NewWeigh Short Linear Weigher
Description
NEWWEIGH SHORT LINEAR WEIGHER
The NewWeigh linear weigher, featuring a single vibrating chute between the hopper and the weighing bin, is particularly suitable for fine-grained products. This short version results in less dust generation and less segregation of products such as tea, muesli and seed mixes. Furthermore, thanks to its compact footprint, it takes up very little space in your production area.

SHORT LINEAR WEIGHING OUTPUT
Depending on the weight and volume, the maximum output is 20 weighings per minute per weighing head. For higher capacities, weighing machines can be configured with up to 4 heads, thereby achieving a capacity of up to 80 portions per minute. In addition, various models of linear weighers are available for weights up to 3 kg (8 litres in volume) and larger models up to 10 kg (30 litres in volume).
OPERATION
The weighing process begins in the weighing machine’s feed hopper, where the product is fed in bulk. The product is then transported to the weighing hopper via a vibrating chute using what is known as coarse and fine dosing. During coarse dosing, the vibrating chute operates at a higher amplitude to convey approximately 80 per cent of the set weight into the weighing hopper as quickly as possible. This is followed by fine dosing, during which the amplitude is lower, thereby achieving optimum accuracy. Once the weight has been reached and verified, the weighing hopper opens automatically and the next weighing cycle begins.
DESIGN AND OPTIONS
NewWeigh’s weighers are constructed entirely from stainless steel; all parts that come into contact with the product are made of 304 stainless steel (2B finish). A version in 316 stainless steel is also available on request. All contact parts can be treated with, for example, Teflon to prevent sticking and product build-up. The exterior of the hopper and the drop chute can also be coated to reduce noise levels. The pneumatic components are from Festo, which are widely available and guarantee consistent, high quality.
Some commonly seen options include:
Dust enclosure
Angle of vibrating chutes for easier product transport
Touchscreen in a separate cabinet for operating the weigher
Transfer hopper to the packaging machine
Platform / mounting frame above the packaging machine
CONTROL SYSTEM
NewWeigh weighers are fitted with a high-quality IPC control system featuring:
User-friendly touch screen control panel in various languages
Storage for 99 programmes, allowing for quick product changes
MID approval, making them suitable for calibration
An FTP server for storing all individual weights, which can be read remotely.
