The weighing systems include several examples such as platform scales, load-cells, weigh hoppers, etc. Depending on the overall process, the gravimetric feeder may be a loss-in-weight system or a gain-in-weight system.

1. What are the most important benefits the gravimetric feeder can give to you?

To ensure excellent quality of final product by accurately metering the bulk ingredients.

To reduce the labor cost and improve labor work environment

To Improve product stability

Reduce dust pollution and be more environmentally friendly

1. What is general accuracy rate of the good loss in weight feeder?

Our general feeder’s feeding accuracy rate can be 0.5%. The micro twin screw loss in weight feeder accuracy rate can be up to 0.3%.

1. What is the main composition of a typical loss in weight feeder?

Loss-in weight feeders for bulk materials consist of storage hopper, controlled feeding devices such as augers, screws chutes, pumps as well as scales or load cells, loss-in-weight controllers or rather loss-in-weight feeder controllers. Optional: e.g. agitators to improve the quality of the bulk material.
