Line production of dry building mixtures SB-240V capacity 10 t/h

Installation for the production of dry building mixtures (next setting) with capacity up to 10 t/h is designed for preparation of dry mortars based on cement and gypsum binders using various mineral additives, stabilizing quality and giving the special properties of the mixture.

The operation of the installation is indoors at a temperature ambient air from plus 5 to plus 40 degrees Celsius.

Installations for the production of dry building mixtures are developed in individual option under the Customer's premises. For this the location of the upcoming installation at first sent a constructor that produces all the necessary measurements and together with the Customer prepares the technical design assignment. Next 20÷30 days, the plant develops a rough draft, negotiate with The customer and after that directs technical and commercial proposal on supply installation, which serves as a basis for the preparation of the contract. After signing of the contract by the parties, the Customer makes an advance payment in the amount of 40-50% of the total cost of the equipment. Average time the manufacture of this equipment is 120 ÷ 150 days with regard to development of working project.

Below is an example of a typical project installation of dry building mixtures SB-240-V, manufactured by PJSC "buttonmash" in 2012.

The structure and operation of the installation

Cooking technology products at the facility mainly depends from careful preparation of dry, fractionated sand different the particle size. Therefore, the main part of the process of production of dry mixes is working with sand. The installation starts with downloading raw (wet) sand in a hopper grab crane or front end loader. The initial moisture content of the sand should not exceed 4%. To improve the expiry of the sand in the hopper wall set the vibrator. Regulation of the thickness of the sand layer on the tape feeder is the valve that is installed at the bottom of the hopper. Raw sand by means of a feeder is served in the Elevator No. 1, which delivers it in vibrating screen primary treatment. Using vibrating screens are the primary processing of raw sand, during which eliminated a large litter fraction of more than 10 mm, Then the sand gets into the dryer drum, which is drying. Clothes dryer is a rotating cylinder with blades located throughout the inner surface and a gas burner, gas-fired and having the necessary control equipment. Tumble dried sand to a moisture content of 0.2-0.4%. Clothes dryer works on the principle of backflow - meeting material moving stream of hot air. Having clothes dryer, hot sand falls through the Elevator No. 2 in hopper dry sand, where it is cooled and stored until requested. Next, the cooled sand by means of a feeder belt and Elevator No. 3 gets to 4 fractional vibrating screen. From shakers fraction of sand larger than 3 mm is directed into the waste bunker. Small and medium-sized fraction by gravity, and large using the auger comes in 3 compartment feed hopper, and stored until use. Management mechanisms performed by operators with local control panels. Plot download wet sand (vibrator hopper and feeder the sand) is controlled from the local control panel No. 1. Drying sand controlled from the local control panel No. 2 and includes the control of the drying dryer, exhaust fan, elevat
