  Is it difficult to distinguish between dry mixed mortar and wet mixed mortar? Teach you how to easily choose mortar

  Ready-mixed mortar refers to a variety of mortar mixes produced by specialized manufacturers and used in construction projects. It is a new building material developed in recent years in China. According to different production methods, ready-mixed mortar can be divided into dry mixed mortar and wet mixed mortar two categories. So what are the differences between dry mixed mortar and wet mixed mortar? Dry mixed mortar: Dry mixed mortar is a dry mixture that evenly mixes dry materials and is supplied in bulk or bag form. It needs to be used after adding water or supporting liquid at the construction site and stirring it evenly. The storage period of dry mixed mortar is longer, usually 3 months or 6 months. Wet mortar: Wet mixed mortar is a wet mixed mixture composed of all components including water, which can be used directly on the construction site, but it needs to be used before the mortar sets, and the long storage time is not more than 24 hours. The difference between dry mortar and wet mortar: Mortar status and storage time are different: Wet mixed mortar, the finished product storage time is short, the length is not more than 24h, must be...

  Dryer Installation and Commissioning

  1. The installation of the dryer should be strictly in accordance with the requirements of the assembly drawing and the basic drawing. Before the installation of the dryer, its parts and auxiliary parts should be checked, cleaned, cleaned and complete. 2. Since the dryer is a long and large equipment, the installation should be carried out in this order and method: (1) Draw the foundation line: make the cross line, the elevation line, and the central marking buried on the foundation plate correctly to achieve convenient use, accuracy, and not to be covered after the installation of the frame. (2) Install the base and tug: level the position of the cushion iron, draw out the base and the center line of the tug, adjust it flat and straight according to the position of the drawing, first grouting the foundation hole, tighten the anchor bolts when the concrete reaches a certain strength, and then install the cylinder after passing the review. (3) Install the cylinder and the rolling ring: first install the rolling ring on the cylinder, fix the concave joint required to a positive and reverse staggered configuration, and adjust the thickness of the cushion iron, so that the contact...

  Triple Cylinder Drying Machine Features

  1. 20% of the imported products invested in the equipment are made of wear-resistant manganese plate, which is 3-4 times wear-resistant than ordinary steel plate. 2. the initial moisture of the material is 25%, and the final moisture is below 0.5-1%, which is the preferred product of various drying projects such as cement slag powder, dry powder mortar production line. 3. Increase the efficiency of more than 40% than the traditional single cylinder dryer. 4. The fuel can use white coal, bituminous coal, coal gangue, oil, gas, wood, biomass, etc., can bake 20-40mm lump material, granular material, powder material. 5. It is about 60% less than the single cylinder dryer, and the civil construction investment is about 60% less, and the installation is convenient. 6. No air leakage phenomenon, completely solve the difficulty of sealing. 7. discharge temperature ≤60 degrees, can be directly fed into the warehouse, no need to enter the cooling shed cooling. 8. The outer cylinder temperature is less than 60 degrees, the exhaust gas temperature is less than 120 degrees, and the service time of the dust removal equipment bag is more than 2 times longer. 9. Coal consumption is 1/3 of the single cylinder dryer,...

  Mixing Plant Production Management 6 Elements, So That the Secret of Mixing Plant Orderly

  First of all, let’s talk about which of the six major elements are they? 1. Personnel configuration: Personnel configuration is very important for the mixing plant, which should ensure normal production personnel without causing personnel waste. According to the absolute scale of the mixing plant, different job categories should be set and different numbers of personnel should be allocated. 2. Equipment: For concrete production, the mixing plant is the largest equipment, and all production activities revolve around the mixing plant. Therefore, equipment management is very important to ensure the normal operation of the machine, which requires regular maintenance and mastery of certain mixing plant maintenance techniques. 3. Production: Concrete production requires collaboration among various departments, from obtaining sales orders to issuing production tasks by the production department. The laboratory provides specific relevant mix proportions, the mixing plant operator inputs production tasks to start production, and multiple departments need to communicate more when the concrete arrives at the construction site. Once any errors occur in the intermediate links, irreversible problems will be produced. 4. Fleet management: Many mixing plants have their own fleet, including mixer trucks and pump trucks, both of which are important carriers for concrete transportation and construction. Therefore,...

  Dry Mortar Mixed Plant Overall Equipment Maintenance System

  1. After the completion of each work, the responsible personnel of the mixing station should clean up and maintain the project: (1) Clean up the ash accumulation inside and outside the wall of the mixing tank, the concrete residue on the discharge port, the mixing shaft and the discharge door, wash these places with water, and if necessary, put a small amount of stones and water into the mixing for a few minutes before releasing. Clean vehicle, additive tank and supply system with water. (2) Freezing season, at the end of the work, the pump, additive pump, water tank, additive tank, water, residual water and additive in the additive pipeline should be drained to prevent damage to the pump and its pipeline, and start the additive pump of the pump to run for 1-2 minutes. 2. dry mortar mixed plan weekly inspection maintenance items: (1) Whether the manual oil pump needs to be lubricated (2) Each lubrication point must be lubricated Note: The lubrication points are located at the gate shaft of the mixer, the gate shaft of the storage hopper and weighing hopper, the belt conveyor, the machine support wheel, the press wheel, the roller, the bearing, the transmission...

  What Kind of Sand Dryer is Commonly Used?

  What is commonly used is a three-cylinder dryer, the main features of the three-cylinder dryer: 1. High technical content, medium, inner cylinder self-insulation ability, high thermal energy utilization rate, low outlet temperature, greatly extend the service life of the dust collector. 2. Different lifting devices are used in different areas of the inner, middle and outer cylinder respectively, which can increase the lifting rate to about 40%, reduce the “wind tunnel”, increase the contact rate between boredom and hot air flow, and greatly increase the drying efficiency. 3. Synchronous drive with age support wheel, high rotation efficiency. 4. Small footprint, the use of the whole 100 bracket, easy installation, less failure rate, easy maintenance, basic investment. 5. The inlet and discharge device adopts structural soft seal, small air leakage rate, high thermal efficiency and low energy consumption. 6. The process flow can be downflow or counterflow. 7. Optimized structural design and heat-resistant treatment technology lay the foundation for long-term, trouble-free operation of the dryer. 8. According to the different nature of the material, the speed regulating motor or frequency converter is used to reasonably adjust the cylinder speed to increase the drying efficiency. 9. Using the principle of aerodynamics, the...
