40T/H wall putty making machine

Silo: According to the customer’s formula and output requirements, select the number and volume of silos. Install dust removal devices and material level devices to display the location of raw materials in the silo, or install load cells to display the weight of raw materials. For cement, gypsum powder, and other raw materials, if using bulk transportation trucks with vehicle pneumatic conveying, design the silo with a dust spraying pipe. Raw materials are transported to the silo through the vehicle pneumatic conveying system, so a bucket conveyor is not required.

Bucket Elevator: For dry sand, heavy calcium carbonate, calcium hydroxide, etc. (when raw materials are not transported using a vehicle-mounted pneumatic conveying device), use an NE-type bucket elevator or a DTG-type bucket elevator. The raw materials will be vertically lifted to the silo, with the installation of a 2-position or 3-position distributor, allowing the bucket elevator to transport raw materials to different silos.

Screw Conveyor: Select the diameter and power of the screw conveyor according to the production speed. It is usually designed as Φ219mm or Φ273mm.

Weighing Hopper: Equipped with a precision load cell, pneumatic discharge valve, and pneumatic arch breaker combined with a mechanical vibration arch breaker to prevent raw materials from staying in the hopper. To increase batching speed, 2 or 3 weighing hoppers can be set up simultaneously.

Mixer: The Dual Axis Gravity-Free Mixer uses a special hardened gear reducer, with two spindles running in opposite directions. The spindles have paddles crossing at an angle, allowing raw materials in the mixer to move in a reciprocating motion. The raw materials in the paddle cross area are sheared and thrown, creating a non-gravity drop state, resulting in high mixing efficiency and good uniformity. Mixing time is generally set at 90-120 seconds.

Valve Bag Fillers: Packaging machines can be divided by discharge principle into impeller or air-floating types. For various types of dry mortar, because the formula contains dry sand, we recommend using an air-floating packaging machine to reduce machine wear and speed up discharge. For wall putty products, we recommend using an impeller-type packaging machine. Based on the type of valve mouth bag, packaging can be classified into inner valve mouth bags and outer valve mouth bags. Generally, inner valve mouth bags are used in the cement industry (no need to seal after filling). In some areas, wall putty and dry mortar require the use of outer valve mouth bags, in which case, an ultrasonic heat-sealing packaging machine is recommended.

PLC Control System: Detects the position of raw materials in the silo, controls the flow direction of the distributor, dust collector, bucket conveyor, and manages the starting and stopping processes. It also handles automatic dosage setting of the weighing hopper, sets the working time of the mixer, controls the unloading door, and monitors the position of the finished product in the buffer hopper. The program for each logic point can be adjusted. It supports 50 kinds of formula editing, provides feedback for each logic point, stores production records, and allows printing. The system can operate in fully automatic, semi-automatic, or manual modes, with the working state dynamically displayed on the screen.
