How to improve the brick removal efficiency of pellet kiln? Efficiency is key in demolition. You only need to invest in one piece of Hitech equipment to reduce the downtime of your factory. If your factory is using a pellet kiln to smelt metal, you can follow me to learn how the equipment can improve efficiency. Problems during the construction of pellet kiln A pellet kiln is an equipment used for pelletization (making spherical particles) and is mainly used in metallurgy, fertilizers, building materials and other industries. A pellet kiln usually consists of a rotating cylinder and heating equipment. The raw materials are heated in the rotating cylinder and form spherical particles in the process. During the calcination process, rings will form on the surface of the pellet kiln refractory material, and the rings need to be cleaned regularly to avoid affecting the working efficiency of the rotary kiln. The internal refractory material of the pellet kiln is composed of refractory bricks and castables. The middle part of the kiln mouth is made of castables, making equipment construction the most difficult. What Hitech can bring you Saving time in construction means improving efficiency and profitability. The pellet kiln regularly needs to clean the rings and remove the bricks, and production needs to be stopped first for each construction. To solve this problem, it is necessary to reduce the downtime of the pellet kiln. The demolition robot has amazing demolition capabilities and can demolish bricks in the kiln efficiently and safely. The equipment is remotely operated. This brick removal process not only reduces the manual labor burden, but also effectively shortens the brick removal cycle and improves production efficiency. Step 1: Stop kiln operation Step 2: Move the device to the kiln entrance Step 3: Enter the kiln to work Hitech work preparation 1. Stop the kiln: Before dismantling the refractory materials, you must first stop the kiln, clean the kiln mouth and spray water to cool down and reduce dust. At the same time, use equipment to block the kiln body to prevent personnel from rotating the kiln body during construction and causing safety hazards. 2. Move the equipment to the kiln entrance: Use a crane to hoist the demolition robot to the kiln entrance (the basic condition of the equipment needs to be checked beforehand), connect the power supply and ensure that there are no obstacles in the passage. 3. Operation method: Slowly drive the equipment into the kiln mouth about 2 to 3 meters away and start construction. During construction in the kiln, no one else except the operator is allowed to enter. Cleaning up fallen refractory material should draw your attention during construction. This will directly affect your work efficiency. During the construction of the equipment for about 15 meters, it is necessary to clean up the fallen bricks in the kiln to prevent them from blocking normal driving. First, exit the equipment from the kiln entrance, rotate the kiln body for about 40 minutes, and clean the bricks out of the kiln. At the same time, a large amount of water needs to be sprayed at the discharge port to avoid problems such as excessive dust, environmental pollution, and personnel safety hazards. This step needs to be repeated in sequence during the subsequent removal of the refractory materials. Related data of Anhui Sichuan pellet kiln: Pellet kiln size: 5m×35m Refractory material thickness 250mm~280mm Cleaning up knots: about 4 months/time Removal of refractory materials: 1 year/time Kiln shutdown time: 24 hours Equipment movement method: crane Time for brick removal and kiln transfer: 40 minutes The demolition robot has demonstrated excellent performance in the application of brick demolition in pellet kilns, providing an efficient and reliable solution for the brick demolition task in industrial production.

Let's See How Demolition Robots Boost Efficiency in construction industry (As per Research by Industry Experts) Concrete contractors are finding ways to enhance productivity and worker safety while reducing bid prices, all thanks to the introduction of remote-control demolition robots into their sawing operations. The field of demolition, like every industry, is in a constant state of evolution. Contractors, to stay ahead of the curve, are exploring machinery and techniques that can augment productivity while reducing the physical strain on their workforce. Concrete sawing, a well-established technique for efficient material removal, has now embraced a transformative addition - remote-control demolition robots. This addition not only amplifies safety and versatility but also offers cost-saving advantages that can boost profitability for contractors. Here’s how. 1. Completing Jobs More Rapidly Let's consider a wall sawing task. The conventional approach to removing a 10-by-3-m (32.8-by-9.8 ft.) wall in a confined space using saws entails around 25 cuts, sometimes more depending on the depth. Subsequently, these cuts might need several passes. Afterward, the concrete blocks need to be further broken down for easier disposal. This conventional process takes at least four days and necessitates a crew of at least three - two to operate the saws and at least one more for debris handling. The introduction of a remote-control demolition robot can cut this time in half. While productivity rates vary depending on the machine, material, and depth, some demolition robots are capable of extraordinary output, reaching up to 5 cubic meters (176.6 cu. ft.) per hour in certain scenarios. Old-fashioned laborers were required to work on their hands and knees, drilling, breaking, and manually lifting concrete slabs. Furthermore, when cutting slabs for manual lifting, the concrete needed to be cut into smaller sections. In contrast, demolition robots can effortlessly cut through old concrete and lift a six-by-six slab without the need for manual labor. For the removal of the previously mentioned 10-by-3-m wall, perimeter cuts are still necessary to prevent vibration from affecting nearby structures. Following this, the demolition robot and a single operator can rapidly break up the concrete into more manageable pieces. Demolition robots can substantially reduce removal times for demanding tasks such as the removal of heavily reinforced concrete. The robot traverses the surface, breaking the concrete. This approach significantly reduces diamond costs when compared to standard methods like core drilling, wire sawing, and wall sawing. Additionally, these robots minimize the requirement for scaffolding on larger vertical demolition projects, with some models reaching heights of up to 5 m (16.4 ft.). This can save considerable time before and after the project, effectively shortening the job's duration and freeing up crews for additional revenue-generating tasks. 2. Ensuring Worker Safety The robots' extensive reach, coupled with a remote operating distance of 300 meters (984 ft.), helps keep workers out of harm’s way by reducing their exposure to jobsite hazards such as falling objects, flying debris, weakened floors, ledges, and harmful silica dust. Moreover, by automating manual aspects of concrete cutting, demolition robots significantly enhance worker safety. The need for handheld saws, coring equipment, or pneumatic breakers is notably reduced. Handheld pneumatic equipment, some of which can weigh 40 lbs. (18 kilograms) or more, can lead to worker fatigue and long-term injuries related to vibration. Robotic demolition also results in smaller rubble that is easier to handle and remove, further minimizing the physical strain on workers. 3. Versatility Through Attachments Attachments significantly expand jobsite versatility. For instance, a crusher attachment generates less noise than saws or handheld pneumatic breakers, enabling work in noise-sensitive areas such as those near hospitals or schools. A demolition robot equipped with a range of attachments not only boosts productivity but also reduces the need for additional support equipment on crowded jobsites. Crusher attachments facilitate the breaking and disposal of concrete and rebar directly on-site. Vacuum lifting attachments enhance efficiency when moving concrete slabs. Our demolition robots break, crush, cut, and lift. We offer a multitude of attachments for our machines, enhancing their versatility on concrete cutting jobsites. These include buckets, crushers, breakers, rock drills, shears, and plungers. The only limit to these robots is your imagination.
