FLSmidth ® MHC Twin Shaft Breaker The ideal crusher for soft and sticky materials

Published

Shares

The MHC Twin shaft breaker crushes soft and sticky materials such as marl, clay, shale, coal etc. The breaker comes in two teeth configurations: one for ball mills and one for vertical mills. Each ensures a product size that is optimized for the mill type. The design features offer key benefits that includes:

  • Low specific power consumption
  • Stable and trouble-free operation
  • Minimizes generation of fines and reduces wear
  • Floor-mounted slide rail system facilitates maintenance and inspection
  • Built-in automatic lubrication systems
  • Cleaning teeth arrangement to prevent clogging
  • Easy to install, adjust and maintain
  • Long-life of tooth wear parts
  • Reliable to operate and low maintenance
  • Swift and easy replacement of wear parts
  • Compact design saves installation costs

Low power and low wear
MHC twin shaft breaker consists of a frame and two rotors, which are shafts with toothed discs. On entering the breaker, the raw materials fall on the rotors and are gripped by the teeth and crushed. Specific power consumption remains relatively low due to the cutting action of the teeth. The rotors run at low speed which helps to minimize fines generation and reduces wear on the replaceable parts.

Stable operation
The MHC drive station consists of an electric motor, which transmits power to the reducer via a pulley drive and a fluid coupling. The drive station is designed so that it will start even if large amounts of material are lying on top of the breaker rotors. Replaceable "cleaning teeth" fitted on the inside of the breaker frame prevent any clogging of the rotors. Design configurations of individual motors with VFD is also available for better handling of extreme sticky materials

Maximum protection
If a non-breakable piece of material gets trapped between the rotors, the fluid coupling will start to slip. A speed monitor on the rotor shafts will stop the main motor and send a signal to the CCR. Should this fail for some reason, the oil in the fluid coupling will heat up and activate a mechanical switch. In case this procedure also fails, a melting plug in the fluid coupling will melt (at a higher temperature) and the oil will leave the coupling. The coupling will then no longer transmit torque.

Easy installation, adjustments and maintenance

  • Installation of the breaker is simple. It is transported to site as preassembled unit and is delivered together with the drive station, the grease lubricating unit and the barrel pump.
  • The MHC Twin shaft breaker drive pulleys may be altered to achieve higher throughput or higher torque.
  • Minor adjustments of the output size can be made by altering the synchronization of the two rotors.
  • Automatic lubrication unit provides continuous lubrication to breaker bearings.
  • The condition of the wear parts is easily monitored by taking a glance inside the breaker.
  • Floor mounted slide rail system facilitates maintenance and inspection.
  • Tools and lifting yoke are supplied together with the breaker to facilitate quick and trouble-free maintenance, including replacement of wear parts.
  • Rotor teeth configuration for maximum grip and fine product.

Robust crushing system offering to maximize productivity
FLSmidth MHC crushing system comes with matching Apron Feeders and Chain Scrapers. The Apron Feeder ensures a steady flow of material to the crusher. Two apron feeders can be combined to form a raw material blending system. By positioning two apron feeders perpendicular to each other it is possible to feed the same crusher with two different materials at the same time. This option combines comminution and blending in one installation. The rugged and reliable construction makes FLSmidth Apron Feeder easy to operate and maintain, with minimum attention. The feeders are designed and built to last long with uninterrupted service, year after year.

Going forward, domestic steel mills are targeting capacity expansion
of nearly 40 per cent through till FY31, adding 80-85 mt, translating
into an investment pipeline of $ 45-50 billion. So, Jhunjhunwala points
out that continuing the safeguard duty will be vital to prevent a surge
in imports and protect domestic prices from external shocks. While in
FY26, the industry operating profit per tonne is expected to hold at
around $ 108, similar to last year, the industry’s earnings must
meaningfully improve from hereon to sustain large-scale investments.
Else, domestic mills could experience a significant spike in industry
leverage levels over the medium term, increasing their vulnerability to
external macroeconomic shocks.(~$ 60/tonne) over the past one month,
compressing the import parity discount to ~$ 23-25/tonne from previous
highs of ~$ 70-90/tonne, adds Jhunjhunwala. With this, he says, “the
industry can expect high resistance to further steel price increases.”

Domestic HRC prices have increased by ~Rs 5,000/tonne
“Aggressive
capacity additions (~15 mt commissioned in FY25, with 5 mt more by
FY26) have created a supply overhang, temporarily outpacing demand
growth of ~11-12 mt,” he says…

Price hikes, drop in input costs help cement industry to post positive margins: Care Ratings

Published

Region-wise,the southern region comprises 35% of the total cement capacity, followed by thenorthern, eastern, western and central region comprising 20%, 18%, 14% and 13%of the capacity, respectively.

The cement industry is expected to post positive margins on decent price hikes over the months, falling raw material prices and marked drop in overall production costs, said an analysis of Care Ratings.

Wholesale and retail prices of cement have increased 11.9% and 12.4%, respectively, in the current financial year. As whole prices have remained elevated in most of the markets in the months of FY20, against the corresponding period of the previous year.

