How to tackle the common issue of rotary sluice of VRM feeding system?

If your VRM feeder is harassed by below issues:
1) high humidity of bulk materials
2) high wear of the rotary sluice
3) frequent stoppage due to stuck or jamming of the rotary sluice
4) high electric power consumption of ID fan system of your VRM
5）high content of O2 in your exhaust air of VRM emission end
6) Unsteady feeding of your VRM operation

It’s worth studying and reading this article!

The below plate feeder is designed to replace original rotary sluice. It is composed of a buffer bin and a sealed plate feeder. The natural stacking of bulk materials in the buffer bin helps prevent any false air admission.

According to the output of the mill and the set values of the buffer bin, a designed computer automatically adjusts the running speed of the plate feeder and adjusts the feeding rate of the blending station.it stop all false air and guarantee smooth and even feeding.

No false air can pass the stacking of bulk materials in the buffer bin. Those bulk materials do not contact the equipment shell, which minimize the wear and damage that usually happened a lot in rotary sluice design.

This plate feeder design totally rip off the traditional design of rotary sluice. Thanks to its superior performance in false air prevention, and steady operation of bulk materials feeding, nowadays more than 300 of such units are applied in Chinese cement plants, for coal mill, raw mill etc.

Generally speaking, the false air prevention cause less electric power consumption in ID fan system. On average, 1.5kwh/MT feeding materials can be achieved through this design. The ROI can be as short as 6 months only because of this power saving advantage!

Exports from South also increased by 52.66 percent to 542,925 tons in May 2021 from 355,654 tons during the same month last year. During the first eleven months of this fiscal year, total cement despatches (domestic and exports) were 52.222 million tons which is 20.91 percent higher than 43.189 million tons of cement despatched during the corresponding period of last fiscal year. During July 20 to May 21, local despatches increased by 20.26 percent to 43.451 million tons from 36.13 million tons in the same period last year. Exports increased from 7.059 million tons during the first 11 months of the last fiscal to 8.771 million tons during July 20 to May 21, showing a growth of 24.25 percent.

Exports from North were 2.365 million tons showing an increase of 22.89 percent over exports of 1.924 million tons during the same period of last fiscal year. Local despatches from South based mills were 6.729 million tons during the first eleven months of the current fiscal year which was 29.73 percent higher than 5.187 million tons despatched during the corresponding period of last fiscal year. The exports from South recorded 6.406 million tons registering an increase of 24.76 percent over exports of 5.135 million tons during the same period last year.

A spokesman of APCMA said that cement industry is among the highest contributors to the national exchequer as its contribution has increased to 143 billion rupees in 2019-20. He said that cement industry is subject to FED of Rs. 1500 per ton and GST of 17% of maximum retail price and these taxes calculate to around Rs. 170 per bag. Besides FED, industry also pays custom duty and taxes on machinery, spare parts imports and on import of coal and pet coke. Coal prices are showing significant upward trend as the C&F cost has increased from around US $ 60 per ton to around US$ 120 per ton during the current financial year. This has increased the cost of doing business as presently coal and pet coke are being used as fuel/raw material for various manufacturing concerns. He appealed to the government to abolish the FED and reduce other duties and taxes in order to provide opportunity to the manufacturers to control their cost of production and further optimize/ expand their Plant that will in turn help generate more employment and revenues for the government.

Bestway Cement to set up greenfield cement plant in Punjab

Bestway Cement Ltd has informed the Pakistan Stock Exchange on 27 May that it is setting up a greenfield cement plant with a clinker capacity of 7200tpd, near Paikhel, Mianwali, Punjab province.

Company Secretary, Sehar Husain, added that the plant would have a 9MW waste heat recovery plant built by Sinoma International Engineering Co Ltd of China.

In addition, all necessary regulatory approvals and financial arrangements have been secured. However, no time frame of completion was disclosed.

Bestway is the second-largest cement producer in the country with a total capacity of 10.7Mta with six state-of-the-art production lines at four locations: Hattar, Farooqia, Chakwal and Kallar Kahar.

