Introduction to Weighing Ingredients System

Weighing ingredients is a kind of ingredients used in the production process of petroleum, metallurgy, chemical, food, building materials, grain and oil, feedstuff, plastic, agriculture and so on, mainly in the way of weight according to the ratio of ingredients, The process is called weighing ingredients.

For example

Such as a dry mortar production enterprises, to be equipped with a formula for insulation mortar as follows:

Cement: 800 kg Coal ash: 250 kg Additive: 50 kg Other 100 kg

analysis:

The proportion of this formula is calculated according to the weight, so the need to use weighing ingredients way.

This time we recommend using a variety of materials (sequential ingredients) in this way.

classification

Classification of weighing ingredients (according to process requirements and principles)

Single material

1. A weighing scale is only equipped with a material, a number of weighing scales to form a variety of physical ingredients system.

2. The measurement of the ingredients at the same time weighing ingredients, ingredients speed.

3. In accordance with the principle of large-scale large-scale small scale material flexible configuration range, ingredients accurate.

Sequential ingredients

1. A number of physical order according to a predetermined order into a metering bucket for the ingredients

2. Ingredient weighing bucket from a batch controller to complete

3. Low production cost and compact structure

Reduce the ingredients

1. For materials with poor mobility, according to the actual exclusion measurement

2. Scale bucket can not be too large, otherwise the accuracy may not be high

3. Can be in the original stock are directly on the transformation

4. When the hopper is filled with material, the controller can open the unloading valve every time. When the material in the hopper reaches the offline, it will start the conveyor structure to the hopper. The material directly to the upper limit is stopped

Weight loss weighing system

1. In the chemical industry, building materials, metallurgy and other industries often have to carry out a variety of continuous batching of materials, so often use the weight scale.Because of the weight scale body is based on bucket scale structure, can directly carry out weight calibration, The instantaneous weight of the test to calculate the actual discharge volume, and then closed-loop adjustment, which can achieve high control accuracy, in general, the cumulative accuracy of 0.2% .Because the bucket structure, calibration, this system maintenance than belt Scales are much easier.

2 .. for a variety of solid, liquid, according to flow control of the occasion. Can be set main materials and accessories, accessories according to the main flow of materials automatically adjust to maintain a constant ratio, in the continuous production of the distance to ensure the progress of the formula, this control method is suitable for trace addition: the addition of activated carbon in the desulfurization system, plastic granulation industry Of the ingredients

Belt scale (spiral scale)

A number of ingredients belt scale (spiral scale) according to the proportion of a certain flow rate uniform feed conveyor belt machine,

Each scale is controlled by a controller, all ingredients scale and host computer to form a network, complete the batching control work.

Computer Batching System

This automatic batching control system is designed using master-slave structure, the weight of the transmitter (T600, WM6800, ZJ8100) and PLC connection, PLC over the weight of the transmitter signal (analog 4-20mA, Communication RS232 / 485) batching programming, PLC and computer software to communicate, the computer can achieve more features. The system can be applied to large concrete batching stations, while the ingredients can be up to 9 to 12 or more.
