Characteristics of stepped unit:
What are the Wall putty making machine of Unit Features？
The wall putty manufacturing machine and dry mortar plant feature a semi-stepped layout. Compared to a typical stepped unit, this design reduces the unit’s overall height. The metering and batching hopper is positioned on the ground, and the proportioned raw materials are lifted to the mixer via a bucket elevator. A finished product buffer hopper is installed below the mixer, and the valve bag fillers machine is positioned beneath the buffer hopper. The height of this unit is approximately 6-7 meters.
Scope of application:
Wall putty making machine Suitable for: All types of wall putty, tile adhesive mortar, cement-based mortar, gypsum plaster, gypsum adhesive, gypsum-based adhesive, lime-cement mortar, and other dry powder building materials.

Features Tips:
Since the typical smooth flow ladder design has been modified to a semi-ladder design, the dosed material now needs to be lifted to the mixer using a DTG-type bucket elevator, which takes additional time. This differs from the standard ladder design, where the metering and dosing bins are positioned above the mixer, allowing for quick discharge of material directly into the mixer.
Introduction to unit capacity:
Mini-Stepped Unit: The unit is distinguished based on the size of the mixer, with available mixer models being 2m³, 3m³, 4m³, and 6m³. Generally, the mixing time for the Dual Axis Gravity-Free Mixer is set to 120 seconds. Depending on the selected mixer model, the choice of screw conveyor, bucket elevator, dosage weighing hopper, and other components will also vary accordingly.
| Mixer Model | Total Power | Number of Packaging Machines |
|---|---|---|
| 2m³ | 10-15 | 2 |
| 3m³ | 15-20 | 2-3 |
| 4m³ | 30-35 | 4 |
| 6m³ | 40-50 | 4-5 |
Design elements:
Silo: Based on the customer’s formula and output requirements, select the appropriate number and volume of silos. Install dust removal devices, material level sensors, and load cells to display the weight or location of raw materials within the silo. For raw materials such as cement and gypsum powder, if bulk transport trucks with pneumatic conveying systems are used, design the silo with dust suppression pipes. The raw materials can be transported to the silo via vehicle pneumatic conveying without the need for a bucket conveyor.
Bucket Elevator: For dry sand, heavy calcium carbonate, calcium hydroxide, or other raw materials that are not transported via vehicle-mounted pneumatic conveying devices, use NE or DTG-type bucket elevators. The raw materials will be vertically lifted to the silo. Install a 2-way or 3-way distributor, allowing the bucket elevator to transport materials to different silos.
Screw Conveyor: Select the screw conveyor’s diameter and power according to the production speed. Typically, it is designed with a diameter of Φ219mm or Φ273mm.
Weighing Hopper: Equip the weighing hopper with precision load cells, pneumatic discharge valves, and pneumatic + mechanical vibration arch breakers to prevent raw materials from remaining in the hopper. To increase batching speed, 2 or 3 weighing hoppers can be installed simultaneously.
Mixer: The dual-axis gravity-free mixer uses a special hardened gear reducer. The two spindles run in opposite directions, and the paddles on each spindle cross each other at an angle. This arrangement allows the raw materials to move in a reciprocating motion, with shearing and throwing actions occurring in the paddle cross area. This creates a non-gravity drop state, ensuring high mixing efficiency and uniformity. The mixing time is typically set between 90-120 seconds.
Valve Bag Fillers: Packaging machines can be classified by their discharge mechanism into impeller type or air-floating type. For dry mortar containing dry sand, we recommend the air-floating packaging machine to reduce machine wear and speed up the discharge process. For wall putty products, we recommend the impeller-type packaging machine. Depending on the valve bag type, bags can be classified as either inner valve bags or outer valve bags. In the cement industry, inner valve bags are typically used, as they don’t require additional sealing after filling. However, in some regions, wall putty and dry mortar use outer valve bags, for which an ultrasonic heat-sealing packaging machine is recommended.
PLC Control System: The PLC control system monitors raw material levels in the silo, controls the flow direction of the distributor and bucket conveyor, and manages the dust collector’s operation. It also automates dosage settings for the weighing hopper, sets the mixing time, controls the mixer’s discharge door, and monitors the finished product’s buffer hopper. The program for each logic point can be adjusted, with up to 50 formula settings available. Logic point feedback, production records, and printing can be managed in fully automatic, semi-automatic, or manual modes. The working status is dynamically displayed on the screen.