Operating highlights
The company recorded a gross turnover of PKR63.2bn (US$407.1m) in the nine months ended 31 March 2021, 30 per cent higher compared with PKR48.8bn during the same period last year.

Net turnover for the period increased by 46 per cent, from PKR28.7bn to PKR41.9bn. This was driven by higher sales volume, a decrease in federal excise duty and improved selling prices. Profit after taxation for the period amounted to PKR8.3bn as compared to a loss of PKR0.02bn for the same period last year. During this period, its total cement dispatches grew by 19 per cent as compared with the same period last year, better than the overall industry growth of 18 per cent.

Pakistan records mixed export and production data

The Federal Bureau of Statistics (FBS) of Pakistan has released cement export and production data for the July 2020-April 2021 (10 months) and July 2020-March 2021 (nine months) periods. It continues to post mixed trends in export and local production.

Export volumes increased during this period, but revenues remained thin in dollar terms, reflecting a weaker price market for cement and clinker. Meanwhile, local output increased driven by high local demands and enabled by capacity expansions.

AHL Research gives credit to the increase in northern mill exports, as they exported good volumes to Afghanistan and the south, as well as to the export of sufficient cargoes to Bangladesh and Sri Lanka.

Export
Pakistan’s cement industry earned US$225.1m of export revenue by delivering 6.624Mt of cement and clinker overseas in 10MFY20-21, compared to US$223.2m from 5.959Mt of exports in the year-ago period. The export data represents a meagre growth of 0.8 per cent on the export front in dollar terms but reflects the double-digit growth of 11.2 per cent in terms of volumes during this period, as reported by FBS.

In local currency terms, the export value increased by four per cent to PKR36.34bn (US$225.056m) from PKR34.96bn during this 10MFY20-21. Nevertheless, the cost per tonne fell from US$37.45/t in 10MFY19-20 to US$33.97/t in the July 2020-April 2021 period.

However, in April 2021 alone revenues contract to US$15.012m on the export of 377,016t from US$26.8492m on the export of 776,934t cement and clinker exports in March 2021, apparently due to COVID-19. The export trend represents a substantial fall of 44.1 per cent and 51.5 per cent in terms of value and quantity, respectively.

However, in the comparison period of April 2020, when exports stood at US$13.13m on the shipments of 366,849t of commodities, exports grew by 14.3 per cent in value and 2.8 per cent in quantity, YoY.

Production in 9MFY21
The Large Scale Manufacturing Industries Index (LSMI) sees a growth trend in July 2020-March 2021 in Pakistan. The latest data released by PBS suggests that LSMI output, including cement, during 09MFY21, witnessed an increase of nine per cent YoY and an increase of 22.4 per cent YoY during March 2021.

During this cumulative nine-month period of July 2020-March 2021, Pakistan’s cement production increased by 25.1 per cent, YoY to 37.62Mt compared to 30.663Mt a year earlier. The upward trend in cement production was also observed in March 2021 alone, when production rose by 57.2 per cent to 4.711Mt versus 2.996Mt in the same month last year.

Dangote Cement Unfolds Measures to Meet Demand, Reduce Price

Dangote Cement Plc yesterday listed steps it’s taking to increase the supply of cement in order to meet the huge demand for the commodity as well as reduce the price of cement.

Dangote Group’s new Chief Commercial Officer, Mr. Rabiu Umar, at a media briefing in Lagos, yesterday, expressed optimism that the price of cement would decrease once Dangote Cement, a dominant player in the sector brings into operation its new line at Obajana, Kogi State, as well as its new line in Okpella, Edo State and the reactivation of its Gboko plant that has been shut down for almost four years.

Apart from increasing its volume of output, the Dangote Cement has also put a hold on its export market in order to ensure that Nigeria has a sufficient supply of cement, he said.
The price of cement in the country has risen sharply from about N2,500 as of the fourth quarter of 2020, to about N4,000 presently. Dangote Cement controls 60 per cent of the market in Nigeria.