Similarly, electricity and fuel cost have declined 11.9% during 9M FY20 due to drop in crude oil prices. Logistics costs, the biggest cost for cement industry, has also dropped 7.7% (selling and distribution) as the Railways extended the benefit of exemption from busy season surcharge. Moreover, the cost of raw materials, too, declined 5.1% given the price of limestone had fallen 11.3% in the same aforementioned period, the analysis said.

According to Care Ratings, though the overall sales revenue has increased only 1.3%, against 16% growth in the year-ago period, the overall expenditure has declined 3.2% which has benefited the industry largely given the moderation in sales.

Even though FY20 has been subdued in terms of production and demand, the fall in cost of production has still supported the cement industry by clocking in positive margins, the rating agency said.

Cement demand is closely linked to the overall economic growth, particularly the housing and infrastructure sector. The cement sector will be seeing a sharp growth in volumes mainly due to increasing demand from affordable housing and other government infrastructure projects like roads, metros, airports, irrigation.

The government’s newly introduced National Infrastructure Pipeline (NIP), with its target of becoming a $5-trillion economy by 2025, is a detailed road map focused on economic revival through infrastructure development.

The NIP covers a gamut of sectors; rural and urban infrastructure and entails investments of Rs.102 lakh crore to be undertaken by the central government, state governments and the private sector. Of the total projects of the NIP, 42% are under implementation while 19% are under development, 31% are at the conceptual stage and 8% are yet to be classified.

The sectors that will be of focus will be roads, railways, power (renewable and conventional), irrigation and urban infrastructure. These sectors together account for 79% of the proposed investments in six years to 2025. Given the government’s thrust on infrastructure creation, it is likely to benefit the cement industry going forward.

Similarly, the Pradhan Mantri Awaas Yojana, aimed at providing affordable housing, will be a strong driver to lift cement demand. Prices have started correcting Q4 FY20 onwards due to revival in demand of the commodity, the agency said in its analysis.

Industry’s sales revenue has grown at a CAGR of 7.3% during FY15-19 but has grown only 1.3% in the current financial year. Tepid demand throughout the country in the first half of the year has led to the contraction of sales revenue. Fall in the total expenditure of cement firms had aided in improving the operating profit and net profit margins of the industry (OPM was 15.2 during 9M FY19 and NPM was 3.1 during 9M FY19). Interest coverage ratio, too, has improved on an overall basis (ICR was 3.3 during 9M FY19).

According to Cement Manufacturers Association, India accounts for over 8% of the overall global installed capacity. Region-wise, the southern region comprises 35% of the total cement capacity, followed by the northern, eastern, western and central region comprising 20%, 18%, 14% and 13% of the capacity, respectively.

Installed capacity of domestic cement makers has increased at a CAGR of 4.9% during FY16-20. Manufacturers have been able to maintain a capacity utilisation rate above 65% in the past quinquennium. In the current financial year due to the prolonged rains in many parts of the country, the capacity utilisation rate has fallen from 70% during FY19 to 66% currently (YTD).

The campaign also marks Wonder Cement being the first ever cement brand to enter the world of IGTV…

ETBrandEquity

Cement manufacturing company Wonder Cement, has announced the launch of a digital campaign ‘Har Raah Mein Wonder Hai’. The campaign has been designed specifically to run on platforms such as Instagram, Facebook and YouTube.

#HarRaahMeinWonderHai is a one-minute video, designed and conceptualised by its digital media partner Triature Digital Marketing and Technologies Pvt Ltd. The entire journey of the cement brand from leaving the factory, going through various weather conditions and witnessing the beauty of nature and wonders through the way until it reaches the destination i.e., to the consumer is very intriguing and the brand has tried to showcase the same with the film.

Sanjay Joshi, executive director, Wonder Cement, said, "Cement as a product poses a unique marketing challenge. Most consumers will build their homes once and therefore buy cement once in a lifetime. It is critical for a cement company to connect with their consumers emotionally. As a part of our communication strategy, it is our endeavor to reach out to a large audience of this country through digital. Wonder Cement always a pioneer in digital, with the launch of our IGTV campaign #HarRahMeinWonderHai, is the first brand in the cement category to venture into this space. Through this campaign, we have captured the emotional journey of a cement bag through its own perspective and depicted what it takes to lay the foundation of one’s dreams and turn them into reality."

The story begins with a family performing the bhoomi poojan of their new plot. It is the place where they are investing their life-long earnings; and planning to build a dream house for the family and children. The family believes in the tradition of having a ‘perfect shuruaat’ (perfect beginning) for their future dream house. The video later highlights the process of construction and in sequence it is emphasising the value of ‘Perfect Shuruaat’ through the eyes of a cement bag.

Tarun Singh Chauhan, management advisor and brand consultant, Wonder Cement, said, "Our objective with this campaign was to show that the cement produced at the Wonder Cement plant speaks for itself, its quality, trust and most of all perfection. The only way this was possible was to take the perspective of a cement bag and showing its journey of perfection from beginning till the end."

According to the company, the campaign also marks Wonder Cement being the first ever cement brand to enter the world of IGTV. No other brand in this category has created content specific to the platform.
