Waste concrete crushing equipment

Introduction to concrete crushing equipment
Currently, the waste concrete crushing equipment are fixed and mobile two categories. For the production of recycled aggregate crushing plants can be fixed natural aggregate crushing equipment. Mobile crushing and screening equipment is evolved from the original fixed, and by a combination of stand-alone devices, and can be installed on mobile devices, easy to move the host device
At present, the representative mobile concrete crushing and screening equipment has the following three types:

1. large traction mobile crusher
Install a high-performance crusher, is set for the material, crushing, screening as one of the mobile production machinery.

Although it is characterized by mobile, but it is a feeder, primary and secondary crusher, magnetic separator and screening machines as one of the broken equipment. This machine has automatic feeding system to run unattended; the largest diameter in the same machinery, bulk materials can be processed; reasonably compact body design, taking into account the noise = dust impact on the environment; automation of production Efficiency is very high, capable of producing high-quality recycled aggregate.

2. medium-sized crawler crusher
This model is equipped with feeding system, concrete crushing equipment roll crusher and efficient screening system at the job site to the main purpose of crushing.

Two-axis roll crusher is equipped with a special type of strong crushing teeth, even if mixed with reinforced concrete, can easily be broken. Also, attached to the steel drum, but also through the roller running forward and reverse simply remove the broken. Machine production efficiency, environmental protection, but only the production of recycled coarse aggregate.

3. small mobile crusher
Aircraft due to demolition sites, construction sites and other on-site mobility and good production efficiency, has been highly acclaimed. Although they are small machine, but fully equipped and fully flexible features of the minicomputer. The machine installed feeder, they are able to feed and stable production, and can set the feed rate according to the situation of raw materials; low noise, vibration, help protect the environment, even if operating in the city affect the surrounding environment do not have to worry about ; use of rubber tracks, will not damage the ground; can install two conveyor and magnetic separator.
concrete crushing equipment application
1. bulk ore (metal mining, non-metallic minerals) break-up;
2. concrete components (cement road, machine foundation, bridges and housing components) partial and full demolition operations;
3. tunnels, ditches and other indoor or confined space, split the rock excavation or demolition work:
Methodology covers rock ripper, road removal, slope treatment, and many other projects. Hydraulic splitting machine operated rescue law, in the case of blasting is not allowed, compared to "hammer" method of operation, to create a better economic efficiency: save time, save money!

Caterpillar Leaps to the Top of Mining Equipment

Wow! Caterpillar Inc. announced it will purchase Bucyrus Intl. Inc.
(BII) for $7.6 billion cash plus assumption of $1 billion of BII debt
for a total transaction price of $8.6 billion or $92 per share, a 32%
premium to the BII closing price the day before. The deal is expected to
close in mid-2011.

This year BII will have revenues of approximately $3.75, which are all
<a href="http://www.mhmhd.com/spare-parts-for-mining-industry/">mining
</a>related. Caterpillar's estimated 2010 mining related revenues are
$3.9 billion. With only one possibly redundant product category between
the two companies (electric-drive trucks, where Cat products are still
in development), it is reasonable to add revenues from both companies
totaling $7.65 billion in mining equipment sales if they were one
company today.

More than 18% of Caterpillar's revenues would be from mining, making
Caterpillar far and away the largest manufacturer of mining equipment
worldwide. Komatsu is expected to have 2010 mining equipment revenues of
$4.8 billion and BII's direct competitor, Joy Global (P&H Mining
Equipment and Joy Mining Machinery), will have 2010 revenues of
approximately $3.4 billion.

International Mining Machinery Holdings Limited Announces Shanxi JV with Shanxi Coal Transportation

HONG KONG, Dec. 8, 2010 /PRNewswire-Asia/ -- International Mining
Machinery Holdings Limited ("IMM" or "the Company"; HKEx: 1683), a
leading designer and manufacturer of underground longwall coal mining
equipment in China, is pleased to announce that IMM has entered an
agreement with Shanxi Coal Transportation and Sales Group Co., Ltd.
("Shanxi Coal Transportation") to establish a joint venture to meet the
enormous demand for coal mining machinery in the rapidly consolidating
coal mining market in Shanxi. This landmark agreement is a significant
milestone for IMM, as it lays a solid foundation to add to the Company's
already rapid growth.

