NFLG’s stairs type dry mortar mixing plant is short and takes far lots of land in comparison with tower type one. Its foundation bears less loading and it’s suitable to produce common mortars as well as special ones that are not sensitive to cross mixing of aggregate. In terms of energy consumption, it costs more than tower type one. 

1. Brief introduction
NFLG’s stairs type dry mortar mixing plant is short and takes far lots of land in comparison with tower type one. Its foundation bears less loading and it’s   suitable to produce common mortars as well as special ones that are not sensitive to cross mixing of aggregate. In terms of energy consumption, it costs more than tower type one.

2. Characteristics:
1、Outstanding mixing performance
① The plant is equipped with patented plow-type mixer, which is capable to produce highly homogeneous mixture and discharge finished product completely without any residue. The plant could carry out dosage accurately and perform task highly efficiently.
② Drum body of the mixer is made of high quality wear-resistant super alloy. Mixing blades are made of specific wear-resistant alloy, easy to replace and spacing between them and the drum body is even.
③ Big angle inclined discharge gate is fitted with multiple layers of sealing protection. It’s mechanically self-locked during operation, ensuring absence of material leakage.
④ Big angle discharge gate ensures complete discharge, moreover the mixer is fitted with self-cleaning system, preventing material from sticking or blocking the gate.

2、Accurate, stabile and reliable dosage system:
① Split dosage scale, more stabile dosage!
② Double valve lock structure, preventing overweight  or underweight!
③ Target feeding system, more accurate dosage!
④ Highly precise sensors from internationally renowned suppliers, accurate and reliable measurement!

3、Sand probability screen, accurate, enduring and stabile
① Maintenance hole made of glass steel, quick plugs and dumper spring tension structure, all of them make sure that the screen function freely and efficiently;
② Internationally renowned vibrating motor, reliable and effective;
③ Sieve self-cleaning system-preventing material from blocking;
④ Wide area of stainless steel sieve, quick access to observation hole, easy and convenient to operate.

4、Targeted environment friendly equipment
① Drying and cooling procedures are accompanied by container-type gravity dust collector and bag pulse dust collector to minimize dust emission. It’s fitted with high quality thermally resistant bags and skeleton device, which not only prolong bags’ service life, but also effectively collects dust generated during production, meeting international and local environment protection requirements;
② For additive an individual pulse dust collector is applied to prevent additive from leaking and thus imposing danger to personnel as well as meet environment protection requirements;
③ Silos are fitted with specific pulse dust collector atop to prevent overpressure explosion;
④ Points that may generate dust are fitted with pulse dust collectors and reclaimed dust is reused.

5、Efficient, energy saving and reliable drying system
NFLG implemented domestically pioneer double-circuit drying and cooling drum in its plants.
① Applying hard-surface reducer of renowned brands;
② Applying split bolt fastening structure, making it easy to dissemble and maintain;
③ Output material temperature≤65℃，water content＜0.5%，which are designed to prevent damage to additive activity due to too high temperature of sand that may compromise quality of finished product;
④ Rim made of forged steel and drum shell made of boiler steel plate ensure service life and reliable work of the drying drum;
⑤ Wide selection of burners that use coal, gas or biological fuel are available for customers.

6、Finished product solutions that meets various requirements
① Bulk loading system offered by NFLG could effortlessly solve environment protection problem at worksite. Its unique structure could effectively prevent finished product from segregation during loading;
② Air valve packaging machine, vane packaging machine and ton-bag packaging machine are available for choice to meet different dry mortar requirements in terms of package;
③ NFLG obtains rich experience in field of designing integrated automatic packaging, stacking and loading production line, which could satisfy customers involved in huge volume special mortar production;

7、Reliable, stabile and user-friendly double-computer synchronized control system
   The dry mortar mixing plants and FB series dry mortar mixing plants offered by NFLG are controlled and operated via double synchronized computer system. Its hardware mainly consists of two computers, high-performance PLC, human-machine interface, high precision dosage units and low-voltage electric components from internationally renowned brands. They work in concert with software developed by NFLG itself to realize smooth and reliable control of production process. Under the synchronized control system, any of the two computers could independently carry out control of the production process. When one of them malfunctions or faults the other one immediately takes charge over without any manual interruption to ensure that production continues as before.
