What are the productions? Now the complete set of lime-sand brick equipment in my country can produce porous bricks, but the porosity is low. From the 1960s to the present, it is still a turntable model with complex structure and large inertia of moving parts, so it is difficult to increase the output. The unburned brick machine is also of the crankshaft type that has been manufactured for 40 years, and the pressing force is small. They are all small machines, and the models are backward. The lime-sand brick production line with an annual output of 30 million standard bricks has invested 6.5 million yuan in equipment. For the porous block production line with the same output, the equipment investment is 1 million yuan. Based on the raw material cost of 800 yuan for 10,000 standard bricks, the raw material cost saved by the porous block is: 3000times; 800 yuan divide; 2 = 1.2 million yuan. (Note: 5% cement is added to the formula, the strength is equivalent, and the cost of cement and the cost of autoclaving are offset). Therefore, there is no need to compare the disparity in quality, the investment in the production line and the raw material cost saved each year are enough to make the existing lime-sand brick production line withdraw from the market.
The complete set of lime sand brick equipment includes: vibrating feeder, jaw crusher (coarse crushing), ring hammer crusher (fine crushing), mixer, digester, lime sand autoclaved brick machine, wheel mill, autoclave and other main equipment, as well as auxiliary equipment such as box feeders, screw conveyors, climbing buckets, aggregate scales, belt conveyors, maintenance trolleys, and ferry cars.