According to the terms of the agreement, the two parties will set up a
joint venture (the "JV"), under the name of Shanxi Meijia Mining
Machinery Company Limited, with Shanxi Coal Transportation holding 51%
and IMM controlling the remaining 49%. IMM will be responsible for the
daily management of the joint venture. With a 50-year term, the joint
venture company will be principally engaged in the production, sale and
marketing of roadheaders and other mining machinery. The two parties
have already signed the joint venture agreement, and the planning stage
of production, sales and operations for the joint venture is in full
swing. Production is expected to start by the end of 2011.

Pursuant to the JV agreement, the registered capital of the JV company
will be RMB69 million, RMB33.81 million of which will be contributed by
the Company (through a wholly-owned subsidiary, Jiamusi Machinery) with
the remaining RMB35.19 millionfrom Shanxi Coal Transportation through a
wholly- owned subsidiary. It is expected that the JV company will invest
aboutRMB83 million as an initial investment. Initially, the JV company
will focus on the production and sale of roadheaders and will later
include shearers, armoured- face conveyors and other coal mining machinery.

Shanxi Coal Transportation is a large, modernised coal mining and
logistics group established by the Shanxi State-owned Assets Management
Committee and 11 municipal state-owned assets management committees.
Shanxi Coal Transportation is engaged in a wide variety of coal-related
businesses, including the sale of coal and coke, coal and coke
technology development, the sale of coal chemicals and the production of
coal mining machinery. Shanxi Coal Transportation is an industry leader
with strong experience in the entire supply chain of coal, from
production and sales to transportation-related logistics. Shanxi Coal
Transportation, with an annual coal sales volume of about 200 million
tons, ranked as the second largest company among China's top 100 coal
enterprises in 2009 according to China National Coal Association and is
the 85th largest of China's top 500 enterprises in 2010 according to
China Enterprise Confederation.

As a leading coal enterprise, Shanxi Coal Transportation has rich
management experience and is a significant player inShanxi's coal mining
market. Shanxi Coal Transportation owns 163 modern coal mines sharing
the same centralised planning and procurement. It is expected that
Shanxi Coal Transportation will be producing more than 100 million tons
of coal annually in 3-5 years.

Shanxi is a key coal mining province with annual coal production
reaching 615 million tons. The province has an acute demand for coal
mining machinery, making it a strategic market with vast development
potential. The central government has placed a priority on the coal mine
consolidation in Shanxi province in order to lift overall productivity,
mine safety and quality of coal produced. In the last quarter of 2009,
the monthly coal production in Shanxi reached a record volume of 61.03
million tons. As the industry consolidation continues, hundreds of small
and non-mechanised mines will be closed and replaced by much bigger and
more modern mines. These new mines will require mining machinery from
companies such as the JV company. Moreover, the central government has
given top priority to mine safety and the demand for modern coal mining
machinery will continue to rise, providing the JV company with ample
development opportunities in the Shanxi market.

Mr. Thomas H. Quinn, Chairman of IMM, said, "Shanxi Coal Transportation
is a leading coal mining enterprise and we are delighted to partner with
such an impressive organisation. Apart from having strong backing from
the Shanxi provincial government, it is leading the industry in many
ways including a wide scope of businesses and services and an
outstanding management track record. We are confident that the joint
venture will achieve outstanding results based on the leading industry
position of Shanxi Coal Transportation and the progressive and talented
management of IMM."

Mr. Kee-Kwan Allen Chan, CEO of IMM, said, "The partnership with Shanxi
Coal Transportation is mutually beneficial, and will boost IMM's
competitiveness in such a huge market. The ongoing consolidation in the
coal mining industry gives rise to huge market opportunities, which the
joint venture company will successfully exploit to expand its market
share, given its geographical advantage in Shanxi."
