Architectural Waste Overview

The amount of urban construction waste continues to soar. A large amount of construction waste that has not been transported away from various places occupies a large amount of open space. Construction waste is constantly being produced, and the environmental pollution situation is increasingly severe. For a long time, a huge amount of construction waste has brought more pollution risks to the urban environment while affecting the lives of citizens. Due to the lack of unified and comprehensive construction waste management methods and standardized disposal sites, a large number of urban construction wastes are treated in a simple way such as throwing and landfilling.

Due to improper handling, construction waste often causes land occupation, random disposal of landfills, visible dust, and even sewage from garbage dumps on rainy days. It is only the tip of the iceberg where construction waste causes serious environmental pollution. It is understood that because construction adhesives, paints, paints, etc. in construction waste are difficult to degrade polymer materials and contain harmful heavy metal elements, they are buried underground, which will pollute the groundwater and directly endanger the lives of surrounding residents.

Urban construction waste is mainly bricks and concrete blocks generated when houses are demolished and roads are refurbished. After the construction waste is carried out, sandstone and concrete aggregates of different specifications can be obtained.

Concrete granules can be used for unrestricted roadbeds, agricultural and woodland roads, pedestrian and bicycle lanes, and concrete. Bricks, stone fragments or sand granules can be used for sports sites, gardens and scenic stone slabs, road bases, etc. Reasonable use of construction waste crushing equipment to treat construction waste, solve the negative impact on concrete waste treatment and environmental pollution, and reduce the exploitation of natural sand and gravel. The construction waste crushing system is divided into fixed type and mobile type, which are called fixed construction waste crushing station and mobile construction waste crushing station respectively, which are designed and configured according to different needs of users.

How to recycle construction waste:

1. Production of coarse and fine aggregates from abandoned building concrete and waste masonry, which can be used to produce concrete of corresponding strength grade;

2. The use of waste bricks to produce aggregates can be used to produce recycled bricks, blocks, wallboards, floor tiles and other building materials.

3. The use of waste muck can be used for road construction, pile foundation packing, foundation foundation, etc.

The use of construction waste to recover stone can eliminate damage to mines and rivers. Due to the requirements of environmental protection, there are more and more restrictions on the mining of gravel aggregates and the processing of stone materials in rivers, which makes the resources of gravel aggregates increasingly tight. The use of construction waste for the recovery of stone materials not only does not require the exploitation of natural resources, but also enables repeated recycling, which is one of the important ways for sand and gravel aggregates in the future.

Introduction To The River Cobble Sand Production Market
With the depletion of river sand resources, the artificial machinery sand market is becoming increasingly hot. A variety of ores can be used to produce machine-made sand, such as limestone, granite, tailings sand, and stone chips. River pebble sand is widely used in various places because of its vast resources. However, due to the high hardness of the river pebble and the large loss of metal, the cost of producing artificial sand from river pebble has been high. There are also a variety of river pebble sand making equipment on the market, such as impact crusher, rod mill, hammer crusher, counter-type sand making machine, hammerless grinding machine, vertical shaft counter-attack sand making machine, etc. . Due to the differences in raw materials and the habits of use, the application of machinery for producing mechanism sand varies widely. In some areas, traditional hammerhead crushers have been used, and in other areas, impact crushers are widely used. In some areas, roller crushers are widely used.

Characteristics of river pebble sand making:
First of all, the biggest characteristic of river pebbles is high hardness and strong abrasiveness, which will cause great wear and tear on the sand making equipment. Therefore, the river pebble production line should pay attention to the rationality of the process configuration, minimize the wear cost and obtain the maximum benefit.
Secondly, the river pebble sand production line has to face the problem of sand and gravel cleaning. Some river sands contain a large number of mud magazines, which cause a decrease in the quality of sand and gravel. When designing the river pebble sandstone production line, the sandstone must be fully cleaned, otherwise the quality and price of the sandstone will be reduced.
Finally, the river pebble sandstone production line should pay attention to avoid repeated crushing. The raw materials themselves contain a large number of sand and gravel materials that have met the grain size requirements. For these raw materials that have reached the particle size requirements, the reasonable process is advanced screening to avoid excessive repeated crushing. , thereby reducing power consumption and wear of the wear parts of the equipment.
River Pebbles Manufacturing Crushing Process
The mature process of the river pebble sand production line is: adopting the feeding machine with screening function, the raw material enters the chopper type stone breaking machine and the small material is directly screened out from the feeding machine, and the large piece of material passes through the E-type stone breaking machine. Treatment, the second break using fine smashing or cone breaking, processing the small and medium-sized materials in the raw materials and the broken materials in the raw materials. After the second breaking, the materials can be directly applied to the sand making equipment (counter-type sand making machine/vertical shaft impact breaking) After the shaping, the material is sent to the screening equipment for material feeding, and the material is returned to the sand making equipment, thereby entering the cycle of production and breaking.
In the crushing operation of the river pebble sand production line, we recommend to use the vertical shaft impact type sand making machine or the high efficiency counter type sand making machine as much as possible. Because the erosion of the river pebble is too strong, it will cause more serious wear on the hammer sand making machine, resulting in frequent replacement of the wear parts such as the hammer head, affecting the efficiency of the production line. The wear parts of the vertical shaft impact sand making machine are made of hard alloy and the wear time is the longest among all sand making machines. Between the investment cost and the production cost, the user needs to make a choice.

- The Second Stage
  The coarsely crushed perlite is screened by a vibrating screen and sent to a cone crusher (secondary crusher) for further crushing.
- The Third Stage
  If there are higher requirements for the obtained perlite grain type results, a sand making machine can be configured for shaping and crushing. The finely crushed perlite is sieved by a vibrating screen and sent to the finished product pile that meets the particle size requirements; the material that does not meet the requirements is returned to the crusher for further crushing.
- The Forth Stage
  The finished perlite is sent to a high-pressure washing system for washing operations. It can also be equipped with a wastewater recovery system and a dust purification system.
Investment Prospects
1) In order to improve the product performance of expanded perlite, the development of spherical non-porous expanded perlite should be developed as soon as possible. First, the perlite ore should be introduced into the furnace as near-spherical as possible instead of the irregular shape suitable for the previous grain size. Second, the structure of the kiln should be improved to increase the strength of the expanded perlite. 2) Perlite raw ore is finely pulverized, ultra-finely pulverized and chemically treated on the surface to become a mineral filler with certain functions. It can be widely used in rubber, plastic, cable, paint, ink and other industries.
3) Perlite has been used in animal feed and planting crops, and has achieved preliminary results, whether it is used as an animal feed additive, bedding material in chicken cages, fillers, anti-caking and fluidity additives, or as a veterinary agent, insecticide Agents, fertilizers, carriers of trace elements, absorbents or adsorbents, or for the separation of substrates and other purposes

Required Equipment
Jaw Crusher
The crushing structure of the jaw crusher is relatively simple. The machine mainly has a frame, an eccentric shaft, a large pulley, a flywheel, a movable raft, a side guard, a bracket, a bracket rear seat, a shimming screw, a return spring, and a fixed raft. It is composed of movable seesaws, etc., in which the brackets also play a role in insurance (when the crushing chamber enters the material that cannot be broken, the clamp of the crusher acts as an overload protection...