Explaining the reason for the surge in cement price, Umar said: “There is a surge in demand immediately after COVID-19 disruption. This surge in demand is not a localised Nigerian phenomenon as a couple of countries around the world like Pakistan and Mexico, among others are seeing a rising incident of demand for cement.

“So the question is what is the Dangote Cement Plc doing to bring it down? First and foremost we have invested in a new line that has been completed in Obajana, which is waiting for the power plant for us to start bringing out more cement.

“We also have a new line in Okpella, Edo State, which is going to start operation very soon. Also we have restarted one of our plants in Gboko, Benue State that has not worked for almost four years all in a bid to make sure that there is enough production to supply the market.”

He added: “What drives price is the interplay of the market forces of demand and supply. As a business, we have not increased our price. And the only way to deal with this upsurge is to have adequate capacity to supply the market by producing more to prevent a break in the supply chain that will lead to arbitrage.

“So, what we are trying to do is to ensure that we increase our supply of cement in the market and we believe that will help to manage the skyrocketing prices of cement.

“We have also stopped exporting cement to ensure that we meet local demand in spite of the fact that the foreign exchange from exports is very valuable in times like this.”
He added that it would be difficult to control ex-factory prices, which are responsible for propelling the prices upward because of the number of intermediaries in the distribution chain.

Dangote Cement, according to him, has 500 distributors and about 57,000 retail outlets in the country that would not be easy to police in order to enforce uniform price regime.

“Nobody can say when the price will drop, which is best left for the forces of demand and supply. All these new capacities we are developing are things we are doing as a responsible business organisation to ensure that we have enough supply that will meet the demand and shift the market to a new equilibrium since pricing is nothing but the willingness to buy and willingness to sell at a price within a given period. But what we are certain of is that demand and supply will always determine the price of any given product at any time,” he added.

Umar stated that the Dangote Cement would be supplying additional 15,000 tonnes of cement per day to help to stabilise the domestic price of the product, in the next 90 days.

“We are making record sales, meaning that we are selling more than we did over the past years. That tells you that there is a surge in demand. So, we are in a sold-out situation in the country. The main test of demand is when you have more capacity to supply the market,” he stated.

Dangote Cement is also injecting 2,000 brand new trucks in order to make sure that the distribution of the increased output of cement to the market is taken care of.
“All these efforts will lead to the creation of 3,000 new direct jobs in the economy,” Umar said.

He added that the group has a system that takes care of proper governance of its distributors.

“We ensure regional equity in our distribution to ensure price stability. Our philosophy is to stay with our customers who have been with us for many years,” he said.

Pakistan, China sign agreement on waste heat recovery power plant’s project

An agreement on a renovation project of a waste heat recovery power plant was signed between China Sinoma Energy Conservation Limited (Sinoma EC) and Lucky Cement, according to a report published by the Gwadar Pro on Wednesday.

Under the agreement, the generating capacity of the two power stations utilising waste heat is expected to increase by about 4MW after the transformation.

The agreement came into effect after a contract entered between the two sides on a 7500t/d supporting power station project with waste heat of cement in late March this year.

Sinoma EC, a patent-holding company specialized in energy-saving and emission-reduction, started cooperation with Lucky Cement in 2008.

Since then, it has undertaken several projects, including the Pezu Lines AB and CD waste heat recovery power plant with a generating capacity of 10 MW respectively, the 15 MW Karachi Line EFG power plant with waste heat, Karachi Line H waste heat boiler extension, etc.

Waste thermal energy is one of the largest sources of inexpensive and clean energy available.

Waste heat power generation, or Waste Heat to Power (WHP), is the process of recovering waste heat and using it to generate power with no combustion and no emissions.

Recovery of waste heat helps reduce energy costs for industrial processes. By using the waste heat to generate emission-free electricity, industrial users can put wasted energy back into the process that created it, route the power somewhere else in the facility, or sell it to the grid to support clean energy production, distribution and use.

Moreover, such practices are in conformity with the initiative to build a green CPEC.
