Sieve for Building Materials Making Plant

 

  1. Product Description:- This is a mobile equipment for sieving building materials and it consists of an inlet Hooper and a mobile belt conveyer with wheels and vibrating screen. The iron net is mounted on the screen body; the net can be replaced by another suitable screen having holes ranging from 2 mm up to 40 mm. The sieving capacity depends on the mesh and on the granulation of the building material to be sieved. The belt conveyer can be inclined as required by means of a hydraulic system. Transportation on the field can be accomplished by a road truck or by any other Vehicle. The complete equipment is mobile and suitable for all types of terrain and materials.


  1.  Market Potential:- Materials that most require sieving are sand, clay soil, aggregates, recycled building materials, lime, etc. With the rapid expansion of the construction industry, the demand for building materials which need sieving is also expanding. This, in turn, has increased the demand for sieving services. It is known that sieving of building materials improves the quality of the building. By the nature of the service it performs, sieving equipment is needed in every major construction sites. Considering the member of construction sites in the country (which are probably in the thousands), one can casily imagine the number of sieving equipment needed in the country. In a situation where the estimated demand (quantified or qualitatively described) is more than the capacity of a plant with the minimum economies of scale, the defining production volume is that volume where the plant becomes financially viable. In this case the minimum capacity is 100 pieces per year and there is definitely a demand to absorb this production volume.

 

  1. Source of Row Material:- The main inputs are sheet metal thickness 4 mm and 6 mm, steel tubes, 2.54 cm and 1.9 cm, steel profiles 40x40 mm and 60x60 mm and various construction materials. The metal sheets will be imported and the others will be obtained from domestic sources.
  2. Process and Technology:- Since a mobile sieving equipment consists of three main parts, i.e. a sheet metal hopper, a conveyer and a vibration sieve, production involves the following processes.

a)      Hopper construction:- sheet metal cutting with shears, steel profiles cutting with a crosscut saw, profile and sheet welding.

b)      Conveyer construction- tubes and steel profiles cutting on a crosscut saw, structure welling, belt turning in turning lathes conveyer assembling. (The belt drive, the driving drum and the reducer are supplied along with the technology.)

c)      Vibration sieve construction- sheet metal cutting with shears, steel profile cutting, turning of the axis, of the bearing housing, of the lid and of the belt,

d)      Construction of detachable box with electrical switches, e) Assembling the three main parts, f) Electrical cables assembling, painting and coating, and testing.

Required machinery and equipment include turning lathes, milling machine, cut saw, console cranes, forck-lift truck, manual electric drills, manual electric grinders, autogenous cutting machine, electro welding machine, compressor and painting gun and tools.

 

  1. Estimated Investment:- For a plant which will fabricate and assemble 100 units of mobile sieving equipment, the estimated investment will be

Ÿ         Building/ shade 500 m2 at Br 2000/m2=             100,000

Ÿ         Machinery                                                      1,600,000

Ÿ         Working Capital                                                800,000

  3,400,000

  1. Benefits: Improves the quality of construction works.
