Four key steps to be concerned in the design of dry powder mortar drying machine

Dry powder mortar drying machine production line design should pay attention to the four main links, a total plane design and construction of a certain size of dry powder mortar drying machine production line, the factory covers an area of not less than 25 acres.
Four key steps to be concerned in the design of dry powder mortar drying machine
First, the total graphic design
Construction of a certain size of dry powder mortar drying machine production line, the factory covers an area of not less than 25 acres. The best site near the origin of raw materials, transportation should be considered a large truck traffic convenience. Mixing tower covers an area of 200 square meters or so in the area of not less than 3000 square meters, warehouse. In addition to supporting life, office facilities, should take full account of cement, finished goods in bulk vehicles working place, set aside the storage space for mobile finished products.
General layout design to follow the general layout of the industrial design, because of the larger amount of sand and gravel, the whole plane layout should consider the smooth flow of the logistics, to consider the vehicle stop, waiting for the required field. Sand preparation, drying workshop should be arranged in the entire plant minimum wind frequency on the direction, as close to the source of heat, power.
Two, process design
(1) aggregate pretreatment process
(2) raw material lifting, storage process
(3) dosing process
(4) mixing process
(5) packaging, bulk process
Three, architecture, structural design
(1) according to GB50016 "building design fire protection code" and so on, the main production line of dry powder mortar drying machine production line is two. Drying workshop fire hazard classification for class D workshop, raw materials, finished products warehouse, admixture fire hazard classification for class E warehouse, mixing and batching tower, machine-made sand workshop fire hazard classification for class E plant.
(2) the production line of dry powder mortar drying machine adopts the tower layout process, and the proportioning and mixing tower adopts steel structure frame, which is usually more than 30m. Steel structure, there are personnel operations, belong to the building, design should be according to the building design, design drawings should be approved by the Construction Department of the construction drawing review body audit.
(structural components of dry powder mortar drying machine production line should be according to the requirements of bearing capacity limit state, respectively to the bearing capacity and stability, fatigue, deformation, crack and crack width calculation and hydrochloric acid, in the earthquake zone structure in accordance with the conditions, there should be are applied to the calculation of bearing capacity of the anti-seismic structural components, silos, ingredients tower construction of buildings, should set the settlement observation point.
Four, environmental protection, occupational health design
(1) the production of dry powder mortar is similar to many processes of cement production, the raw material properties are similar, and the environmental protection requirements of the cement industry enterprises are suitable for the environmental protection design.
(2) dust removal system should be according to the pollution source were designed, sand drying system should be set up independently of the precipitator, aggregate crushing screening should be set, bag type dust collector dust concentration, batching bin, silo roof design of single pulse bag type dust collector is appropriate, mixer, batching scales, meter should adopt the form of reinforcement cage coat dust bag.
(3) the mixing tower as a building, should meet the requirements of lighting and ventilation, design and implementation of industrial enterprise design health standards.
(4) the tower stairs ingredients tilt angle, width and railings should meet the design requirements.
(5) sand drying workshop should consider the ventilation, air compressor room should consider noise reduction, sound absorption design.
