5-30t/h Dry Mortar Production Line

A plant for the production of dry building mixtures (CCM) can differ significantly from one another in terms of capacity, technical skills, equipment composition and degree of automation. Plants are designed according to the specific technical requirements of each customer.

The plant includes:
- Equipment for sand preparation (drying and classification);
- Equipment for dosing components of the mixture
- Equipment for mixing and packing;
- Control system.
- Equipment for feeding the mixture components;
- Optional equipment

Product Details

 

Sand preparation equipment

To obtain high quality mixtures, all the initial components of the mixture must be dry. The moisture content of the sand should be not higher than 0.5%. For sand drying, three-circuit drum dryer or single tank rotary dryer are used. After drying, Feeding dry sand on vibrating screens with 1, 2 or 3 sieve frames (usually with a mesh size of 0.63, 1.2 and 2.0mm respectively) for classification . After classification, sand will be conveyed in bunkers for cooling to the required temperature, then each size will be fed to the dosing unit and mixer.

Mixture metering equipment

In order to improve the production efficiency of the equipment, improve the accuracy of the batching part and reduce maintenance personnel, the mixing and feeding are also equipped with an automatic batching system. Therefore, the mixture according to the predetermined program will be automatically added to the metering hopper in sequence. In order to ensure the highest productivity, the mixing machine has the least loss of loading and unloading time (each cycle does not exceed 1 minute), and all three main technical operations (metering, mixing and filling the final mixture) are performed simultaneously.

Mixing and filling equipment

Depending on the required capacity, the installation can be completed with one or more filling machines of various types (screw, pneumatic and others). The mixture is packed into valve bags by weight with a metering error of no more than 1%.

Control system

The automatic control system of the production line has a three-level system.

 

low class

Each device has its own control cabinet. The system includes a control unit for quantitative ingredients and mixtures, an algorithm for monitoring the status of the equipment and an operation execution unit, including a consumable monitoring unit and an alarm signal sensor.
 

medium level

The system uses a programmable controller to control each unit according to the requirements of the production process.
 

Top level

The computer provides centralized remote control, formula and parameter input, storage and editing, with warning and alarm signal output, production process parameter visualization, parameter recording and archiving, consumable consumption and finished product output records, etc.

The control system is designed according to customer requirements.

 

Equipment for feeding mixture components

Feeding the main components of the mixture into the feeder can be done in several ways: screw conveyor, bucket elevator, belt conveyor, winch and pneumatic pump. The operation of adding trace additives to the mixer can be completed manually, mechanically or automatically according to customer requirements.

Optional equipment

For normal operation of the plant for the production of dry mixes, it is necessary:
1. Dust collector ---- Install a centralized aspiration system, connect it to dispensers and dispensers.
2. Compressor --- Provide a supply of compressed air with a pressure of at least 0.6 MPa with a flow rate of 600 l / min.

At the work site, the customer himself prepares:
1. To supply sand to the feeder hopper, use a front loader with a bucket lifting height of at least 2.5 m and a bucket volume of 0.4 ... 0.8 m3.
2. Use an electric forklift to move pallets with products and FIBCs.
3. Power supply
